Description

本発明は、流体流路に装着されたフィルタを備えたフィルタ装置に関する。   The present invention relates to a filter device including a filter attached to a fluid flow path.

上記フィルタ装置は、流体に混入している異物の流体供給先や流体ポンプなどへの流入を防止するために、異物を捕捉するためのフィルタを流体流路に装着してある（例えば、特許文献１参照）。   In the filter device, a filter for capturing foreign matter is attached to a fluid flow path in order to prevent foreign matters mixed in the fluid from flowing into a fluid supply destination or a fluid pump (for example, Patent Documents). 1).

特開２０１０−１７７０６号公報JP 2010-17706 A

このため、フィルタで捕捉された異物が当該フィルタの流体流れ方向上手側の流体流路内に滞留し、流体通過量の累積にともなって、流体流れ方向上手側の流体流路内における異物の滞留量も累積して、フィルタの目詰まりが早期に生じ易い欠点がある。
本発明は上記実情に鑑みてなされたものであって、フィルタの目詰まりが長期に亘って生じ難いフィルタ装置を提供することを目的とする。 For this reason, the foreign matter captured by the filter stays in the fluid flow path on the upper side of the filter in the fluid flow direction, and the accumulation of the foreign matter in the fluid flow path on the upper side of the fluid flow direction accompanies the accumulation of the fluid passage amount. The amount is also accumulated, and there is a drawback that filter clogging tends to occur early.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a filter device in which filter clogging is unlikely to occur over a long period of time.

本発明のフィルタ装置の第１特徴構成は、流体流路に装着され、流体流れ方向上手側に下向き面を有するフィルタと、前記下向き面に対向し、かつ、前記流体流路に臨む開口を有する凹入部とを備えた点にある。   The first characteristic configuration of the filter device of the present invention includes a filter that is attached to a fluid flow path and has a downward surface on the upper side in the fluid flow direction, and an opening that faces the downward surface and faces the fluid flow path. It is in the point provided with the recessed part.

本構成のフィルタ装置は、フィルタの下向き面に対して流体流れ方向上手側において対向し、かつ、流体流路に臨む開口を有する凹入部を備えている。
このため、フィルタの下向き面に捕捉された異物を、流体の流動を停止したときなどに凹入部に流入させて、フィルタの流体流れ方向上手側における流体流路内に滞留しないように貯留し易い。
つまり、流体の流動を停止したときや流体の流速が遅いときなどには、フィルタの下向き面に捕捉された異物が自重で流体流路内を下降移動し易い点に着目し、これらの下降移動する異物をフィルタの下向き面に対して対向し、かつ、流体流路に臨む開口に向けて自重で下降移動させて、凹入部に流入させ易い。
したがって、フィルタで捕捉された異物が当該フィルタの流体流れ方向上手側の流体流路内に滞留し難くなり、流体通過量の累積に伴う異物の滞留量の累積も少ない。
よって、本構成のフィルタ装置であれば、フィルタの目詰まりが長期に亘って生じ難い。 The filter device of this configuration is provided with a recessed portion having an opening facing the fluid flow path and facing the lower surface of the filter on the upper side in the fluid flow direction.
For this reason, it is easy to store the foreign matter captured on the downward surface of the filter so that it does not stay in the fluid flow path on the upper side in the fluid flow direction of the filter by flowing into the recessed portion when the fluid flow is stopped. .
In other words, when the fluid flow is stopped or when the fluid flow rate is slow, pay attention to the fact that foreign matter trapped on the downward surface of the filter tends to move down in the fluid flow path by its own weight. It is easy to allow the foreign matter to be moved downward by its own weight toward the opening facing the fluid flow path, facing the downward surface of the filter, and flowing into the recessed portion.
Accordingly, the foreign matter captured by the filter is less likely to stay in the fluid flow path on the upper side of the filter in the fluid flow direction, and the accumulation amount of the foreign matter accompanying the accumulation of the fluid passage amount is small.
Therefore, with the filter device of this configuration, the filter is not easily clogged for a long time.

本発明の第２特徴構成は、前記凹入部が奥拡がり形状に形成されている点にある。   The 2nd characteristic structure of this invention exists in the point by which the said recessed part is formed in the back spreading shape.

本構成のフィルタ装置であれば、凹入部に流入した異物が流体流路に流れ出し難く、異物が流体流路内に滞留し難い状態を維持し易い。   With the filter device of this configuration, the foreign matter that has flowed into the recessed portion is difficult to flow out into the fluid flow path, and it is easy to maintain a state in which the foreign matter is less likely to stay in the fluid flow path.

本発明の第３特徴構成は、前記フィルタが横向きの流体流路に装着され、前記下向き面が、流体流れ方向下手側ほど前記開口の側に近づく姿勢で配設されている点にある。   According to a third characteristic configuration of the present invention, the filter is mounted in a lateral fluid flow path, and the downward surface is disposed in a posture closer to the opening side toward the lower side in the fluid flow direction.

本構成のフィルタ装置であれば、フィルタの下向き面と凹入部の開口とを流体流路の径方向で対向させることができ、下向き面から開口までの異物の移動距離を短く設定して凹入部への流入を促進し易い。
また、フィルタの下向き面を広く設定して、フィルタに対する流体の通過抵抗を少なくすることができる。 In the filter device of this configuration, the downward surface of the filter and the opening of the recessed portion can be opposed to each other in the radial direction of the fluid flow path, and the moving distance of the foreign matter from the downward surface to the opening can be set to be short. It is easy to promote inflow.
Moreover, the downward surface of the filter can be set wide to reduce the passage resistance of the fluid to the filter.

本発明の第４特徴構成は、前記流体流路における流体流れ方向を逆方向に切換可能な逆洗機構が設けられている点にある。   A fourth characteristic configuration of the present invention is that a backwashing mechanism capable of switching the fluid flow direction in the fluid flow path in the reverse direction is provided.

本構成のフィルタ装置であれば、流体流路における流体流れ方向を逆方向に切り換えることにより、フィルタで捕捉された異物をフィルタから強制的に洗い流すことができ、フィルタの目詰まりが一層生じ難い。   With the filter device of this configuration, the foreign matter captured by the filter can be forcibly washed away from the filter by switching the fluid flow direction in the fluid flow path to the opposite direction, and the filter is less likely to be clogged.

チェーンカバーＥ２はアルミニウム合金等の鋳造品で構成してある。
吸入油路５と吐出油路７は、チェーンカバーＥ２にドリル加工等によって穿孔された円形孔部によって形成されている。
チェーンカバーＥ２の内面側にはポンプ固定座９を形成してあり、このポンプ固定座９に電動ポンプＰが着脱自在に固定されている。 The chain cover E2 is made of a cast product such as an aluminum alloy.
The suction oil passage 5 and the discharge oil passage 7 are formed by circular holes that are drilled in the chain cover E2 by drilling or the like.
A pump fixing seat 9 is formed on the inner surface side of the chain cover E2, and the electric pump P is detachably fixed to the pump fixing seat 9.

電動ポンプＰは、トロコイド型のポンプ本体Ｐ１と、このポンプ本体Ｐ１を駆動する電動モータＰ２とを一体に備えている。
ポンプ本体Ｐ１は、図２に示すように、横向きのロータ回転軸芯Ｘの周りで回転するロータ１０と、このロータ１０を内装しているハウジング１１と、ハウジング１１のロータ回転軸芯Ｘの方向で一端側に円形に開口する、潤滑油ＯＩＬの吸入ポート１２及び吐出ポート１３とを備えている。 The electric pump P is integrally provided with a trochoid pump main body P1 and an electric motor P2 that drives the pump main body P1.
As shown in FIG. 2, the pump body P <b> 1 includes a rotor 10 that rotates around a laterally oriented rotor rotation axis X, a housing 11 that houses the rotor 10, and a direction of the rotor rotation axis X of the housing 11. Are provided with a lubricating oil OIL suction port 12 and a discharge port 13 which are circularly open on one end side.

吸入ポート１２及び吐出ポート１３は、電動ポンプＰをチェーンカバーＥ２に固定することにより、吸入油路５及び吐出油路７に夫々連通接続されている。   The suction port 12 and the discharge port 13 are connected to the suction oil passage 5 and the discharge oil passage 7, respectively, by fixing the electric pump P to the chain cover E2.

吸入油路５のうちの吸入ポート１２に接続される接続油路部分５ａ及び吐出油路７のうちの吐出ポート１３に接続される接続油路部分７ａは、ロータ回転軸芯Ｘの方向に沿う横向きに形成されている。
フィルタ装置Ａは、吸入油路５のうちの横向きに形成されている接続油路部分５ａに装備されている。 The connecting oil passage portion 5a connected to the suction port 12 in the suction oil passage 5 and the connecting oil passage portion 7a connected to the discharge port 13 in the discharge oil passage 7 are along the direction of the rotor rotation axis X. It is formed sideways.
The filter device A is mounted on a connecting oil passage portion 5 a formed in the suction oil passage 5 in the lateral direction.

フィルタ装置Ａは、図２〜図４に示すように、吸入油路５の接続油路部分５ａに装着されたフィルタ１４と、フィルタ１４で捕捉された金属屑（ストレーナ８で捕捉されなかった金属屑）などの異物Ｃを流入させる異物貯留用の凹入部１５とを備えている。
フィルタ１４は、図５にも示すように、網状の金属製フィルタ部材１７を円形リング部材１６の内側に備えている。
フィルタ部材１７は、円形リング部材１６の内周側から円形リング部材１６と同芯で円形のドーム状に突出する凸曲面状（茶漉し網状）に形成されている。 As shown in FIGS. 2 to 4, the filter device A includes a filter 14 attached to the connection oil passage portion 5 a of the suction oil passage 5, and metal scraps captured by the filter 14 (metal not captured by the strainer 8). And a foreign matter storage recess 15 for allowing foreign matter C such as scrap) to flow in.
As shown in FIG. 5, the filter 14 includes a net-like metal filter member 17 inside the circular ring member 16.
The filter member 17 is formed in a convex curved surface shape (branch net shape) that is concentric with the circular ring member 16 and protrudes in a circular dome shape from the inner peripheral side of the circular ring member 16.

フィルタ１４は、フィルタ部材１７を潤滑油流れ方向上手側（潤滑油ＯＩＬが電動ポンプＰに吸入される方向の上手側）に向けて突出させた状態で、接続油路部分５ａの終端側に装着してある。
すなわち、接続油路部分５ａの終端側にフィルタ装着用の段部５ｂを円環状に形成し、この段部５ｂに円形リング部材１６を嵌め込むと共に、円形リング部材１６とポンプ本体Ｐ１との間に弾性シールリング１８を挟み込んで、フィルタ１４を接続油路部分５ａに対して着脱自在に装着してある。 The filter 14 is mounted on the terminal end side of the connecting oil passage portion 5a in a state in which the filter member 17 protrudes toward the upper side in the lubricating oil flow direction (upper side in the direction in which the lubricating oil OIL is sucked into the electric pump P). It is.
That is, a step portion 5b for mounting the filter is formed in an annular shape on the terminal end side of the connecting oil passage portion 5a, and the circular ring member 16 is fitted into the step portion 5b, and between the circular ring member 16 and the pump body P1. The filter 14 is detachably attached to the connecting oil passage portion 5a with the elastic seal ring 18 interposed therebetween.

したがって、接続油路部分５ａに装着されたフィルタ１４は、その潤滑油流れ方向上手側に、フィルタ部材１７の下向き外周面（フィルタ部材１７の外周面のうちの、フィルタ部材１７の中心軸を通る仮想水平面よりも下側の外周面部分）で形成された下向き面１９を有している。   Therefore, the filter 14 attached to the connecting oil passage portion 5a passes the lower outer peripheral surface of the filter member 17 (the central axis of the filter member 17 in the outer peripheral surface of the filter member 17) on the upper side in the lubricating oil flow direction. It has a downward surface 19 formed on the outer peripheral surface portion below the virtual horizontal plane.

凹入部１５は、図２〜図４に示すように、接続油路部分５ａを囲んでいるチェーンカバー部分のうちの、接続油路部分５ａに装着されたフィルタ部材１７の下向き面１９に対してその下側から対向する部位を、接続油路部分５ａの長手方向に沿って、ドリル加工等によって切削して、接続油路部分５ａに開口２０を介して連通する状態で下向きに凹入させた形状に形成してある。   As shown in FIGS. 2 to 4, the recessed portion 15 is formed with respect to the downward surface 19 of the filter member 17 attached to the connecting oil passage portion 5 a in the chain cover portion surrounding the connecting oil passage portion 5 a. The part facing from the lower side was cut by drilling or the like along the longitudinal direction of the connecting oil passage part 5a, and was recessed downward in a state communicating with the connecting oil passage part 5a through the opening 20. It is formed into a shape.

したがって、凹入部１５は、フィルタ部材１７の下向き面１９に対向し、かつ、吸入油路５の接続油路部分５ａに臨む開口２０を有している。
また、フィルタ部材１７の下向き面１９が、潤滑油流れ方向下手側ほど凹入部１５の開口２０の側に近づく姿勢で配設されている。 Therefore, the recessed portion 15 has an opening 20 that faces the downward surface 19 of the filter member 17 and faces the connecting oil passage portion 5 a of the suction oil passage 5.
Further, the downward surface 19 of the filter member 17 is disposed in a posture closer to the opening 20 side of the recessed portion 15 toward the lower side in the lubricating oil flow direction.

凹入部１５は、図３に示すように、開口２０の油路長手方向での最大長さＬ１を凹入部１５の油路長手方向での最大長さＬ２よりも短く設定し、かつ、図４に示すように、開口２０の油路径方向での最大幅Ｂ１を凹入部１５の油路径方向での最大幅Ｂ２よりも短く設定して、奥拡がり形状に形成されている。   As shown in FIG. 3, the recessed portion 15 sets the maximum length L1 of the opening 20 in the oil passage longitudinal direction to be shorter than the maximum length L2 of the recessed portion 15 in the oil passage longitudinal direction, and FIG. As shown, the maximum width B1 of the opening 20 in the oil passage radial direction is set to be shorter than the maximum width B2 of the recessed portion 15 in the oil passage radial direction, and the opening 20 is formed in a deepened shape.

凹入部１５は、電動ポンプＰの側の端部がチェーンカバーＥ２の内側に向けて開口するように形成してある。
したがって、電動ポンプＰをポンプ固定座９から外して、フィルタ１４を吸入油路５から抜き出すことにより、凹入部１５に溜まった異物ＣをチェーンカバーＥ２の内側に向けて容易に掻き出すことができる。 The recessed portion 15 is formed so that the end portion on the electric pump P side opens toward the inside of the chain cover E2.
Therefore, by removing the electric pump P from the pump fixing seat 9 and extracting the filter 14 from the suction oil passage 5, the foreign matter C accumulated in the recessed portion 15 can be easily scraped out toward the inside of the chain cover E2.

フィルタ装置Ａには、吸入油路５における潤滑油流れ方向を逆方向に切換可能な逆洗機構が設けられている。
この逆洗機構は、電動ポンプＰにおけるロータ１０を、吐出油路７内の潤滑油ＯＩＬが逆流する程度の短時間だけ逆向きに回転させることにより、潤滑油ＯＩＬをフィルタ１４に対して逆向きに通過させて、フィルタ１４に捕捉された異物Ｃを吸入油路５の上手側に強制的に洗い流すことができるように構成してある。 The filter device A is provided with a backwashing mechanism capable of switching the lubricating oil flow direction in the suction oil passage 5 in the reverse direction.
This backwash mechanism rotates the rotor 10 in the electric pump P in the reverse direction for a short time such that the lubricating oil OIL in the discharge oil passage 7 flows backward, so that the lubricating oil OIL is reversely directed to the filter 14. The foreign matter C captured by the filter 14 can be forcibly washed away to the upper side of the suction oil passage 5.

〔第２実施形態〕
図６〜図９は、フィルタ装置Ａの別実施形態を示す。
本実施形態では、フィルタ１４を、図９に示すように、平面視で楕円形の扁平なリング部材１６の内側に、平面視で楕円形の扁平なフィルタ部材１７を設けて構成してある。 [Second Embodiment]
6 to 9 show another embodiment of the filter device A. FIG.
In the present embodiment, as shown in FIG. 9, the filter 14 is configured by providing an elliptical flat filter member 17 in plan view inside a flat ring member 16 that is elliptical in plan view.

また、接続油路部分５ａの終端側に、図６に示すように、油路軸芯Ｙに対して上方側ほど油路上手側に位置するように傾斜するフィルタ装着面２１を備えたフィルタ装着用の段部５ｂを形成してある。   Further, as shown in FIG. 6, the filter mounting surface 21 is provided with a filter mounting surface 21 that is inclined so as to be located on the upper side of the oil passage on the terminal side of the connecting oil passage portion 5a. A step portion 5b is formed.

そして、フィルタ１４のリング部材１６を段部５ｂに入り込ませて、そのリング部材１６がフィルタ装着面２１に接当するように、筒状のスペーサ２２を段部５ｂに入り込ませる共に、スペーサ２２と電動ポンプＰとの間に弾性シールリング１８を挟み込んで、フィルタ１４を接続油路部分５ａに対して着脱自在に装着してある。   Then, the ring member 16 of the filter 14 enters the step portion 5b, and the cylindrical spacer 22 enters the step portion 5b so that the ring member 16 contacts the filter mounting surface 21. An elastic seal ring 18 is sandwiched between the electric pump P and the filter 14 is detachably attached to the connecting oil passage portion 5a.

したがって、本実施形態では、フィルタ１４が、フィルタ部材１７の潤滑油流れ方向上手側の全面が下向き面１９となるように、潤滑油流れ方向下手側ほど開口２０の側に近づく姿勢で、接続油路部分５ａに装着されているので、フィルタ部材１７で捕捉された異物Ｃの全体を凹入部１５に流入させ易い。
その他の構成は第１実施形態と同様である。 Therefore, in the present embodiment, the filter 14 is in a posture that approaches the opening 20 side closer to the lower side in the lubricating oil flow direction so that the entire surface on the upper side in the lubricating oil flow direction of the filter member 17 becomes the downward surface 19. Since it is attached to the path portion 5 a, the entire foreign matter C captured by the filter member 17 can easily flow into the recessed portion 15.
Other configurations are the same as those of the first embodiment.
