自動車のエンジン冷却系では、機械式または電動のウォータポンプとサーモスタットやバルブを用いたシステムがある。そして近年のハイブリッド車や、アイドリングストップ車の普及とあいまって、電動式ウォータポンプの需要が増えている。これは、これらの車はエンジンが止まっていてもエンジンや室内を適切な温度に保つ必要があるからである。   In an automobile engine cooling system, there is a system using a mechanical or electric water pump and a thermostat or a valve. Along with the recent spread of hybrid vehicles and idling stop vehicles, the demand for electric water pumps is increasing. This is because these vehicles need to keep the engine and the room at an appropriate temperature even when the engine is stopped.

特開２０１２−１６７５７３号公報JP 2012-167573 A

自動車のエンジンルーム内に冷却系を配置するには、前記ポンプ等の機器を備え付ける土台や、組み付け部品や水路ホースが必要となる。これらの部品や水路ホースは、組み付けスペースのコンパクト化を困難とし、重量の増加や組み付け工数の増大化という課題を有している。   In order to arrange a cooling system in the engine room of an automobile, a base on which equipment such as the pump is provided, an assembly part, and a waterway hose are required. These parts and the waterway hose make it difficult to make the assembly space compact, and have the problems of increasing the weight and increasing the number of assembly steps.

特許文献１には、電磁石と圧縮ばねで、鉄等の磁性体でできた弁体を開閉制御する電磁弁が示されている。これは、エンジン、ラジエータ、ヒータコア等の機器を冷却液の循環路で接続して、車両用の冷却装置を構成したものである。そして、電動ウォータポンプで送り出された前記冷却液が、前記電磁弁で制御されている。ここでも、まとめられる機器はなるべく一体化して、更なる、前記循環路の効率化と、冷却装置全体の省スペース化をすることが課題となっている。   Patent Document 1 discloses an electromagnetic valve that controls opening and closing of a valve body made of a magnetic material such as iron using an electromagnet and a compression spring. In this device, a cooling device for a vehicle is configured by connecting devices such as an engine, a radiator, and a heater core through a coolant circulation path. And the said cooling liquid sent out with the electric water pump is controlled by the said solenoid valve. Also here, the devices to be combined are integrated as much as possible to further improve the efficiency of the circulation path and to save the space of the entire cooling device.

そこで本発明は、冷却系を構成する機器の一体化により、循環路の効率化と、冷却装置全体の省スペース化及び、組み付け工数の省力化を可能とする電磁弁を提供することを目的とする。   Accordingly, an object of the present invention is to provide an electromagnetic valve that can improve efficiency of a circulation path, save space in the entire cooling device, and save labor in assembling man-hours by integrating devices constituting a cooling system. To do.

本発明の目的は、電動機に隣接した電磁弁であって、磁性を帯びた弁体と、該弁体の付勢手段と、電磁コイルと、流入路と、流出路を有し、前記電磁コイルは、前記電動機のステータコアのティース部を該電動機ロータの回転軸方向に延長して巻き線コアとし、少なくとも、前記付勢手段の付勢力と前記電磁コイルの磁力で前記弁体を移動させることを特徴とする電磁弁によって達成される。   An object of the present invention is an electromagnetic valve adjacent to an electric motor, which has a magnetic valve body, an urging means for the valve body, an electromagnetic coil, an inflow path, and an outflow path, and the electromagnetic coil Extends the tooth portion of the stator core of the motor in the direction of the rotation axis of the motor rotor to form a winding core, and moves the valve body by at least the urging force of the urging means and the magnetic force of the electromagnetic coil. This is achieved by a characteristic solenoid valve.

本発明の電磁弁は、電動機と一体化することで、自動車の冷却系装置の部品点数の削減、組み付け工数の削減の効果がある。また、前記部品点数の削減により、前記冷却系装置の軽量化、信頼性の向上、省スペース化の効果がある。また、省スペース化により、前記冷却系装置の循環路の短縮化が可能となり冷却機能の効率化が図れる効果がある。   By integrating the electromagnetic valve of the present invention with an electric motor, there is an effect of reducing the number of parts of an automobile cooling system and reducing the number of assembly steps. Further, the reduction in the number of parts has the effect of reducing the weight of the cooling system, improving the reliability, and saving the space. In addition, the space saving can shorten the circulation path of the cooling system device, and can effectively improve the cooling function.

また、本発明の電磁弁の電磁コイルの磁場の向きと、前記電磁弁に隣接する電動機の駆動磁場とは、直交しているので、お互いの磁場の干渉を最小化する効果がある。   In addition, since the direction of the magnetic field of the electromagnetic coil of the electromagnetic valve of the present invention and the driving magnetic field of the electric motor adjacent to the electromagnetic valve are orthogonal, there is an effect of minimizing the interference between the magnetic fields.

図１に基づいて、本発明の電磁弁の実施の一例を説明する。図１（Ａ）は流路遮断時の、本発明の電磁弁及びこれに隣接する電動機の断面図である。図１（Ｂ）はＸ1−Ｘ1矢視による断面図で、同図（Ｃ）はＸ2−Ｘ2矢視による断面図である。   Based on FIG. 1, an example of implementation of the solenoid valve of this invention is demonstrated. FIG. 1A is a cross-sectional view of the solenoid valve of the present invention and the electric motor adjacent thereto when the flow path is shut off. FIG. 1B is a cross-sectional view taken along arrow X1-X1, and FIG. 1C is a cross-sectional view taken along arrow X2-X2.

図１（Ａ）に示すように本発明の電磁弁は電磁弁ハウジング１と電磁コイル４から成る。そして、電磁弁ハウジング１の内部には、流路１１と、流路１２と、電磁弁１３と、弁体軸１３ａと、弁体規制部１３ｂと、付勢ばね１３ｃが構成されている。本発明の電磁弁は、電動機に接近して構成されていて、電磁弁ハウジング１と電動機ハウジング２は接するか、非常に近接して存在してもよいし、一体成形されていてもよい。   As shown in FIG. 1 (A), the electromagnetic valve of the present invention comprises an electromagnetic valve housing 1 and an electromagnetic coil 4. And inside the electromagnetic valve housing 1, the flow path 11, the flow path 12, the electromagnetic valve 13, the valve body axis | shaft 13a, the valve body control part 13b, and the urging | biasing spring 13c are comprised. The electromagnetic valve of the present invention is configured close to the electric motor, and the electromagnetic valve housing 1 and the electric motor housing 2 may be in contact with each other, or may be in close proximity, or may be integrally formed.

前記電動機は電動機ハウジング２と、ロータ２１と、回転軸２２と、ステータコア３を有する。該ステータコア３には、電動機用巻き線３１ａと３１ｂを有する。そして、ステータコア３には、ティース芯部３３とティース部３２が形成されている。電動機用巻き線３１ａと３１ｂは、ティース芯部３３に巻かれている。更に、ティース部３２が回転軸２２の方向に延長されティース延長部３２ａを構成している。ティース延長部３２ａは、電磁コイル４の巻き線コア４１として用いられ、電磁弁用巻き線４２が巻かれている。   The electric motor has an electric motor housing 2, a rotor 21, a rotating shaft 22, and a stator core 3. The stator core 3 has motor windings 31a and 31b. The stator core 3 is formed with a tooth core portion 33 and a tooth portion 32. The motor windings 31 a and 31 b are wound around the tooth core 33. Furthermore, the teeth part 32 is extended in the direction of the rotating shaft 22 to constitute a tooth extension part 32a. The teeth extension part 32a is used as the winding core 41 of the electromagnetic coil 4, and the electromagnetic valve winding 42 is wound thereon.

ティース延長部３２ａは、図１（Ａ）に示す例では、ステータコア３の外周円筒壁よりも回転軸２２方向に飛び出した部分である。該飛び出し部全体を巻き線コア４１として、電磁弁用巻き線４２を巻いてもよいし、前記飛び出し部の一部を巻き線コア４１として、電磁弁用巻き線４２を巻いてもよい。   In the example shown in FIG. 1A, the tooth extension portion 32 a is a portion that protrudes in the direction of the rotation shaft 22 from the outer peripheral cylindrical wall of the stator core 3. The entire protruding portion may be wound as the winding core 41 and the electromagnetic valve winding 42 may be wound, or the portion of the protruding portion may be wound as the winding core 41 and the electromagnetic valve winding 42 may be wound.

弁体１３は例えば永久磁石を含む部材で構成されていて、上下方向に磁場が発生するように、Ｓ極とＮ極に磁化されている。弁体１３は弁体軸１３ａを通じて、弁体規制部１３ｂによって、上下方向のみに動けるように規制されている。弁体１３と弁体規制部１３ｂの間には付勢ばね１３ｃが装着されていて、弁体規制部１３ｂに対して、弁体１３を一方向へ付勢している。   The valve body 13 is made of, for example, a member including a permanent magnet, and is magnetized to the S pole and the N pole so that a magnetic field is generated in the vertical direction. The valve body 13 is regulated to move only in the vertical direction through the valve body shaft 13a by the valve body regulating portion 13b. A biasing spring 13c is mounted between the valve body 13 and the valve body restricting portion 13b, and biases the valve body 13 in one direction with respect to the valve body restricting portion 13b.

次に図２と図３に基づいて、本発明の電磁弁の動作説明をする。図２は、流路１２に対して、矢印方向ａの向きに、冷却液の圧力が掛かっている場合である。図２（Ａ）においては、弁体１３が流路１２を塞いでいるために、流路１２と流路１１は遮断されている。付勢ばね１３ｃに圧縮ばねを用いた場合は、付勢ばね１３ｃの反発力によって、弁体１３が電磁弁ハウジング１底部に押し付けられて、流路１２を塞いでいる。付勢ばね１３ｃの反発力により、矢印方向ａの液圧に抗して弁体１３が電磁弁ハウジング１底部に押し付けられている。   Next, the operation of the solenoid valve of the present invention will be described with reference to FIGS. FIG. 2 shows a case where the coolant pressure is applied to the flow path 12 in the direction of the arrow a. In FIG. 2A, since the valve body 13 blocks the flow path 12, the flow path 12 and the flow path 11 are blocked. When a compression spring is used as the urging spring 13c, the valve body 13 is pressed against the bottom of the electromagnetic valve housing 1 by the repulsive force of the urging spring 13c, thereby closing the flow path 12. The valve element 13 is pressed against the bottom of the electromagnetic valve housing 1 against the hydraulic pressure in the arrow direction a by the repulsive force of the urging spring 13c.

図２（Ｂ）は、電磁コイル４で上下方向に磁場を発生させて、磁力の反発力によって、弁体１３を上方へ移動させている状態である。このとき、流路１２と流路１１は接続して、流路１２は流入路となり、流路１１は矢印方向ｂへ流出する流出路となる。前記磁力による反発力と矢印方向ａの液圧の和が付勢ばね１３ｃの反発力より大きくなれば、弁体１３が上方へ移動する。   FIG. 2B shows a state where a magnetic field is generated in the vertical direction by the electromagnetic coil 4 and the valve element 13 is moved upward by the repulsive force of the magnetic force. At this time, the flow path 12 and the flow path 11 are connected, the flow path 12 becomes an inflow path, and the flow path 11 becomes an outflow path that flows out in the arrow direction b. When the sum of the repulsive force due to the magnetic force and the hydraulic pressure in the arrow direction a is greater than the repulsive force of the biasing spring 13c, the valve body 13 moves upward.

電磁コイル４に流す電流を調整して前記磁力を弱めたり、前記電流を止めて前記磁力を止めたりすることにより、付勢ばね１３ｃの反発力により弁体１３は再び下方へ移動して、流路１２は遮断される。また、矢印方向ａの液圧が強い場合は、付勢ばね１３ｃの反発力を強めるほか、電磁コイル４で弁体１３を引き付ける磁場を発生させて、弁体１３を下方へ移動させるようにしてもよい。   By adjusting the current flowing through the electromagnetic coil 4 to weaken the magnetic force, or by stopping the current to stop the magnetic force, the valve element 13 moves downward again due to the repulsive force of the urging spring 13c. The path 12 is blocked. When the hydraulic pressure in the arrow direction a is strong, the repulsive force of the urging spring 13c is increased, and a magnetic field that attracts the valve body 13 is generated by the electromagnetic coil 4 so that the valve body 13 is moved downward. Also good.

電磁コイル４をＤＵＴＹ制御電流により励磁し、弁体１３に対する反発力若しくは引力を発生させて、流路１２の開口面積を段階的に変化させる構成をとることもできる。   The electromagnetic coil 4 can be excited by a DUTY control current to generate a repulsive force or attractive force with respect to the valve body 13 so that the opening area of the flow path 12 can be changed stepwise.

図３は、流路１１に対して、矢印方向ｃの向きに、冷却液の圧力が掛かっている場合である。図３（Ａ）においては、弁体１３が流路１２を塞いでいるために、流路１２と流路１１は遮断されている。付勢ばね１３ｃに圧縮ばねを用いた場合は、付勢ばね１３ｃの反発力によって、弁体１３が電磁弁ハウジング１底部に押し付けられて、流路１２を塞いでいる。付勢ばね１３ｃの反発力と矢印方向ｃの液圧によって弁体１３が電磁弁ハウジング１底部に押し付けられている。   FIG. 3 shows the case where the coolant pressure is applied to the flow path 11 in the direction of the arrow c. In FIG. 3A, since the valve body 13 blocks the flow path 12, the flow path 12 and the flow path 11 are blocked. When a compression spring is used as the urging spring 13c, the valve body 13 is pressed against the bottom of the electromagnetic valve housing 1 by the repulsive force of the urging spring 13c, thereby closing the flow path 12. The valve body 13 is pressed against the bottom of the electromagnetic valve housing 1 by the repulsive force of the urging spring 13c and the hydraulic pressure in the arrow direction c.

図３（Ｂ）は、電磁コイル４で上下方向に磁場を発生させて、磁力の反発力によって、弁体１３を上方へ移動させている状態である。このとき、流路１２と流路１１は接続して、流路１１は流入路となり、流路１２は矢印方向ｄへの流出路となる。前記磁力による反発力が矢印方向ｃの液圧と付勢ばね１３ｃの反発力の和より大きくなれば、弁体１３が上方へ移動する。電磁コイル４に流す電流を調整して前記磁力を弱めたり、前記電流を止めて前記磁力を止めたりすることにより、付勢ばね１３ｃの反発力により弁体１３は再び下方へ移動して、流路１２は遮断される。   FIG. 3B shows a state where a magnetic field is generated in the vertical direction by the electromagnetic coil 4 and the valve body 13 is moved upward by the repulsive force of the magnetic force. At this time, the flow path 12 and the flow path 11 are connected, the flow path 11 becomes an inflow path, and the flow path 12 becomes an outflow path in the arrow direction d. When the repulsive force due to the magnetic force becomes larger than the sum of the hydraulic pressure in the arrow direction c and the repulsive force of the biasing spring 13c, the valve body 13 moves upward. By adjusting the current flowing through the electromagnetic coil 4 to weaken the magnetic force, or by stopping the current to stop the magnetic force, the valve element 13 moves downward again due to the repulsive force of the urging spring 13c. The path 12 is blocked.

以上の電磁弁の構成により、自動車の冷却系装置の部品点数の削減、組み付け工数の削減の効果がある。また、前記部品点数の削減により、前記冷却系装置の軽量化、信頼性の向上、省スペース化の効果がある。また、省スペース化により、前記冷却系装置の循環路の短縮化が可能となり冷却機能の効率化が図れる効果がある。   With the above-described configuration of the solenoid valve, there is an effect of reducing the number of parts of the automobile cooling system and reducing the number of assembly steps. Further, the reduction in the number of parts has the effect of reducing the weight of the cooling system, improving the reliability, and saving the space. In addition, the space saving can shorten the circulation path of the cooling system device, and can effectively improve the cooling function.

本発明の電磁弁は、電磁コイル４と電動機用巻き線３１ａ及び３１ｂが接近している特徴がある。しかし、電磁コイル４と前記電動機用巻き線（３１ａと３１ｂ）の巻き軸の属する面が互いに直交しているので、互いの磁気的な干渉は最小に抑えることができるという効果がある。この理由を、図４を使って説明する。図４（Ａ）は、本発明の電磁弁に係る電磁コイル４の巻き線４２である。また、電動機用巻き線のうち、回転軸２２（図４には表示せず）に対して回転対称の関係にある電動機用巻き線３１ａと３１ｂが示されている。   The electromagnetic valve of the present invention is characterized in that the electromagnetic coil 4 and the motor windings 31a and 31b are close to each other. However, since the surfaces to which the winding axes of the electromagnetic coil 4 and the motor windings (31a and 31b) belong are orthogonal to each other, there is an effect that mutual magnetic interference can be minimized. The reason for this will be described with reference to FIG. FIG. 4A shows the winding 42 of the electromagnetic coil 4 according to the electromagnetic valve of the present invention. In addition, among the windings for the motor, windings 31a and 31b for the motor that are rotationally symmetric with respect to the rotating shaft 22 (not shown in FIG. 4) are shown.

ここで、磁気的な干渉とは、電動機用の巻き線が作る磁場によって電磁弁用の巻き線に誘導起電力が生じたり、電磁弁用の巻き線が作る磁場によって電動機用の巻き線に誘導起電力が生じたりすることをいう。   Here, magnetic interference means that an induced electromotive force is generated in the winding for the electromagnetic valve by the magnetic field generated by the winding for the motor, or the induction for the winding for the motor is generated by the magnetic field generated by the winding for the electromagnetic valve. An electromotive force is generated.

図４（Ａ）は、電動機用巻き線３１ａと３１ｂが作る磁場Ｚ１が、電磁弁用巻き線４２に与える影響を示す図である。回転軸に対して回転対称にある巻き線３１ａと３１ｂは同一方向、向きと強さの磁場を発生する。磁場の概略は矢印付の曲線で示している。該矢印は逆向きの場合もある。巻き線４２に誘導起電力を生じさせる磁場は、４２の巻き軸の方向の成分を有する磁場である。しかし、磁場Ｚ１には該方向の成分は少ない。このため、磁場Ｚ１が誘導起電力として、電磁弁用巻き線４２に与える影響は少ない。   FIG. 4A is a diagram showing the influence of the magnetic field Z1 created by the electric motor windings 31a and 31b on the electromagnetic valve winding 42. FIG. The windings 31a and 31b that are rotationally symmetric with respect to the rotation axis generate a magnetic field having the same direction, direction, and strength. The outline of the magnetic field is shown by a curve with an arrow. The arrow may be reversed. The magnetic field that generates the induced electromotive force in the winding 42 is a magnetic field having a component in the direction of the winding axis of 42. However, the magnetic field Z1 has few components in the direction. For this reason, the magnetic field Z1 has little influence on the electromagnetic valve winding 42 as the induced electromotive force.

電動機の巻き線の中、前記３１ａと３１ｂ以外の巻き線も、電磁弁用巻き線４２と直交しているという点で同様であり、電磁弁用巻き線４２に与える影響は少ない。しかし、磁場Ｚ１にある巻き線４２に電流を流すと、該巻き線４２を回転させようとするローレンツ力が作用するため、これに抗する程度に該巻き線４２は固定されていなければならない。   Among the windings of the electric motor, the windings other than 31a and 31b are the same in that they are orthogonal to the solenoid valve winding 42, and the influence on the solenoid valve winding 42 is small. However, when a current is passed through the winding 42 in the magnetic field Z1, a Lorentz force that attempts to rotate the winding 42 acts, so the winding 42 must be fixed to an extent that resists this.

次に、電磁弁用巻き線４２が作る磁場が電動機用巻き線３１ａと３１ｂに与える影響について説明する。図４（Ｂ）に電磁弁用巻き線４２が作る磁場の概略を磁力線Ｚ２ａとＺ２ｂで示す。矢印がそれぞれ逆の場合もあり得る。これらの磁力線は、電磁弁用巻き線４２の巻き軸に対して、回転対称になる。そうすると、電動機用巻き線３１ａと３１ｂには等しい強さで、同方向逆向きの磁場となる。これらは電動機用巻き線３１ａと３１ｂにたいして、それぞれ逆向きの誘導起電力を発生させる。しかしここで、電動機用巻き線３１ａと３１ｂを短絡しておけば、これらの誘導起電力は相殺される。したがって、電磁弁用巻き線４２が作る磁場が電動機用巻き線に影響を与えなくなる。   Next, the influence of the magnetic field created by the solenoid valve winding 42 on the motor windings 31a and 31b will be described. FIG. 4B schematically shows the magnetic field generated by the solenoid valve winding 42 by magnetic lines of force Z2a and Z2b. The arrows may be reversed. These lines of magnetic force are rotationally symmetric with respect to the winding axis of the solenoid valve winding 42. If it does so, it will become a magnetic field of the same direction and a reverse direction with the same intensity | strength in the windings 31a and 31b for motors. These generate induced electromotive forces in opposite directions to the motor windings 31a and 31b, respectively. However, if the motor windings 31a and 31b are short-circuited, these induced electromotive forces are canceled out. Therefore, the magnetic field created by the solenoid valve winding 42 does not affect the motor winding.

以上説明したように、本発明の電磁弁は、電動機用巻き線と接近していながらも、お互いの影響を最小化した配置とする効果がある。この効果により、電磁弁用の電磁コイル４をＤＵＴＹ制御するにも好適な配置といえる。このように、電動機と電磁弁の磁気的な干渉を最小化するには、前記電動機ロータの回転軸の延長直線が、電磁弁の電磁コイル４の巻き線コアを貫く配置であってもよい。   As described above, the electromagnetic valve of the present invention has an effect of minimizing the influence of each other while being close to the winding for the motor. Due to this effect, it can be said that the arrangement is suitable for DUTY control of the electromagnetic coil 4 for the electromagnetic valve. Thus, in order to minimize the magnetic interference between the electric motor and the electromagnetic valve, the extended straight line of the rotating shaft of the electric motor rotor may be disposed through the winding core of the electromagnetic coil 4 of the electromagnetic valve.

本発明の電磁弁を、例えば、電動ウォータバルブとして用いて、前記電動機を電動ウォータポンプとすれば、本発明の電磁弁とこれに隣接する電動機は、自動車の冷却系に適用することができる。   If the electromagnetic valve of the present invention is used as, for example, an electric water valve and the electric motor is an electric water pump, the electromagnetic valve of the present invention and the electric motor adjacent thereto can be applied to a cooling system of an automobile.
