　例えば特許文献１に記載されたバルブ装置では、弁体の回転軸に設けられたシャフトの端部は、内部空間を形成するハウジング本体の内壁から弁体とは反対側へ筒状に延びる軸受部により軸受けされている。
　そのため、内部空間内の空気が軸受部の内側に溜まるおそれがある。これにより、シャフトの端部と軸受部とが乾燥した状態で摺動するおそれがある。したがって、シャフトの端部または軸受部が摩耗するおそれがある。 For example, in the valve device described in Patent Document 1, the end portion of the shaft provided on the rotating shaft of the valve body has a bearing portion that extends in a cylindrical shape from the inner wall of the housing body that forms the internal space to the opposite side of the valve body. It is supported by.
Therefore, there is a possibility that air in the internal space is accumulated inside the bearing portion. Thereby, there exists a possibility that the edge part of a shaft and a bearing part may slide in the dry state. Therefore, the end of the shaft or the bearing may be worn.
　本開示の目的は、シャフトの端部の摩耗を抑制可能なバルブ装置を提供することにある。 An object of the present disclosure is to provide a valve device that can suppress wear of an end portion of a shaft.
＜９－１＞シャフト軸受部流路
　本開示は、車両の発熱体の冷却水を制御可能なバルブ装置であって、ハウジングとバルブとシャフト軸受部とを備えている。
　シャフト軸受部は、内部空間を形成するハウジング本体の内壁のうちシャフトの端部に対向する内壁である対向内壁から筒状に延び内側でシャフトの端部を軸受け可能な軸受部本体、および、軸受部本体の内周壁と外周壁とを接続するよう形成された軸受部流路を有している。 <9-1> Shaft Bearing Portion The present disclosure is a valve device capable of controlling the cooling water of a vehicle heating element, and includes a housing, a valve, and a shaft bearing portion.
A shaft bearing portion extends in a cylindrical shape from an opposing inner wall that is an inner wall facing the end portion of the shaft of the inner wall of the housing main body forming an internal space, and is capable of bearing the end portion of the shaft on the inside, and a bearing It has a bearing part channel formed so as to connect the inner peripheral wall and the outer peripheral wall of the main part.
　そのため、軸受部本体の内側に空気が溜まったとしても、軸受部流路を経由して当該空気を軸受部本体の外側へ排出することができる。これにより、シャフトの端部とシャフト軸受部とが乾燥した状態で摺動するのを抑制することができる。したがって、シャフトの端部またはシャフト軸受部が摩耗するのを抑制することができる。 Therefore, even if air accumulates inside the bearing unit body, the air can be discharged to the outside of the bearing unit body via the bearing unit flow path. Thereby, it can suppress that the edge part of a shaft and a shaft bearing part slide in the dry state. Therefore, it is possible to suppress wear of the end portion of the shaft or the shaft bearing portion.

　図３に示すように、回転軸Ａｘｒ１は、ハウジング本体２１の外部から駆動部カバー８０の外部まで延びるよう設定されている。つまり、回転軸Ａｘｒ１は、内部空間２００のみならず、ハウジング本体２１の外部においても存在する直線として定義される。シャフト３２は、軸が回転軸Ａｘｒ１に沿うようにして回転軸Ａｘｒ１上に設けられている。 As shown in FIG. 3, the rotation axis Axr1 is set to extend from the outside of the housing body 21 to the outside of the drive unit cover 80. That is, the rotation axis Axr1 is defined as a straight line that exists not only in the internal space 200 but also outside the housing body 21. The shaft 32 is provided on the rotation axis Axr1 such that the axis is along the rotation axis Axr1.
　弁体３１は、回転軸Ａｘｒ１周りに回転可能なよう内部空間２００に設けられている。シャフト３２は、回転軸Ａｘｒ１に沿う直線上に設けられている。つまり、シャフト３２は、回転軸Ａｘｒ１の少なくとも一部に設けられている。 The valve body 31 is provided in the internal space 200 so as to be rotatable around the rotation axis Axr1.

　シールユニット３５は、出口ポート２２１、２２２、２２３のそれぞれに設けられている。図４に示すように、シールユニット３５は、バルブシール３６、スリーブ３７１、スプリング３７２、シール部材３７３を有している。バルブシール３６は、例えば樹脂により略円環状に形成され、内側にシール開口部３６０を有している。バルブシール３６は、一方の面が弁体３１の外周壁に当接するよう設けられ、弁体３１の外周壁との間を液密に保持可能である。 The seal unit 35 is provided in each of the outlet ports 221, 222, and 223. As shown in FIG. 4, the seal unit 35 includes a valve seal 36, a sleeve 371, a spring 372, and a seal member 373. The valve seal 36 is formed in a substantially annular shape with, for example, resin, and has a seal opening 360 inside. The valve seal 36 is provided so that one surface thereof is in contact with the outer peripheral wall of the valve body 31, and can be liquid-tightly maintained between the valve seal 36 and the outer peripheral wall of the valve body 31.
　バルブシール３６は、例えばＰＴＦＥ（ポリテトラフルオロエチレン）に１４％のグラファイトおよび１％のＣＦ（カーボンファイバー）を混ぜた材料により形成されている。そのため、バルブシール３６は、弁体３１等と比べ、摩擦係数が低く、耐摩耗性、圧縮強度、耐クリープ性が向上している。 The valve seal 36 is made of, for example, a material in which PTFE (polytetrafluoroethylene) is mixed with 14% graphite and 1% CF (carbon fiber). Therefore, the valve seal 36 has a lower friction coefficient than the valve body 31 and the like, and has improved wear resistance, compressive strength, and creep resistance.
　スリーブ３７１は、例えば金属により筒状に形成され、一端でバルブシール３６を保持している。スリーブ３７１の他端は、パイプ部５１１の一端の内側に位置している。スプリング３７２は、スリーブ３７１の一端とパイプ部５１１の一端との間に設けられ、スリーブ３７１とともにバルブシール３６を弁体３１側へ付勢している。シール部材３７３は、例えばゴムにより環状に形成され、パイプ部５１１の一端とスリーブ３７１の外周壁との間に設けられ、パイプ部５１１とスリーブ３７１との間を液密に保持可能である。 The sleeve 371 is formed in a cylindrical shape from, for example, metal, and holds the valve seal 36 at one end. The other end of the sleeve 371 is located inside one end of the pipe portion 511. The spring 372 is provided between one end of the sleeve 371 and one end of the pipe portion 511, and urges the valve seal 36 together with the sleeve 371 toward the valve body 31. The seal member 373 is formed in an annular shape by rubber, for example, is provided between one end of the pipe portion 511 and the outer peripheral wall of the sleeve 371, and can hold the space between the pipe portion 511 and the sleeve 371 in a liquid-tight manner.
　スリーブ３７１は、例えばＳＵＳ４３０等のステンレスにより形成されている。そのため、スリーブ３７１の耐食性は、比較的高い。また、ＳＵＳ４３０はプレス性が良いため、スリーブ３７１を容易にプレス加工できる。 The sleeve 371 is made of stainless steel such as SUS430. Therefore, the corrosion resistance of the sleeve 371 is relatively high. Also, since SUS430 has good pressability, the sleeve 371 can be easily pressed.
　出口ポート２２２、２２３に設けられたシールユニット３５も、出口ポート２２１に設けられたシールユニット３５と同様の構成のため、説明を省略する。３つのシールユニット３５は、それぞれ、パイプ部５１１、５１２、５１３の一端に組み付けられている。 Since the seal units 35 provided at the outlet ports 222 and 223 are configured in the same manner as the seal unit 35 provided at the outlet port 221, description thereof will be omitted. The three seal units 35 are assembled to one ends of the pipe portions 511, 512, and 513, respectively.
　出口ポート２２２、２２３に設けられたシールユニット３５のスリーブ３７１、スプリング３７２、バルブシール３６は、出口ポート２２１に設けられたシールユニット３５のスリーブ３７１、スプリング３７２、バルブシール３６よりも外径が小さい。ここで、出口ポート２２１～２２３に設けられた各シールユニット３５のスプリング３７２のスプリング荷重は、バルブシール３６を圧縮してシールする必要漏れ量を満足する荷重に設定されている。出口ポート２２１～２２３に設けられた各シールユニット３５のスプリング３７２については、大小で漏れ目標が異なり、体格も異なるため、ばね定数も大小で異なる。 The sleeve 371, the spring 372, and the valve seal 36 of the seal unit 35 provided in the outlet ports 222 and 223 are smaller in outer diameter than the sleeve 371, the spring 372, and the valve seal 36 of the seal unit 35 provided in the outlet port 221. . Here, the spring load of the spring 372 of each seal unit 35 provided in the outlet ports 221 to 223 is set to a load that satisfies a necessary leakage amount for compressing and sealing the valve seal 36. About the spring 372 of each seal unit 35 provided in the exit ports 221 to 223, the leakage target is different depending on the size, and the physique is also different. Therefore, the spring constant is also different depending on the size.
　スプリング３７２は、例えばＳＵＳ３１６等のステンレスにより形成されている。そのため、スプリング３７２は、ばね性が良く、耐食性が高い。これにより、スプリング３７２の応力腐食割れを抑制できる。 The spring 372 is made of stainless steel such as SUS316. Therefore, the spring 372 has good spring properties and high corrosion resistance. Thereby, the stress corrosion cracking of the spring 372 can be suppressed.
　隔壁部６０は、例えば樹脂により形成されている。隔壁部６０は、ハウジング本体２１とは別体に形成されている。隔壁部６０は、隔壁部本体６１等を有している。隔壁部本体６１は、略円板状に形成されている。隔壁部６０は、隔壁部本体６１がハウジング開口部２１０を塞ぐようハウジング本体２１に設けられている。隔壁部６０は、隔壁部本体６１の中央を板厚方向に貫くシャフト挿通穴６２を有している。バルブ３０は、シャフト３２の一端がシャフト挿通穴６２を挿通するようにして設けられている。シャフト３２は、一端が隔壁部本体６１により軸受けされ、他端がハウジング本体２１により軸受けされている。 The partition wall 60 is made of, for example, resin. The partition wall 60 is formed separately from the housing body 21. The partition wall 60 has a partition wall body 61 and the like. The partition wall body 61 is formed in a substantially disk shape. The partition wall 60 is provided in the housing body 21 so that the partition wall body 61 closes the housing opening 210. The partition wall 60 has a shaft insertion hole 62 that penetrates the center of the partition wall body 61 in the thickness direction. The valve 30 is provided such that one end of the shaft 32 is inserted through the shaft insertion hole 62. One end of the shaft 32 is supported by the partition wall body 61 and the other end is supported by the housing body 21.

　駆動部７０は、駆動部空間８００に設けられ、シャフト３２の一端を経由して弁体３１を回転駆動可能である。駆動部７０は、モータ７１、ギア部７２等を有している。ギア部７２は、シャフト３２の一端に接続している。ＥＣＵ８がモータ７１への供給電力を制御すると、モータ７１の駆動力は、ギア部７２を経由してシャフト３２に伝達する。これにより、弁体３１が回転駆動する。 The drive unit 70 is provided in the drive unit space 800 and can rotate the valve body 31 via one end of the shaft 32. The drive unit 70 includes a motor 71, a gear unit 72, and the like. The gear part 72 is connected to one end of the shaft 32. When the ECU 8 controls the power supplied to the motor 71, the driving force of the motor 71 is transmitted to the shaft 32 via the gear portion 72. Thereby, the valve body 31 is rotationally driven.
　図５に示すように、リリーフポート２２４には、リリーフ弁３９が設けられている。リリーフ弁３９は、所定の条件、例えば冷却水の温度が所定の温度以上となったとき、開弁し、リリーフポート２２４を経由した内部空間２００とハウジング本体２１の外部すなわちパイプ部５１５の内側の空間との連通を許容し、冷却水の温度が所定の温度より低くなったとき、上記連通を遮断する。 As shown in FIG. 5, the relief port 224 is provided with a relief valve 39. The relief valve 39 is opened when a predetermined condition, for example, when the temperature of the cooling water is equal to or higher than a predetermined temperature, and is opened outside the internal space 200 and the housing body 21 via the relief port 224, that is, inside the pipe portion 515. The communication with the space is allowed, and when the temperature of the cooling water becomes lower than a predetermined temperature, the communication is cut off.
　図５に示すように、リリーフ弁３９は、バルブ間空間４００を間に挟んで入口ポート２２０と対向する位置に設けられている。すなわち、リリーフ弁３９は、入口ポート２２０から目視可能な位置に設けられている。より具体的には、リリーフ弁３９は、入口ポート２２０の軸方向から見たとき、少なくとも一部を目視可能である。 As shown in FIG. 5, the relief valve 39 is provided at a position facing the inlet port 220 with the inter-valve space 400 interposed therebetween. That is, the relief valve 39 is provided at a position where it can be seen from the inlet port 220. More specifically, the relief valve 39 is visible at least partially when viewed from the axial direction of the inlet port 220.
　そのため、入口ポート２２０から内部空間２００に流入した冷却水をリリーフ弁３９に直接当てることができ、冷却水の温度に応じてリリーフ弁３９を速やかに開弁させることができる。 Therefore, the cooling water flowing into the internal space 200 from the inlet port 220 can be directly applied to the relief valve 39, and the relief valve 39 can be quickly opened according to the temperature of the cooling water.
　図３、図６に示すように、隔壁部６０は、隔壁部本体６１の内部空間２００側の面から駆動部７０側へ凹むＣ字状の規制凹部６３が形成されている。規制凹部６３の周方向の端部間には、規制部６３１が形成されている。図３、図６に示すように、弁体３１には、駆動部７０側の端面から規制凹部６３側へ延びて先端部が規制凹部６３内に位置する第１規制凸部３３２、第２規制凸部３４２が形成されている。そのため、弁体３１は、第１規制凸部３３２が規制部６３１に当接したとき、および、第２規制凸部３４２が規制部６３１に当接したとき、その回転が規制される。つまり、弁体３１は、第１規制凸部３３２が規制部６３１に当接する位置から第２規制凸部３４２が規制部６３１に当接する位置までの範囲で回転可能である。 3 and 6, the partition wall 60 is formed with a C-shaped regulating recess 63 that is recessed from the surface of the partition wall body 61 on the inner space 200 side to the drive unit 70 side. A regulating portion 631 is formed between the circumferential ends of the regulating recess 63. As shown in FIGS. 3 and 6, the valve body 31 includes a first restriction convex portion 332 that extends from the end surface on the drive portion 70 side to the restriction concave portion 63 and has a tip portion located in the restriction concave portion 63. A convex portion 342 is formed. Therefore, the rotation of the valve body 31 is restricted when the first restriction convex part 332 comes into contact with the restriction part 631 and when the second restriction convex part 342 comes into contact with the restriction part 631. That is, the valve body 31 is rotatable in a range from a position where the first restriction convex part 332 contacts the restriction part 631 to a position where the second restriction convex part 342 contacts the restriction part 631.
　バルブ装置１０は、入口ポート２２０がウォータージャケット３の出口に接続するようエンジン２に取り付けられる。そのため、入口ポート２２０から内部空間２００に流入した冷却水は、バルブ間空間４００を経由して弁体内流路３００に流入する。また、弁体３１の回転により、弁体開口部４３０、４２０、４１０とそれぞれのシール開口部３６０とが重なったとき、その重なり面積に応じて冷却水が弁体内流路３００から弁体開口部４３０、４２０、４１０を経由してデバイス７、ヒータ６、ラジエータ５へ流れる。 The valve device 10 is attached to the engine 2 so that the inlet port 220 is connected to the outlet of the water jacket 3. Therefore, the cooling water that has flowed into the internal space 200 from the inlet port 220 flows into the valve body flow path 300 via the inter-valve space 400. Further, when the valve body openings 430, 420, 410 and the respective seal openings 360 are overlapped by the rotation of the valve body 31, the cooling water flows from the valve body flow path 300 to the valve body opening according to the overlapping area. It flows to the device 7, the heater 6, and the radiator 5 through 430, 420, and 410.
　ＥＣＵ８は、モータ７１の作動を制御し、弁体３１の回転位置を制御することにより、デバイス７に冷却水を流し、デバイス７において熱交換できるため、エンジンオイルやＥＧＲガスを冷却して燃費を向上できる。また、ヒータ６に冷却水を流し、車両１内の空気と冷却水との間で熱交換できるため、車両１内を暖めることができる。 The ECU 8 controls the operation of the motor 71 and controls the rotational position of the valve body 31 so that cooling water can flow through the device 7 and heat exchange can be performed in the device 7. Therefore, the engine oil and EGR gas are cooled to improve fuel efficiency. Can be improved. Moreover, since cooling water can be flowed through the heater 6 and heat can be exchanged between the air in the vehicle 1 and the cooling water, the inside of the vehicle 1 can be warmed.
　図７は、弁体３１の回転位置（横軸）と、弁体開口部４３０、４２０、４１０の開閉状態（縦軸）、すなわち、弁体開口部４３０、４２０、４１０とそれぞれのシール開口部３６０との重なり面積との関係を示す図である。ここで、弁体開口部４３０、４２０、４１０とそれぞれのシール開口部３６０との重なり面積は、デバイス７、ヒータ６、ラジエータ５への冷却水の流路面積に対応している。 7 shows the rotational position (horizontal axis) of the valve body 31 and the open / closed state (vertical axis) of the valve body openings 430, 420, 410, that is, the valve body openings 430, 420, 410 and the respective seal openings. It is a figure which shows the relationship with 360 and an overlapping area. Here, the overlapping area of the valve body openings 430, 420, 410 and the respective seal openings 360 corresponds to the flow path area of the cooling water to the device 7, the heater 6, and the radiator 5.
　ＥＣＵ８は、ヒータ６に冷却水を流す要求（ヒータ要求）がある場合に使用される「通常モード」と、ヒータ要求がない場合に使用される「ヒータカットモード」とを選択し、弁体３１を回転させる。「通常モード」と「ヒータカットモード」とは、全ての弁体開口部４３０、４２０、４１０が弁体３１の外周壁により閉じられて（全閉状態：図３参照）、デバイス７、ヒータ６、ラジエータ５への冷却水の流量がゼロとなる領域（領域ｄ）を隔てている。領域ｄでは、デバイス７、ヒータ６、ラジエータ５への冷却水の流れは遮断されている。 The ECU 8 selects a “normal mode” used when there is a request to flow cooling water through the heater 6 (heater request) and a “heater cut mode” used when there is no heater request, and the valve body 31. Rotate. In the “normal mode” and the “heater cut mode”, all the valve body openings 430, 420, and 410 are closed by the outer peripheral wall of the valve body 31 (fully closed state: see FIG. 3). A region (region d) where the flow rate of the cooling water to the radiator 5 is zero is separated. In the region d, the flow of cooling water to the device 7, the heater 6, and the radiator 5 is blocked.
　「通常モード」では、ヒータ６への通水が最優先される。図７において、領域ｄから右に進む方向に弁体３１を回転させると、弁体３１の回転位置が領域ｄの隣の領域（領域ｃ）に移行する。領域ｃでは弁体開口部４２０が開き始め、ヒータ６に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４２０が完全に開き、弁体３１の回転位置が領域ｃの隣の領域（領域ｂ）に移行する。領域ｂでは弁体開口部４３０が開き始め、デバイス７に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４３０が完全に開き、弁体３１の回転位置が領域ｂの隣の領域（領域ａ）に移行する。領域ａでは弁体開口部４１０が開き始め、ラジエータ５に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４１０が完全に開く（全開状態）。なお、弁体開口部４１０が完全に開かれる弁体３１の回転位置が弁体３１の回転限界（Ｒｏｔａｔｉｏｎ　ｌｉｍｉｔ）に相当し、このとき、第１規制凸部３３２は規制部６３１に当接している（図６参照）。 In the “normal mode”, the water flow to the heater 6 has the highest priority. In FIG. 7, when the valve body 31 is rotated in the direction proceeding to the right from the region d, the rotational position of the valve body 31 is shifted to a region (region c) adjacent to the region d. In the area c, the valve element opening 420 starts to open, and the cooling water starts to flow into the heater 6. When the valve body 31 is further rotated, the valve body opening 420 is completely opened, and the rotational position of the valve body 31 is shifted to a region (region b) adjacent to the region c. In the region b, the valve body opening 430 starts to open, and the cooling water starts to flow into the device 7. When the valve body 31 is further rotated, the valve body opening 430 is completely opened, and the rotational position of the valve body 31 shifts to a region (region a) adjacent to the region b. In the region a, the valve body opening 410 starts to open, and the cooling water starts to flow into the radiator 5. When the valve body 31 is further rotated, the valve body opening 410 is completely opened (fully opened state). Note that the rotational position of the valve body 31 at which the valve body opening 410 is completely opened corresponds to the rotation limit of the valve body 31, and at this time, the first restriction convex part 332 is in contact with the restriction part 631. (See FIG. 6).
　「ヒータカットモード」では、ヒータ６への通水は行われず、ラジエータ５よりもデバイス７への通水が優先される。図７において、領域ｄから左に進む方向に弁体３１を回転させると、領域ｄの隣の領域（領域ｅ）に移行する。領域ｅでは弁体開口部４３０が開き始め、デバイス７に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４３０が完全に開き、弁体３１の回転位置が領域ｅの隣の領域（領域ｆ）に移行する。領域ｆでは弁体開口部４３０のみが開き、デバイス７にのみ冷却水が流れる。さらに弁体３１を回転させると、弁体３１の回転位置が領域ｆの隣の領域（領域ｇ）に移行する。領域ｇでは弁体開口部４１０が開き始め、ラジエータ５に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４１０が完全に開く。ＥＣＵ８は、図７に示す「通常モード」と「ヒータカットモード」とに基づき弁体３１を回転駆動することにより、燃費と空調性能の両立を図ることが可能である。 In the “heater cut mode”, water is not passed to the heater 6, but water is given priority to the device 7 over the radiator 5. In FIG. 7, when the valve body 31 is rotated in a direction that proceeds to the left from the region d, the region shifts to a region adjacent to the region d (region e). In the region e, the valve body opening 430 starts to open, and the cooling water starts to flow into the device 7. When the valve body 31 is further rotated, the valve body opening 430 is completely opened, and the rotational position of the valve body 31 is shifted to a region (region f) adjacent to the region e. In the region f, only the valve body opening 430 is opened, and cooling water flows only to the device 7. When the valve body 31 is further rotated, the rotational position of the valve body 31 shifts to a region (region g) adjacent to the region f. In the region g, the valve body opening 410 starts to open, and the cooling water starts to flow into the radiator 5. When the valve body 31 is further rotated, the valve body opening 410 is completely opened. The ECU 8 can achieve both fuel efficiency and air conditioning performance by rotationally driving the valve body 31 based on the “normal mode” and the “heater cut mode” shown in FIG.
　図２に示すように、エンジン２には、インテークマニホールド１１、オルタネータ１２、ウォーターポンプ４、コンプレッサ１３、スタータ１４、トランスミッション１５等が組付けられている。バルブ装置１０は、オルタネータ１２とインテークマニホールド１１との間の狭小空間Ａ１においてエンジン２に取り付けられる。ここで、バルブ装置１０は、駆動部７０側が鉛直方向下側を向くようにしてエンジン２に取り付けられる。そのため、内部空間２００等で発生したベーパ等の空気は、鉛直方向上側へ移動し、パイプ部５１６を経由してリザーバタンクに排出される。 As shown in FIG. 2, the engine 2 is assembled with an intake manifold 11, an alternator 12, a water pump 4, a compressor 13, a starter 14, a transmission 15, and the like. The valve device 10 is attached to the engine 2 in a narrow space A1 between the alternator 12 and the intake manifold 11. Here, the valve device 10 is attached to the engine 2 such that the drive unit 70 side faces downward in the vertical direction. Therefore, air such as vapor generated in the internal space 200 or the like moves upward in the vertical direction and is discharged to the reservoir tank via the pipe portion 516.
　図２に示すように、バルブ装置１０が配置される狭小空間Ａ１は、水平方向に並ぶようにしてエンジン２に取り付けられるオルタネータ１２とインテークマニホールド１１との間に形成される。また、狭小空間Ａ１の鉛直方向下側には、コンプレッサ１３が配置される。そのため、狭小空間Ａ１に設けられたバルブ装置１０は、オルタネータ１２、インテークマニホールド１１およびコンプレッサ１３により囲まれた状態となる。 As shown in FIG. 2, the narrow space A1 in which the valve device 10 is arranged is formed between the alternator 12 and the intake manifold 11 that are attached to the engine 2 so as to be aligned in the horizontal direction. In addition, a compressor 13 is disposed below the narrow space A1 in the vertical direction. Therefore, the valve device 10 provided in the narrow space A1 is surrounded by the alternator 12, the intake manifold 11, and the compressor 13.
＜１－２＞ハウジング締結穴
　図８、図９、図１０に示すように、ハウジング２０は、ハウジング本体２１と一体に形成された締結部２３１、２３２、２３３を有している。締結部２３１、２３２、２３３は、ハウジング本体２１の取付面２０１側の端部から取付面２０１の面方向に突出するよう形成されている。また、ハウジング２０は、締結部２３１、２３２、２３３のそれぞれに対応して形成された締結穴２４１、２４２、２４３を有している。ここで、締結穴２４１、２４２、２４３は、それぞれ、「第１締結穴」、「第２締結穴」、「第３締結穴」に対応している。 <1-2> Housing Fastening Hole As shown in FIGS. 8, 9, and 10, the housing 20 has fastening portions 231, 232, and 233 formed integrally with the housing main body 21. The fastening portions 231, 232, and 233 are formed so as to protrude in the surface direction of the mounting surface 201 from the end of the housing body 21 on the mounting surface 201 side. The housing 20 has fastening holes 241, 242, 243 formed corresponding to the fastening portions 231, 232, 233, respectively. Here, the fastening holes 241, 242, and 243 correspond to a “first fastening hole”, a “second fastening hole”, and a “third fastening hole”, respectively.
　締結穴２４１、２４２、２４３には、締結部材２４０が挿通され、エンジン２に締結される。これにより、バルブ装置１０がエンジン２に取り付けられる。取付面２０１の入口ポート２２０の径方向外側には、環状ゴム製のポートシール部材２０９が設けられる。ポートシール部材２０９は、バルブ装置１０がエンジン２に取り付けられた状態において、締結部材２４０の軸力により圧縮された状態となる。これにより、ポートシール部材２０９は、取付面２０１とエンジン２との間を液密に保持し、入口ポート２２０から取付面２０１とエンジン２との間を経由して冷却水が漏れるのを抑制できる。 The fastening member 240 is inserted into the fastening holes 241, 242, and 243 and fastened to the engine 2. Thereby, the valve device 10 is attached to the engine 2. An annular rubber port seal member 209 is provided on the outer side in the radial direction of the inlet port 220 of the mounting surface 201. The port seal member 209 is compressed by the axial force of the fastening member 240 when the valve device 10 is attached to the engine 2. As a result, the port seal member 209 can keep the mounting surface 201 and the engine 2 in a liquid-tight state, and can prevent the coolant from leaking from the inlet port 220 through the mounting surface 201 and the engine 2. .
　ポートシール部材２０９は、例えばＥＰＤＭ（エチレンプロピレンゴム）等のゴムにより形成されている。そのため、コストを低減できる。なお、ポートシール部材２０９は、例えばＨ－ＮＢＲにより形成してもよい。この場合、ポートシール部材２０９の耐油性を向上できる。また、ポートシール部材２０９は、例えばＦＫＭにより形成してもよい。この場合、ポートシール部材２０９の耐水性および耐熱性を向上できる。そのため、熱の影響を受けやすいエンジン部品として採用するのに好適である。 The port seal member 209 is made of rubber such as EPDM (ethylene propylene rubber). Therefore, cost can be reduced. The port seal member 209 may be formed of H-NBR, for example. In this case, the oil resistance of the port seal member 209 can be improved. Further, the port seal member 209 may be formed by, for example, FKM. In this case, the water resistance and heat resistance of the port seal member 209 can be improved. Therefore, it is suitable for use as an engine component that is easily affected by heat.
　図９、図１０に示すように、締結穴２４１は、取付面２０１における入口ポート２２０の開口の径方向外側に形成されている。締結穴２４２は、締結穴２４１との間に入口ポート２２０の開口を挟むようにして形成されている。締結穴２４３は、締結穴２４１、２４２に対し駆動部７０側に形成されている。 As shown in FIGS. 9 and 10, the fastening hole 241 is formed on the radially outer side of the opening of the inlet port 220 in the mounting surface 201. The fastening hole 242 is formed so as to sandwich the opening of the inlet port 220 between the fastening hole 241. The fastening hole 243 is formed on the drive unit 70 side with respect to the fastening holes 241 and 242.

　上述のように、本実施形態は、車両１のエンジン２の冷却水を制御可能なバルブ装置１０であって、ハウジング２０とバルブ３０と隔壁部６０と駆動部７０とを備える。 <1-2>
As described above, the present embodiment is a valve device 10 that can control the cooling water of the engine 2 of the vehicle 1, and includes the housing 20, the valve 30, the partition wall portion 60, and the drive portion 70.
　ハウジング２０は、内側に内部空間２００を形成するハウジング本体２１、ハウジング本体２１の外壁に形成されエンジン２に取り付けられた状態においてエンジン２に対向する取付面２０１、取付面２０１に開口し内部空間２００とハウジング本体２１の外部とを接続する入口ポート２２０、ハウジング本体２１と一体に形成された複数の締結部（２３１、２３２、２３３）、および、複数の締結部のそれぞれに対応して形成された複数の締結穴（２４１、２４２、２４３）を有する。 The housing 20 has a housing main body 21 that forms an internal space 200 on the inner side, an attachment surface 201 that faces the engine 2 when formed on the outer wall of the housing main body 21 and is attached to the engine 2, and opens to the mounting surface 201. And the outside of the housing main body 21, the plurality of fastening portions (231, 232, 233) formed integrally with the housing main body 21, and the plurality of fastening portions, respectively. It has a plurality of fastening holes (241, 242, 243).
　バルブ３０は、内部空間２００内において回転軸Ａｘｒ１周りに回転可能な弁体３１、弁体３１の内側に形成され入口ポート２２０に連通可能な弁体内流路３００、および、回転軸Ａｘｒ１に設けられたシャフト３２を有する。 The valve 30 is provided in a valve body 31 that can rotate around the rotation axis Axr1 in the internal space 200, a valve body passage 300 that is formed inside the valve body 31 and that can communicate with the inlet port 220, and the rotation axis Axr1. A shaft 32.
　隔壁部６０は、内部空間２００とハウジング本体２１の外部とを隔てる。 The partition wall 60 separates the internal space 200 from the outside of the housing body 21.
　駆動部７０は、隔壁部６０に対し内部空間２００とは反対側に設けられ、シャフト３２を経由して弁体３１を回転駆動可能である。 The drive unit 70 is provided on the side opposite to the internal space 200 with respect to the partition wall unit 60, and can rotate the valve body 31 via the shaft 32.
　ハウジング本体２１は、締結穴（２４１、２４２、２４３）を通りエンジン２に螺合する締結部材２４０によりエンジン２に固定される。 The housing body 21 is fixed to the engine 2 by a fastening member 240 that is screwed into the engine 2 through the fastening holes (241, 242, 243).
　締結穴は、入口ポート２２０の開口の径方向外側に形成された第１締結穴（２４１）、第１締結穴との間に入口ポート２２０の開口を挟むよう形成された第２締結穴（２４２）、および、第１締結穴および第２締結穴に対し駆動部７０側に形成された第３締結穴（２４３）を含む。 The fastening holes are a first fastening hole (241) formed radially outside the opening of the inlet port 220, and a second fastening hole (242) formed so as to sandwich the opening of the inlet port 220 between the first fastening hole. ), And a third fastening hole (243) formed on the drive unit 70 side with respect to the first fastening hole and the second fastening hole.
　第１締結穴（２４１）は、第３締結穴（２４３）と同様、入口ポート２２０の中心よりも駆動部７０側に形成されている。 The 1st fastening hole (241) is formed in the drive part 70 side rather than the center of the inlet port 220 similarly to the 3rd fastening hole (243).
　そのため、入口ポート２２０の周りに環状の弾性部材からなるポートシール部材２０９を設けた場合、締結穴２４１および締結穴２４２を通る締結部材２４０によりハウジング本体２１をエンジン２に固定したとき、ポートシール部材２０９をバランスよく圧縮できる。これにより、入口ポート２２０周りのシール性を効果的に確保できる。 Therefore, when the port seal member 209 made of an annular elastic member is provided around the inlet port 220, when the housing body 21 is fixed to the engine 2 by the fastening member 240 passing through the fastening hole 241 and the fastening hole 242, the port seal member 209 can be compressed in a balanced manner. Thereby, the sealing performance around the inlet port 220 can be effectively secured.
　また、締結穴２４３を通る締結部材２４０により締結部２３３がエンジン２に固定されることにより、エンジン２の振動の駆動部７０への影響を抑制することができる。 Further, the fastening portion 233 is fixed to the engine 2 by the fastening member 240 passing through the fastening hole 243, so that the influence of the vibration of the engine 2 on the driving portion 70 can be suppressed.

　締結穴２４３と駆動部７０との距離は、締結穴２４３と入口ポート２２０の開口の中心Ｃｐ１との距離より短い。 <1-2-3>
The distance between the fastening hole 243 and the drive unit 70 is shorter than the distance between the fastening hole 243 and the center Cp1 of the opening of the inlet port 220.
　そのため、エンジン２の振動の駆動部７０への影響をより抑制することができる。 Therefore, the influence of the vibration of the engine 2 on the drive unit 70 can be further suppressed.

　締結穴２４３は、中心が、出口ポート２２３の中心を通り回転軸Ａｘｒ１に直交する仮想平面Ｖｐ２に対し駆動部７０側に位置するよう形成されている（図８参照）。なお、モータ７１は、締結穴２４３の軸方向から見たとき、重心Ｃｇ１が回転軸Ａｘｒ１に対し締結穴２４３側に位置するよう設けられている（図８、図９参照）。 <1-2-4>

　長手方向リブ２８６は、回転軸Ａｘｒ１方向に延びている。つまり、入口ポート２２０の軸方向から見た場合、長手方向リブ２８６と回転軸Ａｘｒ１とは重なっている（図９参照）。そのため、取付面２０１に垂直な方向の変形を抑制できる。仮に、このような変形が生じた場合、バルブ装置１０内部の部品がずれて、内部や外部への冷却水漏れを引き起こし、バルブ装置１０の機能が悪化するおそれがある。本実施形態は、このような問題を抑制できる。 The longitudinal rib 286 extends in the direction of the rotation axis Axr1. That is, when viewed from the axial direction of the inlet port 220, the longitudinal rib 286 and the rotation axis Axr1 overlap (see FIG. 9). Therefore, deformation in a direction perpendicular to the attachment surface 201 can be suppressed. If such deformation occurs, the components inside the valve device 10 may be displaced, causing cooling water leakage to the inside or outside, and the function of the valve device 10 may deteriorate. This embodiment can suppress such a problem.

　取付面凹部２０７をバルブ３０が設けられる内部空間２００とは反対側に設けることにより、バルブ３０が設けられる空間のない壁面が均肉になり、内部空間２００の空間精度が向上する。内部空間２００の空間精度が良いと壁面抵抗が減り、圧力損失を低減できる。 By providing the mounting surface recess 207 on the side opposite to the internal space 200 where the valve 30 is provided, the wall surface without the space where the valve 30 is provided becomes uniform, and the spatial accuracy of the internal space 200 is improved. When the space accuracy of the internal space 200 is good, the wall resistance is reduced and the pressure loss can be reduced.

The housing body 21 is made of polyphenylene sulfide resin (PPS) containing a filler. More specifically, the housing body 21 is made of “PPS-GF50” (PPS: 50%, glass fiber: 50%). As the filler, carbon fiber, silica fiber, silica, talc, silicon or the like can be used in addition to glass fiber.
　そのため、ハウジング本体２１の耐熱性、耐吸水性、強度、寸法精度を向上できる。 Therefore, the heat resistance, water absorption resistance, strength, and dimensional accuracy of the housing body 21 can be improved.

　弁体３１、ハウジング本体２１、隔壁部６０を同じ樹脂材料で形成することにより、線膨張差をなくすことができ、かじりを少なくすることができる。仮に、各部材間に線膨張差があると、冷却水漏れが生じるおそれがある。本実施形態は、このような問題を抑制できる。 By forming the valve body 31, the housing main body 21, and the partition wall portion 60 from the same resin material, it is possible to eliminate a difference in linear expansion and reduce galling. If there is a difference in linear expansion between the members, cooling water leakage may occur. This embodiment can suppress such a problem.
　弁体３１、ハウジング本体２１、隔壁部６０をＰＰＳにより形成することで、弁体３１、ハウジング本体２１、隔壁部６０の強度、耐熱性、耐薬品性を向上できる。 By forming the valve body 31, the housing body 21, and the partition wall portion 60 from PPS, the strength, heat resistance, and chemical resistance of the valve body 31, the housing body 21, and the partition wall portion 60 can be improved.
　パイプ部材５０は、例えばＰＰＡ（ポリフタルアミド）により形成されている。これにより、パイプ部材５０を無理抜きにより形成できる。 The pipe member 50 is made of, for example, PPA (polyphthalamide). Thereby, the pipe member 50 can be formed by forcibly removing.
　ＰＰＳで形成された弁体３１、ハウジング本体２１、隔壁部６０の線膨張係数は、ＰＰＡで形成されたパイプ部材５０の線膨張係数より小さい。そのため、熱がかかったときの歪みやアッシーへの影響を低減できる。 The linear expansion coefficient of the valve body 31, the housing body 21, and the partition wall portion 60 formed of PPS is smaller than the linear expansion coefficient of the pipe member 50 formed of PPA. Therefore, the influence on distortion and assembly when heat is applied can be reduced.
　他の実施形態では、弁体３１、ハウジング本体２１、隔壁部６０は、ＰＰＡにより形成してもよい。 In other embodiments, the valve body 31, the housing body 21, and the partition wall portion 60 may be formed of PPA.

　そのため、締結部２３１、２３２、２３３の肉厚を均肉にすることができる。その結果、ボイドの発生を防ぐことができ、締結部２３１、２３２、２３３の締結穴２４１、２４２、２４３に設けられるカラー周りの樹脂強度が低下することを抑制できる。さらに、エンジン２からの振動でカラー周りの薄肉が先に割れた場合にも、取付面凹部２０７がある結果、割れが内部空間２００まで至ることを抑制できる。 Therefore, the thickness of the fastening portions 231, 232, 233 can be made uniform. As a result, the generation of voids can be prevented, and the resin strength around the collar provided in the fastening holes 241, 242, and 243 of the fastening portions 231, 232, and 233 can be suppressed from decreasing. Furthermore, even when the thin wall around the collar is cracked first by vibration from the engine 2, it is possible to prevent the crack from reaching the internal space 200 as a result of the mounting surface recess 207.

Moreover, the number of members can be reduced.
　図１１に示すように、隔壁部本体６１の内部空間２００側の面のうち規制凹部６３の内側の部分は、規制凹部６３の外側の部分よりもやや内部空間２００側に位置している。 As shown in FIG. 11, the inner portion of the restriction recess 63 in the inner space 200 side surface of the partition wall body 61 is located slightly closer to the inner space 200 than the outer portion of the restriction recess 63.
　隔壁部本体６１と対向するハウジング本体２１の内周部分は、段差形状になっている。 The inner peripheral portion of the housing body 21 facing the partition wall body 61 has a step shape.
　環状シール部材６００が設けられる隔壁部本体６１とハウジング開口部２１０との間の隙間は、テーパ状に形成されている。これにより、環状シール部材６００を当該隙間に容易に設けることができる。当該隙間にエンジンオイルが侵入すると、環状シール部材６００が膨潤し、切れ、冷却水が漏れるおそれがある。また、環状シール部材６００が噛み込むと、環状シール部材６００が切れ、冷却水が漏れ、外部から内部にエンジンオイルが侵入するおそれがある。本実施形態では、この問題を抑制できる。 The clearance gap between the partition part main body 61 and the housing opening part 210 in which the annular seal member 600 is provided is formed in a taper shape. Thereby, the annular seal member 600 can be easily provided in the gap. If engine oil enters the gap, the annular seal member 600 may swell, break, and coolant may leak. Further, when the annular seal member 600 is bitten, the annular seal member 600 is cut, the cooling water leaks, and the engine oil may enter from the outside to the inside. In this embodiment, this problem can be suppressed.

　バルブ装置１０は、ハウジング開口部２１０と隔壁部６０との間に設けられ、ハウジング開口部２１０と隔壁部６０との間を液密に保持可能な環状シール部材６００をさらに備えている。環状シール部材６００は、例えばゴム等の弾性部材により環状に形成されている。 <2-1-1>
The valve device 10 further includes an annular seal member 600 that is provided between the housing opening 210 and the partition wall 60 and that can hold the space between the housing opening 210 and the partition wall 60 in a liquid-tight manner. The annular seal member 600 is formed in an annular shape by an elastic member such as rubber.
　ハウジング開口部２１０は、内壁が筒状に形成されている。隔壁部６０は、ハウジング開口部２１０の内側に位置し外壁が筒状に形成された隔壁部本体６１を有している。環状シール部材６００は、ハウジング開口部２１０と隔壁部本体６１との間に設けられている。ハウジング開口部２１０の内径と隔壁部本体６１の外径との差は、自由状態の環状シール部材６００の内径と外径との差より小さい。よって、環状シール部材６００は、ハウジング開口部２１０と隔壁部本体６１との間において径方向に圧縮されている。 The housing opening 210 has a cylindrical inner wall. The partition wall 60 includes a partition wall body 61 that is located inside the housing opening 210 and has an outer wall formed in a cylindrical shape. The annular seal member 600 is provided between the housing opening 210 and the partition wall body 61. The difference between the inner diameter of the housing opening 210 and the outer diameter of the partition wall main body 61 is smaller than the difference between the inner diameter and the outer diameter of the annular seal member 600 in the free state. Therefore, the annular seal member 600 is compressed in the radial direction between the housing opening 210 and the partition wall body 61.
　図１１に示すように、ハウジング開口部２１０には、環状の開口段差面６０４、６０５、６０６が形成されている。開口段差面６０４、６０５、６０６は、回転軸Ａｘｒ１方向の内部空間２００側から駆動部７０側へ向かって、この順で形成されている。開口段差面６０４、６０６は、環状の平面状に形成されている。開口段差面６０５は、駆動部７０側から内部空間２００側に向かうに従い回転軸Ａｘｒ１に近付くようテーパ状に形成されている。 As shown in FIG. 11, annular opening step surfaces 604, 605, and 606 are formed in the housing opening 210. The opening step surfaces 604, 605, and 606 are formed in this order from the inner space 200 side in the direction of the rotation axis Axr1 toward the drive unit 70 side. The opening step surfaces 604 and 606 are formed in an annular planar shape. The opening step surface 605 is formed in a tapered shape so as to approach the rotation axis Axr1 from the drive unit 70 side toward the internal space 200 side.
　隔壁部本体６１の外縁部には、環状の隔壁段差面６１１、６１２が形成されている。隔壁段差面６１１は、開口段差面６０４に対向するよう環状の平面状に形成されている。隔壁段差面６１２は、開口段差面６０５、６０６に対向するよう環状の平面状に形成されている。 Annular partition wall step surfaces 611 and 612 are formed on the outer edge of the partition wall body 61. The partition wall step surface 611 is formed in an annular flat shape so as to face the opening step surface 604. The partition step surface 612 is formed in an annular flat shape so as to face the opening step surfaces 605 and 606.
　環状シール部材６００は、開口段差面６０４と隔壁段差面６１１との間に設けられている。 The annular seal member 600 is provided between the opening step surface 604 and the partition wall step surface 611.

　環状シール部材６００は、ハウジング開口部２１０と隔壁部６０との間において径方向に圧縮されている。 <2-2>
The annular seal member 600 is compressed in the radial direction between the housing opening 210 and the partition wall 60.
　そのため、環状シール部材６００によりシャフト３２が調芯され、弁体３１の位置精度、および、後述する回転角センサ８６の検出精度を向上できる。 Therefore, the shaft 32 is aligned by the annular seal member 600, and the positional accuracy of the valve body 31 and the detection accuracy of the rotation angle sensor 86 described later can be improved.
　環状シール部材６００の内周壁の中心と外周壁の中心は一致する。そのため、環状シール部材６００によりシャフト３２を効果的に調芯できる。 The center of the inner peripheral wall of the annular seal member 600 is coincident with the center of the outer peripheral wall. Therefore, the shaft 32 can be effectively aligned by the annular seal member 600.
　また、後述する固定部材８３０の軸方向にかかる力を小さくでき、固定部材８３０の本数を低減できる。 Further, the force applied in the axial direction of the fixing member 830 described later can be reduced, and the number of the fixing members 830 can be reduced.
　水圧がかかると隔壁部本体６１が押し上がる方向に力がかかり、駆動部７０が押し上げられる。この結果、固定部材８３０が押し上がることになる。しかし、本実施形態では、環状シールによって、環状シール部材６００がつっぱっている状態になり、隔壁部本体６１は、摺動抵抗で動きにくくなっている。そのため、固定部材８３０の軸方向にかかる力を小さくできる。 When water pressure is applied, a force is applied in the direction in which the partition wall body 61 is pushed up, and the drive unit 70 is pushed up. As a result, the fixing member 830 is pushed up. However, in the present embodiment, the annular seal member 600 is stuck by the annular seal, and the partition wall body 61 is difficult to move due to sliding resistance. Therefore, the force applied to the fixing member 830 in the axial direction can be reduced.
＜２－２－１＞
　環状シール部材６００の軸方向においてハウジング本体２１との間に軸方向隙間ＳＡｘが形成されている。 <2-2-1>
An axial gap SAx is formed between the annular seal member 600 and the housing body 21 in the axial direction.
　そのため、環状シール部材６００を、ハウジング開口部２１０と隔壁部６０との間において径方向により効果的に圧縮できる。 Therefore, the annular seal member 600 can be effectively compressed in the radial direction between the housing opening 210 and the partition wall 60.
　軸方向隙間ＳＡｘが小さいと、環状シール部材６００が縦長になる。この場合、環状シール部材６００の軸方向に力が発生する。これを防ぐため、環状シール部材６００の径方向のみに力が発生するようにする必要がある。その関係として、本実施形態では、環状シール部材６００の軸を含む平面による断面において、環状シール部材６００の断面積／軸方向隙間ＳＡｘの断面積＜１となるよう設定されている。 When the axial gap SAx is small, the annular seal member 600 becomes vertically long. In this case, a force is generated in the axial direction of the annular seal member 600. In order to prevent this, it is necessary to generate a force only in the radial direction of the annular seal member 600. In relation to this, in the present embodiment, the cross-sectional area of the annular seal member 600 is set such that the cross-sectional area of the annular seal member 600 / the cross-sectional area of the axial clearance SAx <1 in the plane including the axis.

The valve device 10 further includes a fixing member 830 capable of fixing the housing main body 21 and the driving unit cover 80 in a state where the partition wall 60 is sandwiched between the housing main body 21 and the driving unit cover 80.
　そのため、隔壁部６０の位置が安定し、弁体３１の軸精度を向上できる。 Therefore, the position of the partition wall 60 is stabilized, and the axial accuracy of the valve body 31 can be improved.
　本実施形態では、シャフト３２の駆動部７０とは反対側の端部が摺動軸受けとなっている（図３参照）。軸精度が悪くなると摺動抵抗があがる。一方、スプリング３７２によりバルブシール３６を弁体３１に押し付けているが、軸精度が良いと、スプリング３７２によりバルブシール３６を押し付ける力を小さくできる。さらに、軸がずれると、冷却水が弁体３１とバルブシール３６との間で漏れ、暖機が遅くなり、燃費が悪化するおそれがあるが、軸精度が良いと、このような問題を防ぐことができる。 In the present embodiment, the end of the shaft 32 opposite to the drive unit 70 is a sliding bearing (see FIG. 3). If the shaft accuracy deteriorates, the sliding resistance increases. On the other hand, the valve seal 36 is pressed against the valve body 31 by the spring 372. However, if the shaft accuracy is good, the force pressing the valve seal 36 by the spring 372 can be reduced. Furthermore, if the shaft is misaligned, cooling water leaks between the valve body 31 and the valve seal 36, and warming up may be delayed, resulting in a deterioration in fuel consumption. However, if the shaft accuracy is good, such a problem is prevented. be able to.
　また、隔壁部６０および駆動部カバー８０をハウジング本体２１に一度に組み付けでき、組付けを簡素化できる。また、固定部材の数を低減できる。 Also, the partition wall 60 and the drive unit cover 80 can be assembled to the housing body 21 at a time, and the assembly can be simplified. Moreover, the number of fixing members can be reduced.
　固定部材８３０は、例えばねじであり、駆動部カバー８０に形成されたカバー締結穴８３１を通り、ハウジング本体２１の締結穴に螺合する。これにより、駆動部カバー８０は、ハウジング本体２１との間に隔壁部６０を挟んだ状態でハウジング本体２１に固定される。なお、カバー締結穴は、駆動部カバー８０に複数形成され、それぞれに固定部材８３０が挿通されている。なお、駆動部カバー８０の外縁部と隔壁部６０との間には、ゴム製環状のカバーシール部材８０９が設けられている。これにより、駆動部空間８００は気密液密に保持されている。 The fixing member 830 is, for example, a screw, passes through the cover fastening hole 831 formed in the drive unit cover 80, and is screwed into the fastening hole of the housing main body 21. Thus, the drive unit cover 80 is fixed to the housing body 21 with the partition wall 60 sandwiched between the drive body cover 80 and the housing body 21. A plurality of cover fastening holes are formed in the drive unit cover 80, and the fixing member 830 is inserted through each of them. A rubber annular cover seal member 809 is provided between the outer edge portion of the drive unit cover 80 and the partition wall portion 60. Thereby, the drive part space 800 is kept airtight and liquid tight.

　図１１に示すように、隔壁部６０は、シャフト３２の一端を挿通可能なシャフト挿通穴６２を有している。バルブ装置１０は、シャフト挿通穴６２において隔壁部６０にインサート成型された金属環６０１を備えている。金属環６０１は、金属により環状に形成されており、シャフト挿通穴６２と同軸に設けられている。バルブ装置１０は、金属環６０１の内側に設けられ、シャフト３２の一端を軸受けする軸受部６０２を備えている。軸受部６０２は、例えばボールベアリングであり、金属環６０１の内側に圧入されている。 <2-4>
As shown in FIG. 11, the partition wall 60 has a shaft insertion hole 62 through which one end of the shaft 32 can be inserted. The valve device 10 includes a metal ring 601 that is insert-molded in the partition wall 60 in the shaft insertion hole 62. The metal ring 601 is formed of a metal in an annular shape and is provided coaxially with the shaft insertion hole 62. The valve device 10 is provided inside the metal ring 601 and includes a bearing portion 602 that supports one end of the shaft 32. The bearing portion 602 is a ball bearing, for example, and is press-fitted inside the metal ring 601.
　そのため、樹脂（隔壁部６０）と金属（軸受部６０２）との線膨張差や樹脂劣化により、軸受部６０２が保持できなくなるのを抑制でき、シャフト３２の軸受け精度を維持できる。 Therefore, it is possible to prevent the bearing portion 602 from being held due to a difference in linear expansion between the resin (partition wall portion 60) and the metal (bearing portion 602) or the resin deterioration, and the bearing accuracy of the shaft 32 can be maintained.

　図１２に示すように、隔壁部６０は、金属環６０１の径方向外側において駆動部カバー８０側の面６０９から駆動部カバー８０とは反対側へ凹む隔壁凹部６４を有している。ここで、面６０９は、隔壁部６０の駆動部カバー８０側において金属環６０１の駆動部カバー８０側の端面と同一平面上に形成されている平面状の部位である。 <2-5>
As shown in FIG. 12, the partition wall 60 has a partition wall recess 64 that is recessed from the surface 609 on the drive unit cover 80 side to the opposite side of the drive unit cover 80 on the radially outer side of the metal ring 601. Here, the surface 609 is a planar part formed on the same plane as the end surface of the metal ring 601 on the drive unit cover 80 side on the drive unit cover 80 side of the partition wall 60.
　図１１は、「回転軸Ａｘｒ１を含む面」による断面を示す図である。図１２は、「回転軸Ａｘｒ１を含みモータ７１の軸Ａｘｍ１に垂直な面」による断面を示す図である。図１３は、「モータ７１の軸Ａｘｍ１を含み回転軸Ａｘｒ１に平行な面」による断面を示す図である。図１４は、「回転軸Ａｘｒ１を含みモータ７１の軸Ａｘｍ１に平行な面」による断面を示す図である。 FIG. 11 is a view showing a cross section by “a plane including the rotation axis Axr1”. FIG. 12 is a view showing a cross section by “a plane that includes the rotation axis Axr1 and is perpendicular to the axis Axm1 of the motor 71”.

FIG. 14 is a view showing a cross section by “a plane that includes the rotation axis Axr1 and is parallel to the axis Axm1 of the motor 71”.
　そのため、隔壁部６０の一体成型時のヒケや反り、軸受部６０２の圧入による変形を抑制できる。これにより、隔壁部６０の外周部分の寸法精度を向上でき、弁体３１の軸精度を向上できる。 Therefore, sink marks and warpage during integral molding of the partition wall portion 60 and deformation due to press-fitting of the bearing portion 602 can be suppressed. Thereby, the dimensional accuracy of the outer peripheral part of the partition part 60 can be improved, and the axial precision of the valve body 31 can be improved.

　図１２、図１３に示すように、バルブ装置１０は、モータ７１と隔壁部６０との間において圧縮された状態で設けられた弾性部材７４をさらに備えている。弾性部材７４は、例えばゴム等により形成されている。 <2-7>
As shown in FIGS. 12 and 13, the valve device 10 further includes an elastic member 74 provided in a compressed state between the motor 71 and the partition wall 60. The elastic member 74 is made of, for example, rubber.
　そのため、弾性部材７４のダンパ効果により、モータ７１に作用する振動を減衰させることができ、接触不良を抑制するとともに、モータ７１の作動状態を良好に保つことができる。 Therefore, due to the damper effect of the elastic member 74, the vibration acting on the motor 71 can be attenuated, the contact failure can be suppressed, and the operating state of the motor 71 can be kept good.
　モータ７１の振動により、隔壁部６０が動き、摺動抵抗が発生し、燃費が悪化するおそれがある。また、モータ７１の振動で、後述する回転角センサ８６の出力がずれ、燃費が悪化するおそれがある。本実施形態では、弾性部材７４によりモータ７１の振動を抑制することで、上述の問題の発生を抑制できる。 The vibration of the motor 71 causes the partition wall portion 60 to move, causing sliding resistance, which may deteriorate fuel consumption. Further, the vibration of the motor 71 may cause the output of a rotation angle sensor 86 to be described later to shift, resulting in a deterioration in fuel consumption. In the present embodiment, the occurrence of the above-described problem can be suppressed by suppressing the vibration of the motor 71 by the elastic member 74.

　そのため、弾性部材７４によって、内部空間２００側の冷却水の水圧が加わって隔壁部本体６１が浮いてくるのを抑制できる。この結果、冷却水の漏れを防ぎ、当該漏れによる車両１のオーバーヒートを防ぐことができる。 Therefore, the elastic member 74 can prevent the partition wall body 61 from floating due to the water pressure of the cooling water on the internal space 200 side being applied. As a result, leakage of cooling water can be prevented, and overheating of the vehicle 1 due to the leakage can be prevented.

The holding member 73 has a snap fit portion 731 that can be snap-fit coupled to the drive portion cover 80. The holding member 73 is snap-fit coupled to the drive unit cover 80 so as to hold the motor 71, the first gear 721 of the gear unit 72, and the second gear 722 between the drive unit cover 80. Here, the elastic member 74 is provided in a compressed state between the motor main body 710 and the holding member 73.
　上述したように、駆動部７０は、モータ７１の駆動力をシャフト３２に伝達可能なギア部７２を有している。また、バルブ装置１０は、駆動部カバー８０に対しスナップフィット結合可能なスナップフィット部７３１を有し駆動部カバー８０との間にモータ７１およびギア部７２を保持する保持部材７３をさらに備えている。 As described above, the driving unit 70 has the gear unit 72 that can transmit the driving force of the motor 71 to the shaft 32.

　図３に示すように、隔壁部６０には、シャフト挿通穴６２から外側へ延びて隔壁部本体６１の外壁に開口する隔壁貫通穴６５を有している。また、ハウジング２０は、ハウジング開口部２１０の内壁から外側へ延びてハウジング本体２１の外壁に開口し、隔壁貫通穴６５と連通可能に形成されたハウジング貫通穴２７０を有している。 <6-7>
As shown in FIG. 3, the partition wall portion 60 has a partition wall through hole 65 that extends outward from the shaft insertion hole 62 and opens to the outer wall of the partition wall body 61. Further, the housing 20 has a housing through hole 270 that extends outward from the inner wall of the housing opening 210 and opens in the outer wall of the housing body 21 and is formed so as to be able to communicate with the partition wall through hole 65.
　そのため、内部空間２００からシャフト挿通穴６２を通り駆動部７０側へ向かって流れる冷却水を隔壁貫通穴６５へ流すことができる。これにより、内部空間２００の冷却水が駆動部７０側へ流れるのを抑制可能である。なお、隔壁貫通穴６５へ流れた冷却水は、ハウジング貫通穴２７０から外部へ排出される。 Therefore, the cooling water flowing from the internal space 200 through the shaft insertion hole 62 toward the drive unit 70 can flow into the partition wall through hole 65. Thereby, it can suppress that the cooling water of the internal space 200 flows into the drive part 70 side. The cooling water that has flowed into the partition wall through hole 65 is discharged from the housing through hole 270 to the outside.
　本実施形態では、ハウジング貫通穴２７０は、取付面２０１に開口している。つまり、バルブ装置１０がエンジン２に取り付けられると、ハウジング貫通穴２７０は、エンジン２により覆われた状態となる。 In the present embodiment, the housing through hole 270 opens in the mounting surface 201. That is, when the valve device 10 is attached to the engine 2, the housing through hole 270 is covered with the engine 2.
　そのため、ハウジング貫通穴２７０を経由してバルブ装置１０の内部から外部に漏れる冷却水を取付面２０１部分でトラップできる。その結果、冷却水漏れが目立つのを抑制できる。 Therefore, the cooling water leaking from the inside of the valve device 10 to the outside via the housing through hole 270 can be trapped at the mounting surface 201 portion. As a result, it is possible to suppress the conspicuous leakage of cooling water.
＜６－２２＞
　ハウジング貫通穴２７０は、取付面２０１側に開口している。 <6-22>
The housing through hole 270 opens to the mounting surface 201 side.
　そのため、外部の水がハウジング貫通穴２７０、隔壁貫通穴６５を経由してバルブ装置１０の内部に侵入するのを抑制できる。 Therefore, it is possible to suppress external water from entering the inside of the valve device 10 via the housing through hole 270 and the partition wall through hole 65.
　駆動部空間８００に設ける給電端子８５等の金属部材は、メッキがされた部材をプレスで打ち抜いた部分を後メッキする。これにより、冷却水が駆動部空間８００に侵入した場合でも、金属部材の腐食を抑制でき、導通不良を抑制できる。 The metal member such as the power supply terminal 85 provided in the drive unit space 800 is post-plated at a portion obtained by punching the plated member with a press. Thereby, even when a cooling water penetrate | invades into the drive part space 800, corrosion of a metal member can be suppressed and conduction | electrical_connection defect can be suppressed.
　本実施形態のようにエンジン２の冷却水を制御するのに用いられるバルブ装置１０では、冷却水の熱の影響を受ける。したがって、弁体３１の厚さが不均一な肉厚である場合、膨張率が肉厚によって異なるため、弁体３１の全体がゆがむおそれがある。特に本実施形態では、冷却水が流入する入口ポート２２０と弁体３１の内周壁の一部とが対向しているため、弁体３１の内周壁が熱の影響を受けやすい構造にある。 The valve device 10 used for controlling the cooling water of the engine 2 as in this embodiment is affected by the heat of the cooling water. Therefore, when the thickness of the valve body 31 is uneven, the expansion rate varies depending on the thickness, and thus the entire valve body 31 may be distorted. In particular, in this embodiment, since the inlet port 220 into which the cooling water flows and a part of the inner peripheral wall of the valve body 31 face each other, the inner peripheral wall of the valve body 31 is easily affected by heat.
＜３－２７＞
　そこで、図３に示すように、弁体３１は、内周壁のうち少なくとも、冷却水が流入する入口ポート２２０に対向する部分である対向部分３１０が外側へ凹むよう形成されている。より具体的には、弁体３１は、内周壁のうち少なくとも、冷却水が流入する入口ポート２２０に、ボールバルブ４２の弁体開口部４２０を経由して対向する部分である対向部分３１０が外側へ凹むよう形成されている。 <3-27>
Therefore, as shown in FIG. 3, the valve body 31 is formed such that at least a facing portion 310, which is a portion facing the inlet port 220 into which cooling water flows, of the inner peripheral wall is recessed outward. More specifically, the valve body 31 has a facing portion 310 that is a portion facing at least the inlet port 220 into which cooling water flows in the inner peripheral wall via the valve body opening 420 of the ball valve 42. It is formed to be recessed.
　このように、弁体３１の内周壁のうち少なくとも対向部分３１０を凹ませて均肉に近付ければ、弁体３１全体の膨張率が弁体３１の均一に近付くことになるため、弁体３１がゆがむのを防ぐことができる。 In this way, if at least the facing portion 310 of the inner peripheral wall of the valve body 31 is recessed to bring it closer to the uniform thickness, the expansion rate of the entire valve body 31 approaches the valve body 31 uniformly. It can prevent distortion.

　図３に示すように、バルブシール３６は、弁体３１の外周壁のうち少なくとも対向部分３１０に対応する部分に当接する。より具体的には、バルブシール３６は、弁体３１の外周壁のうち、少なくとも対向部分３１０の反対側の部分に当接する。 <3-28>
As shown in FIG. 3, the valve seal 36 contacts at least a portion corresponding to the facing portion 310 of the outer peripheral wall of the valve body 31. More specifically, the valve seal 36 contacts at least a portion of the outer peripheral wall of the valve body 31 opposite to the facing portion 310.
　弁体３１が変形するとバルブシール３６によるシール性が悪化し、暖気性能等が低下するが、本実施形態では、上記構成により、弁体３１の特に対向部分３１０に対応する部分がゆがむのを防ぐことができるため、バルブシール３６によるシール性を確保でき、暖気性能が向上する。 When the valve body 31 is deformed, the sealing performance by the valve seal 36 is deteriorated and the warming performance and the like are deteriorated. However, in the present embodiment, the portion corresponding to the opposed portion 310 of the valve body 31 is prevented from being distorted by the above configuration. Therefore, the sealing performance by the valve seal 36 can be secured, and the warming-up performance is improved.

　ハウジング２０は、複数のポート（２２１～２２３）を有している。ハウジング本体２１がエンジン２に取り付けられた状態において、車両１のヒータ６に接続されるポートである出口ポート２２２は、複数のポートの中で鉛直方向の最も上側に位置しないよう形成されている（図８参照）。 <4-6>
The housing 20 has a plurality of ports (221 to 223). In a state where the housing main body 21 is attached to the engine 2, the outlet port 222 which is a port connected to the heater 6 of the vehicle 1 is formed so as not to be positioned on the uppermost side in the vertical direction among the plurality of ports ( (See FIG. 8).
　そのため、冷却水中の空気がヒータ６に流れるのを抑制でき、車両１の車室内に異音が発生するのを抑制できる。 Therefore, it is possible to suppress the air in the cooling water from flowing to the heater 6 and to suppress the generation of abnormal noise in the vehicle interior of the vehicle 1.

Here, since the 1st control convex part 332 and the 2nd control convex part 342 are formed in the 1st division body 33 and the 2nd division body 34, respectively, the 1st control convex part 332 and the 2nd control convex part When the 342 comes into contact with the restricting portion 631 of the restricting recess 63, the first divided body 33 and the second divided body 34 can be prevented from separating (peeling) at the joint surfaces 331 and 341.
　図２３、２５等に示すように、第１規制凸部３３２、第２規制凸部３４２は、第１最外端面３０１の半径方向の中心に対し径方向外側に位置している。これにより、第１規制凸部３３２、第２規制凸部３４２の周方向の大きさを大きくできるため、第１規制凸部３３２、第２規制凸部３４２の強度を大きくすることができる。 23, 25 etc., the 1st control convex part 332 and the 2nd control convex part 342 are located in the diameter direction outside to the center of the radial direction of the 1st outermost end face 301. As shown in FIG. Thereby, since the magnitude | size of the circumferential direction of the 1st control convex part 332 and the 2nd control convex part 342 can be enlarged, the intensity | strength of the 1st control convex part 332 and the 2nd control convex part 342 can be enlarged.
　図６に示すように、規制部６３１の規制凹部６３の周方向の端面には、規制面６３５、６３６が形成されている。第１規制凸部３３２の弁体３１の周方向の端面には、規制面６３５に当接可能な凸部規制面３３３が形成されている。第２規制凸部３４２の弁体３１の周方向の端面には、規制面６３６に当接可能な凸部規制面３４３が形成されている。弁体３１は、凸部規制面３３３が規制面６３５に当接したとき、または、凸部規制面３４３が規制面６３６に当接したとき、回転が規制される。 As shown in FIG. 6, restriction surfaces 635 and 636 are formed on the circumferential end surface of the restriction recess 63 of the restriction portion 631. A convex portion regulating surface 333 that can contact the regulating surface 635 is formed on the end surface of the first regulating convex portion 332 in the circumferential direction of the valve body 31. A convex portion regulating surface 343 that can contact the regulating surface 636 is formed on the end surface of the second regulating convex portion 342 in the circumferential direction of the valve body 31. The valve body 31 is restricted from rotating when the convex portion regulating surface 333 contacts the regulating surface 635 or when the convex portion regulating surface 343 contacts the regulating surface 636.
　図２３、２５等に示すように、第１規制凸部３３２および第２規制凸部３４２の第１最外端面３０１とは反対側の角部は、第１最外端面３０１に対し傾斜するよう面取りされている。そのため、規制凹部６３の第１規制凸部３３２および第２規制凸部３４２の近傍に砂等の異物があった場合でも、第１規制凸部３３２および第２規制凸部３４２の角部と規制凹部６３との間に異物が噛み込むのを抑制できる。 As shown in FIGS. 23, 25, etc., the corners of the first regulating convex part 332 and the second regulating convex part 342 opposite to the first outermost end face 301 are inclined with respect to the first outermost end face 301. It is chamfered. Therefore, even if there is a foreign substance such as sand in the vicinity of the first restriction convex part 332 and the second restriction convex part 342 of the restriction concave part 63, the corners and the restriction of the first restriction convex part 332 and the second restriction convex part 342 are restricted. It can suppress that a foreign material bites into between the recessed parts 63.

　第１規制凸部３３２は、接合面３３１に沿って規制凹部６３側へ延びている。第２規制凸部３４２は、第１規制凸部３３２に当接しつつ、接合面３３１に沿って規制凹部６３側へ延びている。 <3-8>
The first restriction convex part 332 extends toward the restriction concave part 63 along the joint surface 331. The second restriction convex portion 342 extends toward the restriction concave portion 63 along the joint surface 331 while being in contact with the first restriction convex portion 332.
　そのため、第１規制凸部３３２、第２規制凸部３４２が規制凹部６３の規制部６３１に当接したとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れるのをより効果的に抑制できる。 Therefore, when the first restriction convex part 332 and the second restriction convex part 342 come into contact with the restriction part 631 of the restriction concave part 63, the first divided body 33 and the second divided body 34 are separated by the joint surfaces 331 and 341.

The valve body 31 has valve body opening ribs 431 and 432 that connect the inner edge ends of the valve body opening 430. Therefore, the strength of the valve body openings 410, 420, and 430 can be improved.
　弁体開口リブ４１１、４２１、４３１は、シャフト３２の軸Ａｘｓ１（回転軸Ａｘｒ１）を含む仮想平面、すなわち、接合面３３１、３４１を含む仮想平面Ｖｐ１上に形成されている。つまり、弁体開口リブ４１１、４２１、４３１は、接合面３３１、３４１を挟むようにして形成されている。弁体開口リブ４２２、４３２は、シャフト３２の軸Ａｘｓ１（回転軸Ａｘｒ１）を含み仮想平面Ｖｐ１に直交する仮想平面上に形成されている。 The valve body opening ribs 411, 421, 431 are formed on a virtual plane including the axis Axs1 (rotation axis Axr1) of the shaft 32, that is, a virtual plane Vp1 including the joint surfaces 331, 341. That is, the valve body opening ribs 411, 421, 431 are formed so as to sandwich the joint surfaces 331, 341. The valve body opening ribs 422 and 432 are formed on a virtual plane that includes the axis Axs1 (rotation axis Axr1) of the shaft 32 and is orthogonal to the virtual plane Vp1.
　図２４、図２５に示すように、弁体開口リブ４１１は、弁体３１のボールバルブ４１の外周壁に沿う仮想球面Ｖｓ１から径方向内側へ離れた位置に形成されている。 24 and 25, the valve body opening rib 411 is formed at a position away from the virtual spherical surface Vs1 along the outer peripheral wall of the ball valve 41 of the valve body 31 inward in the radial direction.
　仮想球面Ｖｓ１は、ボールバルブ４１の外周壁を含む仮想的な球面である。 The virtual spherical surface Vs1 is a virtual spherical surface including the outer peripheral wall of the ball valve 41.
　そのため、弁体３１の回転時、バルブシール３６が弁体開口リブ４１１に引っ掛かり摺動抵抗が増大するのを抑制できる。 Therefore, when the valve body 31 is rotated, it is possible to suppress the valve seal 36 from being caught by the valve body opening rib 411 and increasing the sliding resistance.
＜３－９－１＞
　図２４、図２５に示すように、弁体開口リブ４１１は、仮想球面Ｖｓ１から所定の距離を空けて円弧状に形成されている。なお、弁体開口リブ４２１、４２２、および、弁体開口リブ４３１、４３２についても、ボールバルブ４２、４３の外周壁に沿う仮想球面から所定の距離を空けて円弧状に形成されている。 <3-9-1>
As shown in FIGS. 24 and 25, the valve body opening rib 411 is formed in an arc shape with a predetermined distance from the phantom spherical surface Vs1. The valve body opening ribs 421 and 422 and the valve body opening ribs 431 and 432 are also formed in an arc shape with a predetermined distance from a virtual spherical surface along the outer peripheral wall of the ball valves 42 and 43.
　そのため、弁体３１の回転時の摺動抵抗の増大を抑制できるとともに、弁体開口リブ４１１、４２１、４２２、４３１、４３２の内側の流路面積を大きくできる。 Therefore, an increase in sliding resistance during rotation of the valve body 31 can be suppressed, and the flow path area inside the valve body opening ribs 411, 421, 422, 431, and 432 can be increased.
　図２４に示すように、弁体開口リブ４１１は、円弧状の平板状に形成されている。弁体開口リブ４１１の径方向外側の部位であるリブ外縁部４０１は、仮想球面Ｖｓ１からの距離が一定である。弁体開口リブ４１１の径方向内側の部位であるリブ内縁部４０２は、仮想球面Ｖｓ１からの距離が一定である。弁体開口リブ４１１の一方の端部であるリブ端部４０３は、弁体開口部４１０の内縁端のうち筒状接続部４４とは反対側の部位に接続している。弁体開口リブ４１１の他方の端部であるリブ端部４０４は、弁体開口部４１０の内縁端のうち筒状接続部４４側の部位に接続している。 As shown in FIG. 24, the valve element opening rib 411 is formed in an arc-shaped flat plate shape. The rib outer edge 401, which is the radially outer portion of the valve body opening rib 411, has a constant distance from the phantom spherical surface Vs1. The rib inner edge 402, which is the radially inner portion of the valve body opening rib 411, has a constant distance from the phantom spherical surface Vs1. A rib end 403, which is one end of the valve body opening rib 411, is connected to a portion of the inner edge of the valve body opening 410 that is opposite to the cylindrical connection portion 44. The rib end portion 404 which is the other end portion of the valve body opening rib 411 is connected to a portion of the inner edge end of the valve body opening portion 410 on the cylindrical connection portion 44 side.

　そのため、弁体３１の接合面３３１、３４１において外周壁に形成され得る段差により、弁体３１が全閉状態のとき、バルブシール３６と弁体３１の外周壁との間から冷却水が漏れるのを抑制できる。 Therefore, cooling water leaks between the valve seal 36 and the outer peripheral wall of the valve body 31 when the valve body 31 is in the fully closed state due to the steps that can be formed on the outer peripheral wall at the joint surfaces 331 and 341 of the valve body 31.

As shown in FIG. 20, the valve body 31 has a specific shape portion 441 that is formed on the joint surfaces 331 and 341 in the cylindrical connection portion 44 and has an outer wall having a curvature different from the curvature of the outer peripheral wall of the cylindrical connection portion 44. doing. The valve body 31 has a specific shape portion 451 having an outer wall that is formed on the joint surfaces 331 and 341 in the tubular valve connection portion 45 and has a curvature different from the curvature of the outer peripheral wall of the tubular valve connection portion 45.
　そのため、弁体３１の回転時、特定形状部４４１、４５１とバルブシール３６とが摺動することはなく、弁体３１の作動不良を抑制できるとともに、バルブシール３６の摩耗を抑制できる。 Therefore, when the valve body 31 rotates, the specific shape portions 441 and 451 and the valve seal 36 do not slide, so that the malfunction of the valve body 31 can be suppressed and the wear of the valve seal 36 can be suppressed.

The length of the specific shape portion 451 in the axis Axs1 direction of the shaft 32 is about 1/3 of the length of the tubular valve connection portion 45. Therefore, the enlargement of the valve body 31 can be suppressed.

As shown in FIG. 22, the valve body 31 includes an inter-valve space 400 formed between the ball valve 41 and the ball valve 42 on the radially outer side of the cylindrical connection portion 44 and a valve body flow path 300 of the ball valve 41. Of the ball valve 42 so as to connect the end surface opening 415 formed on the end surface of the ball valve 41 in the direction of the rotation axis Axr1 and the inter-valve space 400 and the valve body flow passage 300 of the ball valve 42. It has an end face opening 425 formed on the end face in the direction of the axis Axr1. Here, the end surface openings 415 and 425 correspond to a “first end surface opening” and a “second end surface opening”, respectively.
　入口ポート２２０は（図３参照）、バルブ間空間４００に連通している。そのため、入口ポート２２０から内部空間２００に流入した冷却水は、バルブ間空間４００、端面開口部４１５、４２５を経由して弁体内流路３００に流入可能である。 The inlet port 220 (see FIG. 3) communicates with the inter-valve space 400. Therefore, the cooling water flowing into the internal space 200 from the inlet port 220 can flow into the valve body flow path 300 via the inter-valve space 400 and the end surface openings 415 and 425.
　バルブ間空間４００は、周方向の全域にわたって開口している。そのため、入口ポート２２０から内部空間２００に流入し弁体内流路３００に向かう冷却水の通水抵抗を小さくできる。 The inter-valve space 400 is open over the entire circumferential direction. Therefore, the flow resistance of the cooling water flowing from the inlet port 220 into the internal space 200 and flowing toward the valve body flow path 300 can be reduced.
　図９に示すように、バルブ間空間４００は、回転軸Ａｘｒ１方向において、入口ポート２２０およびリリーフポート２２４と重なっている。そのため、入口ポート２２０から流入した冷却水がリリーフポート２２４へ流れやすくなり、リリーフ弁３９の反応性を向上できる。 As shown in FIG. 9, the inter-valve space 400 overlaps the inlet port 220 and the relief port 224 in the direction of the rotation axis Axr1. Therefore, the cooling water flowing from the inlet port 220 can easily flow to the relief port 224, and the reactivity of the relief valve 39 can be improved.
　図２０に示すように、バルブ間空間４００は、弁体３１の軸方向の第１最外端面３０１から第２最外端面３０２までの部位のうち最も外径が小さい部分である筒状接続部４４の径方向外側に形成されている。また、バルブ間空間４００の外径は、端面開口部４１５、４２５の径方向外側の径よりも小さい。 As shown in FIG. 20, the inter-valve space 400 is a cylindrical connecting portion that is a portion having the smallest outer diameter among the portions from the first outermost end surface 301 to the second outermost end surface 302 in the axial direction of the valve body 31. 44 is formed radially outward. The outer diameter of the inter-valve space 400 is smaller than the diameter of the end surface openings 415 and 425 on the outer side in the radial direction.

　図２７に示すように、シャフト３２は、筒状接続部４４においてインサート成型により弁体３１と一体に形成されている。つまり、シャフト３２は、筒状接続部４４には溶着されているが、弁体３１の筒状接続部４４以外の部位には溶着されていない。 <3-14>
As shown in FIG. 27, the shaft 32 is formed integrally with the valve body 31 by insert molding at the cylindrical connecting portion 44. That is, the shaft 32 is welded to the cylindrical connection portion 44, but is not welded to a portion other than the cylindrical connection portion 44 of the valve body 31.
　弁体内流路３００にシャフト３２とのインサート成型部を設けた場合、弁体内流路３００の流路面積が小さくなり通水抵抗が大きくなるおそれがあるが、本実施形態では、弁体内流路３００の外の筒状接続部４４にシャフト３２とのインサート成型部が設けられているため、通水抵抗を小さくできる。 When an insert molding portion with the shaft 32 is provided in the valve body flow path 300, the flow path area of the valve body flow path 300 may be reduced and the water flow resistance may be increased. Since the insert molding part with the shaft 32 is provided in the cylindrical connection part 44 outside 300, the water flow resistance can be reduced.

　図２７に示すように、シャフト３２は、筒状接続部４４との相対回転を規制可能な回り止め部３２１を有している。回り止め部３２１は、断面形状が多角形となるよう形成されている。本実施形態では、断面形状が六角形となるよう形成されている。ここで、回り止め部３２１は、例えば円柱状のシャフト３２の外周壁を周方向に６箇所、平面状に切削等することにより形成されている。そのため、回り止め部３２１の外壁は、シャフト３２の外周壁に対し径方向内側に位置している。なお、筒状接続部４４の内壁は、回り止め部３２１の形状に対応するよう断面形状が六角形となるよう形成されている。 <3-15>
As shown in FIG. 27, the shaft 32 has a detent portion 321 that can restrict relative rotation with the cylindrical connection portion 44. The anti-rotation part 321 is formed so that the cross-sectional shape is a polygon. In this embodiment, the cross-sectional shape is a hexagon. Here, the rotation prevention part 321 is formed, for example, by cutting the outer peripheral wall of the columnar shaft 32 into a flat shape at six places in the circumferential direction. Therefore, the outer wall of the rotation preventing portion 321 is located on the radially inner side with respect to the outer peripheral wall of the shaft 32. Note that the inner wall of the cylindrical connection portion 44 is formed to have a hexagonal cross section so as to correspond to the shape of the rotation preventing portion 321.
　そのため、簡単な構成で、弁体３１とシャフト３２との相対回転を規制できる。 Therefore, the relative rotation between the valve body 31 and the shaft 32 can be restricted with a simple configuration.

　筒状バルブ接続部４５は、外周壁および内周壁が筒状に形成されている。そのため、内側の弁体内流路３００の流路面積を確保できる。 The cylindrical valve connecting portion 45 has an outer peripheral wall and an inner peripheral wall formed in a cylindrical shape. Therefore, the flow path area of the inner valve body flow path 300 can be secured.

　図２０に示すように、ボールバルブ４１の外周壁の外径は、ボールバルブ４３の外周壁の外径と同じである。なお、ボールバルブ４２の外周壁の外径も、ボールバルブ４１の外周壁の外径、ボールバルブ４３の外周壁の外径と同じである。 <3-17>
As shown in FIG. 20, the outer diameter of the outer peripheral wall of the ball valve 41 is the same as the outer diameter of the outer peripheral wall of the ball valve 43. The outer diameter of the outer peripheral wall of the ball valve 42 is also the same as the outer diameter of the outer peripheral wall of the ball valve 41 and the outer diameter of the outer peripheral wall of the ball valve 43.
　ボールバルブ４１の回転軸Ａｘｒ１方向のボールバルブ４３とは反対側の端面である第１最外端面３０１の面積は、ボールバルブ４３の回転軸Ａｘｒ１方向のボールバルブ４１とは反対側の端面である第２最外端面３０２の面積と異なる。ここで、第２最外端面３０２の面積は、第１最外端面３０１の面積より大きい。よって、回転軸Ａｘｒ１方向におけるボールバルブ４３の長さは、ボールバルブ４１の長さより短い。 The area of the first outermost end surface 301 that is the end surface of the ball valve 41 opposite to the ball valve 43 in the direction of the rotation axis Axr1 is the end surface of the ball valve 43 opposite to the ball valve 41 in the direction of the rotation axis Axr1. It is different from the area of the second outermost end surface 302. Here, the area of the second outermost end surface 302 is larger than the area of the first outermost end surface 301. Therefore, the length of the ball valve 43 in the direction of the rotation axis Axr1 is shorter than the length of the ball valve 41.
　そのため、弁体３１の軸方向の大きさを小さくでき、バルブ装置１０の体格を小さくできる。 Therefore, the size of the valve body 31 in the axial direction can be reduced, and the physique of the valve device 10 can be reduced.

The valve body opening rib 432 is connected. Here, the valve body opening rib 422 and the valve body opening rib 432 correspond to a “second valve body opening rib” and a “third valve body opening rib”, respectively.
　弁体開口リブ４２２と弁体開口リブ４３２とは、弁体３１の周方向において同じ位置に形成されている。つまり、弁体開口リブ４２２、４３２は、回転軸Ａｘｒ１と平行な方向に並ぶよう形成されている。なお、弁体開口リブ４１１と弁体開口リブ４２１とは、弁体３１の周方向において同じ位置に形成されている。 The valve element opening rib 422 and the valve element opening rib 432 are formed at the same position in the circumferential direction of the valve element 31. That is, the valve body opening ribs 422 and 432 are formed to be aligned in a direction parallel to the rotation axis Axr1. The valve body opening rib 411 and the valve body opening rib 421 are formed at the same position in the circumferential direction of the valve body 31.
　そのため、弁体開口リブ４２２、４３２の周囲を流れる冷却水の乱れを抑制でき、通水抵抗を低減できる。 Therefore, the disturbance of the cooling water flowing around the valve body opening ribs 422 and 432 can be suppressed, and the water flow resistance can be reduced.

Two end face opening ribs 417 and 427 are formed so that the cylindrical connecting portion 44 is sandwiched therebetween.
　なお、端面開口リブ４１６、４２６は、仮想平面Ｖｐ１上に形成されている。つまり、端面開口リブ４１６、４２６は、接合面３３１、３４１を挟むようにして形成されている。よって、弁体開口リブ４１１、４２１、および、端面開口リブ４１６、４２６は、弁体３１の周方向において同じ位置に形成されている。 Note that the end face opening ribs 416 and 426 are formed on the virtual plane Vp1.

Visually visible.
　そのため、端面開口部４１５、４２５における通水抵抗を低減できる。 Therefore, it is possible to reduce the water flow resistance in the end surface openings 415 and 425.

In the primary molding step, the first divided body 33 and the second divided body 34 are resin-molded by the first mold 110 and the second mold 120, respectively. Specifically, as shown in FIG. 29A, the first outer mold 111 and the first inner mold 112 are brought into contact with each other, the second outer mold 121 and the second inner mold 122 are brought into contact with each other, A molten resin is injected between the first concave surface 113 and the first convex surface 114 and between the second concave surface 123 and the second convex surface 171.

When the first divided body 33 and the second divided body 34 are cooled and hardened, the primary molding process is completed.
＜３－２２－１＞
　１次成形工程において第１分割体３３と第２分割体３４とを樹脂成形するとき、回転軸Ａｘｒ１方向および周方向の少なくとも一部の範囲において、第１凹面１１３と第１凸面１１４との距離、ならびに、第２凹面１２３と第２凸面１２４との距離は同じである。 <3-22-1>

　第２成形工程では、第１分割体３３の接合面３３１における溶着部（３１１、３１２、３１３）と第２分割体３４の接合面３４１における溶着部（３１１、３１２、３１３）との間に樹脂を射出し、第１分割体３３と第２分割体３４とを溶着する。 In the second molding step, a resin is formed between the welded portions (311, 312, 313) on the joint surface 331 of the first divided body 33 and the welded portions (311, 312, 313) on the joint surface 341 of the second divided body 34. The first divided body 33 and the second divided body 34 are welded.
　上記製造方法でバルブ３０を製造することにより、弁体３１の外周壁の球面の成形精度を向上できる。これにより、弁体３１の外周壁における冷却水の漏れを抑制可能である。 By manufacturing the valve 30 by the above manufacturing method, the molding accuracy of the spherical surface of the outer peripheral wall of the valve body 31 can be improved. Thereby, the leakage of the cooling water in the outer peripheral wall of the valve body 31 can be suppressed.
　また、弁体内流路３００の流路面積を大きくでき、通水抵抗を小さくできる。 Moreover, the flow passage area of the valve body flow passage 300 can be increased, and the water flow resistance can be reduced.
　上述のように、本実施形態では、ダイスライドインジェクション（ＤＳＩ）によりバルブ３０を製造する。ＤＳＩ成型では、弁体３１が２つに分離している。そのため、弁体３１の軸方向で型抜きする通常の製造方法の場合と比べ、型の抜き方向を増やすことなく弁体３１の開口数等を変更できる。この結果、複雑なフローダイアグラムに対応できる。なお、弁体３１が一体に形成される場合、開口数が増えると、抜く型の数が増える。 As described above, in this embodiment, the valve 30 is manufactured by die slide injection (DSI). In DSI molding, the valve body 31 is separated into two. Therefore, the numerical aperture of the valve body 31 can be changed without increasing the mold drawing direction, compared to the case of the normal manufacturing method in which the mold is cut in the axial direction of the valve body 31. As a result, complex flow diagrams can be handled. In addition, when the valve body 31 is integrally formed, the number of dies to be removed increases as the numerical aperture increases.
　ＤＳＩ成型では、型を抜く方向が弁体３１の径方向であるため、弁体３１の軸方向で型抜きする通常の製造方法の場合と比べ、型が製品の表面に擦れることにより変改してしまうのを防ぐことができる。加えて、製品の表面の変形を防ぐことができるため、シール性の向上にもつながる。 In the DSI molding, since the direction in which the mold is pulled out is the radial direction of the valve body 31, compared with the case of the normal manufacturing method in which the mold is punched in the axial direction of the valve body 31, the mold is rubbed against the surface of the product. Can be prevented. In addition, since the deformation of the product surface can be prevented, the sealing performance is improved.

The valve body opening ribs 421 and 422 and the valve body opening ribs 431 and 432 are also formed in a straight line with a predetermined distance from a virtual spherical surface along the outer peripheral wall of the ball valves 42 and 43.
　そのため、弁体３１の回転時、バルブシール３６が弁体開口リブ４１１に引っ掛かり摺動抵抗が増大するのをより効果的に抑制できる。 Therefore, when the valve body 31 rotates, it is possible to more effectively suppress the valve seal 36 from being caught by the valve body opening rib 411 and increasing the sliding resistance.
　図３３に示すように、弁体開口リブ４１１は、直線状の平板状に形成されている。弁体開口リブ４１１の径方向外側の部位であるリブ外縁部４０１は、回転軸Ａｘｒ１に対し平行となるよう直線状に形成され、仮想球面Ｖｓ１からの距離が回転軸Ａｘｒ１方向において変化する。弁体開口リブ４１１の径方向内側の部位であるリブ内縁部４０２は、回転軸Ａｘｒ１に対し平行となるよう直線状に形成され、仮想球面Ｖｓ１からの距離が回転軸Ａｘｒ１方向において変化する。弁体開口リブ４１１の一方の端部であるリブ端部４０３は、弁体開口部４１０の内縁端のうち筒状接続部４４とは反対側の部位に接続している。弁体開口リブ４１１の他方の端部であるリブ端部４０４は、弁体開口部４１０の内縁端のうち筒状接続部４４側の部位に接続している。 33, the valve element opening rib 411 is formed in a linear flat plate shape. The rib outer edge 401, which is the radially outer portion of the valve body opening rib 411, is formed in a straight line so as to be parallel to the rotation axis Axr1, and the distance from the phantom spherical surface Vs1 changes in the direction of the rotation axis Axr1. The rib inner edge portion 402, which is the radially inner portion of the valve body opening rib 411, is formed in a straight line so as to be parallel to the rotation axis Axr1, and the distance from the phantom spherical surface Vs1 changes in the direction of the rotation axis Axr1. A rib end 403, which is one end of the valve body opening rib 411, is connected to a portion of the inner edge of the valve body opening 410 that is opposite to the cylindrical connection portion 44. The rib end portion 404 which is the other end portion of the valve body opening rib 411 is connected to a portion of the inner edge end of the valve body opening portion 410 on the cylindrical connection portion 44 side.
　図３３に示すように、弁体開口リブ４１１は、第２規制凸部３４２に対しボールバルブ４１の径方向外側に位置している。 33, the valve body opening rib 411 is located on the radially outer side of the ball valve 41 with respect to the second restricting convex portion 342. As shown in FIG.

The shaft 32 is provided on the rotation axis Axr1 of the valve body 31. The ball valve 46 has an outer peripheral wall 461 and an inner peripheral wall 462. The outer peripheral wall 461 is formed in a spherical shape so as to swell outward in the radial direction of the ball valve 46. The inner peripheral wall 462 is formed in a spherical shape so as to be recessed outward in the radial direction of the ball valve 46. Here, the valve body 31 has the same distance between the outer peripheral wall 461 and the inner peripheral wall 462 in at least a partial range in the direction of the rotation axis Axr1 and the circumferential direction.

　次に、バルブ３０の製造方法について説明する。 Next, a method for manufacturing the valve 30 will be described.
　図３５に示すように、型装置１５０は、上ベース１５１、下ベース１５２、上支持柱１５３、下支持柱１５４、型駆動体１５５、第１内側型１６０、第２内側型１７０、外側型１８０等を備えている。 As shown in FIG. 35, the mold apparatus 150 includes an upper base 151, a lower base 152, an upper support pillar 153, a lower support pillar 154, a mold driver 155, a first inner mold 160, a second inner mold 170, and an outer mold 180. Etc.
　上ベース１５１は、板状に形成されている。下ベース１５２は、板状に形成され、上ベース１５１に対し平行となるよう設けられている。上支持柱１５３は、棒状に形成され、一端が上ベース１５１の下ベース１５２とは反対側に接続している。上支持柱１５３は、一端が上ベース１５１において型装置１５０の中心軸ＣＡｘ１周りに環状をなすよう８本設けられている（図３６参照）。上支持柱１５３は、一端を支点として他端側が中心軸ＣＡｘ１側へ揺動可能である。 The upper base 151 is formed in a plate shape. The lower base 152 is formed in a plate shape and is provided so as to be parallel to the upper base 151. The upper support pillar 153 is formed in a rod shape, and one end thereof is connected to the side opposite to the lower base 152 of the upper base 151. Eight upper support columns 153 are provided so that one end of the upper support column 153 has an annular shape around the central axis CAx1 of the mold apparatus 150 in the upper base 151 (see FIG. 36).

　下支持柱１５４は、棒状に形成され、一端が下ベース１５２の上ベース１５１側に接続している。下支持柱１５４は、他端が上ベース１５１の穴を通り上ベース１５１に対し下ベース１５２とは反対側に位置するよう設けられている。下支持柱１５４は、一端が下ベース１５２において中心軸ＣＡｘ１周りに環状をなすよう８本設けられている（図３７参照）。下支持柱１５４は、一端を支点として他端側が中心軸ＣＡｘ１側へ揺動可能である。 The lower support pillar 154 is formed in a rod shape, and one end thereof is connected to the upper base 151 side of the lower base 152. The lower support column 154 is provided so that the other end passes through the hole of the upper base 151 and is located on the opposite side of the lower base 152 with respect to the upper base 151. Eight lower support pillars 154 are provided so that one end forms a ring around the central axis CAx1 in the lower base 152 (see FIG. 37). The lower support column 154 is swingable toward the central axis CAx1 at the other end with one end as a fulcrum.
　第１内側型１６０は、８本の上支持柱１５３のそれぞれの他端に設けられている。すなわち、第１内側型１６０は、合計８個設けられている。第２内側型１７０は、８本の下支持柱１５４のそれぞれの他端に設けられている。すなわち、第２内側型１７０は、合計８個設けられている。 The first inner mold 160 is provided at the other end of each of the eight upper support columns 153. That is, a total of eight first inner molds 160 are provided. The second inner mold 170 is provided at the other end of each of the eight lower support columns 154. That is, a total of eight second inner molds 170 are provided.
　図３８に示すように、第１内側型１６０は、外壁の一部に第１凸面１６１を有している。第１凸面１６１は、球面状に形成されている。第２内側型１７０は、外壁の一部に第２凸面１７１を有している。第２凸面１７１は、球面状に形成されている。 38, the first inner mold 160 has a first convex surface 161 on a part of the outer wall. The first convex surface 161 is formed in a spherical shape. The second inner mold 170 has a second convex surface 171 on a part of the outer wall. The second convex surface 171 is formed in a spherical shape.
　図３５に示すように、第１内側型１６０と第２内側型１７０とは、第１凸面１６１、第２凸面１７１が中心軸ＣＡｘ１とは反対側を向くよう周方向に交互に配置されている。これにより、第１凸面１６１と第２凸面１７１とは、周方向に連続する球面を形成可能である。 As shown in FIG. 35, the first inner mold 160 and the second inner mold 170 are alternately arranged in the circumferential direction so that the first convex surface 161 and the second convex surface 171 face the side opposite to the central axis CAx1. . Thereby, the 1st convex surface 161 and the 2nd convex surface 171 can form the spherical surface continuous in the circumferential direction.
　外側型１８０は、内壁に凹面１８１を有している（図３９参照）。凹面１８１は、球面状に形成されている。外側型１８０は、凹面１８１が第１凸面１６１および第２凸面１７１に対向するよう第１内側型１６０および第２内側型１７０の外側に配置される。 The outer mold 180 has a concave surface 181 on the inner wall (see FIG. 39). The concave surface 181 is formed in a spherical shape. The outer mold 180 is disposed outside the first inner mold 160 and the second inner mold 170 so that the concave surface 181 faces the first convex surface 161 and the second convex surface 171.
　型駆動体１５５は、筒状に形成されている。型駆動体１５５は、中心軸ＣＡｘ１と同軸に第１内側型１６０および第２内側型１７０の内側に配置される。型駆動体１５５の外周壁には、係合溝部１５６が形成されている。係合溝部１５６は、型駆動体１５５の一端から他端へ延びるよう形成されている。係合溝部１５６は、型駆動体１５５の周方向に等間隔で８つ形成されている。 The mold driver 155 is formed in a cylindrical shape. The mold driver 155 is disposed inside the first inner mold 160 and the second inner mold 170 coaxially with the central axis CAx1. An engagement groove 156 is formed on the outer peripheral wall of the mold driver 155. The engaging groove 156 is formed so as to extend from one end to the other end of the mold driver 155. Eight engaging groove portions 156 are formed at equal intervals in the circumferential direction of the mold driver 155.
　第１内側型１６０は、第１凸面１６１とは反対側に係合凸部１６２を有している。係合凸部１６２は、型駆動体１５５の係合溝部１５６に係合可能である。また、型駆動体１５５は、係合溝部１５６に係合凸部１６２が係合した状態で、中心軸ＣＡｘ１方向に移動可能である。型駆動体１５５の外周壁は、テーパ状に形成されている。そのため、型駆動体１５５が第１内側型１６０および第２内側型１７０に対し中心軸ＣＡｘ１方向の上ベース１５１側へ相対移動すると、８個の第１内側型１６０は、中心軸ＣＡｘ１側へ集まるようにして移動する（図３９、図４０参照）。これにより、第１凸面１６１で形成される球状の面の内径が縮小する。なお、第１内側型１６０が中心軸ＣＡｘ１側へ集まるようにして移動すると、８個の第２内側型１７０も中心軸ＣＡｘ１側へ集まるようにして移動可能である。すなわち、第１内側型１６０と第２内側型１７０とが中心軸ＣＡｘ１側へ集まるようにして移動すると、第１凸面１６１および第２凸面１７１で形成される球状の面の内径が縮小する。 The first inner mold 160 has an engaging convex portion 162 on the side opposite to the first convex surface 161. The engaging convex portion 162 can be engaged with the engaging groove portion 156 of the mold driver 155. The mold driver 155 is movable in the direction of the central axis CAx1 in a state in which the engagement protrusion 162 is engaged with the engagement groove 156. The outer peripheral wall of the mold driver 155 is formed in a tapered shape. Therefore, when the mold driver 155 moves relative to the first inner mold 160 and the second inner mold 170 toward the upper base 151 in the direction of the central axis CAx1, the eight first inner molds 160 gather toward the central axis CAx1. In this way, it moves (see FIGS. 39 and 40). As a result, the inner diameter of the spherical surface formed by the first convex surface 161 is reduced. When the first inner mold 160 moves so as to gather toward the central axis CAx1, the eight second inner molds 170 can also move so as to gather toward the central axis CAx1. That is, when the first inner mold 160 and the second inner mold 170 move so as to gather toward the central axis CAx1, the inner diameter of the spherical surface formed by the first convex surface 161 and the second convex surface 171 is reduced.
　バルブ３０の製造方法は、以下の工程を含む。 The manufacturing method of the valve 30 includes the following steps.
＜３－２５＞球面状弁体製造方法
　（樹脂成形工程）
　樹脂成形工程では、外側型１８０と外側型１８０の内側に配置される第１内側型１６０および第２内側型１７０との間において弁体３１を樹脂成形する。具体的には、図３５、図３９の（Ａ）に示すように、第１凸面１６１および第２凸面１７１で形成される球状の面と外側型１８０の凹面１８１との間に形成される空間に、溶融した樹脂を射出する。当該樹脂が冷え固まると、樹脂成形工程が完了する。 <3-25> Spherical valve body manufacturing method (resin molding process)
In the resin molding step, the valve body 31 is resin-molded between the outer mold 180 and the first inner mold 160 and the second inner mold 170 disposed inside the outer mold 180. Specifically, as shown in FIGS. 35 and 39A, a space formed between the spherical surface formed by the first convex surface 161 and the second convex surface 171 and the concave surface 181 of the outer die 180. Then, the molten resin is injected. When the resin cools and hardens, the resin molding process is completed.
＜３－２５－１＞
　樹脂成形工程において弁体３１を樹脂成形するとき、回転軸Ａｘｒ１方向および周方向の少なくとも一部の範囲において、凹面１８１と第１凸面１６１および第２凸面１７１との距離が同じである（図３９の（Ａ）参照）。 <3-25-1>
When the valve body 31 is resin-molded in the resin molding step, the distance between the concave surface 181 and the first convex surface 161 and the second convex surface 171 is the same in at least a part of the rotational axis Axr1 direction and the circumferential direction (FIG. 39). (See (A)).
　そのため、弁体３１の少なくとも一部を均肉にすることができる。これにより、弁体３１の外周壁の球面の精度をより向上でき、弁体内流路３００の流路面積をより大きくできる。 Therefore, at least a part of the valve body 31 can be made uniform. Thereby, the precision of the spherical surface of the outer peripheral wall of the valve body 31 can be further improved, and the flow passage area of the flow passage 300 can be increased.
　（型移動工程）
　樹脂成形工程の後の型移動工程では、第１内側型１６０および第２内側型１７０を弁体３１の内側へ移動させる。具体的には、図３９の（Ａ）、（Ｂ）、図４０の（Ａ）～（Ｅ）に示すように、第１内側型１６０および第２内側型１７０に対し型駆動体１５５を中心軸ＣＡｘ１方向へ相対移動させ、第１内側型１６０および第２内側型１７０を中心軸ＣＡｘ１側へ移動させ、第１凸面１６１および第２凸面１７１により形成される球状の面を縮径させる。これにより、弁体３１の内周壁４６２と第１凸面１６１および第２凸面１７１との間に隙間が形成される。そして、弁体３１に対し第１内側型１６０および第２内側型１７０を中心軸ＣＡｘ１方向に相対移動させることで、第１内側型１６０および第２内側型１７０を弁体３１内から抜き出す。 (Mold transfer process)
In the mold moving process after the resin molding process, the first inner mold 160 and the second inner mold 170 are moved to the inside of the valve body 31. Specifically, as shown in FIGS. 39A and 39B and FIGS. 40A to 40E, the mold driver 155 is centered with respect to the first inner mold 160 and the second inner mold 170. The first inner mold 160 and the second inner mold 170 are moved relative to each other in the direction of the axis CAx1, and the first inner mold 160 and the second inner mold 170 are moved toward the central axis CAx1, thereby reducing the diameter of the spherical surface formed by the first convex surface 161 and the second convex surface 171. Thereby, a gap is formed between the inner peripheral wall 462 of the valve body 31 and the first and second convex surfaces 161 and 171. Then, the first inner mold 160 and the second inner mold 170 are extracted from the valve body 31 by moving the first inner mold 160 and the second inner mold 170 relative to the valve body 31 in the direction of the central axis CAx1.
＜３－２６＞
　図４１の（Ａ）、（Ｂ）に示すように、第１凸面１６１および第２凸面１７１の突出高さＨ１は、型移動工程において第１内側型１６０および第２内側型１７０が移動可能な距離Ｄｍ１より小さく設定されている。 <3-26>
As shown in FIGS. 41A and 41B, the protrusion height H1 of the first convex surface 161 and the second convex surface 171 is such that the first inner die 160 and the second inner die 170 can move in the die moving step. It is set smaller than the distance Dm1.
　そのため、第１内側型１６０および第２内側型１７０を弁体３１内から抜き出すとき、第１凸面１６１および第２凸面１７１が弁体３１の内周壁４６２に干渉することなく、第１内側型１６０および第２内側型１７０を弁体３１から容易に抜き出すことができる。 Therefore, when the first inner mold 160 and the second inner mold 170 are extracted from the valve body 31, the first convex surface 161 and the second convex surface 171 do not interfere with the inner peripheral wall 462 of the valve body 31, and the first inner mold 160 And the 2nd inner side type | mold 170 can be easily extracted from the valve body 31.

　型移動工程では、樹脂成形工程の後、内側型（１６０、１７０）を弁体３１の内側へ移動させる。 In the mold moving process, the inner mold (160, 170) is moved to the inside of the valve body 31 after the resin molding process.
　上記製造方法でバルブ３０を製造することにより、弁体３１の外周壁の球面の成形精度を向上できる。これにより、弁体３１の外周壁における冷却水の漏れを抑制可能である。 By manufacturing the valve 30 by the above manufacturing method, the molding accuracy of the spherical surface of the outer peripheral wall of the valve body 31 can be improved. Thereby, the leakage of the cooling water in the outer peripheral wall of the valve body 31 can be suppressed.
　また、弁体内流路３００の流路面積を大きくでき、通水抵抗を小さくできる。 Moreover, the flow passage area of the valve body flow passage 300 can be increased, and the water flow resistance can be reduced.

The pipe portion end 502 has an outer diameter larger than the outer diameter of the pipe portion main body 501.
　そのため、パイプ部端部５０２を例えば無理抜きにより形成する場合、パイプ部端部５０２を内側へ容易に変形させつつ型を抜くことができ、パイプ部端部５０２の割れを抑制できる。これにより、パイプ部端部５０２からの冷却水の漏れを抑制できる。 Therefore, when the pipe part end 502 is formed by, for example, forcibly removing, the mold can be pulled out while easily deforming the pipe part end 502 inward, and cracking of the pipe part end 502 can be suppressed. Thereby, the leakage of the cooling water from the pipe part edge part 502 can be suppressed.
　なお、パイプ部端部５０２の外径がパイプ部本体５０１の外径より大きいため、パイプ部端部５０２に接続したホース等の抜けを抑制できる。 In addition, since the outer diameter of the pipe part end part 502 is larger than the outer diameter of the pipe part main body 501, disconnection of the hose etc. connected to the pipe part end part 502 can be suppressed.

By forming only one pipe protrusion 503 on the pipe 511, the material cost can be reduced. In other embodiments, two pipe protrusions 503 may be formed on the pipe part 511.

Leaks can be noticed by the user. Thereby, it is possible to make the user deal with a leak that needs to be dealt with.
　一方、内部空間２００から駆動部７０側へ流れる冷却水の量が少ない場合、隔壁貫通穴６５、ハウジング貫通穴２７０に冷却水を留めておくことができ、シャフト挿通穴６２における冷却水の漏れをユーザに気付かせないようにすることができる。これにより、対応の必要がない漏れについてまで、ユーザに対応させることを抑制できる。 On the other hand, when the amount of cooling water flowing from the internal space 200 to the drive unit 70 side is small, the cooling water can be retained in the partition wall through hole 65 and the housing through hole 270, and cooling water leaks in the shaft insertion hole 62.

　シャフト３２の軸Ａｘｓ１の真下方向を０度とすると、ハウジング貫通穴２７０は、シャフト３２の周方向の０～８０度の範囲に形成されている。本実施形態では、ハウジング貫通穴２７０は、シャフト３２側から０度の方向へ延びるよう形成されている。そのため、冷却水の漏れが多い場合、冷却水を速やかに排出できる。 <6-21>
When the direction directly below the axis Axs1 of the shaft 32 is 0 degree, the housing through hole 270 is formed in a range of 0 to 80 degrees in the circumferential direction of the shaft 32. In the present embodiment, the housing through hole 270 is formed to extend in the direction of 0 degree from the shaft 32 side. Therefore, when there is much leakage of cooling water, cooling water can be discharged quickly.
　なお、ハウジング貫通穴２７０は、隔壁貫通穴６５と同様に、シャフト３２の周方向の３０～８０度の範囲に形成されていてもよい。この場合、ハウジング貫通穴２７０の角度がある程度緩やかになり、冷却水がにじむように排出できる。そのため、不用意に冷却水が漏れて、問題が生じた場合であっても、ユーザが必要以上に異常と敏感に反応する事態を回避できる。 The housing through hole 270 may be formed in the range of 30 to 80 degrees in the circumferential direction of the shaft 32, similarly to the partition wall through hole 65. In this case, the angle of the housing through hole 270 becomes moderate to some extent, and the cooling water can be discharged so as to ooze. Therefore, even if the cooling water leaks carelessly and a problem arises, it is possible to avoid a situation in which the user reacts more abnormally and sensitively than necessary.

　図５３に示すように、隔壁部６０は、シャフト挿通穴６２の隔壁貫通穴６５と軸シール部材６０３との間において段差を形成する隔壁内側段差面６６２を有している。ここで、隔壁内側段差面６６２は、内部空間２００側を向くよう環状の平面状に形成されている。隔壁内側段差面６６２は、隔壁内側段差面６６１に対し隔壁貫通穴６５側に形成されている。 <6-5>
As shown in FIG. 53, the partition wall 60 has a partition inner step surface 662 that forms a step between the partition through hole 65 of the shaft insertion hole 62 and the shaft seal member 603. Here, the partition inner surface step surface 662 is formed in an annular flat shape so as to face the inner space 200 side. The partition inner step surface 662 is formed on the partition through hole 65 side with respect to the partition inner step surface 661.
　そのため、隔壁内側段差面６６２と軸シール部材６０３との間に空間を形成できる。これにより、冷却水の漏れが少ない場合、当該空間に冷却水を留めておくことで、少量の漏れについてユーザに気付かせないようにすることができる。 Therefore, a space can be formed between the partition inner step surface 662 and the shaft seal member 603. Thereby, when there is little leakage of cooling water, it is possible to prevent the user from noticing a small amount of leakage by keeping the cooling water in the space.
　また、ハウジング貫通穴２７０を経由して外部から水等が侵入したとしても、当該空間に水等を留めておくことで、水等が軸シール部材６０３まで流れるのを抑制できる。 Further, even if water or the like enters from the outside through the housing through hole 270, it is possible to suppress the water or the like from flowing to the shaft seal member 603 by keeping the water or the like in the space.
　ハウジング段差面２８１は、内部空間２００側を向くよう環状に形成されている。隔壁外側段差面６７１は、ハウジング段差面２８１と環状シール部材６００との間において駆動部７０およびハウジング段差面２８１側を向くよう環状に形成されている。ここで、隔壁外側段差面６７１とハウジング段差面２８１とは、対向しながら所定距離離れている。そのため、隔壁部本体６１の外壁とハウジング開口部２１０の内壁との間において環状シール部材６００とハウジング貫通穴２７０との間にラビリンス状の通路Ｐ１が形成されている。 The housing step surface 281 is formed in an annular shape so as to face the inner space 200 side. The partition outer step surface 671 is formed in an annular shape so as to face the drive unit 70 and the housing step surface 281 side between the housing step surface 281 and the annular seal member 600. Here, the partition outer surface step surface 671 and the housing step surface 281 are separated from each other by a predetermined distance while facing each other. Therefore, a labyrinth-shaped passage P <b> 1 is formed between the annular seal member 600 and the housing through hole 270 between the outer wall of the partition wall body 61 and the inner wall of the housing opening 210.
　そのため、ハウジング貫通穴２７０を経由して外部から水等が侵入したとしても、通路Ｐ１に水等を留めておくことで、水等が環状シール部材６００まで流れるのを抑制できる。 Therefore, even if water or the like enters from the outside via the housing through hole 270, the water or the like can be suppressed from flowing to the annular seal member 600 by retaining the water or the like in the passage P <b> 1.
　図５３に示すように、ハウジング開口部２１０の径方向において、ラビリンス状の通路Ｐ１の駆動部７０側の部位の高さＨｐ１は、通路Ｐ１の内部空間２００側の部位の高さＨｐ２より小さい。そのため、ハウジング貫通穴２７０側から見ると、通路Ｐ１は、狭い部位から広い部位となるよう変化している。そのため、通路Ｐ１の狭い部位により、ハウジング貫通穴２７０側から環状シール部材６００側へ水が流れにくくなる。また、通路Ｐ１の狭い部位により、内部空間２００側からハウジング貫通穴２７０側へ水が流れにくくなる。 53, in the radial direction of the housing opening 210, the height Hp1 of the portion on the drive unit 70 side of the labyrinth-shaped passage P1 is smaller than the height Hp2 of the portion on the inner space 200 side of the passage P1. Therefore, when viewed from the housing through hole 270 side, the passage P1 changes from a narrow part to a wide part. Therefore, the narrow portion of the passage P1 makes it difficult for water to flow from the housing through hole 270 side to the annular seal member 600 side. Further, the narrow portion of the passage P1 makes it difficult for water to flow from the internal space 200 side to the housing through hole 270 side.

As shown in FIG. 54, the partition wall through-hole 65 and the housing through-hole 270 are different from each other in the position of the shaft in the shaft (Axh1) direction of the shaft insertion hole 62. Here, the housing through hole 270 is formed on the drive unit 70 side with respect to the partition wall through hole 65.
　そのため、ハウジング貫通穴２７０を経由して外部から水等が侵入したとしても、隔壁貫通穴６５を経由してシャフト挿通穴６２側へ水等が流れるのを抑制できる。 Therefore, even if water or the like enters from the outside via the housing through hole 270, it is possible to suppress the water or the like from flowing to the shaft insertion hole 62 side via the partition wall through hole 65.
＜６－１１－１＞
　図５４に示すように、隔壁貫通穴６５の軸とハウジング貫通穴２７０の軸との距離をＬ、シャフト挿通穴６２の軸（Ａｘｈ１）方向におけるハウジング貫通穴２７０の大きさをＤとすると、隔壁貫通穴６５およびハウジング貫通穴２７０は、Ｄ≦Ｌ≦１０Ｄの関係を満たすよう形成されている。 <6-11-1>
As shown in FIG. 54, when the distance between the axis of the partition wall through hole 65 and the shaft of the housing through hole 270 is L, and the size of the housing through hole 270 in the axis (Axh1) direction of the shaft insertion hole 62 is D, the partition wall The through hole 65 and the housing through hole 270 are formed to satisfy the relationship of D ≦ L ≦ 10D.
　そのため、ハウジング貫通穴２７０を経由して外部から水等が侵入したとしても、隔壁貫通穴６５を経由してシャフト挿通穴６２側へ水等が流れるのをより効果的に抑制できる。 Therefore, even if water or the like enters from the outside via the housing through hole 270, it is possible to more effectively suppress the water or the like from flowing to the shaft insertion hole 62 side via the partition wall through hole 65.

As shown in FIG. 54, the partition wall portion 60 has a partition outside step surface 671 that forms a step between the partition wall through hole 65 on the outer wall of the partition wall body 61 and the housing through hole 270.
　そのため、ハウジング貫通穴２７０を経由して外部から水等が侵入したとしても、隔壁外側段差面６７１に水等を留めておくことで、隔壁貫通穴６５を経由してシャフト挿通穴６２側へ水等が流れるのを抑制できる。 Therefore, even if water or the like enters from the outside via the housing through hole 270, the water is retained on the partition outer stepped surface 671, so that the water is passed to the shaft insertion hole 62 side via the partition through hole 65. Etc. can be suppressed.
　図５４に示すように、ハウジング貫通穴２７０は、ハウジング段差面２８２、隔壁外側段差面６７１に対し駆動部７０側に形成されている。ここで、隔壁外側段差面６７１とハウジング段差面２８２とは、対向しながら所定距離離れている。そのため、隔壁部本体６１の外壁とハウジング開口部２１０の内壁との間においてハウジング貫通穴２７０と隔壁貫通穴６５との間にラビリンス状の通路Ｐ２が形成されている。 As shown in FIG. 54, the housing through hole 270 is formed on the drive unit 70 side with respect to the housing step surface 282 and the partition outer surface step surface 671. Here, the partition outer surface step surface 671 and the housing step surface 282 are separated from each other by a predetermined distance while facing each other. Therefore, a labyrinth-shaped passage P <b> 2 is formed between the housing through hole 270 and the partition wall through hole 65 between the outer wall of the partition wall body 61 and the inner wall of the housing opening 210.
　そのため、ハウジング貫通穴２７０を経由して外部から水等が侵入したとしても、通路Ｐ２に水等を留めておくことで、隔壁貫通穴６５を経由してシャフト挿通穴６２側へ水等が流れるのを抑制できる。 Therefore, even if water or the like enters from the outside via the housing through hole 270, the water or the like flows to the shaft insertion hole 62 side via the partition wall through hole 65 by keeping the water or the like in the passage P <b> 2. Can be suppressed.
　図５４に示すように、ハウジング開口部２１０の径方向において、ラビリンス状の通路Ｐ２の駆動部７０側の部位の高さＨｐ１は、通路Ｐ２の内部空間２００側の部位の高さＨｐ２より小さい。そのため、ハウジング貫通穴２７０側から見ると、通路Ｐ２は、狭い部位から広い部位となるよう変化している。そのため、通路Ｐ２の狭い部位により、ハウジング貫通穴２７０側から隔壁貫通穴６５側へ水が流れにくくなる。また、通路Ｐ２の狭い部位により、隔壁貫通穴６５側からハウジング貫通穴２７０側へ水が流れにくくなる。 54, in the radial direction of the housing opening 210, the height Hp1 of the portion on the drive unit 70 side of the labyrinth-shaped passage P2 is smaller than the height Hp2 of the portion on the inner space 200 side of the passage P2. Therefore, when viewed from the housing through hole 270 side, the passage P2 changes from a narrow part to a wide part. Therefore, the narrow portion of the passage P2 makes it difficult for water to flow from the housing through hole 270 side to the partition wall through hole 65 side. Further, the narrow portion of the passage P2 makes it difficult for water to flow from the partition wall through hole 65 side to the housing through hole 270 side.
　他の実施形態では、ハウジング開口部２１０の径方向において、ラビリンス状の通路Ｐ２の駆動部７０側の部位の高さＨｐ１は、通路Ｐ２の内部空間２００側の部位の高さＨｐ２より大きくてもよい。この場合、ハウジング貫通穴２７０側から見ると、通路Ｐ２は、広い部位から狭い部位となるよう変化することになる。そのため、ハウジング貫通穴２７０から侵入した外部の水は、通路Ｐ２の狭い部位でトラップされ、隔壁貫通穴６５側へ流れにくくなる。一方、隔壁貫通穴６５側の水は、通路Ｐ２を経由してハウジング貫通穴２７０側へ流れやすくなる。 In another embodiment, in the radial direction of the housing opening 210, the height Hp1 of the portion on the drive unit 70 side of the labyrinth-shaped passage P2 is greater than the height Hp2 of the portion on the inner space 200 side of the passage P2. Good. In this case, when viewed from the housing through hole 270 side, the passage P2 changes from a wide part to a narrow part. Therefore, the external water that has entered from the housing through hole 270 is trapped in a narrow portion of the passage P2 and hardly flows to the partition wall through hole 65 side. On the other hand, the water on the partition through hole 65 side easily flows to the housing through hole 270 side via the passage P2.

　図７９～８２に示すように、保持部材７３は、スナップフィット部７３１を１つ有している。図７９、８０に示すように、保持部材７３は、スナップフィット部７３１がウォームギア７１２の径方向外側に位置するよう形成されている。 <2-12>
As shown in FIGS. 79 to 82, the holding member 73 has one snap fit portion 731. As shown in FIGS. 79 and 80, the holding member 73 is formed such that the snap fit portion 731 is positioned on the radially outer side of the worm gear 712.
　そのため、モータ本体７１０の両側にスナップフィット部７３１が２つずつ形成される第１実施形態の保持部材７３（図８７～８９参照）と比べ、モータ７１の軸Ａｘｍ１に垂直な方向、すなわち、取付面２０１に対し垂直な方向Ｄｖ１における保持部材７３の体格を小さくすることができる。そのため、取付面２０１に対し垂直な方向Ｄｖ１における駆動部カバー８０およびバルブ装置１０の体格を小さくできる。 Therefore, compared to the holding member 73 (see FIGS. 87 to 89) of the first embodiment in which two snap fit portions 731 are formed on both sides of the motor body 710, the direction perpendicular to the axis Axm1 of the motor 71, that is, the mounting The size of the holding member 73 in the direction Dv1 perpendicular to the surface 201 can be reduced. Therefore, the physique of the drive part cover 80 and the valve apparatus 10 in the direction Dv1 perpendicular to the mounting surface 201 can be reduced.
　また、モータ本体７１０の両側にスナップフィット部７３１が２つずつ形成される第１実施形態（図８７参照）と比べ、モータ７１を取付面２０１、すなわち、エンジン２に近付けることができるため、モータ７１にかかる振動が小さくなり、断線に対するロバスト性を向上できる。 Further, compared to the first embodiment (see FIG. 87) in which two snap fit portions 731 are formed on both sides of the motor body 710, the motor 71 can be brought closer to the mounting surface 201, that is, the engine 2, so that the motor The vibration concerning 71 becomes small and the robustness with respect to a disconnection can be improved.
　図６１～６５に示すように、パイプ部材５０のパイプ部５１２は、駆動部カバー８０に向かって傾斜しながら延びるよう形成されている。 61 to 65, the pipe part 512 of the pipe member 50 is formed to extend while inclining toward the drive part cover 80.

　図６７に示すように、保持部材７３は、スナップフィット部７３１が回転軸Ａｘｒ１に対しパイプ部材５０側に位置するよう形成されている。 <2-13>
As shown in FIG. 67, the holding member 73 is formed such that the snap fit portion 731 is positioned on the pipe member 50 side with respect to the rotation axis Axr1.
　そのため、取付面２０１に対し垂直な方向Ｄｖ１における駆動部カバー８０の体格を小さくでき、駆動部カバー８０がパイプ部材５０の特にパイプ部５１２に干渉するのを抑制できる。 Therefore, the size of the drive unit cover 80 in the direction Dv1 perpendicular to the attachment surface 201 can be reduced, and the drive unit cover 80 can be prevented from interfering with the pipe portion 512 of the pipe member 50 in particular.
　他の実施形態では、スナップフィット部７３１は、第３ギア７２３とモータ側端子７１３との間に位置するよう形成されていてもよい（図８０、８３参照）。 In other embodiments, the snap fit portion 731 may be formed to be positioned between the third gear 723 and the motor side terminal 713 (see FIGS. 80 and 83).
　この場合でも、モータ本体７１０の両側にスナップフィット部７３１が２つずつ形成される第１実施形態の保持部材７３（図８７～８９参照）と比べ、モータ７１の軸Ａｘｍ１に垂直な方向、すなわち、取付面２０１に対し垂直な方向Ｄｖ１における保持部材７３の体格を小さくすることができる。 Even in this case, compared to the holding member 73 (see FIGS. 87 to 89) of the first embodiment in which two snap fit portions 731 are formed on both sides of the motor main body 710, the direction perpendicular to the axis Axm1 of the motor 71, that is, The physique of the holding member 73 in the direction Dv1 perpendicular to the mounting surface 201 can be reduced.
　図９０～１０２に、本実施形態のバルブ３０およびその一部を示す。 90 to 102 show the valve 30 of this embodiment and a part thereof.
　本実施形態のバルブ３０は、弁体３１の形状等が第１、３実施形態のバルブ３０と類似する。本実施形態のバルブ３０は、ボールバルブ４１、筒状接続部４４、ボールバルブ４２、筒状バルブ接続部４５、ボールバルブ４３の並び方向が第３実施形態と異なり、第１実施形態と同様である。すなわち、本実施形態のバルブ３０は、回転軸Ａｘｒ１方向の駆動部７０とは反対側から駆動部７０側に向かって、ボールバルブ４１、筒状接続部４４、ボールバルブ４２、筒状バルブ接続部４５、ボールバルブ４３の順で並ぶようにして形成されている。ボールバルブ４１、４２、４３は、それぞれ、出口ポート２２１、２２２、２２３を開閉可能に設けられている（図６７参照）。 The valve 30 of the present embodiment is similar to the valve 30 of the first and third embodiments in the shape of the valve body 31 and the like. The valve 30 of the present embodiment differs from the third embodiment in the arrangement direction of the ball valve 41, the cylindrical connection portion 44, the ball valve 42, the cylindrical valve connection portion 45, and the ball valve 43, and is the same as the first embodiment. is there. That is, the valve 30 of the present embodiment is configured such that the ball valve 41, the cylindrical connecting portion 44, the ball valve 42, and the cylindrical valve connecting portion from the side opposite to the driving portion 70 in the direction of the rotation axis Axr1 toward the driving portion 70. 45 and the ball valve 43 are arranged in this order. The ball valves 41, 42, and 43 are provided so that the outlet ports 221, 222, and 223 can be opened and closed, respectively (see FIG. 67).
　図９３、９４等に示すように、ボールバルブ４１の弁体開口部４１０は、大開口部４１２、延伸開口部４１３を有している。大開口部４１２は、第１分割体３３の周方向の一端から他端側へ向かって延びるよう形成されている。延伸開口部４１３は、大開口部４１２の他端から第１分割体３３の周方向の他端近傍まで延びるよう形成されている。延伸開口部４１３の回転軸Ａｘｒ１方向の大きさは、大開口部４１２の回転軸Ａｘｒ１方向の大きさより小さい。弁体開口部４１０の開口面積は、大開口部４１２の開口面積と延伸開口部４１３の開口面積とを合わせた面積である。 93, 94, etc., the valve body opening 410 of the ball valve 41 has a large opening 412 and an extended opening 413. The large opening 412 is formed to extend from one end in the circumferential direction of the first divided body 33 toward the other end. The extending opening 413 is formed to extend from the other end of the large opening 412 to the vicinity of the other end in the circumferential direction of the first divided body 33. The size of the extending opening 413 in the direction of the rotation axis Axr1 is smaller than the size of the large opening 412 in the direction of the rotation axis Axr1. The opening area of the valve body opening 410 is the total of the opening area of the large opening 412 and the opening area of the extended opening 413.
　弁体開口部４１０が延伸開口部４１３を有していることにより、出口ポート２２１の開弁初期において、ラジエータ５への冷却水の流量を徐々に大きくすることができる。これにより、ラジエータ５の熱交換による冷却水の急激な温度変化を抑制することができる。 Since the valve body opening 410 has the extended opening 413, the flow rate of the cooling water to the radiator 5 can be gradually increased at the initial opening of the outlet port 221. Thereby, the rapid temperature change of the cooling water by the heat exchange of the radiator 5 can be suppressed.
　本実施形態では、弁体開口部４１０のみ、延伸開口部４１３を有している。これに対し、他の実施形態では、弁体開口部４２０、４３０にも延伸開口部４１３と同様の開口部を設けてもよい。この場合、ヒータ６、デバイス７の熱交換による冷却水の急激な温度変化を抑制することができる。 In the present embodiment, only the valve body opening 410 has the extended opening 413. On the other hand, in other embodiments, the valve body openings 420 and 430 may be provided with openings similar to the extension openings 413. In this case, a rapid temperature change of the cooling water due to heat exchange between the heater 6 and the device 7 can be suppressed.
＜３－２９＞
　第１ボールバルブとしてのボールバルブ４１の弁体開口部４１０の大きさは、第２ボールバルブとしてのボールバルブ４２の弁体開口部４２０の大きさ、および、第３ボールバルブとしてのボールバルブ４３の弁体開口部４３０の大きさより大きい。 <3-29>
The size of the valve body opening 410 of the ball valve 41 as the first ball valve is the same as the size of the valve body opening 420 of the ball valve 42 as the second ball valve and the ball valve 43 as the third ball valve. It is larger than the size of the valve body opening 430.
　すなわち、２つのボールバルブが連続するよう形成されたボールバルブ４２、４３の弁体開口部４２０、４３０は小さく、１つのボールバルブとして形成されたボールバルブ４１の弁体開口部４１０は最も大きい。 That is, the valve body openings 420 and 430 of the ball valves 42 and 43 formed so that two ball valves are continuous are small, and the valve body opening 410 of the ball valve 41 formed as one ball valve is the largest.
　ボールバルブ４２、４３とボールバルブ４１との間のバルブ間空間４００には、入口ポート２２０からの冷却水が流入する。その後、冷却水は、ボールバルブ４２、４３側とボールバルブ４１側とに分配される。ここで、ボールバルブ４２、４３側とボールバルブ４１側とで必要とされる冷却水の量が偏ると、冷却水の分配が適切にできないため、最も開口の大きい弁体開口部４１０が形成されたボールバルブ４１は、必要とされる冷却水が多いため、他の開口の小さい弁体開口部４２０、４３０が形成されたボールバルブ４２、４３とは連続させていない。つまり、ボールバルブを２連とすると、２つのボールバルブの開口分の冷却水が必要となるため、極力、開口の小さいボールバルブ（４２、４３）同士を連続させたものである。 The cooling water from the inlet port 220 flows into the inter-valve space 400 between the ball valves 42 and 43 and the ball valve 41. Thereafter, the cooling water is distributed to the ball valves 42 and 43 side and the ball valve 41 side. Here, if the amount of cooling water required on the ball valves 42 and 43 side and the ball valve 41 side is biased, the distribution of the cooling water cannot be performed properly, so that the valve body opening portion 410 having the largest opening is formed. Since the ball valve 41 requires a large amount of cooling water, it is not continuous with the ball valves 42 and 43 in which the valve body openings 420 and 430 having other small openings are formed. That is, if the ball valves are doubled, the cooling water for the openings of the two ball valves is required, so that the ball valves (42, 43) having small openings are made continuous as much as possible.

　図６２に示すように、ハウジング２０は、ハウジング本体２１の外壁から突出するようハウジング本体２１とは異なる部位として形成されたハウジング側カバー固定部（２９１～２９６）を有する。 <4-4>
As shown in FIG. 62, the housing 20 has housing-side cover fixing portions (291 to 296) formed as portions different from the housing main body 21 so as to protrude from the outer wall of the housing main body 21.
　駆動部カバー８０は、駆動部空間８００を形成するカバー本体８１、および、カバー本体８１の外壁から突出するようカバー本体８１とは異なる部位として形成されハウジング側カバー固定部（２９１～２９６）に固定されるカバー固定部（８２１～８２６）を有する。 The drive unit cover 80 is formed as a portion different from the cover main body 81 so as to protrude from the outer wall of the cover main body 81 forming the drive unit space 800 and fixed to the housing side cover fixing portions (291 to 296). Cover fixing portions (821 to 826).
　カバー固定部（８２１～８２６）は、ハウジング本体２１の取付面２０１に平行な方向Ｄｐ１の両端部（２１５、２１６）のうち少なくとも一方より外側へ突出しないよう形成されている。本実施形態では、カバー固定部（８２１～８２６）は、ハウジング本体２１の取付面２０１に平行な方向Ｄｐ１の両端部（２１５、２１６）より外側へ突出しないよう形成されている。ここで、ハウジング本体２１の取付面２０１に平行な方向Ｄｐ１の両端部であるハウジング端部２１５、２１６は、ハウジング側カバー固定部２９１～２９６とは異なる部位としてハウジング本体２１に形成されている。 The cover fixing portions (821 to 826) are formed so as not to protrude outward from at least one of both end portions (215, 216) in the direction Dp1 parallel to the mounting surface 201 of the housing body 21. In the present embodiment, the cover fixing portions (821 to 826) are formed so as not to protrude outward from both end portions (215, 216) in the direction Dp1 parallel to the mounting surface 201 of the housing body 21. Here, the housing end portions 215 and 216 which are both ends in the direction Dp1 parallel to the mounting surface 201 of the housing main body 21 are formed in the housing main body 21 as portions different from the housing side cover fixing portions 291 to 296.
　そのため、駆動部カバー８０の取付面２０１に平行な方向Ｄｐ１の体格を小さくでき、バルブ装置１０の取付面２０１に平行な方向Ｄｐ１の体格を小さくできる。これにより、バルブ装置１０を車両１の狭小空間Ａ１に搭載できる。 Therefore, the size in the direction Dp1 parallel to the mounting surface 201 of the drive unit cover 80 can be reduced, and the size in the direction Dp1 parallel to the mounting surface 201 of the valve device 10 can be reduced. Thereby, the valve device 10 can be mounted in the narrow space A1 of the vehicle 1.
　本実施形態では、取付面２０１に平行な方向Ｄｐ１は、鉛直方向に対し垂直な方向、すなわち、水平方向に平行な方向である。また、取付面２０１に平行な方向Ｄｐ１は、取付面２０１に対し垂直な方向Ｄｖ１に対し垂直である。 In this embodiment, the direction Dp1 parallel to the mounting surface 201 is a direction perpendicular to the vertical direction, that is, a direction parallel to the horizontal direction. The direction Dp1 parallel to the attachment surface 201 is perpendicular to the direction Dv1 perpendicular to the attachment surface 201.

　図６２に示すように、ハウジング本体２１がエンジン２に取り付けられた状態において、カバー固定部８２１～８２６は、ハウジング本体２１の取付面２０１に平行な方向Ｄｐ１かつ水平方向の両端部（２１５、２１６）のうち少なくとも一方より外側へ突出しないよう形成されている。本実施形態では、カバー固定部８２１～８２６は、ハウジング本体２１の取付面２０１に平行な方向Ｄｐ１かつ水平方向の両端部（２１５、２１６）より外側へ突出しないよう形成されている。つまり、カバー固定部８２１～８２６は、ハウジング端部２１５、２１６よりも、ハウジング本体２１の最薄方向である取付面２０１に平行な方向Ｄｐ１に関して突出しないよう形成されている。 <4-5>
As shown in FIG. 62, in a state where the housing main body 21 is attached to the engine 2, the cover fixing portions 821 to 826 are arranged in the direction Dp1 parallel to the mounting surface 201 of the housing main body 21 and both ends in the horizontal direction (215, 216 ) So as not to protrude outwardly from at least one of them. In the present embodiment, the cover fixing portions 821 to 826 are formed so as not to protrude outward from both ends (215, 216) in the direction Dp1 parallel to the mounting surface 201 of the housing body 21 and in the horizontal direction. That is, the cover fixing portions 821 to 826 are formed so as not to protrude with respect to the direction Dp1 parallel to the attachment surface 201 which is the thinnest direction of the housing main body 21, rather than the housing end portions 215 and 216.
　そのため、駆動部カバー８０の取付面２０１に平行な方向Ｄｐ１かつ水平方向の体格を小さくでき、バルブ装置１０の取付面２０１に平行な方向Ｄｐ１かつ水平方向の体格を小さくできる。これにより、取付面２０１に平行な方向Ｄｐ１かつ水平方向に狭い狭小空間Ａ１にバルブ装置１０を搭載できる。 Therefore, the size Dp1 parallel to the mounting surface 201 of the drive unit cover 80 and the horizontal size can be reduced, and the size Dp1 parallel to the mounting surface 201 of the valve device 10 and the horizontal size can be reduced. Thereby, the valve device 10 can be mounted in a narrow space A1 that is parallel to the mounting surface 201 and narrow in the horizontal direction Dp1.
　本実施形態では、オルタネータ１２とインテークマニホールド１１との間の狭小空間Ａ１（図２、６２参照）にバルブ装置１０が設けられるため、バルブ装置１０の取付面２０１に平行な方向Ｄｐ１の体格を小さくすることで、バルブ装置１０をオルタネータ１２とインテークマニホールド１１とに干渉することなく狭小空間Ａ１に設けることができる。 In this embodiment, since the valve device 10 is provided in the narrow space A1 (see FIGS. 2 and 62) between the alternator 12 and the intake manifold 11, the physique in the direction Dp1 parallel to the mounting surface 201 of the valve device 10 is reduced. Thus, the valve device 10 can be provided in the narrow space A1 without interfering with the alternator 12 and the intake manifold 11.

　本実施形態は、車両１のエンジン２の冷却水を制御可能なバルブ装置１０であって、ハウジング２０とバルブ３０とパイプ部材５０と隔壁部６０と駆動部カバー８０と駆動部７０と固定部材８３０とを備える。 <7-1> Housing-side Cover Fixing Section This embodiment is a valve device 10 capable of controlling the cooling water of the engine 2 of the vehicle 1, and includes a housing 20, a valve 30, a pipe member 50, a partition wall 60, and a driving unit. The cover 80, the drive part 70, and the fixing member 830 are provided.
　図６１、６２、６４～６８、７３～７８に示すように、ハウジング２０は、内側に内部空間２００を形成するハウジング本体２１、内部空間２００とハウジング本体２１の外部とを接続するポート（２２０、２２１、２２２、２２３、２２４）、ハウジング本体２１の外壁から突出するようハウジング本体２１とは異なる部位として形成されたハウジング側カバー固定部２９１～２９６、および、ハウジング側カバー固定部２９１～２９６に形成されたハウジング側カバー締結穴２９０を有する。 As shown in FIGS. 61, 62, 64 to 68, and 73 to 78, the housing 20 includes a housing main body 21 that forms an internal space 200 inside, and ports (220, 220) that connect the internal space 200 and the outside of the housing main body 21. 221, 222, 223, 224), formed on housing side cover fixing portions 291 to 296 formed as portions different from the housing main body 21 so as to protrude from the outer wall of the housing main body 21, and housing side cover fixing portions 291 to 296. The housing side cover fastening hole 290 is formed.
　バルブ３０は、内部空間２００内において回転軸Ａｘｒ１周りに回転可能な弁体３１、および、回転軸Ａｘｒ１に設けられたシャフト３２を有し、弁体３１の回転位置によりポート（２２１、２２２、２２３）を開閉可能である。 The valve 30 includes a valve body 31 that can rotate around the rotation axis Axr1 in the internal space 200, and a shaft 32 that is provided on the rotation axis Axr1, and ports (221, 222, 223) depending on the rotational position of the valve body 31. ) Can be opened and closed.
　パイプ部材５０は、内側の空間がポート（２２１、２２２、２２３、２２４）に連通する筒状のパイプ部（５１１、５１２、５１３、５１４）を有し、ハウジング本体２１に取り付けられている。 The pipe member 50 has a cylindrical pipe portion (511, 512, 513, 514) whose inner space communicates with the ports (221, 222, 223, 224), and is attached to the housing body 21.
　隔壁部６０は、内部空間２００とハウジング本体２１の外部とを隔てるよう設けられ、シャフト３２の一端を挿通可能なよう形成されたシャフト挿通穴６２を有する。 The partition wall portion 60 is provided so as to separate the internal space 200 from the outside of the housing body 21 and has a shaft insertion hole 62 formed so that one end of the shaft 32 can be inserted.
　駆動部カバー８０は、隔壁部６０に対し内部空間２００とは反対側に設けられ、隔壁部６０との間に駆動部空間８００を形成するカバー本体８１、カバー本体８１の外壁から突出するようカバー本体８１とは異なる部位として形成されたカバー固定部８２１～８２６、および、カバー固定部８２１～８２６に形成されたカバー締結穴８３１～８３６を有する。 The drive unit cover 80 is provided on the opposite side of the partition wall 60 from the internal space 200, and covers the cover body 81 that forms the drive space 800 between the partition wall 60 and the outer wall of the cover body 81. Cover fixing portions 821 to 826 formed as parts different from the main body 81 and cover fastening holes 831 to 836 formed in the cover fixing portions 821 to 826 are provided.
　駆動部７０は、駆動部空間８００に設けられ、シャフト３２の一端を経由して弁体３１を回転駆動可能である。 The drive unit 70 is provided in the drive unit space 800 and can rotate the valve body 31 via one end of the shaft 32.
　固定部材８３０は、カバー締結穴８３１～８３６を通りハウジング側カバー締結穴２９０に螺合することでカバー固定部８２１～８２６とハウジング側カバー固定部２９１～２９６とを固定する。 The fixing member 830 passes through the cover fastening holes 831 to 836 and is screwed into the housing side cover fastening holes 290 to fix the cover fixing portions 821 to 826 and the housing side cover fixing portions 291 to 296.
　ハウジング側カバー固定部２９１～２９６は、ハウジング本体２１の外壁から突出するカバー固定基部２９８、および、カバー固定基部２９８からカバー固定部８２１～８２６側へ突出しカバー固定部８２１～８２６に固定されるカバー固定突出部２９９を有している。 The housing side cover fixing portions 291 to 296 are a cover fixing base portion 298 protruding from the outer wall of the housing main body 21, and a cover protruding from the cover fixing base portion 298 toward the cover fixing portions 821 to 826 and fixed to the cover fixing portions 821 to 826. It has a fixed protrusion 299.
　図６４等に示すように、パイプ部材５０の少なくとも一部は、カバー固定基部２９８に対しカバー固定突出部２９９とは反対側に位置している。 As shown in FIG. 64 and the like, at least a part of the pipe member 50 is located on the opposite side of the cover fixing projection 299 with respect to the cover fixing base 298.
　このように、カバー固定突出部２９９がカバー固定基部２９８からパイプ部材５０とは反対側へ突出するよう形成されているため、ハウジング側カバー固定部２９１～２９６とパイプ部材５０との干渉を抑制でき、パイプ部材５０の搭載自由度を向上できる。また、バルブ装置１０の回転軸Ａｘｒ１方向の体格を小さくできる。したがって、車両１の狭小空間Ａ１にバルブ装置１０を容易に搭載することができる。 Thus, since the cover fixing projection 299 is formed so as to protrude from the cover fixing base 298 to the side opposite to the pipe member 50, interference between the housing side cover fixing portions 291 to 296 and the pipe member 50 can be suppressed. The degree of freedom of mounting the pipe member 50 can be improved. Further, the size of the valve device 10 in the direction of the rotation axis Axr1 can be reduced. Therefore, the valve device 10 can be easily mounted in the narrow space A1 of the vehicle 1.
　なお、本実施形態では、パイプ部材５０の少なくとも一部は、ハウジング側カバー固定部２９１～２９３のカバー固定基部２９８に対しカバー固定突出部２９９とは反対側に位置している（図６４等参照）。 In this embodiment, at least a part of the pipe member 50 is located on the opposite side of the cover fixing protrusion 299 with respect to the cover fixing base 298 of the housing side cover fixing parts 291 to 293 (see FIG. 64 and the like). ).

　図７３等に示すように、カバー固定突出部２９９は、カバー本体８１の外壁との間に隙間としてのカバー間隙間Ｓｃ１を形成している。 <7-2>
As shown in FIG. 73 and the like, the cover fixing protrusion 299 forms an inter-cover gap Sc1 as a gap with the outer wall of the cover main body 81.
　そのため、駆動部カバー８０を固定部材８３０によりハウジング２０に締結したとき、ハウジング側カバー固定部２９１～２９６のカバー固定突出部２９９に割れが生じても、この割れがハウジング本体２１にまで及ぶことを抑制できる。これにより、ハウジング２０への駆動部カバー８０の締結によって生じ得る冷却水の漏れを効果的に抑制できる。 Therefore, when the drive unit cover 80 is fastened to the housing 20 by the fixing member 830, even if a crack occurs in the cover fixing projection 299 of the housing side cover fixing portions 291 to 296, the crack may reach the housing body 21. Can be suppressed. Thereby, the leakage of the cooling water which may arise by the fastening of the drive part cover 80 to the housing 20 can be suppressed effectively.

　図７３に示すように、ハウジング側カバー締結穴２９０の軸方向の長さＬ４は、ハウジング側カバー締結穴２９０の軸方向におけるカバー固定基部２９８の長さＬ１とカバー固定突出部２９９の長さＬ２とを合わせた長さＬ３より短い。すなわち、Ｌ４＜Ｌ３＝Ｌ１＋Ｌ２である。 <7-3>
As shown in FIG. 73, the axial length L4 of the housing side cover fastening hole 290 is equal to the length L1 of the cover fixing base 298 and the length L2 of the cover fixing protrusion 299 in the axial direction of the housing side cover fastening hole 290. Is shorter than the combined length L3. That is, L4 <L3 = L1 + L2.
　そのため、ハウジング側カバー固定部２９１～２９６の強度を確保できる。 Therefore, the strength of the housing side cover fixing portions 291 to 296 can be secured.
＜７－４＞
　図７３に示すように、ハウジング側カバー締結穴２９０の内側における固定部材８３０の軸方向の長さＬ５は、ハウジング側カバー締結穴２９０の軸方向の長さＬ４より短い。すなわち、Ｌ５＜Ｌ４である。 <7-4>
As shown in FIG. 73, the axial length L5 of the fixing member 830 inside the housing side cover fastening hole 290 is shorter than the axial length L4 of the housing side cover fastening hole 290. That is, L5 <L4.
　そのため、ハウジング側カバー締結穴２９０への固定部材８３０の螺合時にハウジング側カバー固定部２９１～２９６が割れるのを抑制できる。また、固定部材８３０の先端がカバー固定基部２９８に対しカバー固定突出部２９９とは反対側へ飛び出すことがないため、固定部材８３０の先端がパイプ部材５０に干渉するのを抑制できる。 Therefore, the housing-side cover fixing portions 291 to 296 can be prevented from cracking when the fixing member 830 is screwed into the housing-side cover fastening hole 290.

　そのため、シャフト軸受部９０は内部空間２００の鉛直方向上側に位置し、内部空間２００内の冷却水中の空気は、軸受部本体９１の内側に溜まりやすい。しかしながら、軸受部本体９１の内側に空気が溜まったとしても、軸受部流路９２を経由して当該空気を軸受部本体９１の外側へ排出することができる。 Therefore, the shaft bearing portion 90 is positioned on the upper side in the vertical direction of the internal space 200, and the air in the cooling water in the internal space 200 tends to accumulate inside the bearing portion main body 91. However, even if air accumulates inside the bearing portion main body 91, the air can be discharged to the outside of the bearing portion main body 91 via the bearing portion flow path 92.
　本実施形態では、軸受部本体９１は、略円筒状に形成されている。軸受部流路９２は、軸受部本体９１の対向内壁２１３側の端部から対向内壁２１３とは反対側の端部まで延びるよう形成されている。軸受部流路９２は、軸受部本体９１の軸を挟むようにして軸受部本体９１の周方向に等間隔で２つ形成されている（図１０７参照）。 In the present embodiment, the bearing portion main body 91 is formed in a substantially cylindrical shape. The bearing portion flow path 92 is formed so as to extend from an end portion on the opposite inner wall 213 side of the bearing portion main body 91 to an end portion on the opposite side to the opposite inner wall 213. Two bearing part flow paths 92 are formed at equal intervals in the circumferential direction of the bearing part main body 91 so as to sandwich the shaft of the bearing part main body 91 (see FIG. 107).
　図１０７に示すように、内側軸受部９３には、軸受切欠き部９３１が形成されている。内側軸受部９３は、例えばＰＰＳ等の樹脂により、略円筒状に形成されている。軸受切欠き部９３１は、内側軸受部９３の内周壁と外周壁とを接続しつつ、内側軸受部９３の一方の端部から他方の端部まで延びるよう形成されている。 As shown in FIG. 107, the inner bearing portion 93 is formed with a bearing notch portion 931. The inner bearing portion 93 is formed in a substantially cylindrical shape with a resin such as PPS, for example. The bearing notch portion 931 is formed to extend from one end portion of the inner bearing portion 93 to the other end portion while connecting the inner peripheral wall and the outer peripheral wall of the inner bearing portion 93.
　そのため、内側軸受部９３の内側に空気が溜まったとしても、軸受切欠き部９３１を経由して当該空気を内側軸受部９３の外側へ排出することができる。また、内側軸受部９３に軸受切欠き部９３１が形成されていることにより、内側軸受部９３をシャフト３２の端部と軸受部本体９１との間に容易に配置できる。 Therefore, even if air accumulates inside the inner bearing portion 93, the air can be discharged to the outside of the inner bearing portion 93 via the bearing notch portion 931. Further, since the bearing notch portion 931 is formed in the inner bearing portion 93, the inner bearing portion 93 can be easily disposed between the end portion of the shaft 32 and the bearing portion main body 91.
　軸受切欠き部９３１は、内側軸受部９３の一方の端部から他方の端部まで、内側軸受部９３の軸に対し傾斜しながら延びるよう形成されている。 The bearing notch portion 931 is formed to extend from one end portion of the inner bearing portion 93 to the other end portion while being inclined with respect to the axis of the inner bearing portion 93.
　そのため、内側軸受部９３の周方向の任意の部位において、軸方向の位置に関係なく、内側軸受部９３の内周壁をシャフト３２の端部の外周壁に当接させることができる。これにより、内側軸受部９３に軸受切欠き部９３１を形成した構成において、シャフト３２を安定して軸受けできる。 Therefore, the inner peripheral wall of the inner bearing portion 93 can be brought into contact with the outer peripheral wall of the end portion of the shaft 32 at any portion in the circumferential direction of the inner bearing portion 93 regardless of the position in the axial direction. Thereby, in the structure which formed the bearing notch part 931 in the inner side bearing part 93, the shaft 32 can be bearing stably.
　図１０５、１０６に示すように、軸受部本体９１は、出口ポート２２１の鉛直方向上側の端部の下側まで延びるよう形成されている。つまり、軸受部本体９１の先端部は、出口ポート２２１の鉛直方向上側の端部よりも下側に位置している。 105 and 106, the bearing portion main body 91 is formed so as to extend to the lower side of the upper end portion of the outlet port 221 in the vertical direction. That is, the front end portion of the bearing portion main body 91 is located below the end portion on the upper side in the vertical direction of the outlet port 221.
　そのため、軸受部本体９１の内側の空気を、出口ポート２２１を経由してハウジング本体２１の外部へ容易に排出できる。 Therefore, the air inside the bearing body 91 can be easily discharged to the outside of the housing body 21 via the outlet port 221.
＜１０－１＞非真円ハウジング内壁
　本実施形態は、車両１のエンジン２の冷却水を制御可能なバルブ装置１０であって、ハウジング２０とバルブ３０とを備えている。 <10-1> Inner Wall of Non-Perfect Housing This embodiment is a valve device 10 that can control the cooling water of the engine 2 of the vehicle 1, and includes a housing 20 and a valve 30.
　ハウジング２０は、内側に内部空間２００を形成する筒状のハウジング内壁２１１が形成されたハウジング本体２１、ハウジング内壁２１１に開口し内部空間２００とハウジング本体２１の外部とを接続するポート（２２０、２２１、２２２、２２３）を有する。 The housing 20 includes a housing main body 21 in which a cylindrical housing inner wall 211 forming an inner space 200 is formed inside, and ports (220, 221) that open in the housing inner wall 211 and connect the inner space 200 and the outside of the housing main body 21. , 222, 223).
　図６７、１０８に示すように、バルブ３０は、内部空間２００内においてハウジング内壁２１１の軸Ａｘｎ１に沿う回転軸Ａｘｒ１周りに回転可能な弁体３１、および、弁体３１の外周壁と内周壁とを接続するよう形成された弁体開口部（４１０、４２０、４３０）を有し、弁体３１の回転位置によりポートを開閉可能である。本実施形態では、軸Ａｘｎ１と回転軸Ａｘｒ１とは一致する。 As shown in FIGS. 67 and 108, the valve 30 includes a valve body 31 that can rotate around the rotation axis Axr1 along the axis Axn1 of the housing inner wall 211 in the internal space 200, and an outer peripheral wall and an inner peripheral wall of the valve body 31. The valve body opening (410, 420, 430) formed so as to be connected to each other, and the port can be opened and closed depending on the rotational position of the valve body 31. In the present embodiment, the axis Axn1 and the rotation axis Axr1 coincide.
　図１０８、１０９に示すように、ハウジング内壁２１１は、軸Ａｘｎ１からの距離Ｄｎａ１が周方向で異なるよう形成されている。 108 and 109, the housing inner wall 211 is formed such that the distance Dna1 from the axis Axn1 is different in the circumferential direction.
　そのため、弁体３１の回転軸Ａｘｒ１に垂直な断面における弁体３１の外周壁の形状が円形の場合、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１は、周方向で異なる。すなわち、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１は周方向で一定ではなく、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０は、周方向で大きな部分（隙間Ｓｂ０１）と小さな部分（隙間Ｓｂ０２）とが形成される（図１０９参照）。これにより、内部空間２００の冷却水中の異物が弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０に入り込んだ場合でも、弁体３１が回転することにより異物は大きな隙間Ｓｂ０１に移動し、当該隙間Ｓｂ０１から異物を容易に排出することができる。したがって、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０に異物が留まり続けることによる弁体３１の作動不良を抑制することができる。また、弁体３１の駆動に関する負荷トルクの増大、および、圧損抵抗の増大を抑制することができる。 Therefore, when the shape of the outer peripheral wall of the valve body 31 in a cross section perpendicular to the rotation axis Axr1 of the valve body 31 is circular, the distance Dgn1 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is different in the circumferential direction. That is, the distance Dgn1 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is not constant in the circumferential direction, and the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is a large portion (gap Sb01). ) And a small portion (gap Sb02) are formed (see FIG. 109). Thus, even when foreign matter in the cooling water in the internal space 200 enters the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211, the foreign matter moves to the large gap Sb01 by the rotation of the valve body 31. The foreign matter can be easily discharged from the gap Sb01. Therefore, it is possible to suppress the malfunction of the valve body 31 due to the foreign matter remaining in the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211. Further, an increase in load torque related to driving of the valve body 31 and an increase in pressure loss resistance can be suppressed.

　図１０８、１０９に示すように、弁体３１は、回転軸Ａｘｒ１から外周壁までの距離Ｄｇａ１が周方向で同じになるよう形成されている。つまり、弁体３１の外周壁は、回転軸Ａｘｒ１に垂直な断面において円形となるよう形成されている。 <10-2>
As shown in FIGS. 108 and 109, the valve body 31 is formed such that the distance Dga1 from the rotation axis Axr1 to the outer peripheral wall is the same in the circumferential direction. That is, the outer peripheral wall of the valve body 31 is formed to be circular in a cross section perpendicular to the rotation axis Axr1.
　そのため、上述のように、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１は、周方向で異なる。弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０は、周方向で大きな部分（隙間Ｓｂ０１）と小さな部分（隙間Ｓｂ０２）とが形成される。したがって、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０に異物が留まり続けることによる弁体３１の作動不良を抑制することができる。 Therefore, as described above, the distance Dgn1 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is different in the circumferential direction. In the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211, a large part (gap Sb01) and a small part (gap Sb02) are formed in the circumferential direction. Therefore, it is possible to suppress the malfunction of the valve body 31 due to the foreign matter remaining in the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211.
＜１０－３＞
　図１０８に示すように、ハウジング内壁２１１は、軸Ａｘｎ１に垂直な断面において非真円となるよう形成されている。 <10-3>
As shown in FIG. 108, the housing inner wall 211 is formed to be a non-circular circle in a cross section perpendicular to the axis Axn1.
　そのため、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０は、周方向で大きな部分（隙間Ｓｂ０１）と小さな部分（隙間Ｓｂ０２）とが形成される。 Therefore, the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is formed with a large part (gap Sb01) and a small part (gap Sb02) in the circumferential direction.
＜１０－４＞
　図１０８に示すように、ハウジング内壁２１１は、軸Ａｘｎ１に垂直な断面において多角形となるよう形成されている。 <10-4>
As shown in FIG. 108, the housing inner wall 211 is formed in a polygonal shape in a cross section perpendicular to the axis Axn1.
　そのため、ハウジング内壁２１１の断面を円形に近付けハウジング本体２１の径方向の体格を小さくしつつ、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０に周方向で大きな部分（隙間Ｓｂ０１）と小さな部分（隙間Ｓｂ０２）とを形成できる。 Therefore, the cross section of the housing inner wall 211 is made close to a circle, and the physique in the radial direction of the housing body 21 is made smaller, while a large portion in the circumferential direction (gap Sb01) is formed in the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211. And a small portion (gap Sb02) can be formed.
　なお、本実施形態では、ハウジング内壁２１１は、軸Ａｘｎ１に垂直な断面において八角形となるよう形成されている。また、断面八角形のハウジング内壁２１１の各辺の接続部分である角部２１４は、滑らかな曲線状になっている（図１０８、１０９参照）。 In the present embodiment, the housing inner wall 211 is formed in an octagonal shape in a cross section perpendicular to the axis Axn1. Further, the corner portion 214 which is a connecting portion of each side of the housing inner wall 211 having an octagonal cross section has a smooth curved shape (see FIGS. 108 and 109).
　そのため、ハウジング本体２１の径方向の体格をより小さくすることができる。また、ハウジング内壁２１１の角部２１４に異物が留まるのを抑制できる。 Therefore, the physique in the radial direction of the housing body 21 can be further reduced. Further, it is possible to suppress foreign matters from staying at the corners 214 of the housing inner wall 211.

　図６７に示すように、「弁体３１の外径が最も大きい部分を含み、かつ、ハウジング内壁２１１の軸Ａｘｎ１に垂直な断面（例えば図６７においてＰｄ１で示す面による断面）」において、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１は、周方向で異なる。 <10-5>
As shown in FIG. 67, in the “cross section including the portion having the largest outer diameter of the valve body 31 and perpendicular to the axis Axn1 of the housing inner wall 211 (for example, a cross section taken along the surface indicated by Pd1 in FIG. 67)” A distance Dgn1 between the outer peripheral wall 31 and the housing inner wall 211 differs in the circumferential direction.
　そのため、異物の影響が大きい「弁体３１の外径が最も大きい部分」において、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０から異物を排出できる。 Therefore, the foreign matter can be discharged from the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 in the “part where the outer diameter of the valve body 31 is the largest” where the influence of the foreign matter is large.

　図６７に示すように、「ハウジング内壁２１１のうちポート（２２０、２２１、２２２、２２３）が開口している部分以外の部分、および、弁体３１のうち弁体開口部（４１０、４２０、４３０）が形成されている部分以外の部分を含み、かつ、ハウジング内壁２１１の軸Ａｘｎ１に垂直な断面（例えば図６７においてＰｄ２で示す面による断面）」において、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１は、周方向で異なる。 <10-6>
As shown in FIG. 67, “a portion of the housing inner wall 211 other than the portion where the ports (220, 221, 222, 223) are open, and a valve body opening portion (410, 420, 430) of the valve body 31. ) And a section perpendicular to the axis Axn1 of the housing inner wall 211 (for example, a section taken along a plane indicated by Pd2 in FIG. 67) ”, the outer peripheral wall of the valve body 31 and the housing inner wall 211 Is different in the circumferential direction.
　そのため、異物の影響が大きい「弁体３１の周方向の全域にわたり閉塞された隙間Ｓｂ１０の部分」において、隙間Ｓｂ１０から異物を排出できる。 Therefore, the foreign matter can be discharged from the gap Sb10 in the “portion of the gap Sb10 closed over the entire circumferential direction of the valve body 31” where the influence of the foreign matter is large.

　図６８に示すように、ハウジング２０は、ハウジング内壁２１１に開口し内部空間２００とハウジング本体２１の外部とを接続するリリーフポート２２４を有している。 <10-7>
As shown in FIG. 68, the housing 20 has a relief port 224 that opens in the housing inner wall 211 and connects the internal space 200 and the outside of the housing body 21.
　本実施形態は、リリーフ弁３９をさらに備える。リリーフ弁３９は、リリーフポート２２４に設けられ、条件に応じてリリーフポート２２４を開閉する。 The present embodiment further includes a relief valve 39. The relief valve 39 is provided in the relief port 224, and opens and closes the relief port 224 according to conditions.
　冷却水の流れに沿って異物を除去できない状況では、内部空間２００に異物が溜まり、リリーフ弁３９が開いたときに、異物が挟まることでリリーフ弁３９が開いたままの状態になるおそれがある。 In a situation where foreign matter cannot be removed along the flow of cooling water, foreign matter may accumulate in the internal space 200, and when the relief valve 39 is opened, the relief valve 39 may remain open due to the foreign matter being caught. .
　そこで、本実施形態では、ハウジング内壁２１１を、軸Ａｘｎ１からの距離Ｄｎａ１が周方向で異なるよう形成すること等により、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１を周方向で異なるようにし、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０から異物を容易に排出できるようにしている。これにより、リリーフ弁３９に異物が挟まりリリーフ弁３９が開いたままの状態になるのを抑制できる。 Thus, in the present embodiment, the distance Dgn1 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is made different in the circumferential direction by forming the housing inner wall 211 such that the distance Dna1 from the axis Axn1 is different in the circumferential direction. In addition, foreign matter can be easily discharged from the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211. Thereby, it can suppress that a foreign material is pinched | interposed into the relief valve 39, and the relief valve 39 will be in the open state.

As shown in FIG. 67, the present embodiment further includes a valve seal 36. The valve seal 36 is formed in an annular shape, is provided at a position corresponding to the ports (221, 222, 223) so as to be slidable with the outer peripheral wall of the valve body 31, and is liquid-tight between the outer peripheral wall of the valve body 31.

　「バルブシール３６を含み、かつ、ハウジング内壁２１１の軸Ａｘｎ１に垂直な断面（例えば図６７においてＰｄ１で示す面による断面）」において、弁体３１の外周壁とハウジング内壁２１１との距離Ｄｇｎ１は、周方向で異なる。 In a “cross section including the valve seal 36 and perpendicular to the axis Axn1 of the housing inner wall 211 (for example, a section taken along the surface indicated by Pd1 in FIG. 67)”, the distance Dgn1 between the outer peripheral wall of the valve body 31 and the housing inner wall 211 is Different in the circumferential direction.
　そのため、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０におけるバルブシール３６の周囲から異物を除去することができる。これにより、弁体３１の外周壁とバルブシール３６との間に異物が挟み込まれることによる弁体３１の外周壁の損傷を抑制できる。 Therefore, foreign matter can be removed from the periphery of the valve seal 36 in the gap Sb10 between the outer peripheral wall of the valve body 31 and the housing inner wall 211. Thereby, damage to the outer peripheral wall of the valve body 31 due to foreign matter being sandwiched between the outer peripheral wall of the valve body 31 and the valve seal 36 can be suppressed.

The sealing property between the housing opening 210 and the partition wall body 61 can be secured while facilitating the removal of foreign matter from the gap Sb10.
　本実施形態では、弁体３１は内周壁および外周壁が球面状のボールバルブ４１、４２、４３を含む。これに対し、他の実施形態では、弁体３１は、例えば円筒状に形成されていてもよい。この場合でも、ハウジング内壁２１１等を上述のように形成することにより、弁体３１の外周壁とハウジング内壁２１１との間の隙間Ｓｂ１０から異物を容易に除去することができる。 In the present embodiment, the valve body 31 includes ball valves 41, 42, and 43 whose inner peripheral wall and outer peripheral wall are spherical. On the other hand, in other embodiments, the valve body 31 may be formed in a cylindrical shape, for example.

＜１１－１＞リリーフ弁遮蔽部
　本実施形態は、車両１のエンジン２の冷却水を制御可能なバルブ装置１０であって、ハウジング２０とバルブ３０とリリーフ弁３９と遮蔽部９５とを備える。 <11-1> Relief Valve Shielding Section This embodiment is a valve device 10 that can control the cooling water of the engine 2 of the vehicle 1, and includes a housing 20, a valve 30, a relief valve 39, and a shielding section 95.
　ハウジング２０は、内側に内部空間２００を形成するハウジング本体２１、内部空間２００とハウジング本体２１の外部とを接続し冷却水が流入する入口ポート２２０、および、内部空間２００とハウジング本体２１の外部とを接続するリリーフポート２２４を有する。 The housing 20 includes a housing main body 21 that forms an internal space 200 inside, an inlet port 220 that connects the internal space 200 and the outside of the housing main body 21 and into which cooling water flows, and an internal space 200 and the outside of the housing main body 21. Has a relief port 224 for connecting the two.
　バルブ３０は、内部空間２００内において回転軸Ａｘｒ１周りに回転可能な弁体３１、および、回転軸Ａｘｒ１に設けられたシャフト３２を有する。 The valve 30 has a valve body 31 that can rotate around the rotation axis Axr1 in the internal space 200, and a shaft 32 provided on the rotation axis Axr1.
　リリーフ弁３９は、リリーフポート２２４に設けられ、条件に応じて開弁または閉弁し、リリーフポート２２４を経由した内部空間２００とハウジング本体２１の外部との連通を許容または遮断する。 The relief valve 39 is provided in the relief port 224, and opens or closes depending on the conditions, and allows or blocks communication between the internal space 200 and the outside of the housing body 21 via the relief port 224.
　ここで、リリーフ弁３９の開弁条件は、例えば「周囲の温度が所定の温度以上になったとき」である。リリーフ弁３９は、例えば冷却水の温度が所定の温度以上となったとき、開弁し、リリーフポート２２４を経由した内部空間２００とハウジング本体２１の外部すなわちパイプ部５１５の内側の空間との連通を許容し、冷却水の温度が所定の温度より低くなったとき、上記連通を遮断する。これにより、車両１のオーバーヒート時等、冷却水の温度が過度に上昇した場合、冷却水を内部空間２００から外部のラジエータ５へ流し、冷却水を冷却することができる。 Here, the opening condition of the relief valve 39 is, for example, “when the ambient temperature becomes equal to or higher than a predetermined temperature”. The relief valve 39 opens, for example, when the temperature of the cooling water becomes equal to or higher than a predetermined temperature, and communicates between the internal space 200 via the relief port 224 and the space outside the housing body 21, that is, the space inside the pipe portion 515. And the communication is cut off when the temperature of the cooling water is lower than a predetermined temperature. Thereby, when the temperature of the cooling water rises excessively, such as when the vehicle 1 is overheated, the cooling water can be flowed from the internal space 200 to the external radiator 5 to cool the cooling water.
　図１１２に示すように、遮蔽部９５は、入口ポート２２０からリリーフ弁３９が目視できないようリリーフ弁３９を遮蔽可能である。より具体的には、リリーフ弁３９は、入口ポート２２０の軸方向から見たとき、遮蔽部９５によって遮蔽され、全体が目視不能である。 112, the shielding portion 95 can shield the relief valve 39 so that the relief valve 39 cannot be seen from the inlet port 220. More specifically, when viewed from the axial direction of the inlet port 220, the relief valve 39 is shielded by the shielding portion 95 and cannot be visually observed as a whole.
　そのため、入口ポート２２０から内部空間２００に流入した冷却水がリリーフ弁３９に直撃するのを抑制することができる。これにより、瞬間的に温度の高い冷却水が流入したとき、または、局所的に温度の高い冷却水が流入したときでも、リリーフ弁３９がオーバーヒートと誤認し誤作動により開弁するのを抑制することができる。したがって、リリーフ弁３９により、車両１のオーバーヒートを適切に抑制可能である。 Therefore, it is possible to suppress the cooling water flowing into the internal space 200 from the inlet port 220 from hitting the relief valve 39 directly. This prevents the relief valve 39 from being erroneously recognized as overheating and being opened due to a malfunction even when high-temperature cooling water flows in instantaneously or even when high-temperature cooling water flows locally. be able to. Therefore, the relief valve 39 can appropriately suppress overheating of the vehicle 1.

　図１１２に示すように、遮蔽部９５は、シャフト３２に対しリリーフポート２２４側に位置するようハウジング本体２１に設けられている。 <11-2>
As shown in FIG. 112, the shielding portion 95 is provided in the housing body 21 so as to be positioned on the relief port 224 side with respect to the shaft 32.
　そのため、遮蔽部９５をリリーフ弁３９に近付けて配置でき、リリーフ弁３９への冷却水の直撃をより効果的に抑制できる。 Therefore, the shielding part 95 can be disposed close to the relief valve 39, and the direct hit of the cooling water to the relief valve 39 can be more effectively suppressed.

As shown in FIGS. 110 and 112, the shielding portion 95 is formed by projecting the inlet port 220 when the inlet port 220, the relief valve 39 and the shielding portion 95 are projected in the axial direction of the inlet port 220 or the axial direction of the relief port 224. The projection is formed so as to have an area that is equal to or larger than the area of the portion B1 (the portion indicated by the lattice in FIG. 110) where the projection of the relief valve 39 overlaps.
　そのため、リリーフ弁３９への冷却水の直撃を確実に防ぎつつ、必要以上に流路面積を絞らないことで通水性を確保できる。 Therefore, it is possible to ensure water permeability by preventing the cooling water from directly hitting the relief valve 39 and not reducing the flow area more than necessary.

　本実施形態は、車両１のエンジン２の冷却水を制御可能なバルブ装置１０であって、ハウジング２０とバルブ３０と駆動部７０と制御部としてのＥＣＵ８とを備える。 <12-1> Flow Diagram This embodiment is a valve device 10 that can control the cooling water of the engine 2 of the vehicle 1 and includes a housing 20, a valve 30, a drive unit 70, and an ECU 8 as a control unit.
　ハウジング２０は、内部空間２００、内部空間２００に接続し車両１のラジエータ５に接続されるラジエータポートとしての出口ポート２２１、内部空間２００に接続し車両１のヒータ６に接続されるヒータポートとしての出口ポート２２２、および、内部空間２００に接続し車両１のデバイス７に接続されるデバイスポートとしての出口ポート２２３を有する。以下、簡単のため、適宜、出口ポート２２１、２２２、２２３を、それぞれ、ラジエータポート２２１、ヒータポート２２２、デバイスポート２２３と読み替える。 The housing 20 is connected to the internal space 200, the outlet port 221 as a radiator port connected to the radiator 5 of the vehicle 1, and the heater port connected to the heater 6 of the vehicle 1 connected to the internal space 200.

　バルブ３０は、内部空間２００内において回転軸Ａｘｒ１周りに回転可能な弁体３１を有し、弁体３１の回転位置によりラジエータポート２２１、ヒータポート２２２またはデバイスポート２２３を開閉可能である。 The valve 30 has a valve body 31 that can rotate around the rotation axis Axr1 in the internal space 200, and can open and close the radiator port 221, the heater port 222, or the device port 223 according to the rotational position of the valve body 31.
　駆動部７０は、弁体３１を回転駆動可能である。 The driving unit 70 can drive the valve body 31 to rotate.
　ＥＣＵ８は、駆動部７０の作動を制御し弁体３１の回転駆動を制御することで、ラジエータポート２２１とラジエータ５との間、ヒータポート２２２とヒータ６との間、および、デバイスポート２２３とデバイス７との間の冷却水の流れを制御可能である。 The ECU 8 controls the operation of the drive unit 70 to control the rotational drive of the valve body 31, so that between the radiator port 221 and the radiator 5, between the heater port 222 and the heater 6, and between the device port 223 and the device The flow of the cooling water between 7 can be controlled.

As shown in FIGS. 113 and 114, as the valve body 31 is driven to rotate in one direction of rotation, the ECU 8 has all the opening degrees of the radiator port 221, the heater port 222, and the device port 223 at the predetermined opening degree. After that, the drive unit 70 and the valve body 31 can be controlled so that the heater port 222 and the device port 223 are closed in the order of the heater port 222 and the device port 223.

A valve body opening 410 serving as a radiator opening, where the polymerization ratio of the radiator, which is a polymerization ratio, is formed so as to connect the outer peripheral wall and the inner peripheral wall of the valve body 31.

It has the valve body opening part 430 as an opening part for devices from which the device superposition | polymerization rate which is a superposition | polymerization rate changes.

When the radiator polymerization rate is greater than 0, the radiator port 221 is opened, and the valve body flow path 300 and the radiator 5 communicate with each other via the radiator opening 410 and the radiator port 221. Thereby, at this time, the cooling water flows from the valve body flow path 300 to the radiator 5 side.

Thereby, at this time, cooling water flows from the valve body flow path 300 to the device 7 side.
　次に、本実施形態のバルブ装置１０における冷却水のフローダイアグラムについて、図１１３、１１４に基づき詳細に説明する。 Next, a flow diagram of the cooling water in the valve device 10 of the present embodiment will be described in detail based on FIGS.
　図１１３、１１４に示すように、弁体３１の回転位置が基準位置である０（度）のとき（図１１４における回転位置Ｐｒ０のとき）、すなわち、第１規制凸部３３２または第２規制凸部３４２の一方が規制部６３１に当接し弁体３１の回転が規制されているとき、ラジエータポート２２１、ヒータポート２２２、デバイスポート２２３の開度は、いずれも、０％（全閉）である。以下、Ｐｒ０～１３と記載した場合、図１１４における回転位置Ｐｒ０～１３を意味する。 As shown in FIGS. 113 and 114, when the rotational position of the valve body 31 is 0 (degrees), which is the reference position (in the rotational position Pr0 in FIG. 114), that is, the first restricting protrusion 332 or the second restricting protrusion. When one of the portions 342 contacts the restricting portion 631 and the rotation of the valve body 31 is restricted, the opening degrees of the radiator port 221, the heater port 222, and the device port 223 are all 0% (fully closed). . Hereinafter, Pr0 to 13 mean the rotational positions Pr0 to Pr13 in FIG.
　ＥＣＵ８による駆動部７０の制御によって、弁体３１が回転方向の一方側に回転駆動し、弁体３１の回転位置が０から大きくなると、Ｐｒ２とＰｒ３との間で、ヒータポート２２２の開度が０（％）から所定の割合で増大する。これにより、ヒータポート２２２の開度に応じた量の冷却水がヒータ６側に流れる。ヒータポート２２２の開度は、Ｐｒ３で１００％（全開：前記所定開度）に達する。 When the valve body 31 is rotationally driven to one side in the rotational direction by the control of the drive unit 70 by the ECU 8, and the rotational position of the valve body 31 increases from 0, the opening degree of the heater port 222 is between Pr2 and Pr3. It increases at a predetermined rate from 0 (%). Thereby, an amount of cooling water corresponding to the opening degree of the heater port 222 flows to the heater 6 side. The opening degree of the heater port 222 reaches 100% at Pr3 (fully open: the predetermined opening degree).
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ４とＰｒ５との間で、デバイスポート２２３の開度が０（％）から所定の割合で増大する。これにより、デバイスポート２２３の開度に応じた量の冷却水がデバイス７側に流れる。デバイスポート２２３の開度は、Ｐｒ５で１００％（全開：前記所定開度）に達する。 When the valve body 31 is further rotated to one side in the rotation direction, the opening degree of the device port 223 increases from 0 (%) to a predetermined rate between Pr4 and Pr5. Thereby, an amount of cooling water corresponding to the opening degree of the device port 223 flows to the device 7 side. The opening degree of the device port 223 reaches 100% (full open: the predetermined opening degree) at Pr5.
　ここで、弁体３１の単位回転角度当りのＰｒ２とＰｒ３との間におけるヒータポート２２２の開度の増大割合は、Ｐｒ４とＰｒ５との間におけるデバイスポート２２３の開度の増大割合と同じである（図１１３、１１４参照）。 Here, the increasing rate of the opening degree of the heater port 222 between Pr2 and Pr3 per unit rotation angle of the valve body 31 is the same as the increasing rate of the opening degree of the device port 223 between Pr4 and Pr5. (See FIGS. 113 and 114).
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ６とＰｒ７との間で、ラジエータポート２２１の開度が０（％）から所定の割合で増大する。これにより、ラジエータポート２２１の開度に応じた量の冷却水がラジエータ５側に流れる。 When the valve body 31 is further rotated to one side in the rotational direction, the opening degree of the radiator port 221 increases from 0 (%) at a predetermined rate between Pr6 and Pr7. Thereby, an amount of cooling water corresponding to the opening degree of the radiator port 221 flows to the radiator 5 side.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ７とＰｒ８との間で、ラジエータポート２２１の開度が所定の割合でさらに増大する。ラジエータポート２２１の開度は、Ｐｒ８で１００％（全開：前記所定開度）に達する。そのため、Ｐｒ８において、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度が前記所定開度すなわち１００％になる。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the radiator port 221 further increases at a predetermined rate between Pr7 and Pr8. The opening degree of the radiator port 221 reaches 100% (full opening: the predetermined opening degree) at Pr8. Therefore, in Pr8, all the openings of the radiator port 221, the heater port 222, and the device port 223 become the predetermined opening, that is, 100%.
　ここで、弁体３１の単位回転角度当りのＰｒ６とＰｒ７との間におけるラジエータポート２２１の開度の増大割合は、Ｐｒ７とＰｒ８との間におけるラジエータポート２２１の開度の増大割合より小さい（図１１３、１１４参照）。これは、ラジエータ用開口部４１０が延伸開口部４１３と大開口部４１２とから形成されていることによる（図９３、９４等参照）。つまり、ラジエータポート２２１の開度の増大割合は、延伸開口部４１３とシール開口部３６０とが重なるとき小さく、大開口部４１２とシール開口部３６０とが重なるとき大きくなる。 Here, the increase rate of the opening of the radiator port 221 between Pr6 and Pr7 per unit rotation angle of the valve body 31 is smaller than the increase rate of the opening of the radiator port 221 between Pr7 and Pr8 (FIG. 113, 114). This is because the radiator opening 410 is formed of the extended opening 413 and the large opening 412 (see FIGS. 93 and 94). That is, the increasing rate of the opening of the radiator port 221 is small when the extending opening 413 and the seal opening 360 are overlapped, and is increased when the large opening 412 and the seal opening 360 are overlapped.
　そのため、ラジエータポート２２１の開弁初期において、ラジエータ５への冷却水の流量を徐々に大きくすることができる。これにより、ラジエータ５の熱交換による冷却水の急激な温度変化を抑制することができる。 Therefore, at the initial opening of the radiator port 221, the flow rate of the cooling water to the radiator 5 can be gradually increased. Thereby, the rapid temperature change of the cooling water by the heat exchange of the radiator 5 can be suppressed.
　また、弁体３１の単位回転角度当りのＰｒ６とＰｒ７との間におけるラジエータポート２２１の開度の増大割合、および、Ｐｒ７とＰｒ８との間におけるラジエータポート２２１の開度の増大割合は、Ｐｒ２とＰｒ３との間におけるヒータポート２２２の開度の増大割合、Ｐｒ４とＰｒ５との間におけるデバイスポート２２３の開度の増大割合より小さい（図１１３、１１４参照）。 Further, the increase rate of the opening degree of the radiator port 221 between Pr6 and Pr7 per unit rotation angle of the valve body 31 and the increase rate of the opening degree of the radiator port 221 between Pr7 and Pr8 are Pr2 and Pr2. The rate of increase in the opening degree of the heater port 222 with respect to Pr3 is smaller than the rate of increase in the opening degree of the device port 223 between Pr4 and Pr5 (see FIGS. 113 and 114).
　そのため、開弁初期におけるラジエータ５への冷却水の流量変化を、ヒータ６、デバイス７への冷却水の流量変化と比べ、緩やかにすることができる。これにより、ラジエータ５の熱交換による冷却水の急激な温度変化を抑制することができる。 Therefore, the change in the flow rate of the cooling water to the radiator 5 at the initial stage of the valve opening can be made slower than the change in the flow rate of the cooling water to the heater 6 and the device 7. Thereby, the rapid temperature change of the cooling water by the heat exchange of the radiator 5 can be suppressed.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ９とＰｒ１０との間で、ヒータポート２２２の開度が１００％から所定の割合で減少する。これにより、ヒータ６側に流れる冷却水の量がヒータポート２２２の開度に応じて減少する。ヒータポート２２２の開度は、Ｐｒ１０で０％（全閉）になる。これにより、ヒータポート２２２が閉じ、ヒータ６側への冷却水の流れが遮断される。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the heater port 222 is decreased from 100% to a predetermined ratio between Pr9 and Pr10. As a result, the amount of cooling water flowing to the heater 6 side decreases according to the opening degree of the heater port 222. The opening degree of the heater port 222 is 0% (fully closed) at Pr10. Thereby, the heater port 222 is closed and the flow of the cooling water to the heater 6 side is interrupted.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ１１とＰｒ１２との間で、デバイスポート２２３の開度が１００％から所定の割合で減少する。これにより、デバイス７側に流れる冷却水の量がデバイスポート２２３の開度に応じて減少する。デバイスポート２２３の開度は、Ｐｒ１２で０％（全閉）になる。これにより、デバイスポート２２３が閉じ、デバイス７側への冷却水の流れが遮断される。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the device port 223 decreases between 100% and Pr12 at a predetermined rate between Pr11 and Pr12. As a result, the amount of cooling water flowing to the device 7 side decreases according to the opening degree of the device port 223. The opening degree of the device port 223 becomes 0% (fully closed) at Pr12. Thereby, the device port 223 is closed and the flow of the cooling water to the device 7 side is blocked.
　ここで、弁体３１の単位回転角度当りのＰｒ９とＰｒ１０との間におけるヒータポート２２２の開度の減少割合は、Ｐｒ１１とＰｒ１２との間におけるデバイスポート２２３の開度の減少割合と同じである（図１１３、１１４参照）。 Here, the decreasing rate of the opening degree of the heater port 222 between Pr9 and Pr10 per unit rotation angle of the valve body 31 is the same as the decreasing rate of the opening degree of the device port 223 between Pr11 and Pr12. (See FIGS. 113 and 114).
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ１３で、第１規制凸部３３２または第２規制凸部３４２の他方が規制部６３１に当接し、弁体３１の回転駆動が停止する。このとき、ラジエータポート２２１の開度は、１００％のままである。すなわち、このとき、ラジエータポート２２１のみ開度が１００％（全開：前記所定開度）になっている。 When the valve body 31 is further rotationally driven to one side in the rotation direction, at Pr13, the other of the first restriction convex part 332 or the second restriction convex part 342 contacts the restriction part 631, and the rotational drive of the valve body 31 stops. . At this time, the opening degree of the radiator port 221 remains 100%. That is, at this time, only the radiator port 221 has an opening degree of 100% (fully open: the predetermined opening degree).
　本実施形態では、上述のように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ８で前記所定開度（１００％）になった後、Ｐｒ１０、Ｐｒ１２でヒータポート２２２およびデバイスポート２２３が閉じ、Ｐｒ１３でラジエータポート２２１のみ開度が前記所定開度（１００％）になるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, as the valve body 31 is rotationally driven to one side in the rotational direction, the ECU 8 is configured such that all the opening degrees of the radiator port 221, the heater port 222, and the device port 223 are Pr8. After reaching the degree (100%), the heater port 222 and the device port 223 are closed by Pr10 and Pr12, and the opening of only the radiator port 221 is set to the predetermined opening (100%) at Pr13 and the valve body 70 31 can be controlled.
　また、本実施形態では、上述のように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ８で前記所定開度（１００％）になった後、ヒータポート２２２およびデバイスポート２２３がヒータポート２２２、デバイスポート２２３の順（Ｐｒ１０、Ｐｒ１２）で閉じるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, the ECU 8 is configured such that the opening degree of the radiator port 221, the heater port 222, and the device port 223 is Pr8 as the valve body 31 is rotationally driven to one side in the rotational direction. After reaching the predetermined opening (100%), the drive unit 70 and the valve body 31 can be controlled so that the heater port 222 and the device port 223 are closed in the order of the heater port 222 and the device port 223 (Pr10, Pr12).
　　（第１６実施形態）
　第１６実施形態によるバルブ装置を図１１５に示す。第１６実施形態は、締結部２３１～２３３の形状等が第１４実施形態と異なる。 (Sixteenth embodiment)
FIG. 115 shows a valve device according to the sixteenth embodiment. The sixteenth embodiment differs from the fourteenth embodiment in the shapes of the fastening portions 231 to 233.
＜１－１１＞
　締結部２３１は、締結穴２４１に垂直な面による断面における形状が直線状となる２つの外壁（２３４、２３５）を有し、当該２つの外壁（２３４、２３５）の成す角θ１が鈍角となるよう形成されている。 <1-11>
The fastening portion 231 has two outer walls (234, 235) in which the shape in a section perpendicular to the fastening hole 241 is linear, and an angle θ1 formed by the two outer walls (234, 235) is an obtuse angle. It is formed as follows.
　締結部２３２は、締結穴２４２に垂直な面による断面における形状が直線状となる２つの外壁（２３６、２３７）を有し、当該２つの外壁（２３６、２３７）の成す角θ２が鈍角となるよう形成されている。 The fastening portion 232 has two outer walls (236, 237) that are linear in cross section by a plane perpendicular to the fastening hole 242, and an angle θ2 formed by the two outer walls (236, 237) is an obtuse angle. It is formed as follows.
　締結部２３３は、締結穴２４３に垂直な面による断面における形状が直線状となる２つの外壁（２３８、２３９）を有し、当該２つの外壁（２３８、２３９）の成す角θ３が鈍角となるよう形成されている。 The fastening portion 233 has two outer walls (238, 239) in which the shape in a section perpendicular to the fastening hole 243 is linear, and an angle θ3 formed by the two outer walls (238, 239) is an obtuse angle. It is formed as follows.
　そのため、締結部２３１～２３３の強度を向上でき、バルブ装置１０の耐震性を向上できる。なお、バルブ装置１０は、使用時、内部空間２００に冷却水が流入するため、冷却水を含む装置の重量が比較的大きくなる。そのため、締結部２３１～２３３の強度を向上することにより、限られた搭載スペース（狭小空間Ａ１）においてバルブ装置１０を確実に固定できる。 Therefore, the strength of the fastening portions 231 to 233 can be improved, and the earthquake resistance of the valve device 10 can be improved. In addition, since the cooling water flows into the internal space 200 when the valve device 10 is used, the weight of the device including the cooling water becomes relatively large. Therefore, by improving the strength of the fastening portions 231 to 233, the valve device 10 can be reliably fixed in a limited mounting space (narrow space A1).
　図１１５に示すように、弁体３１の回転軸Ａｘｒ１方向において、締結部２３１が形成されている範囲は、締結部２３２と締結部２３３が形成されている範囲と重複している。 115, in the direction of the rotation axis Axr1 of the valve body 31, the range in which the fastening portion 231 is formed overlaps with the range in which the fastening portion 232 and the fastening portion 233 are formed.
　そのため、ハウジング本体２１をエンジン２に安定して固定できる。 Therefore, the housing body 21 can be stably fixed to the engine 2.
　弁体３１の回転軸Ａｘｒ１方向における締結部２３１、２３２、２３３の長さは、入口ポート２２０の直径より大きい。 The lengths of the fastening portions 231, 232, 233 in the direction of the rotation axis Axr 1 of the valve body 31 are larger than the diameter of the inlet port 220.
　そのため、ハウジング本体２１をエンジン２に安定して固定できる。 Therefore, the housing body 21 can be stably fixed to the engine 2.
　弁体３１の回転軸Ａｘｒ１方向における締結部２３１の長さは、弁体３１の回転軸Ａｘｒ１方向における締結部２３２または締結部２３３の長さより大きい。 The length of the fastening portion 231 in the direction of the rotation axis Axr1 of the valve body 31 is larger than the length of the fastening portion 232 or the fastening portion 233 in the direction of the rotation axis Axr1 of the valve body 31.
　そのため、３つの締結部のうち１つしかない側について、ハウジング本体２１をエンジン２に固定したときのハウジング本体２１の左右両方向（幅方向）のバランスを確保できる。 Therefore, it is possible to secure a balance in the left and right directions (width direction) of the housing body 21 when the housing body 21 is fixed to the engine 2 on the side where only one of the three fastening portions is provided.
　弁体３１の回転軸Ａｘｒ１方向における締結部２３１の中心、および、弁体３１の回転軸Ａｘｒ１方向における締結部２３３の中心は、入口ポート２２０の中心より駆動部７０側にある。 The center of the fastening portion 231 in the direction of the rotational axis Axr1 of the valve body 31 and the center of the fastening portion 233 in the direction of the rotational axis Axr1 of the valve body 31 are closer to the drive portion 70 than the center of the inlet port 220.
　そのため、駆動部７０による振動を効果的に抑制できる。 Therefore, vibrations by the drive unit 70 can be effectively suppressed.
　締結部２３３の外壁２３８の駆動部７０側の端部は、外壁２３９の入口ポート２２０側の端部に対し回転軸Ａｘｒ１とは反対側に位置している。 The end of the outer wall 238 of the fastening portion 233 on the drive unit 70 side is located on the opposite side of the rotation axis Axr1 with respect to the end of the outer wall 239 on the inlet port 220 side.
　そのため、駆動部７０による振動を効果的に抑制できる。 Therefore, vibrations by the drive unit 70 can be effectively suppressed.
　締結部２３２、２３３は、取付面２０１のうち取付面凹部２０７が形成された範囲の弁体３１の回転軸Ａｘｒ１方向の一端から他端にわたり形成されている。 The fastening portions 232 and 233 are formed from one end to the other end in the direction of the rotation axis Axr1 of the valve body 31 in a range in which the mounting surface recess 207 is formed in the mounting surface 201.
　そのため、ハウジング本体２１をエンジン２に安定して固定できる。 Therefore, the housing body 21 can be stably fixed to the engine 2.

＜３－３０＞
　隔壁部６０は、内部空間２００とハウジング２０の外部とを隔てる隔壁部本体６１、シャフト３２の一端を挿通可能なよう隔壁部本体６１に形成されたシャフト挿通穴６２、および、隔壁部本体６１の内部空間２００側の面から内部空間２００とは反対側へ凹む規制凹部６３を有する。 <3-30>
The partition wall 60 includes a partition wall body 61 that separates the internal space 200 from the outside of the housing 20, a shaft insertion hole 62 formed in the partition wall body 61 so that one end of the shaft 32 can be inserted, and the partition wall body 61. A regulating recess 63 that is recessed from the surface on the inner space 200 side to the side opposite to the inner space 200 is provided.
　弁体３１は、第２分割体３４の隔壁部６０側の面である第１最外端面３０１から規制凹部６３側へ延びて先端部が規制凹部６３に位置する規制凸部３４４を有している。 The valve body 31 has a regulation convex part 344 that extends from the first outermost end surface 301 that is the surface of the second divided body 34 on the partition wall part 60 side to the regulation concave part 63 side and whose tip part is located in the regulation concave part 63.

On the other hand, in the present embodiment, as described above, one restriction convex portion 344 is formed so as to extend from the second divided body 34.
　本実施形態においても、規制部６３１により弁体３１の回転を規制するとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れる（剥離する）方向の力が弁体３１に作用するのを抑制できる。そのため、規制凸部３４４が規制凹部６３の規制部６３１に当接したとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れるのを抑制できる。 Also in the present embodiment, when the rotation of the valve body 31 is restricted by the restriction portion 631, the force in the direction in which the first divided body 33 and the second divided body 34 are separated (separated) at the joint surfaces 331 and 341 is the valve body. It can suppress acting on 31. Therefore, when the restricting convex portion 344 comes into contact with the restricting portion 631 of the restricting concave portion 63, it is possible to suppress the first divided body 33 and the second divided body 34 from being separated by the joint surfaces 331 and 341.
　本実施形態では、規制凸部３４４は、「回転軸Ａｘｒ１を含み接合面３３１、３４１に垂直な仮想平面Ｖｐ８」上に形成されている（図１１６参照）。 In the present embodiment, the restricting convex portion 344 is formed on the “virtual plane Vp8 including the rotation axis Axr1 and perpendicular to the joint surfaces 331 and 341” (see FIG. 116).
　そのため、規制部６３１により弁体３１の回転を規制するとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れる（剥離する）方向の力が弁体３１に作用するのを確実に抑制できる。 Therefore, when the rotation of the valve body 31 is restricted by the restriction portion 631, a force in a direction in which the first divided body 33 and the second divided body 34 are separated (separated) at the joint surfaces 331 and 341 acts on the valve body 31.

The first restriction convex portion 332 extends toward the restriction concave portion 63 along the surface direction of the joint surface 331. The second restriction convex part 342 extends toward the restriction concave part 63 along the surface direction of the joint surface 341 without contacting the first restriction convex part 332.
　本実施形態においても、第３実施形態と同様、規制部６３１により弁体３１の回転を規制するとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れる（剥離する）方向の力は作用しない。そのため、第１規制凸部３３２または第２規制凸部３４２が規制凹部６３の規制部６３１に当接したとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れるのを抑制できる。 Also in the present embodiment, as in the third embodiment, when the rotation of the valve body 31 is restricted by the restricting portion 631, the first divided body 33 and the second divided body 34 are separated (separated) at the joint surfaces 331 and 341. ) Directional force does not work. Therefore, when the first restriction convex part 332 or the second restriction convex part 342 comes into contact with the restriction part 631 of the restriction concave part 63, the first divided body 33 and the second divided body 34 are separated by the joint surfaces 331 and 341. Can be suppressed.
　本実施形態では、「回転軸Ａｘｒ１を含み接合面３３１、３４１に垂直な仮想平面Ｖｐ８」で弁体３１を２つの領域に分けたとき、第１規制凸部３３２および第２規制凸部３４２は、２つの領域の一方側に形成されている（図１１７参照）。 In the present embodiment, when the valve body 31 is divided into two regions on the “virtual plane Vp8 including the rotation axis Axr1 and perpendicular to the joint surfaces 331 and 341”, the first restriction convex part 332 and the second restriction convex part 342 are It is formed on one side of the two regions (see FIG. 117).
　そのため、規制部６３１により弁体３１の回転を規制するとき、第１分割体３３と第２分割体３４とが接合面３３１、３４１で離れる（剥離する）方向の力が弁体３１に作用するのを確実に抑制できる。 Therefore, when the rotation of the valve body 31 is restricted by the restriction portion 631, a force in a direction in which the first divided body 33 and the second divided body 34 are separated (separated) at the joint surfaces 331 and 341 acts on the valve body 31. Can be reliably suppressed.
　また、回転軸Ａｘｒ１と第１規制凸部３３２との距離は、回転軸Ａｘｒ１と第２規制凸部３４２との距離より小さい（図１１７参照）。 Further, the distance between the rotation axis Axr1 and the first restriction convex part 332 is smaller than the distance between the rotation axis Axr1 and the second restriction convex part 342 (see FIG. 117).

　図１２２に示すように、弁体３１の回転位置が基準位置である０のとき（図１２２における回転位置Ｐｒ０のとき）、すなわち、第１規制凸部３３２または第２規制凸部３４２の一方が規制部６３１に当接し弁体３１の回転が規制されているとき、ラジエータポート２２１、ヒータポート２２２、デバイスポート２２３の開度は、いずれも、０％（全閉）である。以下、Ｐｒ０～１３と記載した場合、図１２２における回転位置Ｐｒ０～１３を意味する。 As shown in FIG. 122, when the rotational position of the valve body 31 is 0, which is the reference position (when the rotational position Pr0 in FIG. 122), that is, one of the first restriction convex part 332 or the second restriction convex part 342 is When the rotation of the valve body 31 is restricted by contacting the restricting portion 631, the opening degrees of the radiator port 221, the heater port 222, and the device port 223 are all 0% (fully closed). Hereinafter, when described as Pr0 to 13, it means rotational positions Pr0 to Pr13 in FIG.
　弁体３１の回転に伴うラジエータポート２２１、ヒータポート２２２、デバイスポート２２３の開度の変化の仕方は、弁体３１の回転位置がＰｒ０～８までは、第１５実施形態と同様のため、説明を省略する。 The way of changing the opening degree of the radiator port 221, the heater port 222, and the device port 223 according to the rotation of the valve body 31 is the same as that of the fifteenth embodiment when the rotational position of the valve body 31 is Pr0 to Pr8. Is omitted.
　弁体３１がＰｒ８から回転方向の一方側にさらに回転駆動すると、Ｐｒ９とＰｒ１０との間で、デバイスポート２２３の開度が１００％から所定の割合で減少する。これにより、デバイス７側に流れる冷却水の量がデバイスポート２２３の開度に応じて減少する。デバイスポート２２３の開度は、Ｐｒ１０で０％（全閉）になる。これにより、デバイスポート２２３が閉じ、デバイス７側への冷却水の流れが遮断される。 When the valve body 31 is further rotationally driven from Pr8 to one side in the rotational direction, the opening degree of the device port 223 decreases at a predetermined rate from 100% between Pr9 and Pr10. As a result, the amount of cooling water flowing to the device 7 side decreases according to the opening degree of the device port 223. The opening degree of the device port 223 becomes 0% (fully closed) at Pr10. Thereby, the device port 223 is closed and the flow of the cooling water to the device 7 side is blocked.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ１１とＰｒ１２との間で、ヒータポート２２２の開度が１００％から所定の割合で減少する。これにより、ヒータ６側に流れる冷却水の量がヒータポート２２２の開度に応じて減少する。ヒータポート２２２の開度は、Ｐｒ１２で０％（全閉）になる。これにより、ヒータポート２２２が閉じ、ヒータ６側への冷却水の流れが遮断される。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the heater port 222 decreases at a predetermined rate from 100% between Pr11 and Pr12. As a result, the amount of cooling water flowing to the heater 6 side decreases according to the opening degree of the heater port 222. The opening degree of the heater port 222 is 0% (fully closed) at Pr12. Thereby, the heater port 222 is closed and the flow of the cooling water to the heater 6 side is interrupted.
　ここで、弁体３１の単位回転角度当りのＰｒ９とＰｒ１０との間におけるデバイスポート２２３の開度の減少割合は、Ｐｒ１１とＰｒ１２との間におけるヒータポート２２２の開度の減少割合と同じである。 Here, the decreasing rate of the opening degree of the device port 223 between Pr9 and Pr10 per unit rotation angle of the valve body 31 is the same as the decreasing rate of the opening degree of the heater port 222 between Pr11 and Pr12. .
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ１３で、第１規制凸部３３２または第２規制凸部３４２の他方が規制部６３１に当接し、弁体３１の回転駆動が停止する。このとき、ラジエータポート２２１の開度は、１００％のままである。すなわち、このとき、ラジエータポート２２１のみ開度が１００％（全開：前記所定開度）になっている。 When the valve body 31 is further rotationally driven to one side in the rotation direction, at Pr13, the other of the first restriction convex part 332 or the second restriction convex part 342 contacts the restriction part 631, and the rotational drive of the valve body 31 stops. . At this time, the opening degree of the radiator port 221 remains 100%. That is, at this time, only the radiator port 221 has an opening degree of 100% (fully open: the predetermined opening degree).
　本実施形態では、上述のように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ８で前記所定開度（１００％）になった後、Ｐｒ１０、Ｐｒ１２でデバイスポート２２３およびヒータポート２２２が閉じ、Ｐｒ１３でラジエータポート２２１のみ開度が前記所定開度（１００％）になるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, as the valve body 31 is rotationally driven to one side in the rotational direction, the ECU 8 is configured such that all the opening degrees of the radiator port 221, the heater port 222, and the device port 223 are Pr8. After reaching the degree (100%), the device port 223 and the heater port 222 are closed by Pr10 and Pr12, and the opening of only the radiator port 221 is set to the predetermined opening (100%) at Pr13 and the valve body 70 31 can be controlled.
　また、本実施形態では、上述のように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ８で前記所定開度（１００％）になった後、ヒータポート２２２およびデバイスポート２２３がデバイスポート２２３、ヒータポート２２２の順（Ｐｒ１０、Ｐｒ１２）で閉じるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, the ECU 8 is configured such that the opening degree of the radiator port 221, the heater port 222, and the device port 223 is Pr8 as the valve body 31 is rotationally driven to one side in the rotational direction. After reaching the predetermined opening (100%), the drive unit 70 and the valve body 31 can be controlled so that the heater port 222 and the device port 223 are closed in the order of the device port 223 and the heater port 222 (Pr10, Pr12).
　　（第２３実施形態）
　第２３実施形態によるバルブ装置について図１２３に基づき説明する。第２３実施形態は、弁体３１の構成、駆動部７０および弁体３１の制御の仕方等が第１５実施形態と異なる。 (23rd Embodiment)
A valve device according to a twenty-third embodiment will be described with reference to FIG. The twenty-third embodiment is different from the fifteenth embodiment in the configuration of the valve body 31, the manner of controlling the drive unit 70 and the valve body 31, and the like.
　本実施形態では、弁体３１の周方向における弁体開口部４１０、４２０、４３０の形成位置および大きさが第１５実施形態と異なる。 In this embodiment, the formation positions and sizes of the valve body openings 410, 420, and 430 in the circumferential direction of the valve body 31 are different from those in the fifteenth embodiment.
＜１２－４＞
　図１２３に示すように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度が前記所定開度になった後、ヒータポート２２２およびデバイスポート２２３が同時に閉じるよう駆動部７０および弁体３１を制御可能である。 <12-4>
As shown in FIG. 123, as the valve body 31 is rotationally driven to one side in the rotational direction, the ECU 8 is configured so that all the opening degrees of the radiator port 221, the heater port 222, and the device port 223 become the predetermined opening degree. The drive unit 70 and the valve body 31 can be controlled so that the heater port 222 and the device port 223 are simultaneously closed.
　そのため、エンジン２の高負荷時、ヒータ６、デバイス７からの熱交換を即座に遮断し、エンジン２の冷却速度および冷却効率を高めることができる。 Therefore, when the engine 2 is under a high load, the heat exchange from the heater 6 and the device 7 can be immediately interrupted, and the cooling rate and cooling efficiency of the engine 2 can be increased.
　次に、本実施形態のバルブ装置１０における冷却水のフローダイアグラムについて、図１２３に基づき詳細に説明する。 Next, a flow diagram of the cooling water in the valve device 10 of the present embodiment will be described in detail based on FIG.
　図１２３に示すように、弁体３１の回転位置が基準位置である０のとき（図１２３における回転位置Ｐｒ０のとき）、すなわち、第１規制凸部３３２または第２規制凸部３４２の一方が規制部６３１に当接し弁体３１の回転が規制されているとき、ラジエータポート２２１、ヒータポート２２２、デバイスポート２２３の開度は、いずれも、０％（全閉）である。以下、Ｐｒ０～１１と記載した場合、図１２３における回転位置Ｐｒ０～１１を意味する。 As shown in FIG. 123, when the rotational position of the valve body 31 is 0, which is the reference position (when the rotational position Pr0 in FIG. 123), that is, one of the first restriction convex part 332 or the second restriction convex part 342 is When the rotation of the valve body 31 is restricted by contacting the restricting portion 631, the opening degrees of the radiator port 221, the heater port 222, and the device port 223 are all 0% (fully closed). Hereinafter, when described as Pr0 to 11, it means the rotational positions Pr0 to Pr11 in FIG.
　弁体３１の回転に伴うラジエータポート２２１、ヒータポート２２２、デバイスポート２２３の開度の変化の仕方は、弁体３１の回転位置がＰｒ０～８までは、第１５実施形態と同様のため、説明を省略する。 The way of changing the opening degree of the radiator port 221, the heater port 222, and the device port 223 according to the rotation of the valve body 31 is the same as that of the fifteenth embodiment when the rotational position of the valve body 31 is Pr0 to Pr8. Is omitted.
　弁体３１がＰｒ８から回転方向の一方側にさらに回転駆動すると、Ｐｒ９とＰｒ１０との間で、ヒータポート２２２の開度およびデバイスポート２２３の開度が１００％から所定の割合で減少する。これにより、ヒータ６側およびデバイス７側に流れる冷却水の量がヒータポート２２２の開度およびデバイスポート２２３の開度に応じて減少する。ヒータポート２２２の開度およびデバイスポート２２３の開度は、Ｐｒ１０で０％（全閉）になる。これにより、ヒータポート２２２およびデバイスポート２２３が閉じ、ヒータ６側およびデバイス７側への冷却水の流れが遮断される。 When the valve element 31 is further rotated from Pr8 to one side in the rotation direction, the opening degree of the heater port 222 and the opening degree of the device port 223 are decreased from 100% at a predetermined rate between Pr9 and Pr10. Thereby, the amount of cooling water flowing to the heater 6 side and the device 7 side decreases according to the opening degree of the heater port 222 and the opening degree of the device port 223. The opening degree of the heater port 222 and the opening degree of the device port 223 become 0% (fully closed) at Pr10. Thereby, the heater port 222 and the device port 223 are closed, and the flow of the cooling water to the heater 6 side and the device 7 side is blocked.
　ここで、弁体３１の単位回転角度当りのＰｒ９とＰｒ１０との間におけるヒータポート２２２の開度の減少割合は、Ｐｒ９とＰｒ１０との間におけるデバイスポート２２３の開度の減少割合と同じである。 Here, the decreasing rate of the opening degree of the heater port 222 between Pr9 and Pr10 per unit rotation angle of the valve body 31 is the same as the decreasing rate of the opening degree of the device port 223 between Pr9 and Pr10. .
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ１１で、第１規制凸部３３２または第２規制凸部３４２の他方が規制部６３１に当接し、弁体３１の回転駆動が停止する。このとき、ラジエータポート２２１の開度は、１００％のままである。すなわち、このとき、ラジエータポート２２１のみ開度が１００％（全開：前記所定開度）になっている。 When the valve body 31 is further rotationally driven to one side in the rotational direction, at Pr11, the other of the first restriction convex part 332 or the second restriction convex part 342 contacts the restriction part 631, and the rotational drive of the valve body 31 is stopped. . At this time, the opening degree of the radiator port 221 remains 100%. That is, at this time, only the radiator port 221 has an opening degree of 100% (fully open: the predetermined opening degree).
　本実施形態では、上述のように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ８で前記所定開度（１００％）になった後、Ｐｒ１０でヒータポート２２２およびデバイスポート２２３が閉じ、Ｐｒ１１でラジエータポート２２１のみ開度が前記所定開度（１００％）になるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, as the valve body 31 is rotationally driven to one side in the rotational direction, the ECU 8 is configured such that all the opening degrees of the radiator port 221, the heater port 222, and the device port 223 are Pr8. After that, the heater port 222 and the device port 223 are closed with Pr10, and the drive unit 70 and the valve body 31 are set so that the opening degree of only the radiator port 221 becomes the predetermined opening degree (100%) with Pr11. It can be controlled.
　また、本実施形態では、上述のように、ＥＣＵ８は、弁体３１が回転方向の一方側に回転駆動するに従い、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ８で前記所定開度（１００％）になった後、ヒータポート２２２およびデバイスポート２２３が同時（Ｐｒ１０）に閉じるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, the ECU 8 is configured such that the opening degree of the radiator port 221, the heater port 222, and the device port 223 is Pr8 as the valve body 31 is rotationally driven to one side in the rotational direction. After reaching the predetermined opening (100%), the drive unit 70 and the valve body 31 can be controlled so that the heater port 222 and the device port 223 are simultaneously closed (Pr10).

The valve body 31 is rotationally driven, for example, in summer when the environmental temperature is higher than a predetermined temperature, the valve body 31 is rotationally driven in a cooling priority mode in which the valve body 31 is rotated on the other side with respect to the reference position in the rotational direction. . In other embodiments, the ECU 8 may be configured according to the operating state of the air conditioner as a vehicle state, such as rotating the valve body 31 in a normal mode when the air conditioner is off, and in a cooling priority mode when the air conditioner is on. The normal mode and the cooling priority mode may be switched. Further, the ECU 8 may switch between the normal mode and the cooling priority mode according to both the vehicle environment and the vehicle state. Furthermore, the ECU 8 determines that “the vehicle environment such as the outside air temperature, the temperature inside the vehicle interior, or the temperature difference between the outside air temperature and the vehicle interior temperature” and / or “the load state of the engine 2, the vehicle speed, or the acceleration of the vehicle 1. The normal mode and the cooling priority mode may be switched according to the vehicle state other than the air conditioner operating state such as the state.
　ＥＣＵ８は、通常モードの弁体３１の特定の回転位置において、ラジエータポート２２１のみ開度が０より大きい所定開度になるよう駆動部７０および弁体３１を制御可能である。 The ECU 8 can control the drive unit 70 and the valve body 31 so that only the radiator port 221 has a predetermined opening larger than 0 at a specific rotational position of the valve body 31 in the normal mode.
　そのため、通常モードにおいても、エンジン２の冷却効率を高めることが可能な程度の開度に前記所定開度を設定し、ラジエータポート２２１のみ開度が前記所定開度になるよう駆動部７０および弁体３１を制御することで、エンジン２の高負荷時の冷却効率の最大化を図ることができる。 Therefore, even in the normal mode, the predetermined opening is set to such an extent that the cooling efficiency of the engine 2 can be increased, and only the radiator port 221 has the predetermined opening so that the opening becomes the predetermined opening. By controlling the body 31, the cooling efficiency at the time of high load of the engine 2 can be maximized.

　次に、本実施形態のバルブ装置１０における冷却水のフローダイアグラムについて、図１２４、１２５に基づき詳細に説明する。 Next, a flow diagram of cooling water in the valve device 10 of the present embodiment will be described in detail based on FIGS.
　図１２４、１２５に示すように、弁体３１の回転位置が基準位置である０（度）のとき（図１２５における回転位置Ｐｒ０のとき）、ラジエータポート２２１、ヒータポート２２２、デバイスポート２２３の開度は、いずれも、０％（全閉）である。以下、Ｐｒ－５～１０と記載した場合、図１２５における回転位置Ｐｒ－５～１０を意味する。 As shown in FIGS. 124 and 125, when the rotational position of the valve body 31 is 0 (degrees), which is the reference position (at the rotational position Pr0 in FIG. 125), the radiator port 221, the heater port 222, and the device port 223 are opened. In all cases, the degree is 0% (fully closed). Hereinafter, Pr-5 to 10 means the rotational positions Pr-5 to 10 in FIG.
　上述のように、ＥＣＵ８は、車両環境および／または車両状態に応じて、弁体３１を回転方向の基準位置である０（度）に対し一方側（Ｐｒ０～１０）において回転させる通常モード、あるいは回転方向の基準位置に対し他方側（Ｐｒ０～－５）において回転させる冷却優先モードで弁体３１を回転駆動する。 As described above, the ECU 8 performs the normal mode in which the valve body 31 is rotated on one side (Pr0 to 10) with respect to 0 (degrees) that is the reference position in the rotation direction, depending on the vehicle environment and / or the vehicle state, or The valve element 31 is rotationally driven in a cooling priority mode in which the rotation is performed on the other side (Pr0 to −5) with respect to the reference position in the rotation direction.
　ＥＣＵ８の通常モードによる弁体３１の制御によって、弁体３１が回転方向の一方側に回転駆動し、弁体３１の回転位置が０から大きくなると、Ｐｒ１とＰｒ２との間で、ヒータポート２２２の開度が０（％）から所定の割合で増大する。これにより、ヒータポート２２２の開度に応じた量の冷却水がヒータ６側に流れる。ヒータポート２２２の開度は、Ｐｒ２で１００％（全開：前記所定開度）に達する。 When the valve body 31 is rotationally driven to one side in the rotational direction by the control of the valve body 31 in the normal mode of the ECU 8, and the rotational position of the valve body 31 increases from 0, the heater port 222 is connected between Pr1 and Pr2. The opening degree increases from 0 (%) at a predetermined rate. Thereby, an amount of cooling water corresponding to the opening degree of the heater port 222 flows to the heater 6 side. The opening degree of the heater port 222 reaches 100% (full open: the predetermined opening degree) at Pr2.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ３とＰｒ４との間で、デバイスポート２２３の開度が０（％）から所定の割合で増大する。これにより、デバイスポート２２３の開度に応じた量の冷却水がデバイス７側に流れる。デバイスポート２２３の開度は、Ｐｒ４で１００％（全開：前記所定開度）に達する。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the device port 223 increases from 0 (%) to a predetermined ratio between Pr3 and Pr4. Thereby, an amount of cooling water corresponding to the opening degree of the device port 223 flows to the device 7 side. The opening degree of the device port 223 reaches 100% at Pr4 (fully open: the predetermined opening degree).
　ここで、弁体３１の単位回転角度当りのＰｒ１とＰｒ２との間におけるヒータポート２２２の開度の増大割合は、Ｐｒ３とＰｒ４との間におけるデバイスポート２２３の開度の増大割合と同じである（図１２４、１２５参照）。 Here, the increasing rate of the opening degree of the heater port 222 between Pr1 and Pr2 per unit rotation angle of the valve body 31 is the same as the increasing rate of the opening degree of the device port 223 between Pr3 and Pr4. (See FIGS. 124 and 125).
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ５とＰｒ６との間で、ラジエータポート２２１の開度が０（％）から所定の割合で増大する。これにより、ラジエータポート２２１の開度に応じた量の冷却水がラジエータ５側に流れる。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the radiator port 221 increases from 0 (%) at a predetermined rate between Pr5 and Pr6. Thereby, an amount of cooling water corresponding to the opening degree of the radiator port 221 flows to the radiator 5 side.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ６とＰｒ７との間で、ラジエータポート２２１の開度が所定の割合でさらに増大する。ラジエータポート２２１の開度は、Ｐｒ７で１００％（全開：前記所定開度）に達する。そのため、Ｐｒ７において、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度が前記所定開度すなわち１００％になる。 When the valve body 31 is further rotationally driven to one side in the rotational direction, the opening degree of the radiator port 221 further increases at a predetermined rate between Pr6 and Pr7. The opening degree of the radiator port 221 reaches 100% (full opening: the predetermined opening degree) at Pr7. Therefore, in Pr7, all the openings of the radiator port 221, the heater port 222, and the device port 223 become the predetermined opening, that is, 100%.
　ここで、弁体３１の単位回転角度当りのＰｒ５とＰｒ６との間におけるラジエータポート２２１の開度の増大割合は、Ｐｒ６とＰｒ７との間におけるラジエータポート２２１の開度の増大割合より小さい（図１２４、１２５参照）。これは、ラジエータ用開口部４１０が延伸開口部４１３と大開口部４１２とから形成されていることによる（図９３、９４等参照）。 Here, the increasing rate of the opening of the radiator port 221 between Pr5 and Pr6 per unit rotation angle of the valve body 31 is smaller than the increasing rate of the opening of the radiator port 221 between Pr6 and Pr7 (FIG. 124, 125). This is because the radiator opening 410 is formed of the extended opening 413 and the large opening 412 (see FIGS. 93 and 94).
　そのため、ラジエータポート２２１の開弁初期において、ラジエータ５への冷却水の流量を徐々に大きくすることができる。これにより、通常モードにおいて、ラジエータ５の熱交換による冷却水の急激な温度変化を抑制することができる。 Therefore, at the initial opening of the radiator port 221, the flow rate of the cooling water to the radiator 5 can be gradually increased. Thereby, the rapid temperature change of the cooling water by heat exchange of the radiator 5 can be suppressed in the normal mode.
　また、弁体３１の単位回転角度当りのＰｒ５とＰｒ６との間におけるラジエータポート２２１の開度の増大割合、および、Ｐｒ６とＰｒ７との間におけるラジエータポート２２１の開度の増大割合は、Ｐｒ１とＰｒ２との間におけるヒータポート２２２の開度の増大割合、Ｐｒ３とＰｒ４との間におけるデバイスポート２２３の開度の増大割合より小さい（図１２４、１２５参照）。 Further, the rate of increase of the opening of the radiator port 221 between Pr5 and Pr6 per unit rotation angle of the valve body 31, and the rate of increase of the opening of the radiator port 221 between Pr6 and Pr7 are Pr1 and Pr6. The rate of increase in the opening degree of the heater port 222 with respect to Pr2 is smaller than the rate of increase in the opening degree of the device port 223 between Pr3 and Pr4 (see FIGS. 124 and 125).
　そのため、開弁初期におけるラジエータ５への冷却水の流量変化を、ヒータ６、デバイス７への冷却水の流量変化と比べ、緩やかにすることができる。これにより、通常モードにおいて、ラジエータ５の熱交換による冷却水の急激な温度変化を抑制することができる。 Therefore, the change in the flow rate of the cooling water to the radiator 5 at the initial stage of the valve opening can be made slower than the change in the flow rate of the cooling water to the heater 6 and the device 7. Thereby, the rapid temperature change of the cooling water by heat exchange of the radiator 5 can be suppressed in the normal mode.
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ８とＰｒ９との間で、ヒータポート２２２の開度およびデバイスポート２２３の開度が１００％から所定の割合で減少する。これにより、ヒータ６側およびデバイス７側に流れる冷却水の量がヒータポート２２２の開度およびデバイスポート２２３の開度に応じて減少する。ヒータポート２２２の開度およびデバイスポート２２３の開度は、Ｐｒ９で０％（全閉）になる。これにより、ヒータポート２２２およびデバイスポート２２３が閉じ、ヒータ６側およびデバイス７側への冷却水の流れが遮断される。 When the valve body 31 is further rotated to one side in the rotation direction, the opening degree of the heater port 222 and the opening degree of the device port 223 are decreased from 100% at a predetermined rate between Pr8 and Pr9. Thereby, the amount of cooling water flowing to the heater 6 side and the device 7 side decreases according to the opening degree of the heater port 222 and the opening degree of the device port 223. The opening degree of the heater port 222 and the opening degree of the device port 223 become 0% (fully closed) at Pr9. Thereby, the heater port 222 and the device port 223 are closed, and the flow of the cooling water to the heater 6 side and the device 7 side is blocked.
　ここで、弁体３１の単位回転角度当りのＰｒ８とＰｒ９との間におけるヒータポート２２２の開度の減少割合は、Ｐｒ８とＰｒ９との間におけるデバイスポート２２３の開度の減少割合と同じである（図１２４、１２５参照）。 Here, the decreasing rate of the opening degree of the heater port 222 between Pr8 and Pr9 per unit rotation angle of the valve body 31 is the same as the decreasing rate of the opening degree of the device port 223 between Pr8 and Pr9. (See FIGS. 124 and 125).
　弁体３１が回転方向の一方側にさらに回転駆動すると、Ｐｒ１０で、第１規制凸部３３２または第２規制凸部３４２の一方が規制部６３１に当接し、弁体３１の回転駆動が停止する。このとき、ラジエータポート２２１の開度は、１００％のままである。すなわち、このとき、ラジエータポート２２１のみ開度が１００％（全開：前記所定開度）になっている。 When the valve body 31 is further rotationally driven to one side in the rotational direction, at Pr10, one of the first restriction convex part 332 or the second restriction convex part 342 contacts the restriction part 631, and the rotational drive of the valve body 31 stops. . At this time, the opening degree of the radiator port 221 remains 100%. That is, at this time, only the radiator port 221 has an opening degree of 100% (fully open: the predetermined opening degree).
　ＥＣＵ８の冷却優先モードによる弁体３１の制御によって、弁体３１が回転方向の他方側に回転駆動し、弁体３１の回転位置が０から小さくなると、Ｐｒ－１とＰｒ－２との間で、デバイスポート２２３の開度が０（％）から所定の割合で増大する。これにより、デバイスポート２２３の開度に応じた量の冷却水がデバイス７側に流れる。デバイスポート２２３の開度は、Ｐｒ－２で１００％（全開：前記所定開度）に達する。 When the valve body 31 is driven to rotate to the other side in the rotational direction by the control of the valve body 31 in the cooling priority mode of the ECU 8, and the rotational position of the valve body 31 is reduced from 0, it is between Pr-1 and Pr-2. The opening degree of the device port 223 increases from 0 (%) at a predetermined rate. Thereby, an amount of cooling water corresponding to the opening degree of the device port 223 flows to the device 7 side. The opening degree of the device port 223 reaches 100% (full opening: the predetermined opening degree) at Pr-2.
　ここで、弁体３１の単位回転角度当りのＰｒ－１とＰｒ－２との間におけるデバイスポート２２３の開度の増大割合は、Ｐｒ３とＰｒ４との間におけるデバイスポート２２３の開度の増大割合と同じである（図１２４、１２５参照）。 Here, the increasing rate of the opening degree of the device port 223 between Pr-1 and Pr-2 per unit rotation angle of the valve body 31 is the increasing rate of the opening degree of the device port 223 between Pr3 and Pr4. (See FIGS. 124 and 125).
　弁体３１が回転方向の他方側にさらに回転駆動すると、Ｐｒ－３とＰｒ－４との間で、ラジエータポート２２１の開度が０（％）から所定の割合で増大する。これにより、ラジエータポート２２１の開度に応じた量の冷却水がラジエータ５側に流れる。ラジエータポート２２１の開度は、Ｐｒ－４で１００％（全開：前記所定開度）に達する。そのため、Ｐｒ－４において、ラジエータポート２２１およびデバイスポート２２３の開度が前記所定開度すなわち１００％になる。 When the valve body 31 is further rotated to the other side in the rotation direction, the opening degree of the radiator port 221 increases from 0 (%) at a predetermined rate between Pr-3 and Pr-4. Thereby, an amount of cooling water corresponding to the opening degree of the radiator port 221 flows to the radiator 5 side. The opening degree of the radiator port 221 reaches 100% at Pr-4 (fully open: the predetermined opening degree). Therefore, at Pr-4, the opening degree of the radiator port 221 and the device port 223 becomes the predetermined opening degree, that is, 100%.
　ここで、弁体３１の単位回転角度当りのＰｒ－３とＰｒ－４との間におけるラジエータポート２２１の開度の増大割合は、Ｐｒ６とＰｒ７との間におけるラジエータポート２２１の開度の増大割合と同じである（図１２４、１２５参照）。 Here, the increase rate of the opening of the radiator port 221 between Pr-3 and Pr-4 per unit rotation angle of the valve body 31 is the increase rate of the opening of the radiator port 221 between Pr6 and Pr7. (See FIGS. 124 and 125).
　弁体３１が回転方向の他方側にさらに回転駆動すると、Ｐｒ－５で、第１規制凸部３３２または第２規制凸部３４２の他方が規制部６３１に当接し、弁体３１の回転駆動が停止する。このとき、ラジエータポート２２１の開度およびデバイスポート２２３の開度は、１００％のままである。すなわち、このとき、ラジエータポート２２１の開度およびデバイスポート２２３の開度は１００％（全開：前記所定開度）になっている。 When the valve body 31 is further rotationally driven to the other side in the rotational direction, at Pr-5, the other of the first restriction convex part 332 or the second restriction convex part 342 comes into contact with the restriction part 631, and the valve body 31 is rotationally driven. Stop. At this time, the opening degree of the radiator port 221 and the opening degree of the device port 223 remain 100%. That is, at this time, the opening degree of the radiator port 221 and the opening degree of the device port 223 are 100% (fully open: the predetermined opening degree).
　本実施形態では、上述のように、ＥＣＵ８は、通常モードの弁体３１の特定の回転位置であるＰｒ９～１０において、ラジエータポート２２１のみ開度が０より大きい所定開度になるよう駆動部７０および弁体３１を制御可能である。 In the present embodiment, as described above, the ECU 8 controls the drive unit 70 so that only the radiator port 221 has a predetermined opening larger than 0 at Pr9 to 10 which are specific rotational positions of the valve body 31 in the normal mode. And the valve body 31 can be controlled.
　また、ＥＣＵ８は、通常モードのＰｒ７～１０、および、冷却優先モードのＰｒ－４～－５において、ラジエータポート２２１が前記所定開度になるよう駆動部７０および弁体３１を制御可能である。 Further, the ECU 8 can control the drive unit 70 and the valve body 31 so that the radiator port 221 is at the predetermined opening degree in the normal mode Pr7 to 10 and the cooling priority mode Pr-4 to -5.
　また、ＥＣＵ８は、ラジエータポート２２１、ヒータポート２２２またはデバイスポート２２３の開度がそれぞれ、Ｐｒ９～１０、Ｐｒ２～３、Ｐｒ－２～－３において、単独で前記所定開度になるよう駆動部７０および弁体３１を制御可能である。 Further, the ECU 8 drives the driving unit 70 so that the opening degree of the radiator port 221, the heater port 222 or the device port 223 becomes the predetermined opening degree independently at Pr9 to 10, Pr2 to 3, and Pr-2 to -3, respectively. And the valve body 31 can be controlled.
　また、ＥＣＵ８は、通常モードにおいて、ラジエータポート２２１、ヒータポート２２２およびデバイスポート２２３の全ての開度がＰｒ７～８において前記所定開度になるよう駆動部７０および弁体３１を制御可能である。 In the normal mode, the ECU 8 can control the drive unit 70 and the valve body 31 so that all the opening degrees of the radiator port 221, the heater port 222, and the device port 223 become the predetermined opening degree in Pr7-8.
　　（第２５実施形態）
　第２５実施形態によるバルブ装置の一部を図１２６に示す。第２５実施形態は、軸受部６０２近傍の構成が第１実施形態と異なる。 (25th Embodiment)
A part of the valve device according to the twenty-fifth embodiment is shown in FIG. The twenty-fifth embodiment differs from the first embodiment in the configuration near the bearing portion 602.
＜６－２３＞
　図１２６に示すように、本実施形態は、軸シール部材６０３に代えて、シャフトシール部９６を備えている。 <6-23>
As shown in FIG. 126, this embodiment includes a shaft seal portion 96 instead of the shaft seal member 603.
　シャフトシール部９６は、シャフト挿通穴６２に設けられ、内縁部がシャフト３２の外周壁に当接可能な環状のシール部環状部材９７、および、シール部環状部材９７より柔らかく内縁部がシャフト３２の外周壁に当接しシャフト３２との間を液密に保持可能な環状のシャフトシール部材９８を有する。 The shaft seal portion 96 is provided in the shaft insertion hole 62, and an annular seal portion annular member 97 whose inner edge portion can abut against the outer peripheral wall of the shaft 32, and the inner edge portion of the shaft 32 is softer than the seal portion annular member 97. An annular shaft seal member 98 that abuts on the outer peripheral wall and can hold fluid tightly between the shaft 32 is provided.
　本実施形態では、シャフト３２の径方向外側に入口ポート２２０が形成されている。そのため、入口ポート２２０から内部空間２００に流入した冷却水がシャフト３２の外周壁にぶつかり、シャフト３２の軸ブレが生じやすい。シャフト３２に軸ブレが生じると、シャフトシール部材９８への負荷が増大するおそれがある。 In this embodiment, the inlet port 220 is formed on the radially outer side of the shaft 32. Therefore, the cooling water flowing into the internal space 200 from the inlet port 220 collides with the outer peripheral wall of the shaft 32, and the shaft 32 is likely to be shaken. When shaft blurring occurs in the shaft 32, the load on the shaft seal member 98 may increase.
　そこで、本実施形態では、上記構成のシャフトシール部９６を設け、シール部環状部材９７によりシャフト３２の軸ブレを抑制し、軸ブレによるシャフトシール部材９８への負荷の低減を図っている。これにより、シャフトシール部材９８の劣化、摩耗、変形等によるシール性の低下を抑制できる。 Therefore, in this embodiment, the shaft seal portion 96 having the above-described configuration is provided, and the shaft portion of the shaft 32 is suppressed by the seal portion annular member 97 to reduce the load on the shaft seal member 98 due to the shaft shake. Thereby, the deterioration of the sealing performance due to deterioration, wear, deformation or the like of the shaft seal member 98 can be suppressed.
＜６－２４＞
　シャフトシール部９６は、シール部環状部材９７より硬くシャフト挿通穴６２においてシール部環状部材９７およびシャフトシール部材９８を保持可能なシール部保持部材９９をさらに有している。 <6-24>
The shaft seal portion 96 further includes a seal portion holding member 99 that is harder than the seal portion annular member 97 and can hold the seal portion annular member 97 and the shaft seal member 98 in the shaft insertion hole 62.
　そのため、シャフト挿通穴６２におけるシール部環状部材９７およびシャフトシール部材９８の位置を安定させることができる。したがって、シール部環状部材９７によりシャフト３２の軸ブレを効果的に抑制するとともに、軸ブレによるシャフトシール部材９８への負荷を効果的に低減できる。 Therefore, the positions of the seal portion annular member 97 and the shaft seal member 98 in the shaft insertion hole 62 can be stabilized. Therefore, the shaft portion of the shaft 32 is effectively suppressed by the seal portion annular member 97, and the load on the shaft seal member 98 due to the shaft shake can be effectively reduced.
＜６－２５＞
　シール部環状部材９７は、樹脂により形成されている。シャフトシール部材９８は、ゴムにより形成されている。シール部保持部材９９は、金属により形成されている。 <6-25>
The seal portion annular member 97 is made of resin. The shaft seal member 98 is made of rubber. The seal portion holding member 99 is made of metal.
　そのため、シール部環状部材９７によりシャフト３２の軸ブレを効果的に抑制し、シャフトシール部材９８のシール性を確保し、シール部保持部材９９によりシール部環状部材９７およびシャフトシール部材９８を安定して保持することができる。 Therefore, the shaft portion of the shaft 32 is effectively suppressed by the seal portion annular member 97, the sealing performance of the shaft seal member 98 is secured, and the seal portion annular member 97 and the shaft seal member 98 are stabilized by the seal portion holding member 99. Can be held.
＜６－２６＞
　シャフトシール部材９８は、シール部環状部材９７とシャフト３２の外周壁との当接箇所に対し弁体３１側においてシャフト３２の外周壁に当接する第１シャフトシール部材９８１、および、シール部環状部材９７とシャフト３２の外周壁との当接箇所に対し駆動部７０側においてシャフト３２の外周壁に当接する第２シャフトシール部材９８２を有する。 <6-26>
The shaft seal member 98 includes a first shaft seal member 981 that abuts the outer peripheral wall of the shaft 32 on the valve body 31 side with respect to a contact portion between the seal portion annular member 97 and the outer peripheral wall of the shaft 32, and the seal portion annular member The second shaft seal member 982 is in contact with the outer peripheral wall of the shaft 32 on the drive unit 70 side with respect to the contact portion between 97 and the outer peripheral wall of the shaft 32.
　そのため、１つのシール部環状部材９７により、シャフト３２の軸ブレを抑制し、軸ブレによる第１シャフトシール部材９８１および第２シャフトシール部材９８２への負荷を低減できる。また、シール部環状部材９７の弁体３１側および駆動部７０側においてシャフト３２の外周壁に当接する第１シャフトシール部材９８１および第２シャフトシール部材９８２により、シャフト３２の外周のシール性をより高めることができる。 Therefore, the shaft seal of the shaft 32 can be suppressed by the single seal portion annular member 97, and the load on the first shaft seal member 981 and the second shaft seal member 982 due to the shaft shake can be reduced. Further, the first shaft seal member 981 and the second shaft seal member 982 that contact the outer peripheral wall of the shaft 32 on the valve body 31 side and the drive unit 70 side of the seal portion annular member 97 further improve the sealing performance of the outer periphery of the shaft 32. Can be increased.
　以下、シャフトシール部９６の構成について、より詳細に説明する。 Hereinafter, the configuration of the shaft seal portion 96 will be described in more detail.
　シール部環状部材９７は、例えばＰＴＦＥ（ポリテトラフルオロエチレン）等の樹脂により環状に形成されている。シール部環状部材９７は、内縁部がシャフト３２の外周壁に当接および摺動可能に設けられている。シール部環状部材９７を摩擦係数の小さいＰＴＦＥで形成することにより、シャフト３２は、シール部環状部材９７の内側で円滑に回転可能である。なお、シール部環状部材９７は、隔壁貫通穴６５に対し弁体３１側に設けられている（図１２６参照）。 The seal portion annular member 97 is formed in an annular shape from a resin such as PTFE (polytetrafluoroethylene).

　シール部保持部材９９は、外側シール部保持部材９９０、内側シール部保持部材９９１、９９２、９９３を有している。外側シール部保持部材９９０、内側シール部保持部材９９１、９９２、９９３は、例えば金属により形成されている。 The seal part holding member 99 has an outer seal part holding member 990 and inner seal part holding members 991, 992, and 993. The outer seal portion holding member 990 and the inner seal portion holding members 991, 992, and 993 are made of, for example, metal.
　外側シール部保持部材９９０は、筒状に形成され、外周壁がシャフト挿通穴６２に嵌合するよう設けられている。外側シール部保持部材９９０は、内周壁が第１シャフトシール部材９８１の外周壁に当接するようにして第１シャフトシール部材９８１を保持している。 The outer seal portion holding member 990 is formed in a cylindrical shape, and is provided so that the outer peripheral wall is fitted in the shaft insertion hole 62.

The inner seal portion holding member 991 holds the end portion of the first shaft seal member 981 on the valve body 31 side.
　内側シール部保持部材９９２は、筒状に形成され、外周壁が第１シャフトシール部材９８１の駆動部７０側の端部の内周壁に当接するよう、外側シール部保持部材９９０および第１シャフトシール部材９８１の駆動部７０側の端部の内側に設けられている。内側シール部保持部材９９２は、内周壁がシール部環状部材９７の外縁部に当接するようにしてシール部環状部材９７を保持している。 The inner seal portion holding member 992 is formed in a cylindrical shape, and the outer seal portion holding member 990 and the first shaft seal are arranged such that the outer peripheral wall comes into contact with the inner peripheral wall of the end portion of the first shaft seal member 981 on the drive portion 70 side.

The inner seal portion holding member 993 holds the seal portion annular member 97 such that the end portion on the valve body 31 side comes into contact with the surface on the drive portion 70 side of the seal portion annular member 97.
