　本開示は、燃料フィルタに関する。 This disclosure relates to fuel filters.
　下記特許文献１には、燃料フィルタに関する技術が開示されている。この燃料フィルタは、フィルタハウジングと、フィルタハウジングの内側に収納されたフィルタエレメントとを備えている。そして、燃料が燃料フィルタ内を通過すると、燃料に含まれる異物がフィルタエレメントによって除去されると共に、燃料に含まれる水分がフィルタハウジングの底側に溜まるようになっている。 The following Patent Document 1 discloses a technique related to a fuel filter. The fuel filter includes a filter housing and a filter element housed inside the filter housing. When the fuel passes through the fuel filter, the foreign matter contained in the fuel is removed by the filter element, and the water contained in the fuel is accumulated on the bottom side of the filter housing.
　また、下記特許文献１に記載の先行技術では、フィルタハウジングの外形が扁平な形状とされており、燃料フィルタの搭載に必要なスペースが鉛直方向に拡大することを抑制することができる。 Further, in the prior art described in Patent Document 1 below, the outer shape of the filter housing is flat, and it is possible to prevent the space required for mounting the fuel filter from expanding in the vertical direction.
　さらに、この燃料フィルタは、フィルタハウジングと、フィルタハウジングの内側に収納されたフィルタエレメントとを備えている。そして、燃料が燃料フィルタ内を通過すると、燃料に含まれる異物がフィルタエレメントによって除去されると共に、燃料に含まれる水分がフィルタハウジングの底側に溜まるようになっている。このため、下記特許文献１に記載の先行技術では、燃料フィルタの所定の方向に寸法を小さくすることができる。 Furthermore, this fuel filter is provided with a filter housing and a filter element housed inside the filter housing. When the fuel passes through the fuel filter, the foreign matter contained in the fuel is removed by the filter element, and the water contained in the fuel is accumulated on the bottom side of the filter housing.

　発明者の詳細な検討の結果、上記特許文献１に記載の先行技術では、フィルタエレメントと水を貯留する部分とが鉛直方向に連なって配置されているため、燃料フィルタの搭載の自由度をより向上させるという点において改善の余地があるとの課題が見出された。 As a result of detailed examination by the inventor, in the prior art described in Patent Document 1, since the filter element and the portion for storing water are arranged in a vertical direction, the degree of freedom in mounting the fuel filter is increased. The issue was found that there is room for improvement in terms of improvement.
　また、発明者は、上記特許文献１に記載の先行技術では、燃料入り口から流入された燃料が、フィルタハウジングの上壁部とフィルタエレメントの上方側に配置された壁の間を通ってフィルタエレメントの下側に流入してから、フィルタエレメント及び通路部材を経由して燃料出口から流出されるため、燃料が通る流路が複雑化するとの課題も見出した。 Further, in the prior art described in Patent Document 1, the inventor has described that the fuel flowing in from the fuel inlet passes between the upper wall portion of the filter housing and the wall arranged on the upper side of the filter element. We have also found a problem that the flow path through which the fuel passes becomes complicated because the fuel flows into the lower side and then flows out from the fuel outlet via the filter element and the passage member.
　開示される目的は、搭載の自由度をより向上させることができる燃料フィルタ並びに燃料から水分及び異物の除去を可能としつつ、燃料が通る流路を単純にすることができる燃料フィルタを得ることである。 The purpose of the disclosure is to obtain a fuel filter that can further improve the degree of freedom of mounting and a fuel filter that can simplify the flow path through which the fuel passes while enabling the removal of water and foreign matter from the fuel. is there.
　本開示の第一の態様に係る燃料フィルタは、燃料タンクと燃料消費機器とを接続する燃料流路に接続され、燃料から分離された水分を貯留すると共に、鉛直方向の寸法が鉛直方向から見た投影面上の最も離れた２点間の距離よりも短い長さに設定された水貯留部と、前記燃料流路に接続され、鉛直方向から見て当該水貯留部と重ならないように配置されると共に、鉛直方向の寸法が鉛直方向から見た投影面上の最も離れた２点間の距離よりも短い長さに設定された異物除去部と、を備えている。 The fuel filter according to the first aspect of the present disclosure is connected to a fuel flow path connecting a fuel tank and a fuel consuming device, stores water separated from the fuel, and has a vertical dimension when viewed from the vertical direction. A water storage unit set to a length shorter than the distance between the two most distant points on the projection surface is connected to the fuel flow path and arranged so as not to overlap the water storage unit when viewed in the vertical direction. At the same time, it is provided with a foreign matter removing portion whose vertical dimension is set to a length shorter than the distance between the two farthest points on the projection surface viewed from the vertical direction.
　上記構成によれば、燃料タンクと燃料消費機器とを接続する燃料流路に水貯留部及び異物除去部が接続されており、水貯留部には、燃料から分離された水分が貯留される。一方、異物除去部では、燃料に含まれた異物が除去される。 According to the above configuration, the water storage unit and the foreign matter removing unit are connected to the fuel flow path connecting the fuel tank and the fuel consuming device, and the water storage unit stores the water separated from the fuel. On the other hand, the foreign matter removing unit removes foreign matter contained in the fuel.
　ところで、燃料フィルタの搭載に必要なスペースが鉛直方向に拡大することを抑制するにあたって、燃料フィルタは、鉛直方向の拡大を抑制可能な構成であることが好ましい。 By the way, in order to prevent the space required for mounting the fuel filter from expanding in the vertical direction, it is preferable that the fuel filter has a configuration capable of suppressing the expansion in the vertical direction.
　ここに開示された燃料フィルタは、水貯留部の鉛直方向の寸法が、水貯留部を鉛直方向から見た投影面上の最も離れた２点間の距離よりも短い長さに設定されており、水貯留部の鉛直方向の寸法が長くなることを抑制することができる。また、異物除去部の鉛直方向の寸法が、異物除去部を鉛直方向から見た投影面上の２点間の距離よりも短い長さに設定されており、異物除去部の鉛直方向の寸法が長くなることを抑制することができる。 In the fuel filter disclosed here, the vertical dimension of the water reservoir is set to be shorter than the distance between the two farthest points on the projection plane when the water reservoir is viewed from the vertical direction. , It is possible to prevent the vertical dimension of the water storage portion from becoming long. Further, the vertical dimension of the foreign matter removing portion is set to be shorter than the distance between two points on the projection surface when the foreign matter removing portion is viewed from the vertical direction, and the vertical dimension of the foreign matter removing portion is set. It is possible to suppress the lengthening.
　しかも、ここに開示された燃料フィルタは、異物除去部が鉛直方向から見て水貯留部と重ならないように配置されている。このため、異物除去部と水貯留部とが鉛直方向に連なって配置されているような構成に比し、搭載の自由度をより向上させることができる。 Moreover, the fuel filter disclosed here is arranged so that the foreign matter removing portion does not overlap with the water storage portion when viewed from the vertical direction. Therefore, the degree of freedom of mounting can be further improved as compared with the configuration in which the foreign matter removing portion and the water storage portion are arranged in a vertical direction.
　本開示の第二の態様に係る燃料フィルタは、燃料が流入される流入口部と、前記流入口部側から流入された燃料から分離された水分を貯留する水貯留部と、前記水貯留部側から流入された前記燃料の異物を除去し、鉛直方向から見て当該水貯留部と重ならないように配置された異物除去部と、前記異物除去部の鉛直方向下側に配置され、当該異物除去部側から流れてくる燃料を流出させる流出口部と、を備えている。 The fuel filter according to the second aspect of the present disclosure includes an inlet portion into which fuel flows, a water storage portion that stores water separated from the fuel flowing in from the inlet portion side, and the water storage portion. The foreign matter removing part of the fuel that has flowed in from the side is removed, and the foreign matter removing part is arranged so as not to overlap with the water storage part when viewed from the vertical direction, and the foreign matter is arranged below the foreign matter removing part in the vertical direction. It is provided with an outlet portion for discharging the fuel flowing from the removal portion side.
　開示される燃料フィルタによると、流入口部側から水貯留部に流入された燃料から分離された水分が、水貯留部に貯留される。また、異物除去部では、水貯留部側から流入された燃料から異物が除去される。そして、燃料は、異物除去部側から流出口部に流れて、当該流出口部から流出される。 According to the disclosed fuel filter, the water separated from the fuel that has flowed into the water storage section from the inflow port side is stored in the water storage section. Further, in the foreign matter removing section, foreign matter is removed from the fuel flowing in from the water storage section side. Then, the fuel flows from the foreign matter removing portion side to the outlet portion and flows out from the outlet portion.
　ところで、燃料フィルタにおいて、水貯留部の機能と異物除去部の機能とを一箇所に集約することが考えられる。例えば、燃料フィルタに室部を設けると共に、当該室部の鉛直方向上側に異物除去部を配置し、燃料と水との比重の違いを利用して当該室部の鉛直方向下側に水を貯留するような構成が考えられる。 By the way, in the fuel filter, it is conceivable to consolidate the function of the water storage part and the function of the foreign matter removal part in one place. For example, the fuel filter is provided with a chamber, and a foreign matter removing portion is arranged on the upper side of the chamber in the vertical direction, and water is stored on the lower side of the chamber in the vertical direction by utilizing the difference in specific gravity between fuel and water. The configuration is conceivable.
　しかしながら、このような構成を採用すると、室部に貯留された水と燃料との混合を避けるため、当該室部の鉛直方向上側に流入口部及び流出口部を配置することが必要となる。また、燃料から分離された水分が再び燃料に混入するのを避けるため、燃料を異物除去部の鉛直方向上側から異物除去部の鉛直方向下側に通すと共に異物除去部を経由した燃料を流出口部に導く流路が必要となる。そして、このような構成では、燃料に燃料フィルタ内を回流させる必要があり、当該燃料の通る流路が複雑になる。 However, if such a configuration is adopted, it is necessary to arrange the inflow port and the outflow port on the upper side in the vertical direction of the room in order to avoid mixing the water stored in the room with the fuel. In addition, in order to prevent the water separated from the fuel from being mixed into the fuel again, the fuel is passed from the upper side in the vertical direction of the foreign matter removing part to the lower side in the vertical direction of the foreign matter removing part, and the fuel passing through the foreign matter removing part is discharged. A flow path leading to the part is required. In such a configuration, it is necessary for the fuel to circulate in the fuel filter, and the flow path through which the fuel passes becomes complicated.
　ここに開示された燃料フィルタは、異物除去部が鉛直方向から見て水貯留部と重ならないように配置されていると共に、異物除去部の鉛直方向下側に流出口部が配置されている。このため、燃料が流入口部から流出口部に向かって流れる過程において、当該燃料が流れる向きが変化することを抑制することができる。その結果、燃料から水分及び異物の除去を可能としつつ、燃料が通る流路を単純にすることができる。 The fuel filter disclosed here is arranged so that the foreign matter removing portion does not overlap with the water storage portion when viewed from the vertical direction, and the outlet portion is arranged below the foreign matter removing portion in the vertical direction. Therefore, it is possible to suppress the change in the direction in which the fuel flows in the process in which the fuel flows from the inlet portion to the outlet portion. As a result, the flow path through which the fuel passes can be simplified while allowing the removal of water and foreign matter from the fuel.
　また、異物除去部が鉛直方向から見て水貯留部と重ならないように配置されている。このため、異物除去部と水貯留部とが鉛直方向において重なって配置されているような構成に比し、燃料フィルタの搭載の自由度をより向上させることができる。 In addition, the foreign matter removal part is arranged so that it does not overlap with the water storage part when viewed from the vertical direction.

It is partitioned in a state of being.
　詳しくは、水貯留部４４内に区画部９０が配置されることで、水貯留部４４内の空間は、第３方向において２つに区画されている。すなわち、区画部９０の上壁部９０Ａ及び周壁部９０Ｂは、水貯留部４４内の第３方向上側の空間と第３方向下側の空間との境界部として機能している。 Specifically, by arranging the partition 90 in the water storage 44, the space in the water storage 44 is divided into two in the third direction. That is, the upper wall portion 90A and the peripheral wall portion 90B of the partition portion 90 function as a boundary portion between the space on the upper side in the third direction and the space on the lower side in the third direction in the water storage portion 44.
　また、区画部９０の内側も複数の部屋に区画されている。すなわち、第１方向仕切壁部９０Ｃは、区画部９０内の空間を第２方向において２つに区画しており、第２方向仕切壁部９０Ｄは、区画部９０内の空間を第１方向において３つに区画している。つまり、区画部９０内の空間は、第１方向仕切壁部９０Ｃ及び第２方向仕切壁部９０Ｄによって６つに区画されている。 In addition, the inside of the compartment 90 is also partitioned into a plurality of rooms. That is, the first-direction partition wall portion 90C divides the space in the partition portion 90 into two in the second direction, and the second-direction partition wall portion 90D divides the space in the partition portion 90 in the first direction. It is divided into three parts. That is, the space in the partition portion 90 is divided into six by the first-direction partition wall portion 90C and the second-direction partition wall portion 90D.
　また、上壁部９０Ａの一般部９０Ａ２には、第３方向から見て上板部８６の外周側の周縁部に沿うように、複数の貫通部９８が形成されており、区画部９０の外側と内側とが貫通部９８を介して連通された状態となっている。 Further, in the general portion 90A2 of the upper wall portion 90A, a plurality of penetrating portions 98 are formed along the peripheral edge portion on the outer peripheral side of the upper plate portion 86 when viewed from the third direction, and the outer side of the partition portion 90 is formed. And the inside are in a state of being communicated with each other via the penetrating portion 98.
　なお、ハウジング８０には、内周板部８６Ａ、流出筒部８８及び中央部９０Ａ１に沿う補強リブ部１００が、流出筒部８８の周方向の複数箇所に設けられている。 The housing 80 is provided with an inner peripheral plate portion 86A, an outflow cylinder portion 88, and reinforcing rib portions 100 along the central portion 90A1 at a plurality of locations in the circumferential direction of the outflow cylinder portion 88.
　一方、凝集エレメント８２は、親水性及び弾性を有する繊維等で構成されると共に、その外形が第３方向から見てオーバル形状（例えば、角丸長方形状）とされたリング状とされており、ハウジング８０によって保持されている。詳しくは、凝集エレメント８２の第３方向上側の面は、外周板部８６Ｃで保持されており、凝集エレメント８２の第３方向下側の面は、一般部９０Ａ２で保持されており、凝集エレメント８２の内周面８２Ａは、縦板部８６Ｂ及び中央部９０Ａ１で保持されている。 On the other hand, the agglomerating element 82 is composed of hydrophilic and elastic fibers and the like, and has a ring shape having an oval shape (for example, a rounded rectangular shape) when viewed from a third direction. It is held by the housing 80. Specifically, the upper surface of the aggregating element 82 in the third direction is held by the outer peripheral plate portion 86C, and the lower surface of the aggregating element 82 in the third direction is held by the general portion 90A2. The inner peripheral surface 82A of the above is held by the vertical plate portion 86B and the central portion 90A1.
　なお、縦板部８６Ｂ及び中央部９０Ａ１における凝集エレメント８２側の面には、それぞれ複数の突起部１０１が形成されており、凝集エレメント８２の内周面８２Ａと縦板部８６Ｂ及び中央部９０Ａ１とが点接触するようになっている。つまり、凝集エレメント８２の内周面８２Ａと縦板部８６Ｂ及び中央部９０Ａ１との間には、燃料が流入可能な隙間が確保された状態となっている。 A plurality of protrusions 101 are formed on the surfaces of the vertical plate portion 86B and the central portion 90A1 on the aggregation element 82 side, respectively, and the inner peripheral surface 82A of the aggregation element 82, the vertical plate portion 86B, and the central portion 90A1 Are in point contact. That is, a gap is secured between the inner peripheral surface 82A of the cohesive element 82 and the vertical plate portion 86B and the central portion 90A1 so that fuel can flow in.
　また、凝集エレメント８２は、微小な水滴を捕捉可能とされており、水分を含んだ燃料が凝集エレメント８２を通過すると、凝集エレメント８２の外周面８２Ｂにおいて、微小な水滴が大きな水滴となって流下するようになっている。 Further, the agglomeration element 82 is capable of capturing minute water droplets, and when the fuel containing water passes through the agglomeration element 82, the minute water droplets flow down as large water droplets on the outer peripheral surface 82B of the agglomeration element 82. It is designed to do.
　上記のように構成された水捕集器７８では、図６に示されるように、蓋部３８の開口部７６側から貫通部９４を通って流出筒部８８の外側に流出した燃料が、凝集エレメント８２を通過することで、水が燃料から分離されるようになっている。 In the water collector 78 configured as described above, as shown in FIG. 6, the fuel that has flowed out from the opening 76 side of the lid 38 through the penetrating portion 94 to the outside of the outflow cylinder 88 is aggregated. By passing through the element 82, the water is separated from the fuel.
　そして、凝集エレメント８２の外周面８２Ｂを流下した水は、ハウジング８０の貫通部９８を通って水貯留部４４の第３方向下側に溜まるようになっている。なお、水貯留部４４内の水位が隔壁部３６Ｈに設けられた水位検知センサに達すると、この水位検知センサからの信号が図示しないインジケータに出力されて、このインジケータには、水貯留部４４内の水位の上昇を示す警告が表示されるようになっている。 Then, the water flowing down the outer peripheral surface 82B of the cohesive element 82 passes through the penetrating portion 98 of the housing 80 and collects on the lower side in the third direction of the water storage portion 44. When the water level in the water storage unit 44 reaches the water level detection sensor provided in the partition wall portion 36H, a signal from the water level detection sensor is output to an indicator (not shown), and the indicator is in the water storage unit 44. A warning is displayed to indicate that the water level is rising.
　また、水貯留部４４に溜まった水は、排水プラグ６６を排出口部６４から抜くことで、水貯留部４４内から排出することが可能である。なお、水捕集器７８は、水の捕集に用いられない継手部８４を除いて、水貯留部４４の内側に納まっている。 Further, the water accumulated in the water storage unit 44 can be discharged from the water storage unit 44 by pulling out the drain plug 66 from the discharge port portion 64. The water collector 78 is housed inside the water storage unit 44, except for the joint portion 84 that is not used for collecting water.
　次に、図９及び図１０を主に用いて、異物除去室部４６の内側に配置された異物捕集器１０２の構成について説明することとする。異物捕集器１０２は、異物除去部側ハウジングとしての樹脂製のハウジング１０４と、異物除去エレメント１０６とを含んで構成されている。 Next, the configuration of the foreign matter collector 102 arranged inside the foreign matter removing chamber 46 will be described mainly using FIGS. 9 and 10. The foreign matter collector 102 is configured to include a resin housing 104 as a foreign matter removing portion side housing and a foreign matter removing element 106.
　ハウジング１０４は、上板部１０８、接続部１１０及び周壁部１１１を含んで構成されており、全体的には第３方向下側が開放された箱状とされている。詳しくは、上板部１０８は、ハウジング１０４の第３方向上側の部分を構成すると共に、頂壁部１０８Ａ、一対の傾斜壁部１０８Ｂ及び一対の傾斜壁部１０８Ｃを含んで、その外形が四角錐台状とされている。つまり、上板部１０８は、第３方向から見て矩形状とされている。また、上板部１０８の下面部１０８Ｄには、下面部１０８Ｄから第３方向下側に突出した複数の突起部１０８Ｅが設けられている。 The housing 104 includes an upper plate portion 108, a connecting portion 110, and a peripheral wall portion 111, and has a box shape in which the lower side in the third direction is open as a whole. Specifically, the upper plate portion 108 constitutes the upper portion of the housing 104 in the third direction, and includes the top wall portion 108A, the pair of inclined wall portions 108B, and the pair of inclined wall portions 108C, and the outer shape thereof is a quadrangular pyramid. It is trapezoidal. That is, the upper plate portion 108 has a rectangular shape when viewed from the third direction. Further, the lower surface portion 108D of the upper plate portion 108 is provided with a plurality of protrusions 108E protruding downward in the third direction from the lower surface portion 108D.
　接続部１１０は、軸方向を第３方向とされた円筒状とされていると共に、頂壁部１０８Ａの中央部から第３方向上側に延出されている。この接続部１１０の外周面には、接続部１１０の周方向に延びる溝部１１２が形成されており、溝部１１２には、シール部材１１３が嵌め込まれている。そして、接続部１１０は、第３方向下側から蓋部３８の液溜め部３８Ｄに挿入されている。つまり、ハウジング１０４は、第３方向上側において燃料配管２４側に連通された状態となっている。 The connecting portion 110 has a cylindrical shape with the axial direction as the third direction, and extends upward from the central portion of the top wall portion 108A in the third direction. A groove 112 extending in the circumferential direction of the connection 110 is formed on the outer peripheral surface of the connection 110, and the seal member 113 is fitted in the groove 112. Then, the connecting portion 110 is inserted into the liquid reservoir portion 38D of the lid portion 38 from the lower side in the third direction. That is, the housing 104 is in a state of communicating with the fuel pipe 24 side on the upper side in the third direction.
　周壁部１１１は、上板部１０８の周縁部から第３方向下側に延びる角筒状とされていると共に、その下端部が、ハウジング本体部３６の底壁部３６Ｅにおける複数箇所に設けられた突起部１１４に支持されている。なお、周壁部１１１の下端部は、底壁部３６Ｅに対して所定の間隔があけられた位置に位置している。 The peripheral wall portion 111 has a square tubular shape extending downward in the third direction from the peripheral edge portion of the upper plate portion 108, and its lower end portions are provided at a plurality of positions on the bottom wall portion 36E of the housing main body portion 36. It is supported by the protrusion 114. The lower end of the peripheral wall portion 111 is located at a position at a predetermined distance from the bottom wall portion 36E.
　一方、異物除去エレメント１０６は、例えば、濾紙やポリエステル系不織布等で構成されると共に、複数のプリーツ部１０６Ａを備えたプリーツ型とされており、燃料が通過することで、燃料に含まれた埃等の異物を除去可能とされている。なお、異物除去エレメント１０６は、所定量の水分を燃料から除去することも可能とされている。 On the other hand, the foreign matter removing element 106 is made of, for example, filter paper, polyester-based non-woven fabric, or the like, and is a pleated type having a plurality of pleated portions 106A. When the fuel passes through, the dust contained in the fuel is contained. It is possible to remove foreign substances such as. The foreign matter removing element 106 is also capable of removing a predetermined amount of water from the fuel.
　この異物除去エレメント１０６は、その外形が直方体状とされており、ハウジング１０４の内側に収容されると共に、ハウジング１０４の突起部１０８Ｅに図示しない接着剤等による接合部によって接合されている。つまり、ハウジング１０４の上板部１０８と異物除去エレメント１０６とは、点接触した状態となっており、上板部１０８と異物除去エレメント１０６との間には、燃料が流入可能な隙間が確保された状態となっている。 The foreign matter removing element 106 has a rectangular parallelepiped outer shape, is housed inside the housing 104, and is joined to the protrusion 108E of the housing 104 by a joint portion such as an adhesive (not shown). That is, the upper plate portion 108 of the housing 104 and the foreign matter removing element 106 are in a point contact state, and a gap through which fuel can flow is secured between the upper plate portion 108 and the foreign matter removing element 106. It is in a state of being.
　上記のように構成された異物捕集器１０２では、水貯留部４４側から隙間６８通って異物除去室部４６側に流入した燃料が、上板部１０８の上面に沿って流れると共に、ハウジング１０４の周囲から異物除去エレメント１０６の第３方向下側に回り込んで異物除去エレメント１０６を第３方向下側から上側に向かって通り抜けるようになっている。そして、異物除去エレメント１０６を通り抜けた燃料は、埃等の異物が除去された状態で、液溜め部３８Ｄ及び流出口部３８Ｅを経て燃料配管２４に流出されるようになっている。 In the foreign matter collector 102 configured as described above, the fuel that has flowed from the water storage portion 44 side through the gap 68 to the foreign matter removal chamber portion 46 side flows along the upper surface of the upper plate portion 108 and the housing 104. The foreign matter removing element 106 wraps around to the lower side in the third direction and passes through the foreign matter removing element 106 from the lower side to the upper side in the third direction. Then, the fuel that has passed through the foreign matter removing element 106 flows out to the fuel pipe 24 through the liquid reservoir portion 38D and the outlet portion 38E in a state where foreign matter such as dust is removed.
　（本実施形態の作用及び効果）
　次に、本実施形態の作用及び効果を説明する。 (Action and effect of this embodiment)
Next, the operation and effect of this embodiment will be described.
　本実施形態では、図１及び図１１に示されるように、燃料タンク１６とインジェクタ２２とを接続する燃料配管２４に水貯留部４４及び異物除去部３４が接続されており、水貯留部４４には、燃料から分離された水分が貯留される。一方、異物除去部３４では、燃料に含まれた異物が除去される。 In the present embodiment, as shown in FIGS. 1 and 11, a water storage unit 44 and a foreign matter removing unit 34 are connected to the fuel pipe 24 connecting the fuel tank 16 and the injector 22, and the water storage unit 44 is connected to the water storage unit 44. Stores the water separated from the fuel. On the other hand, the foreign matter removing unit 34 removes the foreign matter contained in the fuel.
　ところで、燃料フィルタ１０の搭載に必要なスペースが第３方向に拡大することを抑制するにあたって、燃料フィルタ１０は、第３方向の拡大を抑制可能な構成であることが好ましい。 By the way, in order to suppress the expansion of the space required for mounting the fuel filter 10 in the third direction, it is preferable that the fuel filter 10 has a configuration capable of suppressing the expansion in the third direction.
　ここで、本実施形態では、水貯留部４４の第３方向の寸法Ｈ１が、水貯留部４４を第３方向から見た投影面上の最も離れた２点間の距離よりも短い長さに設定されており、水貯留部４４の寸法Ｈ１が長くなることを抑制することができる。また、異物除去部３４の第３方向の寸法Ｈ２が、異物除去部３４を第３方向から見た投影面上の２点間の距離よりも短い長さに設定されており、寸法Ｈ２が長くなることを抑制することができる。 Here, in the present embodiment, the dimension H1 of the water storage unit 44 in the third direction is shorter than the distance between the two farthest points on the projection plane when the water storage unit 44 is viewed from the third direction. It is set, and it is possible to prevent the dimension H1 of the water storage unit 44 from becoming long. Further, the dimension H2 of the foreign matter removing portion 34 in the third direction is set to a length shorter than the distance between two points on the projection surface when the foreign matter removing portion 34 is viewed from the third direction, and the dimension H2 is long. It can be suppressed.
　しかも、本実施形態では、異物除去部３４が第３方向から見て水貯留部４４と重ならないように配置されている。このため、異物除去部３４と水貯留部４４とが第３方向に連なって配置されているような構成に比し、燃料フィルタ１０の搭載の自由度をより向上させることができる。 Moreover, in the present embodiment, the foreign matter removing portion 34 is arranged so as not to overlap with the water storage portion 44 when viewed from the third direction. Therefore, the degree of freedom in mounting the fuel filter 10 can be further improved as compared with the configuration in which the foreign matter removing portion 34 and the water storage portion 44 are arranged in a row in the third direction.
　また、本実施形態では、水貯留部４４及び異物除去部３４が外側ハウジング２８に一体に設けられており、水貯留部４４と異物除去部３４とが別体とされているような構成に比し、燃料フィルタ１０の取付作業を簡略化することができる。 Further, in the present embodiment, the water storage unit 44 and the foreign matter removing unit 34 are integrally provided in the outer housing 28, and the water storage unit 44 and the foreign matter removing unit 34 are separated from each other. However, the installation work of the fuel filter 10 can be simplified.
　また、本実施形態では、図６に示されるように、外側ハウジング２８に水分離部３２が設けられており、水分離部３２によって燃料に混入した水分が燃料から分離される。 Further, in the present embodiment, as shown in FIG. 6, a water separation unit 32 is provided in the outer housing 28, and the water separation unit 32 separates the water mixed in the fuel from the fuel.
　詳しくは、水分離部３２は、水貯留部４４の内側に配置された水捕集器７８と、外側ハウジング２８に設けられた障壁部３６Ｄとを備えている。また、水捕集器７８は、凝集エレメント８２と、凝集エレメント８２を保持するハウジング８０とを含んで構成されている。 Specifically, the water separation unit 32 includes a water collector 78 arranged inside the water storage unit 44 and a barrier portion 36D provided in the outer housing 28. Further, the water collector 78 is configured to include an aggregating element 82 and a housing 80 for holding the aggregating element 82.
　そして、燃料がハウジング８０の流出筒部８８の貫通部９４を通って凝集エレメント８２を通過するときに、燃料に含まれた水分は、凝集エレメント８２によって凝集されると共に、水貯留部４４の第３方向下側に溜まる。 Then, when the fuel passes through the aggregating element 82 through the penetrating portion 94 of the outflow cylinder portion 88 of the housing 80, the water contained in the fuel is agglomerated by the aggregating element 82 and the water storage portion 44 is the first. It collects on the lower side in three directions.
　また、水貯留部４４は、燃料配管２４において異物除去部３４の上流側に配置されており、水貯留部４４と異物除去部３４との境界部には、障壁部３６Ｄが配置されている。これにより、水貯留部４４に貯留された水の異物除去部３４側への侵入が規制され、ひいては燃料から分離された水が再度燃料に混入することを抑制することができる。 Further, the water storage unit 44 is arranged on the upstream side of the foreign matter removing unit 34 in the fuel pipe 24, and the barrier portion 36D is arranged at the boundary portion between the water storage unit 44 and the foreign matter removing unit 34. As a result, the invasion of the water stored in the water storage unit 44 to the foreign matter removing unit 34 side is restricted, and it is possible to prevent the water separated from the fuel from being mixed into the fuel again.
　しかも、障壁部３６Ｄは、ハウジング本体部３６の底壁部３６Ｅから第３方向上側に延びると共に、障壁部３６Ｄの上端部３６Ｄ１と蓋部３８の天板部３８Ａとの間には隙間があいている。このため、燃料よりも比重が大きい水は、障壁部３６Ｄを越えることなく水貯留部４４に留まる。一方、燃料は、障壁部３６Ｄの第３方向上側において、水貯留部４４側から異物除去部３４側へと流入する。したがって、本実施形態では、燃料フィルタ１０を扁平形状としつつ、燃料から水分が除去される確度を高めることができる。 Moreover, the barrier portion 36D extends upward from the bottom wall portion 36E of the housing main body portion 36 in the third direction, and there is a gap between the upper end portion 36D1 of the barrier portion 36D and the top plate portion 38A of the lid portion 38. There is. Therefore, the water having a specific gravity higher than that of the fuel stays in the water storage portion 44 without exceeding the barrier portion 36D. On the other hand, the fuel flows from the water storage portion 44 side to the foreign matter removing portion 34 side on the upper side of the barrier portion 36D in the third direction. Therefore, in the present embodiment, it is possible to increase the probability that water is removed from the fuel while making the fuel filter 10 flat.
　ところで、燃料フィルタ１０が搭載されている車両が走行している状態において、路面の傾斜や車両の加速度等の影響を受けて、水貯留部４４の内側に貯留された水が変位することが考えられる。そして、水の変位の大きさによっては、水貯留部４４の内側の水が異物除去部３４側に侵入することが考えられる。 By the way, it is conceivable that the water stored inside the water storage unit 44 is displaced due to the influence of the inclination of the road surface, the acceleration of the vehicle, etc. while the vehicle on which the fuel filter 10 is mounted is running. Be done. Then, depending on the magnitude of the displacement of the water, it is conceivable that the water inside the water storage portion 44 invades the foreign matter removing portion 34 side.
　ここで、本実施形態では、ハウジング８０が区画部９０を備えており、区画部９０によって、水貯留部４４における底壁部３６Ｅ側の部分が、底壁部３６Ｅ側が連通された状態で区画されている。また、水貯留部４４は、隔壁部３６Ｈによって、第１方向において２つに区画されている。 Here, in the present embodiment, the housing 80 includes a compartment 90, and the compartment 90 partitions the portion of the water storage portion 44 on the bottom wall portion 36E side in a state in which the bottom wall portion 36E side is communicated with each other. ing. Further, the water storage portion 44 is divided into two in the first direction by the partition wall portion 36H.
　このため、本実施形態では、水貯留部４４における底壁部３６Ｅ側の部分に底壁部３６Ｅ側が連通された複数の室部が形成された状態となり、水貯留部４４に貯留される水は、これらの複数の室部に分配されることとなる。 Therefore, in the present embodiment, a plurality of chambers in which the bottom wall portion 36E side is communicated with each other are formed in the portion of the water storage portion 44 on the bottom wall portion 36E side, and the water stored in the water storage portion 44 is , It will be distributed to these multiple chambers.
　つまり、本実施形態では、燃料フィルタ１０が路面の傾斜や車両の加速度等の影響受けている状態において、水貯留部４４内の水は、区画部９０によって形成された各室部内において変位することとなる。その結果、燃料フィルタ１０が路面の傾斜や車両の加速度等の影響受けている状態において、水貯留部４４内の水の分布に偏りが生じることを抑制し、ひいては水貯留部４４内の水位が局部的に上昇することを抑制することができる。 That is, in the present embodiment, when the fuel filter 10 is affected by the inclination of the road surface, the acceleration of the vehicle, or the like, the water in the water storage portion 44 is displaced in each chamber formed by the compartment 90. It becomes. As a result, when the fuel filter 10 is affected by the inclination of the road surface, the acceleration of the vehicle, etc., it is possible to suppress the uneven distribution of water in the water storage unit 44, and as a result, the water level in the water storage unit 44 becomes higher. It is possible to suppress the local rise.
　しかも、本実施形態では、障壁部３６Ｄ及び隔壁部３６Ｈによって区画された各室部によって、水溜容積を確保することができ、その結果、水貯留部４４から水が流出することを抑制することができる。 Moreover, in the present embodiment, the volume of the water reservoir can be secured by each of the chambers partitioned by the barrier portion 36D and the partition wall portion 36H, and as a result, the outflow of water from the water storage portion 44 can be suppressed. it can.
　したがって、本実施形態では、燃料フィルタ１０が搭載されている車両が走行している状態において、水貯留部４４の内側の水が異物除去部３４側に侵入することをより抑制することができる。 Therefore, in the present embodiment, it is possible to further prevent the water inside the water storage unit 44 from entering the foreign matter removing unit 34 side while the vehicle on which the fuel filter 10 is mounted is running.
　また、本実施形態では、外側ハウジング２８に設けられた異物除去室部４６の内側に異物捕集器１０２が配置されており、異物捕集器１０２は、異物除去エレメント１０６とハウジング１０４とを含んで構成されている。 Further, in the present embodiment, the foreign matter collector 102 is arranged inside the foreign matter removing chamber 46 provided in the outer housing 28, and the foreign matter collector 102 includes the foreign matter removing element 106 and the housing 104.

　詳しくは、ハウジング１０４は、図１０にも示されるように、第３方向下側が開放された箱状とされると共に、異物除去エレメント１０６を収容している。また、ハウジング１０４は、第３方向上側において燃料配管２４に連通されている。このため、本実施形態では、燃料が異物除去エレメント１０６の中央側のみでなく異物除去エレメント１０６の周縁部からも流入されるため、異物除去エレメント１０６において異物が除去される箇所に偏りが生じることを抑制することができる。 Specifically, as shown in FIG. 10, the housing 104 has a box shape with the lower side open in the third direction and houses the foreign matter removing element 106. Further, the housing 104 communicates with the fuel pipe 24 on the upper side in the third direction. Therefore, in the present embodiment, the fuel flows not only from the central side of the foreign matter removing element 106 but also from the peripheral edge portion of the foreign matter removing element 106, so that the foreign matter removing element 106 is biased at the place where the foreign matter is removed. Can be suppressed.
　また、水貯留部４４側から隙間６８を通って異物除去室部４６内に流れた燃料は、上板部１０８の上面に沿って流れると共に、第３方向から見て矩形状とされた周壁部１１１から流れ落ちて、異物除去エレメント１０６の下面から上面に向かって流れる。このため、燃料中の空気が異物除去エレメント１０６に留まることを抑制することができ、その結果、異物除去室部４６内の空気の排出が促される。 Further, the fuel that has flowed from the water storage portion 44 side through the gap 68 into the foreign matter removing chamber portion 46 flows along the upper surface of the upper plate portion 108, and is a peripheral wall portion that is rectangular when viewed from the third direction. It flows down from 111 and flows from the lower surface to the upper surface of the foreign matter removing element 106. Therefore, it is possible to prevent the air in the fuel from staying in the foreign matter removing element 106, and as a result, the discharge of the air in the foreign matter removing chamber 46 is promoted.
　さらに、ハウジング１０４の上板部１０８は、その外形が四角錐台状とされており、ハウジング１０４の内側に侵入した空気が上板部１０８の傾斜壁部１０８Ｂ、１０８Ｃに沿って流れやすくなっている。加えて、ハウジング１０４は、蓋部３８に設けられた液溜め部３８Ｄに接続されているため、傾斜壁部１０８Ｂ、１０８Ｃに沿って流れてきた空気を液溜め部３８Ｄに集約させて流すことができる。 Further, the upper plate portion 108 of the housing 104 has a quadrangular pyramid shape in its outer shape, so that air that has entered the inside of the housing 104 easily flows along the inclined wall portions 108B and 108C of the upper plate portion 108. There is. In addition, since the housing 104 is connected to the liquid reservoir 38D provided in the lid 38, the air flowing along the inclined wall portions 108B and 108C can be collected and flowed in the liquid reservoir 38D. it can.

　ところで、ヒータ３０が、外側ハウジング２８における第３方向上側の部分に配置されていると、ヒータ３０の内側に空気が溜まり、ヒータ３０による燃料の加熱効率の低下を招くことが考えられる。 By the way, if the heater 30 is arranged in the upper portion of the outer housing 28 in the third direction, it is considered that air is accumulated inside the heater 30 and the heating efficiency of the fuel by the heater 30 is lowered.
　ここで、本実施形態では、ヒータ３０を収容するヒータ収容部４２が、ハウジング本体部３６の第１方向一方側でかつ第３方向下側の部分に設けられている。また、ヒータ３０を通った燃料が、導入流路部７２及び上側流路部３８Ｃを通って第３方向上側から水貯留部４４側に流入するようになっている。 Here, in the present embodiment, the heater accommodating portion 42 accommodating the heater 30 is provided on one side of the housing main body 36 in the first direction and on the lower portion in the third direction. Further, the fuel that has passed through the heater 30 flows into the water storage portion 44 side from the upper side in the third direction through the introduction flow path portion 72 and the upper flow path portion 38C.
　このため、本実施形態では、ヒータ３０の内側に空気が留まることを抑制し、ヒータ３０による燃料の加熱効率を確保することができる。 Therefore, in the present embodiment, it is possible to suppress the air from staying inside the heater 30 and secure the heating efficiency of the fuel by the heater 30.
　また、本実施形態では、水捕集器７８の一部を構成するハウジング８０に設けられた継手部８４と縦板部８６Ｂとの間に凹部９２が形成されている。このため、蓋部３８とハウジング８０との溶着時において、蓋部３８に設けられた外側枠部３８Ｈと縦板部８６Ｂとの干渉を抑制することができる。また、ハウジング８０で保持可能な凝集エレメント８２の第３方向の寸法を確保することができる。 Further, in the present embodiment, a recess 92 is formed between the joint portion 84 provided in the housing 80 forming a part of the water collector 78 and the vertical plate portion 86B. Therefore, when the lid portion 38 and the housing 80 are welded together, interference between the outer frame portion 38H provided on the lid portion 38 and the vertical plate portion 86B can be suppressed. In addition, the dimensions of the cohesive element 82 that can be held by the housing 80 in the third direction can be secured.
　加えて、本実施形態では、ハウジング本体部３６の外周側に、ハウジング本体部３６の周縁部に沿って継手部３６Ａが設けられている。このため、継手部３６Ａがハウジング本体部３６の内側に設けられている構成に比し、外側ハウジング２８の容積を確保することができる。 In addition, in the present embodiment, a joint portion 36A is provided on the outer peripheral side of the housing main body portion 36 along the peripheral edge portion of the housing main body portion 36. Therefore, the volume of the outer housing 28 can be secured as compared with the configuration in which the joint portion 36A is provided inside the housing main body portion 36.

　本実施形態に係る燃料フィルタ１９０は、基本的に第１実施形態に係る燃料フィルタ１０と同様の構成とされている。しかしながら、本実施形態では、ヒータ３０が外側ハウジング１９２の蓋部１９４に取り付けられている点並びに蓋部１９４に流入口部１９４Ａ及び流出口部３８Ｅと同様の構成とされた流出口部１９４Ｂが設けられている点が上述した第１実施形態と異なっている。 The fuel filter 190 according to the present embodiment has basically the same configuration as the fuel filter 10 according to the first embodiment. However, in the present embodiment, the heater 30 is attached to the lid portion 194 of the outer housing 192, and the lid portion 194 is provided with the inlet portion 194A and the outlet portion 194B having the same configuration as the outlet portion 38E. The point is different from the first embodiment described above.
　具体的には、蓋部１９４には、その第１方向一方側の部分にヒータ収容部１９４Ｃが設けられている。このヒータ収容部１９４Ｃは、第２方向に延びると共に両端部が開放された円筒状とされており、蓋部１９４の天板部１９４Ｄの第３方向上側に天板部１９４Ｄと一体に設けられている。 Specifically, the lid portion 194 is provided with a heater accommodating portion 194C on one side of the lid portion 194 in the first direction. The heater accommodating portion 194C has a cylindrical shape that extends in the second direction and has both ends open, and is provided integrally with the top plate portion 194D on the upper side of the top plate portion 194D of the lid portion 194 in the third direction. There is.
　そして、ヒータ収容部１９４Ｃには、第２方向一方側からヒータ３０が取り付けられており、第２方向他方側から空気抜きプラグ７４が取り付けられている。また、ヒータ収容部１９４Ｃは、その中央部において開口部７６を介して水貯留部４４と連通されている。なお、図２２には、ヒータ３０を図示していない。 Then, the heater 30 is attached to the heater accommodating portion 194C from one side in the second direction, and the air vent plug 74 is attached from the other side in the second direction. Further, the heater accommodating portion 194C is communicated with the water storage portion 44 via the opening 76 at the central portion thereof. Note that FIG. 22 does not show the heater 30.
　一方、流入口部１９４Ａは、ヒータ収容部１９４Ｃの第２方向一方側の端部から第１方向一方側に延びる円筒状とされており、ヒータ収容部１９４Ｃと連通されている。なお、流入口部１９４Ａの先端部には、燃料タンク１６側に繋がる燃料配管２４が接続されている。 On the other hand, the inflow port portion 194A has a cylindrical shape extending from the end portion on one side of the heater accommodating portion 194C to one side in the first direction, and is communicated with the heater accommodating portion 194C. A fuel pipe 24 connected to the fuel tank 16 side is connected to the tip of the inflow port 194A.
　このような構成によれば、基本的に上述した第１実施形態と同様の作用並びに効果を奏する。また、本実施形態では、外側ハウジング１９２が、ハウジング本体部３６と蓋部１９４との２つの部品で構成されると共に、蓋部１９４に燃料の流入口部１９４Ａ及び流出口部１９４Ｂが設けられている。このため、車種によって燃料の流入口部１９４Ａ及び流出口部１９４Ｂの向き等が変更されたとしても、ハウジング本体部３６を共通部品として用いることができ、その結果、外側ハウジング１９２のバリエーション展開が容易となる。 According to such a configuration, basically the same actions and effects as those of the above-described first embodiment are obtained. Further, in the present embodiment, the outer housing 192 is composed of two parts, a housing main body portion 36 and a lid portion 194, and the lid portion 194 is provided with a fuel inlet portion 194A and an outlet portion 194B. There is. Therefore, even if the directions of the fuel inlet portion 194A and the outlet portion 194B are changed depending on the vehicle model, the housing main body portion 36 can be used as a common part, and as a result, the variation of the outer housing 192 can be easily developed. It becomes.
　また、本実施形態では、ヒータ３０が配置される箇所が蓋部１９４に設けられているため、上述した第１実施形態に比し、水貯留部４４の容量の拡大を図ることができる。 Further, in the present embodiment, since the portion where the heater 30 is arranged is provided in the lid portion 194, the capacity of the water storage portion 44 can be expanded as compared with the first embodiment described above.
　＜第９実施形態の変形例＞
　以下、図２３及び図２４を用いて、第９実施形態に係る燃料フィルタの変形例について説明する。本変形例では、ヒータ３０を備えておらず、これに伴い蓋部１９４にヒータ収容部１９４Ｃが設けられていない。 <Modified example of the ninth embodiment>
Hereinafter, a modified example of the fuel filter according to the ninth embodiment will be described with reference to FIGS. 23 and 24. In this modification, the heater 30 is not provided, and the heater accommodating portion 194C is not provided on the lid portion 194 accordingly.
　このような構成によれば、燃料フィルタ１９０が使用される条件に応じて、燃料フィルタ１９０の構成を簡略化することができる。なお、上述した各実施形態並びに後述する各実施形態においても仕様等に応じて適宜ヒータ３０を設けない構成としてもよい。 According to such a configuration, the configuration of the fuel filter 190 can be simplified according to the conditions in which the fuel filter 190 is used. In each of the above-described embodiments and the following-described embodiments, the heater 30 may not be provided as appropriate according to the specifications and the like.
　また、このような構成においても、図２３に示されるように、車種によって燃料の流入口部１９４Ａの向きと流出口部１９４Ｂの向きとが異なる場合がある。しかしながら、蓋部１９４のみを変更してハウジング本体部３６を共通部品とすることができるため、外側ハウジング１９２のバリエーション展開が容易となる。なお、図２３には、流出口部１９４Ｂの向きが異なる構成の一例を点線で示している。 Further, even in such a configuration, as shown in FIG. 23, the direction of the fuel inlet portion 194A and the orientation of the outlet portion 194B may differ depending on the vehicle type. However, since only the lid portion 194 can be changed to make the housing main body portion 36 a common component, it becomes easy to develop variations of the outer housing 192. In FIG. 23, an example of a configuration in which the direction of the outlet portion 194B is different is shown by a dotted line.
　さらに、流入口部１９４Ａがハウジング本体部３６に設けられているような構成であっても、蓋部１９４において流出口部１９４Ｂの方向の設計変更は容易であるため、外側ハウジング１９２のバリエーション展開に寄与する。 Further, even if the inflow port portion 194A is provided in the housing main body portion 36, it is easy to change the design of the direction of the outflow port portion 194B in the lid portion 194. Contribute.
　＜第１０実施形態＞
　以下、図２５及び図２６を用いて、開示される燃料フィルタの第１０実施形態について説明する。なお、上述した第１実施形態と同一構成部分については同一番号を付してその説明を省略する。 <10th Embodiment>
Hereinafter, the tenth embodiment of the disclosed fuel filter will be described with reference to FIGS. 25 and 26. The same components as those in the above-described first embodiment are designated by the same numbers, and the description thereof will be omitted.
　本実施形態に係る燃料フィルタ２００は、基本的に第１実施形態に係る燃料フィルタ１０と同様の構成とされている。しかしながら、本実施形態では、凝集エレメント８２を備えておらず、障壁部３６Ｄ及び水貯留部側ハウジングとしての樹脂製のハウジング２０２で水分離部２０３が構成されている点が上述した第１実施形態と異なっている。 The fuel filter 200 according to the present embodiment has basically the same configuration as the fuel filter 10 according to the first embodiment. However, in the first embodiment described above, the first embodiment described above does not include the agglomerating element 82, and the water separating portion 203 is composed of the barrier portion 36D and the resin housing 202 as the housing on the water storage portion side. Is different from.
　具体的には、ハウジング２０２は、ハウジング８０と同様に樹脂製とされると共に、流出筒部２０４及び区画部２０６を含んで構成されている。流出筒部２０４は、第３方向から見て矩形状とされると共に軸方向を第３方向とされた筒状とされており、その上端部２０４Ａが蓋部３８に接合されている。また、流出筒部２０４には、複数の貫通部２０８が形成されており、流出筒部２０４の外側と内側とが貫通部２０８を介して連通された状態となっている。なお、本実施形態では、開口部７６が第１実施形態に比し拡大されている。 Specifically, the housing 202 is made of resin like the housing 80, and includes the outflow cylinder portion 204 and the compartment portion 206. The outflow tube portion 204 has a rectangular shape when viewed from the third direction and a tubular shape whose axial direction is the third direction, and the upper end portion 204A thereof is joined to the lid portion 38. Further, a plurality of penetrating portions 208 are formed in the outflow cylinder portion 204, and the outside and the inside of the outflow cylinder portion 204 are communicated with each other via the penetrating portion 208. In this embodiment, the opening 76 is enlarged as compared with the first embodiment.
　一方、区画部２０６は、区画部９０と同様に、その外形が第３方向下側に開放された箱状とされると共に、上壁部２０６Ａ、周壁部２０６Ｂ、仕切壁部２０６Ｃ及び一対の仕切壁部２０６Ｄを含んで構成されている。しかしながら、区画部２０６は、上壁部２０６Ａに形成された複数の貫通部２１０の形状が区画部９０と異なっている。 On the other hand, the partition portion 206 has a box shape whose outer shape is open downward in the third direction, like the partition portion 90, and the upper wall portion 206A, the peripheral wall portion 206B, the partition wall portion 206C, and a pair of partitions. It is configured to include the wall portion 206D. However, in the compartment 206, the shape of the plurality of penetrations 210 formed in the upper wall 206A is different from that of the compartment 90.
　詳しくは、貫通部２１０は、第３方向から見て上壁部２０６Ａにおけるハウジング本体部３６の障壁部３６Ｄ、周壁部２０６Ｂ、仕切壁部２０６Ｃ及び一対の仕切壁部２０６Ｄで囲まれる部分がそれぞれ刳り貫かれて形成されている。 Specifically, the penetrating portion 210 has a portion surrounded by the barrier portion 36D, the peripheral wall portion 206B, the partition wall portion 206C, and the pair of partition wall portions 206D of the housing main body portion 36 in the upper wall portion 206A when viewed from the third direction. It is formed through it.
　このような構成によれば、流出筒部２０４に流入した燃料から燃料よりも比重の大きい水分がその自重によって分離されて区画部２０６内に流下する。このため、本実施形態においても、基本的に上述した第１実施形態と同様の作用並びに効果を奏する。 According to such a configuration, water having a specific gravity larger than that of the fuel is separated from the fuel flowing into the outflow cylinder portion 204 by its own weight and flows down into the compartment portion 206. Therefore, this embodiment also has basically the same actions and effects as those of the first embodiment described above.
　また、本実施形態では、凝集エレメント８２を使用していないため、第１実施形態に比し、部品点数の低減を図ることができる。 Further, since the cohesive element 82 is not used in this embodiment, the number of parts can be reduced as compared with the first embodiment.
　＜第１１実施形態＞
　以下、図２７を用いて、開示される燃料フィルタの第１１実施形態について説明する。なお、上述した第１実施形態と同一構成部分については同一番号を付してその説明を省略する。 <11th Embodiment>
Hereinafter, the eleventh embodiment of the disclosed fuel filter will be described with reference to FIG. 27. The same components as those in the above-described first embodiment are designated by the same numbers, and the description thereof will be omitted.
　本実施形態に係る燃料フィルタ２２０は、基本的に第１実施形態に係る燃料フィルタ１０と同様の構成とされている。しかしながら、本実施形態では、貯留部側ハウジングとしてのハウジング２２２の構成が、ハウジング８０の構成と一部異なっている。 The fuel filter 220 according to the present embodiment has basically the same configuration as the fuel filter 10 according to the first embodiment. However, in the present embodiment, the configuration of the housing 222 as the housing on the storage portion side is partially different from the configuration of the housing 80.
　具体的には、本実施形態では、ハウジング２２２が、ハウジング８０と同様に継手部８４、上板部８６及び流出筒部８８を備えているものの、区画部２２４の構成がハウジング８０と異なっている。 Specifically, in the present embodiment, the housing 222 includes the joint portion 84, the upper plate portion 86, and the outflow cylinder portion 88 as in the housing 80, but the configuration of the partition portion 224 is different from that of the housing 80. ..
　区画部２２４は、中央部２２４Ａ、縦板部２２４Ｂ及び延出壁部２２４Ｃを含んで構成されている。中央部２２４Ａは、板厚方向を第３方向とされると共に第３方向から見て内周板部８６Ａと重なる板状とされており、流出筒部８８を第３方向下側から塞いでいる。縦板部２２４Ｂは、中央部２２４Ａの周縁部から第３方向下側に延びる筒状とされており、その外周面には、複数の突起部２２４Ｄが形成されている。 The partition portion 224 includes a central portion 224A, a vertical plate portion 224B, and an extension wall portion 224C. The central portion 224A has a plate-like shape in which the plate thickness direction is the third direction and overlaps with the inner peripheral plate portion 86A when viewed from the third direction, and the outflow cylinder portion 88 is closed from the lower side in the third direction. .. The vertical plate portion 224B has a tubular shape extending downward in the third direction from the peripheral edge portion of the central portion 224A, and a plurality of protrusions 224D are formed on the outer peripheral surface thereof.
　そして、延出壁部２２４Ｃは、縦板部２２４Ｂの第３方向下側の周縁部から中央部２２４Ａの反対側に延びる矩形の板状とされていると共に、貫通部９８と同様に貫通部２２６が形成されている。 The extending wall portion 224C has a rectangular plate shape extending from the lower peripheral edge portion of the vertical plate portion 224B in the third direction to the opposite side of the central portion 224A, and the penetrating portion 226 is similar to the penetrating portion 98. Is formed.
　このような構成によれば、凝集エレメント８２の外周面８２Ｂを流下した水が、ハウジング２２２の貫通部２２６を通って水貯留部４４の第３方向下側に溜まるようになっている。また、中央部２２４Ａ、縦板部２２４Ｂ及び延出壁部２２４Ｃによって水貯留部４４における第３方向中央部が仕切られるため、本実施形態においても、水貯留部４４内の水位が局部的に上昇することを抑制することができる。したがって、本実施形態においても基本的に上述した第１実施形態と同様の作用並びに効果を奏する。 According to such a configuration, the water flowing down the outer peripheral surface 82B of the cohesive element 82 passes through the penetrating portion 226 of the housing 222 and collects on the lower side in the third direction of the water storage portion 44. Further, since the central portion of the water storage portion 44 in the third direction is partitioned by the central portion 224A, the vertical plate portion 224B, and the extension wall portion 224C, the water level in the water storage portion 44 also rises locally in the present embodiment. It can be suppressed. Therefore, this embodiment also has basically the same functions and effects as those of the first embodiment described above.
　さらに、本実施形態では、ハウジング２２２に仕切壁部等の代わりに縦板部２２４Ｂが設けられているため、第１実施形態よりもハウジング２２２の構成を簡略化しつつ、凝集エレメント８２の大型化を図ることができる。 Further, in the present embodiment, since the housing 222 is provided with the vertical plate portion 224B instead of the partition wall portion and the like, the size of the cohesive element 82 can be increased while simplifying the configuration of the housing 222 as compared with the first embodiment. Can be planned.
　＜第１２実施形態＞
　以下、図２８を用いて、開示される燃料フィルタの第１２実施形態について説明する。なお、上述した第１実施形態と同一構成部分については同一番号を付してその説明を省略する。 <12th Embodiment>
Hereinafter, the twelfth embodiment of the disclosed fuel filter will be described with reference to FIG. 28. The same components as those in the above-described first embodiment are designated by the same numbers, and the description thereof will be omitted.
　本実施形態に係る燃料フィルタ２３０は、基本的に第１実施形態に係る燃料フィルタ１０と同様の構成とされている。しかしながら、本実施形態では、蓋部３８とハウジング本体部３６との組み付けに締結部材が用いられている点並びにハウジング８０がハウジング本体部３６と密着されている点が上述した第１実施形態と異なっている。 The fuel filter 230 according to the present embodiment has basically the same configuration as the fuel filter 10 according to the first embodiment. However, this embodiment differs from the first embodiment described above in that a fastening member is used for assembling the lid 38 and the housing body 36 and that the housing 80 is in close contact with the housing body 36. ing.
　具体的には、本実施形態では、ハウジング本体部３６の周縁部の複数箇所に雌ねじ部２３２が設けられており、蓋部３８の周縁部の複数箇所に雌ねじ部２３２に対応する貫通部２３４が形成されている。 Specifically, in the present embodiment, the female threaded portions 232 are provided at a plurality of locations on the peripheral edge of the housing main body 36, and the penetrating portions 234 corresponding to the female threaded portions 232 are provided at a plurality of locations on the peripheral edge of the lid 38. It is formed.
　そして、ボルト２３６が、第３方向上側から貫通部２３４に挿通されて雌ねじ部２３２に締結されることで蓋部３８がハウジング本体部３６に取り付けられている。なお、第１実施形態において、ハウジング本体部３６と蓋部３８との接合箇所とされていた部分には、シール部材２３８が配置されている。 Then, the lid portion 38 is attached to the housing main body portion 36 by inserting the bolt 236 into the penetrating portion 234 from the upper side in the third direction and fastening it to the female screw portion 232. In the first embodiment, the seal member 238 is arranged at a portion that is a joint portion between the housing main body portion 36 and the lid portion 38.
　一方、ハウジング本体部３６の底壁部３６Ｅには、その周縁部に沿って溝部２４０が形成されている。この溝部２４０は、その延在方向から見た断面形状が第３方向上側から第３方向下側に向かうに従って縮幅された三角形状とされている。また、ハウジング８０の周壁部９０Ｂの下端部には、溝部２４０に係合可能な突起部２４２が形成されている。 On the other hand, the bottom wall portion 36E of the housing main body portion 36 is formed with a groove portion 240 along the peripheral edge portion thereof. The groove 240 has a triangular shape in which the cross-sectional shape seen from the extending direction is narrowed from the upper side in the third direction to the lower side in the third direction. Further, a protrusion 242 that can be engaged with the groove 240 is formed at the lower end of the peripheral wall portion 90B of the housing 80.
　このような構成によれば、基本的に上述した第１実施形態と同様の作用並びに効果を奏する。また、本実施形態では、ボルト２３６の軸力によってハウジング８０の突起部２４２がハウジング本体部３６の溝部２４０に圧着されて、ハウジング８０の内側に溜まった水がハウジング８０の外側に流出することを抑制することができる。 According to such a configuration, basically the same actions and effects as those of the first embodiment described above are obtained. Further, in the present embodiment, the protrusion 242 of the housing 80 is crimped to the groove 240 of the housing body 36 by the axial force of the bolt 236, and the water accumulated inside the housing 80 flows out to the outside of the housing 80. It can be suppressed.
　＜第１３実施形態＞
　以下、図２９及び図３０を用いて、開示される燃料フィルタの第１３実施形態について説明する。なお、上述した第１実施形態と同一構成部分については同一番号を付してその説明を省略する。 <13th Embodiment>
Hereinafter, the thirteenth embodiment of the disclosed fuel filter will be described with reference to FIGS. 29 and 30. The same components as those in the above-described first embodiment are designated by the same numbers, and the description thereof will be omitted.
　本実施形態に係る燃料フィルタ２５０は、基本的に第１実施形態に係る燃料フィルタ１０と同様の構成とされている。しかしながら、本実施形態では、水貯留部４４と異物除去室部４６とが隔離されている点並びに水捕集器２５２が撥水部材２５４を備えている点が上述した第１実施形態と異なっている。 The fuel filter 250 according to the present embodiment has basically the same configuration as the fuel filter 10 according to the first embodiment. However, this embodiment is different from the above-described first embodiment in that the water storage portion 44 and the foreign matter removing chamber portion 46 are separated from each other and the water collector 252 is provided with the water repellent member 254. There is.
　具体的には、本実施形態では、外側ハウジング２５６のハウジング本体部２５８において、水貯留部４４と異物除去室部４６との境界部に設けられた障壁部２５８Ａの上端部に継手部３６Ａと同様の構成とされた継手部２５８Ａ１が設けられている。 Specifically, in the present embodiment, in the housing main body portion 258 of the outer housing 256, the upper end portion of the barrier portion 258A provided at the boundary portion between the water storage portion 44 and the foreign matter removing chamber portion 46 is the same as the joint portion 36A. A joint portion 258A1 having the above configuration is provided.
　一方、外側ハウジング２５６の蓋部２６０におけるハウジング本体部２５８側の面には、第３方向から見て継手部２５８Ａ１と重なる位置に継手部３８Ｂと同様の構成とされた継手部２６０Ａが設けられている。そして、本実施形態では、継手部２５８Ａ１と継手部２６０Ａとが振動溶着によって接合されることで、水貯留部４４と異物除去室部４６とが隔離された状態となっている。 On the other hand, on the surface of the lid portion 260 of the outer housing 256 on the housing body portion 258 side, a joint portion 260A having the same configuration as the joint portion 38B is provided at a position overlapping the joint portion 258A1 when viewed from the third direction. There is. In the present embodiment, the joint portion 258A1 and the joint portion 260A are joined by vibration welding, so that the water storage portion 44 and the foreign matter removing chamber portion 46 are separated from each other.
　また、蓋部２６０は、天板部２６０Ｂ及び上側流路部２６０Ｃを含んで、基本的に蓋部３８と同様の構成とされているものの、一部が蓋部３８と異なっている。 Further, the lid portion 260 includes the top plate portion 260B and the upper flow path portion 260C, and has basically the same configuration as the lid portion 38, but a part thereof is different from the lid portion 38.
　詳しくは、本実施形態では、上側流路部２６０Ｃは、水貯留部４４の第１方向一方側において、水貯留部４４と連通されている。また、天板部２６０Ｂの第３方向上側の部分には、連結流路部２６０Ｄが設けられている。この連結流路部２６０Ｄは、開口部７６から障壁部２５８Ａの第３方向上側を経由して第１方向他方側に延びており、水貯留部４４と異物除去室部４６とを連通させている。 Specifically, in the present embodiment, the upper flow path portion 260C is communicated with the water storage portion 44 on one side in the first direction of the water storage portion 44. Further, a connecting flow path portion 260D is provided on the upper portion of the top plate portion 260B in the third direction. The connecting flow path portion 260D extends from the opening 76 to the other side in the first direction via the upper side in the third direction of the barrier portion 258A, and communicates the water storage portion 44 and the foreign matter removing chamber portion 46. ..
　次に、水捕集器２５２の構成について説明する。水捕集器２５２は、上述したように撥水部材２５４と、水貯留部側ハウジングとしての樹脂製のハウジング２６２とを含んで構成されている。ハウジング２６２は、基本的にハウジング８０と同様の構成とされているものの、上板部２６４には、外周板部８６Ｃに代わって係止部２６４Ａが設けられている。 Next, the configuration of the water collector 252 will be described. As described above, the water collector 252 includes a water repellent member 254 and a resin housing 262 as a housing on the water storage portion side. Although the housing 262 has basically the same structure as the housing 80, the upper plate portion 264 is provided with a locking portion 264A in place of the outer peripheral plate portion 86C.
　一方、撥水部材２５４は、親油性及び撥水性を備えた材質（例えば、ポリプロピレン等）で構成されていると共に、シート状とされている。そして、撥水部材２５４は、上板部２６４の内周板部２６４Ｂと区画部９０の上壁部９０Ａの中央部９０Ａ１とに架け渡された状態で、流出筒部８８の周方向に沿うようにハウジング２６２に張り付けられている。なお、撥水部材２５４の第３方向上側の周縁部は、係止部２６４Ａに係止されている。 On the other hand, the water-repellent member 254 is made of a material having lipophilicity and water repellency (for example, polypropylene, etc.) and has a sheet shape. Then, the water-repellent member 254 is bridged between the inner peripheral plate portion 264B of the upper plate portion 264 and the central portion 90A1 of the upper wall portion 90A of the partition portion 90 so as to follow the circumferential direction of the outflow cylinder portion 88. Is attached to the housing 262. The upper peripheral edge of the water repellent member 254 in the third direction is locked to the locking portion 264A.
　このような構成によれば、燃料が撥水部材２５４を通過するときに、燃料から水分が分離されて、水分が区画部９０内に流下する。一方、水分が除去された燃料は、連結流路部２６０Ｄを通って、異物除去室部４６内に流入する。このため、本実施形態においても、基本的に上述した第１実施形態と同様の作用並びに効果を奏する。 According to such a configuration, when the fuel passes through the water-repellent member 254, the water is separated from the fuel and the water flows down into the compartment 90. On the other hand, the fuel from which the water has been removed flows into the foreign matter removing chamber 46 through the connecting flow path portion 260D. Therefore, this embodiment also has basically the same actions and effects as those of the first embodiment described above.
　また、本実施形態では、障壁部２５８Ａによって水貯留部４４と異物除去室部４６とが隔離されているため、燃料から分離された水が燃料に再度混入することを抑制することができる。 Further, in the present embodiment, since the water storage portion 44 and the foreign matter removal chamber portion 46 are separated by the barrier portion 258A, it is possible to prevent the water separated from the fuel from being mixed into the fuel again.

　次に、図４４及び図４７を主に用いて、異物除去室部２０４６の内側に配置された異物捕集器２１０２の構成について説明することとする。異物捕集器２１０２は、異物除去部側ハウジングとしての樹脂製のハウジング２１０４と、異物除去エレメント２１０６とを含んで構成されている。 Next, the configuration of the foreign matter collector 2102 arranged inside the foreign matter removing chamber 2046 will be described mainly using FIGS. 44 and 47. The foreign matter collector 2102 is configured to include a resin housing 2104 as a foreign matter removing portion side housing and a foreign matter removing element 2106.
　ハウジング２１０４は、底壁部２１０８、接続部２１１０及び周壁部２１１１を含んで構成されており、全体的には第３方向上側が開放された箱状とされている。詳しくは、底壁部２１０８は、ハウジング２１０４の第３方向下側の部分を構成すると共に、第３方向から見て第１方向及び第２方向に延在する矩形の板状とされている。また、底壁部２１０８の上面部２１０８Ａには、上面部２１０８Ａから第３方向上側に突出したスペーサ部としての複数の突起部２１０８Ｂが設けられている。 The housing 2104 includes a bottom wall portion 2108, a connecting portion 2110, and a peripheral wall portion 2111, and has a box shape in which the upper side in the third direction is open as a whole. Specifically, the bottom wall portion 2108 constitutes a lower portion of the housing 2104 in the third direction and has a rectangular plate shape extending in the first direction and the second direction when viewed from the third direction. Further, the upper surface portion 2108A of the bottom wall portion 2108 is provided with a plurality of protrusions 2108B as spacer portions protruding upward in the third direction from the upper surface portion 2108A.
　接続部２１１０は、軸方向を第３方向とされた円筒状とされていると共に、底壁部２１０８の中央部から第３方向下側に延出されている。この接続部２１１０の外周面には、接続部２１１０の周方向に延びる溝部２１１２が形成されており、溝部２１１２には、シール部材２１１４が嵌め込まれている。 The connecting portion 2110 has a cylindrical shape with the axial direction as the third direction, and extends downward from the central portion of the bottom wall portion 2108 in the third direction. A groove portion 2112 extending in the circumferential direction of the connection portion 2110 is formed on the outer peripheral surface of the connection portion 2110, and a seal member 2114 is fitted in the groove portion 2112.
　そして、ハウジング２１０４は、接続部２１１０が第３方向上側から流出口部２０４８の液溜め部２０４８Ａに嵌合されることで、ハウジング本体部２０３６に対して固定されている。そして、ハウジング２１０４は、第３方向下側において燃料配管２４側に連通された状態となっている。なお、ハウジング２１０４がハウジング本体部２０３６に取り付けられた状態において、底壁部２１０８の下面部２１０８Ｃとハウジング本体部２０３６の底壁部２０３６Ｃとの間には、底壁部２０３６Ｃに設けられた突起部２１１５によって隙間が確保された状態となっている。すなわち、下面部２１０８Ｃと底壁部２０３６Ｃとの間には、突起部２１１５によって燃料が流れる流路が形成されていると見なすことができる。また、突起部２１１５は、底壁部２０３６Ｃの補強部としても機能している。 Then, the housing 2104 is fixed to the housing main body portion 2036 by fitting the connecting portion 2110 to the liquid reservoir portion 2048A of the outlet portion 2048 from the upper side in the third direction. The housing 2104 is in a state of communicating with the fuel pipe 24 side on the lower side in the third direction. In the state where the housing 2104 is attached to the housing main body 2036, a protrusion provided on the bottom wall 2036C is provided between the lower surface 2108C of the bottom wall 2108 and the bottom wall 2036C of the housing main body 2036. A gap is secured by 2115. That is, it can be considered that a flow path through which fuel flows is formed by the protrusion 2115 between the lower surface portion 2108C and the bottom wall portion 2036C. The protrusion 2115 also functions as a reinforcing portion of the bottom wall portion 2036C.
　周壁部２１１１は、底壁部２１０８の周縁部から第３方向上側に延びる角筒状とされていると共に、その上端部は、蓋部２０３８の天板部２０３８Ａに対して所定の間隔があけられた位置に位置している。 The peripheral wall portion 2111 has a square tubular shape extending upward in the third direction from the peripheral edge portion of the bottom wall portion 2108, and the upper end portion thereof is spaced apart from the top plate portion 2038A of the lid portion 2038. It is located in the same position.
　一方、異物除去エレメント２１０６は、例えば、濾紙やポリエステル系不織布等で構成されると共に、複数のプリーツ部２１０６Ａを備えたプリーツ型とされており、燃料が通過することで、燃料に含まれた埃等の異物を除去可能とされている。なお、異物除去エレメント２１０６は、所定量の水分を燃料から除去することも可能とされている。 On the other hand, the foreign matter removing element 2106 is made of, for example, filter paper, polyester-based non-woven fabric, or the like, and is a pleated type having a plurality of pleated portions 2106A. When the fuel passes through, the dust contained in the fuel is contained. It is possible to remove foreign substances such as. The foreign matter removing element 2106 is also capable of removing a predetermined amount of water from the fuel.
　この異物除去エレメント２１０６は、その外形が直方体状とされており、ハウジング２１０４の内側に収容されると共に、ハウジング２１０４の突起部２１０８Ｂに図示しない接着剤等による接合部によって接合されている。つまり、ハウジング２１０４の底壁部２１０８と異物除去エレメント２１０６とは、点接触した状態となっており、底壁部２１０８と異物除去エレメント２１０６との間には、燃料が流入可能な隙間が確保された状態となっている。 The foreign matter removing element 2106 has a rectangular parallelepiped outer shape, is housed inside the housing 2104, and is joined to the protrusion 2108B of the housing 2104 by a joint portion such as an adhesive (not shown). That is, the bottom wall portion 2108 of the housing 2104 and the foreign matter removing element 2106 are in a point contact state, and a gap through which fuel can flow is secured between the bottom wall portion 2108 and the foreign matter removing element 2106. It is in a state of being.
　また、異物除去エレメント２１０６は、燃料が隙間２０６８を通って異物除去室部２０４６に流れ込む方向（第１方向）に対して直交する方向（第２方向）にプリーツ部２１０６Ａの山と谷とが繰り返されるように配置されるのが好ましい。これにより、異物除去室部２０４６内の限られた空間（扁平の直方体状の空間）の中において、異物除去エレメント２１０６の有効面積を最も大きく確保しつつ、燃料が異物除去エレメント２１０６における流出口部２０４８側（側壁部２０３６Ｇ側）の端部に到達することが容易となる。 Further, in the foreign matter removing element 2106, the peaks and valleys of the pleated portion 2106A are repeated in the direction (second direction) orthogonal to the direction (first direction) in which the fuel flows into the foreign matter removing chamber portion 2046 through the gap 2068. It is preferable that they are arranged so as to be. As a result, in the limited space (flat rectangular parallelepiped space) in the foreign matter removing chamber portion 2046, the fuel is discharged from the foreign matter removing element 2106 while ensuring the largest effective area of the foreign matter removing element 2106. It becomes easy to reach the end portion on the 2048 side (side wall portion 2036G side).
　上記のように構成された異物捕集器２１０２では、水貯留部２０４４側から隙間２０６８通って異物除去室部２０４６側に流入した燃料が、異物除去エレメント２１０６をその第３方向上側から第３方向下側に向かって通り抜けるようになっている。そして、異物除去エレメント２１０６を通り抜けた燃料は、埃等の異物が除去された状態で、流出口部２０４８を経て燃料配管２４に流出されるようになっている。 In the foreign matter collector 2102 configured as described above, the fuel flowing from the water storage portion 2044 side through the gap 2068 to the foreign matter removing chamber portion 2046 side moves the foreign matter removing element 2106 from the upper side in the third direction to the third direction. It is designed to pass through toward the bottom. Then, the fuel that has passed through the foreign matter removing element 2106 flows out to the fuel pipe 24 through the outlet portion 2048 in a state where foreign matter such as dust is removed.

　次に、本実施形態の作用及び効果を説明する。 (Action and effect of this embodiment)
Next, the operation and effect of this embodiment will be described.
　本実施形態では、図４４に示されるように、流入口部２０３８Ｃ側から水貯留部２０４４に流入された燃料から分離された水分が、水貯留部２０４４に貯留される。また、異物除去部２０３４では、水貯留部２０４４側から流入された燃料から異物が除去される。そして、燃料は、異物除去部２０３４側から流出口部２０４８に流れて、流出口部２０４８から流出される。 In the present embodiment, as shown in FIG. 44, the water separated from the fuel that has flowed into the water storage section 2044 from the inflow port section 2038C side is stored in the water storage section 2044. Further, the foreign matter removing unit 2034 removes foreign matter from the fuel flowing in from the water storage unit 2044 side. Then, the fuel flows from the foreign matter removing portion 2034 side to the outlet portion 2048, and flows out from the outlet portion 2048.
　ところで、燃料フィルタにおいて、水貯留部２０４４の機能と異物除去部２０３４の機能とを一箇所に集約することが考えられる。例えば、燃料フィルタに室部を設けると共に、当該室部の第３方向上側に異物除去部２０３４を配置し、燃料と水との比重の違いを利用して当該室部の第３方向下側に水を貯留するような構成が考えられる。 By the way, in the fuel filter, it is conceivable to consolidate the functions of the water storage section 2044 and the functions of the foreign matter removing section 2034 into one place. For example, the fuel filter is provided with a chamber, and the foreign matter removing portion 2034 is arranged on the upper side of the chamber in the third direction, and the difference in specific gravity between fuel and water is utilized to be on the lower side of the chamber in the third direction. A configuration that stores water is conceivable.
　しかしながら、このような構成を採用すると、室部に貯留された水と燃料との混合を避けるため、当該室部の第３方向上側に流入口部２０３８Ｃ及び流出口部２０４８を配置することが必要となる。また、燃料から分離された水分が再び燃料に混入するのを避けるため、燃料を異物除去部２０３４の第３方向上側から異物除去部２０３４の第３方向下側に通すと共に異物除去部２０３４を経由した燃料を流出口部２０４８に導く流路が必要となる。そして、このような構成では、燃料フィルタ内に燃料を回流させる必要があり、当該燃料の通る流路が複雑になる。 However, when such a configuration is adopted, it is necessary to arrange the inflow port portion 2048C and the outflow port portion 2048 on the upper side in the third direction of the chamber part in order to avoid mixing the water stored in the chamber part with the fuel. It becomes. Further, in order to prevent the water separated from the fuel from being mixed into the fuel again, the fuel is passed from the upper side of the foreign matter removing unit 2034 in the third direction to the lower side of the foreign matter removing unit 2034 in the third direction and also passes through the foreign matter removing unit 2034. A flow path is required to guide the fuel to the outlet 2048. In such a configuration, it is necessary to circulate the fuel in the fuel filter, and the flow path through which the fuel passes becomes complicated.
　ここで、本実施形態では、異物除去部２０３４が第３方向から見て水貯留部２０４４と重ならないように配置されていると共に、異物除去部２０３４の第３方向下側に流出口部２０４８が配置されている。このため、本実施形態では、燃料が流入口部２０３８Ｃから流出口部２０４８に向かって流れる過程において、当該燃料が流れる向きが変化することを抑制することができる。その結果、本実施形態では、燃料から水分及び異物の除去を可能としつつ、燃料が通る流路を単純にすることができる。 Here, in the present embodiment, the foreign matter removing portion 2034 is arranged so as not to overlap the water storage portion 2048 when viewed from the third direction, and the outlet portion 2048 is located below the foreign matter removing portion 2034 in the third direction. Have been placed. Therefore, in the present embodiment, it is possible to suppress the change in the direction in which the fuel flows in the process of the fuel flowing from the inflow port portion 2048C toward the outflow port portion 2048. As a result, in the present embodiment, the flow path through which the fuel passes can be simplified while enabling the removal of water and foreign matter from the fuel.
　また、本実施形態では、流入口部２０３８Ｃが水貯留部２０４４の第３方向上側に設けられており、燃料は、燃料フィルタ２０１０の内部を第３方向上側から第３方向下側に向かって流れる。このため、本実施形態では、燃料フィルタ２０１０の内側において、燃料の流れを円滑なものとすることができ、その結果、燃料が燃料フィルタ２０１０の内側を流れるときに受ける抵抗を低減することができる。 Further, in the present embodiment, the inflow port portion 2038C is provided on the upper side of the water storage portion 2044 in the third direction, and the fuel flows inside the fuel filter 2010 from the upper side in the third direction to the lower side in the third direction. .. Therefore, in the present embodiment, the flow of fuel can be made smooth inside the fuel filter 2010, and as a result, the resistance received when the fuel flows inside the fuel filter 2010 can be reduced. ..
　また、本実施形態では、水貯留部２０４４及び異物除去部２０３４が外側ハウジング２０２８のハウジング本体部２０３６に一体に設けられていると共に、水貯留部２０４４と異物除去部２０３４との境界部には、障壁部２０３６Ｂが設けられている。このため、水貯留部２０４４と異物除去部２０３４とが別体とされているような構成に比し、燃料フィルタ２０１０の取付作業を簡略化することができる。さらに、水貯留部２０４４に貯留された水の異物除去部２０３４側への侵入が規制され、その結果、燃料から分離された水が再度燃料に混入することを抑制することができる。 Further, in the present embodiment, the water storage portion 2044 and the foreign matter removing portion 2034 are integrally provided with the housing main body portion 2036 of the outer housing 2028, and the boundary portion between the water storage portion 2044 and the foreign matter removing portion 2034 is provided at the boundary portion. A barrier portion 2036B is provided. Therefore, the installation work of the fuel filter 2010 can be simplified as compared with the configuration in which the water storage unit 2044 and the foreign matter removing unit 2034 are separated. Further, the invasion of the water stored in the water storage unit 2044 to the foreign matter removing unit 2034 side is restricted, and as a result, the water separated from the fuel can be prevented from being mixed into the fuel again.
　また、本実施形態では、ハウジング２１０４に突起部２１０８Ｂが設けられており、異物除去エレメント２１０６の第３方向下側に隙間が確保された状態となっている。このため、異物除去エレメント２１０６の全体において、異物除去エレメント２１０６の下方側に燃料が進入しやすくなり、燃料が異物除去エレメント２１０６の一部のみを通過することを抑制することができる。その結果、本実施形態では、異物除去エレメント２１０６に局部的に燃料から除去された異物が溜まることを抑制することができる。 Further, in the present embodiment, the housing 2104 is provided with the protrusion 2108B, and a gap is secured on the lower side of the foreign matter removing element 2106 in the third direction. Therefore, in the entire foreign matter removing element 2106, the fuel easily enters the lower side of the foreign matter removing element 2106, and it is possible to prevent the fuel from passing through only a part of the foreign matter removing element 2106. As a result, in the present embodiment, it is possible to prevent the foreign matter removed from the fuel from being locally accumulated in the foreign matter removing element 2106.
　また、本実施形態では、ハウジング２１０４の内側に異物除去エレメント２１０６が取り付けられてサブアッセンブリ、すなわち異物捕集器２１０２が構成されている。このため、異物除去エレメント２１０６を直接ハウジング本体部２０３６に取り付けるような構成に比し、燃料フィルタ２０１０の組立作業を簡略化することができる。 Further, in the present embodiment, the foreign matter removing element 2106 is attached to the inside of the housing 2104 to form a sub-assembly, that is, a foreign matter collector 2102. Therefore, the assembly work of the fuel filter 2010 can be simplified as compared with the configuration in which the foreign matter removing element 2106 is directly attached to the housing main body 2036.
　加えて、本実施形態では、水貯留部２０４４の第３方向の寸法Ｉ１が、水貯留部２０４４を第３方向から見た投影面上の最も離れた２点間の距離よりも短い長さに設定されており、水貯留部２０４４（水分離部２０３２）の寸法Ｉ１が長くなることを抑制することができる。また、異物除去部２０３４の第３方向の寸法Ｉ２が、異物除去部２０３４を第３方向から見た投影面上の２点間の距離よりも短い長さに設定されており、寸法Ｉ２が長くなることを抑制することができる。 In addition, in the present embodiment, the dimension I1 of the water storage unit 2044 in the third direction is shorter than the distance between the two farthest points on the projection plane when the water storage unit 2044 is viewed from the third direction. It is set, and it is possible to prevent the dimension I1 of the water storage unit 2044 (water separation unit 2032) from becoming long. Further, the dimension I2 of the foreign matter removing portion 2034 in the third direction is set to be shorter than the distance between two points on the projection surface when the foreign matter removing portion 2034 is viewed from the third direction, and the dimension I2 is long. It can be suppressed.
　しかも、本実施形態では、異物除去部２０３４が第３方向から見て水貯留部２０４４と重ならないように配置されている。このため、異物除去部２０３４と水貯留部２０４４とが第３方向に連なって配置されているような構成に比し、搭載の自由度をより向上させることができる。 Moreover, in the present embodiment, the foreign matter removing portion 2034 is arranged so as not to overlap with the water storage portion 2044 when viewed from the third direction. Therefore, the degree of freedom of mounting can be further improved as compared with the configuration in which the foreign matter removing unit 2034 and the water storage unit 2044 are arranged in a row in the third direction.

　以下、図４９を用いて、開示される燃料フィルタの第２５実施形態について説明する。なお、上述した第２４実施形態と同一構成部分については同一番号を付してその説明を省略する。 <25th Embodiment>
Hereinafter, the 25th embodiment of the disclosed fuel filter will be described with reference to FIG. 49. The same components as those in the above-described 24th embodiment are designated by the same numbers, and the description thereof will be omitted.
　本実施形態に係る燃料フィルタ２１２０は、基本的に第２４実施形態に係る燃料フィルタ２０１０と同様の構成とされている。しかしながら、本実施形態では、外側ハウジング２１２２の蓋部２１２４に流入口部が設けられておらず、外側ハウジング２１２２のハウジング本体部２１２６に流入口部２１２８が設けられている点が上述した第２４実施形態と異なっている。また、水捕集器２１３０の樹脂製のハウジング２１３２の構成が、ハウジング２０８０の構成と異なっている。 The fuel filter 2120 according to the present embodiment has basically the same configuration as the fuel filter 2010 according to the 24th embodiment. However, in the 24th embodiment described above, in the present embodiment, the inflow port portion is not provided in the lid portion 2124 of the outer housing 2122, and the inflow port portion 2128 is provided in the housing main body portion 2126 of the outer housing 2122. It is different from the form. Further, the configuration of the resin housing 2132 of the water collector 2130 is different from the configuration of the housing 2080.
　具体的には、流入口部２１２８は、流入口部２０３８Ｃと同様の構成とされると共に、ハウジング本体部２１２６における底壁部２１２６Ａの第３方向下側に配置されており、その第１方向他方側の端部２１２８Ａにおける第３方向上側において底壁部２１２６Ａに設けられた開口部２１３４と連通されている。なお、ハウジング本体部２１２６の流出口部２１３６は、流出口部２０４８と同様の構成とされている。 Specifically, the inflow port portion 2128 has the same configuration as the inflow port portion 2038C, and is arranged on the lower side of the bottom wall portion 2126A in the housing main body portion 2126 in the third direction, and the other side in the first direction thereof. It communicates with the opening 2134 provided in the bottom wall 2126A on the upper side of the side end 2128A in the third direction. The outlet portion 2136 of the housing main body portion 2126 has the same configuration as the outlet portion 2048.
　一方、ハウジング本体部２１２６の内側には、ハウジング２１３２を支持する支持部２１３８が設けられている。この支持部２１３８は、第３方向から見て開口部２１３４を囲むオーバル形状（例えば、角丸長方形状）とされると共にハウジング本体部２１２６の底壁部２１２６Ａから第３方向上側に延びる筒状とされている。また、支持部２１３８には、複数の図示しない貫通部が形成されている。 On the other hand, a support portion 2138 for supporting the housing 2132 is provided inside the housing main body portion 2126. The support portion 2138 has an oval shape (for example, a rectangular shape with rounded corners) surrounding the opening 2134 when viewed from the third direction, and has a tubular shape extending upward from the bottom wall portion 2126A of the housing main body 2126 in the third direction. Has been done. Further, the support portion 2138 is formed with a plurality of penetration portions (not shown).
　ハウジング２１３２は、ハウジング２０８０と同様に上板部２１４０、流出筒部２１４２及び下板部２１４４を備えているものの、継手部の代わりに支持筒部２１４６が設けられている点がハウジング２０８０と異なっている。 The housing 2132 has an upper plate portion 2140, an outflow cylinder portion 2142, and a lower plate portion 2144 like the housing 2080, but differs from the housing 2080 in that a support cylinder portion 2146 is provided instead of the joint portion. There is.
　詳しくは、支持筒部２１４６は、流出筒部２１４２から第３方向下側に延びる筒状とされた本体部２１４６Ａ、本体部２１４６Ａの第３方向下側の端部に設けられた鍔部２１４６Ｂ及び突起部２１４６Ｃを含んで構成されている。鍔部２１４６Ｂは、本体部２１４６Ａの外周側に延びると共に第３方向から見て開口部２１３４よりも一回り大きい板状とされている。 Specifically, the support cylinder portion 2146 includes a main body portion 2146A having a tubular shape extending downward from the outflow cylinder portion 2142 in the third direction, a flange portion 2146B provided at the lower end portion of the main body portion 2146A in the third direction, and the like. It is configured to include the protrusion 2146C. The collar portion 2146B extends toward the outer peripheral side of the main body portion 2146A and has a plate shape that is one size larger than the opening 2134 when viewed from the third direction.
　そして、本体部２１４６Ａは、開口部２１３４に第３方向上側から挿入された状態とされると共に、鍔部２１４６Ｂによってハウジング本体部２１２６の底壁部２１２６Ａに支持された状態となっている。また、支持筒部２１４６が開口部２１３４に取り付けられている状態において、ハウジング２１３２の下板部２１４４は、支持部２１３８に支持されている。なお、凝集エレメント２０８２は、上板部２１４０と下板部２１４４との間に配置されている。 Then, the main body portion 2146A is in a state of being inserted into the opening 2134 from the upper side in the third direction, and is also in a state of being supported by the bottom wall portion 2126A of the housing main body portion 2126 by the flange portion 2146B. Further, in a state where the support cylinder portion 2146 is attached to the opening 2134, the lower plate portion 2144 of the housing 2132 is supported by the support portion 2138. The agglomeration element 2082 is arranged between the upper plate portion 2140 and the lower plate portion 2144.
　一方、突起部２１４６Ｃは、鍔部２１４６Ｂの第３方向下側に配置されており、第３方向から見て本体部２１４６Ａの外周に沿う環状とされている。この突起部２１４６Ｃには、本体部２１４６Ａの周方向に延びると共に本体部２１４６Ａの内周側に凹んだ溝部２１４８が設けられており、この溝部２１４８には、Ｏリング２１５０が嵌め込まれている。そして、Ｏリング２１５０は、支持筒部２１４６が開口部２１３４に取り付けられている状態において、開口部２１３４の内周面に密着された状態となっている。 On the other hand, the protrusion 2146C is arranged on the lower side of the flange 2146B in the third direction, and is formed to be an annular shape along the outer circumference of the main body 2146A when viewed from the third direction. The protrusion 2146C is provided with a groove 2148 that extends in the circumferential direction of the main body 2146A and is recessed on the inner peripheral side of the main body 2146A, and an O-ring 2150 is fitted in the groove 2148. The O-ring 2150 is in close contact with the inner peripheral surface of the opening 2134 in a state where the support cylinder 2146 is attached to the opening 2134.
　このような構成によれば、流入口部２１２８から支持筒部２１４６を経由して流出筒部２１４２から流出された燃料が、凝集エレメント２０８２を通過すると、凝集エレメント２０８２の外周面２０８２Ｂにおいて、燃料に含まれた微小な水滴が大きな水滴となって流下する。そして、凝集エレメント２０８２から流下した水滴は、支持部２１３８の内側も含む水貯留部２０４４の第３方向下側に溜まる。このため、本実施形態においても、基本的に上述した第２４実施形態と同様の作用並びに効果を奏する。 According to such a configuration, when the fuel flowing out from the inflow port portion 2128 via the support cylinder portion 2146 and the outflow cylinder portion 2142 passes through the aggregating element 2082, it becomes a fuel on the outer peripheral surface 2082B of the aggregating element 2082. The contained minute water droplets become large water droplets and flow down. Then, the water droplets flowing down from the agglomeration element 2082 collect on the lower side in the third direction of the water storage portion 2044 including the inside of the support portion 2138. Therefore, also in this embodiment, basically the same actions and effects as those in the above-described 24th embodiment are obtained.
　また、本実施形態では、流入口部２１２８及び流出口部２１３６が、ハウジング本体部２１２６に設けられており、流入口部が蓋部２１２４に設けられている構成に比し、燃料フィルタ２１２０が第３方向に拡大することを抑制することができる。 Further, in the present embodiment, the fuel filter 2120 is the first in comparison with the configuration in which the inflow port portion 2128 and the outflow port portion 2136 are provided in the housing main body portion 2126 and the inflow port portion is provided in the lid portion 2124. Expansion in three directions can be suppressed.
　＜第２６実施形態＞
　以下、図５０～図５２を用いて、開示される燃料フィルタの第２６実施形態について説明する。なお、上述した第２４実施形態と同一構成部分については同一番号を付してその説明を省略する。 <26th Embodiment>
Hereinafter, the 26th embodiment of the disclosed fuel filter will be described with reference to FIGS. 50 to 52. The same components as those in the above-described 24th embodiment are designated by the same numbers, and the description thereof will be omitted.
　本実施形態に係る燃料フィルタ２１６０は、基本的に第２４実施形態に係る燃料フィルタ２０１０と同様の構成とされている。しかしながら、本実施形態では、ハウジング本体部２０３６の障壁部２０３６Ｂに設けられた変流部２１６２が隙間２０６８に配置されている点が上述した第２４実施形態と異なっている。 The fuel filter 2160 according to the present embodiment has basically the same configuration as the fuel filter 2010 according to the 24th embodiment. However, this embodiment is different from the above-described 24th embodiment in that the diversion portion 2162 provided in the barrier portion 2036B of the housing main body portion 2036 is arranged in the gap 2068.
　具体的には、変流部２１６２は、本体部２１６２Ａと一対のガイド部２１６２Ｂとを含んで、鋼製の板材で構成されている。本体部２１６２Ａは、障壁部２０３６Ｂの上端部における第１方向一方側の面に沿う取付板部２１６２Ａ１と、取付板部２１６２Ａ１から第３方向上側でかつ第１方向他方側（斜め上方）に延びる延出板部２１６２Ａ２とを含んで構成されている。より詳しくは、延出板部２１６２Ａ２は、第１方向一方側の部分においては、第３方向上側でかつ第１方向他方側に向かって延びており、第１方向他方側の部分においては、第１方向他方側（水平方向）に向かって延びるように屈曲している。 Specifically, the current change portion 2162 includes a main body portion 2162A and a pair of guide portions 2162B, and is made of a steel plate material. The main body 2162A extends from the mounting plate 2162A1 along the surface on one side in the first direction at the upper end of the barrier 2036B and extending from the mounting plate 2162A1 on the upper side in the third direction and on the other side (obliquely upward) in the first direction. It is configured to include a plate portion 2162A2. More specifically, the extension plate portion 2162A2 extends on the upper side in the third direction and toward the other side in the first direction in the portion on one side in the first direction, and in the portion on the other side in the first direction, the first It is bent so as to extend in one direction and the other side (horizontal direction).
　なお、取付板部２１６２Ａ１は、接着剤やリベット等の図示しない接合部によって障壁部２０３６Ｂの上端部に接合されている。また、本体部２１６２Ａの第２方向一方側の端部は、側壁部２０３６Ｄに対して、本体部２１６２Ａの第２方向他方側の端部は、側壁部２０３６Ｅに対して、それぞれ第２方向において間隔があけられた状態となっている。 The mounting plate portion 2162A1 is joined to the upper end portion of the barrier portion 2036B by a joint portion (not shown) such as an adhesive or a rivet. Further, the end portion of the main body portion 2162A on one side in the second direction is spaced from the side wall portion 2036D, and the end portion of the main body portion 2162A on the other side in the second direction is spaced from the side wall portion 2036E in the second direction. Is in an open state.
　また、ガイド部２１６２Ｂは、延出板部２１６２Ａ２の第２方向一方側の周縁部及び第２方向他方側の周縁部のそれぞれに沿って設けられており、当該周縁部から第３方向上側に延出されると共に延出板部２１６２Ａ２の延在方向において幅が一定とされている。 Further, the guide portion 2162B is provided along each of the peripheral edge portion on one side in the second direction and the peripheral edge portion on the other side in the second direction of the extension plate portion 2162A2, and extends upward from the peripheral edge portion in the third direction. The width is fixed in the extending direction of the extending plate portion 2162A2 as well as being extended.
　上記のように構成された変流部２１６２は、燃料の流れる向きを異物除去エレメント２１０６における障壁部２０３６Ｂと反対側の部分に到達可能な向きに変更可能とされている。 The flow change portion 2162 configured as described above can change the direction in which the fuel flows so as to reach the portion of the foreign matter removing element 2106 opposite to the barrier portion 2036B.
　なお、本実施形態では、蓋部２０３８の天板部２０３８Ａにおいて、第３方向から見て障壁部２０３６Ｂ及び異物除去室部２０４６と重なる部分は、第３方向上側に膨出している。 In the present embodiment, in the top plate portion 2038A of the lid portion 2038, the portion overlapping the barrier portion 2036B and the foreign matter removing chamber portion 2046 when viewed from the third direction bulges upward in the third direction.
　このような構成によれば、基本的に上述した第２４実施形態と同様の作用並びに効果を奏する。また、本実施形態では、変流部２１６２によって、燃料の流れる向きが、異物除去エレメント２１０６における障壁部２０３６Ｂと反対側の部分に到達可能な向きに変更される。このため、異物除去エレメント２１０６の大部分で燃料から異物を除去することが可能となり、異物除去エレメント２１０６の局所的な目詰まりを抑制することができる。 According to such a configuration, basically the same actions and effects as those of the 24th embodiment described above are obtained. Further, in the present embodiment, the flow direction of the fuel is changed by the flow change portion 2162 so as to reach the portion of the foreign matter removing element 2106 opposite to the barrier portion 2036B. Therefore, most of the foreign matter removing element 2106 can remove foreign matter from the fuel, and local clogging of the foreign matter removing element 2106 can be suppressed.
　ところで、燃料が隙間２０６８を通るときに、ハウジング本体部２０３６の側壁部２０３６Ｄ、２０３６Ｅの近傍に比し、隙間２０６８の第２方向中央側では燃料に対する抵抗が小さくなるため、燃料の流速は、隙間２０６８の第２方向中央部から側壁部２０３６Ｄ、２０３６Ｅに向かうに従って小さくなる。 By the way, when the fuel passes through the gap 2068, the resistance to the fuel is smaller on the center side of the gap 2068 in the second direction than in the vicinity of the side wall portions 2036D and 2036E of the housing main body 2036, so that the flow velocity of the fuel is the gap. It becomes smaller toward the side wall portions 2036D and 2036E from the central portion in the second direction of 2068.
　ここで、本実施形態では、変流部２１６２が側壁部２０３６Ｄ、２０３６Ｅに対して間隔があけられた状態となっている。このため、側壁部２０３６Ｄ、２０３６Ｅの近傍を通る燃料を異物除去エレメント２１０６における障壁部２０３６Ｂ側に導くことができると共に、隙間２０６８の第２方向中央側では、異物除去エレメント２１０６における障壁部２０３６Ｂの反対側に導くことができる。 Here, in the present embodiment, the flow change portion 2162 is in a state of being spaced from the side wall portions 2036D and 2036E. Therefore, the fuel passing near the side wall portions 2036D and 2036E can be guided to the barrier portion 2036B side of the foreign matter removing element 2106, and on the second direction center side of the gap 2068, the opposite of the barrier portion 2036B of the foreign matter removing element 2106. Can lead to the side.
　なお、変流部２１６２の構成は、上述したものに限らず、オリフィス等を適宜用いて燃料の流れる向きを変更する構成としてもよい。 The configuration of the current change section 2162 is not limited to that described above, and may be a configuration in which the direction in which the fuel flows is changed by appropriately using an orifice or the like.
