Description

本発明は、コントロールバルブ装置に関する。 The present invention relates to a control valve device.

従来から、自動車には、自動変速機が搭載された自動車がある。自動変速機の作動は、コントロールバルブ装置により制御される。コントロールバルブ装置は、例えば、駆動用のオイルが通過する油路（油圧回路）を有するバルブボディと、油路の途中に配置されるフィルタとを備える（例えば、特許文献１参照）。特許文献１に記載のコントロールバルブ装置のバルブボディは、アッパボディとロアボディとが積層されてなる。また、アッパボディとロアボディとが積層されることにより、油路が形成される。油路には、直径が比較的小さい部分があり、当該部分に円筒状のフィルタが取り付けられる（圧入される）。 Conventionally, there are automobiles equipped with an automatic transmission. The operation of the automatic transmission is controlled by the control valve device. The control valve device includes, for example, a valve body having an oil passage (hydraulic circuit) through which driving oil passes, and a filter arranged in the middle of the oil passage (see, for example, Patent Document 1). The valve body of the control valve device described in Patent Document 1 is formed by laminating an upper body and a lower body. Further, an oil passage is formed by laminating the upper body and the lower body. The oil passage has a part having a relatively small diameter, and a cylindrical filter is attached (press-fitted) to the part.

<First Embodiment>
A first embodiment of the control valve device of the present invention will be described with reference to FIGS. 1 to 6. In the following, for convenience of explanation, the X-axis, the Y-axis, and the Z-axis are set as the three axes orthogonal to each other. As an example, the XY plane including the X-axis and the Y-axis is horizontal, and the Z-axis is vertical. The direction of the arrows on the X-axis, Y-axis, and Z-axis is referred to as the "positive side", and the opposite direction is referred to as the "negative side". Further, the direction parallel to the X axis is sometimes referred to as the "first axis O1 direction (axial direction)", and the direction parallel to the Z axis is sometimes referred to as the "second axis O2 direction". In the present specification, the vertical direction, the horizontal direction, the upper side and the lower side are simply names for explaining the relative positional relationship of each part, and the actual arrangement relationship and the like are the arrangement relationship and the like indicated by these names. The arrangement relationship may be other than the above.

図１に示すコントロールバルブ装置１は、例えば自動車等の車両に搭載され、変速機構の作動を制御することができる。コントロールバルブ装置１は、第１ボディ２と、第２ボディ３と、フィルタ部材４と、弁体１１と、ソレノイド１３とを備える。
第１ボディ２は、例えばダイキャストにより製造された板状をなす部材である。第１ボディ２は、厚さ方向をＺ軸方向と平行にして、Ｚ軸方向負側、すなわち、下側（一方側）に主平面２１を有する。図２に示すように、第１ボディ２は、液体Ｑが通過する第１流路２２を有する。なお、液体Ｑは、例えば本実施形態のようにコントロールバルブ装置１が車両の変速機構の作動を制御する場合、作動流体としてのオイルとすることができる。 The control valve device 1 shown in FIG. 1 can be mounted on a vehicle such as an automobile and can control the operation of the transmission mechanism. The control valve device 1 includes a first body 2, a second body 3, a filter member 4, a valve body 11, and a solenoid 13.
The first body 2 is, for example, a plate-shaped member manufactured by die casting. The first body 2 has a main plane 21 on the negative side in the Z-axis direction, that is, on the lower side (one side) with the thickness direction parallel to the Z-axis direction. As shown in FIG. 2, the first body 2 has a first flow path 22 through which the liquid Q passes. The liquid Q can be oil as a working fluid when the control valve device 1 controls the operation of the speed change mechanism of the vehicle as in the present embodiment, for example.

第１ボディ２の主平面２１側には、第２ボディ３が第１ボディ２の厚さ方向に重ねて配置される。第２ボディ３は、第１ボディ２と同様に、例えばダイキャストにより製造された板状をなす部材である。第２ボディ３は、厚さ方向をＺ軸方向と平行にして、Ｚ軸方向正側、すなわち、上側に主平面３１を有する。第２ボディ３は、液体Ｑが通過する第２流路３２を有する。 On the main plane 21 side of the first body 2, the second body 3 is arranged so as to be overlapped in the thickness direction of the first body 2. Like the first body 2, the second body 3 is a plate-shaped member manufactured by, for example, die-casting. The second body 3 has a main plane 31 on the positive side in the Z-axis direction, that is, on the upper side, with the thickness direction parallel to the Z-axis direction. The second body 3 has a second flow path 32 through which the liquid Q passes.

また、第１流路２２の一部は、主平面２１に開口しており、第２流路３２の一部も、主平面３１に開口する。そして、第１流路２２と第２流路３２とは、各開口部同士を介して、つながる。これにより、液体Ｑは、第１流路２２と第２流路３２とを行き来することができる。 Further, a part of the first flow path 22 is opened in the main plane 21, and a part of the second flow path 32 is also opened in the main plane 31. Then, the first flow path 22 and the second flow path 32 are connected to each other via the openings. As a result, the liquid Q can move back and forth between the first flow path 22 and the second flow path 32.

図２に示すように、第１流路２２の途中には、フィルタ部材４が配置される。フィルタ部材４は、液体Ｑに混在する金属片等の異物（コンタミ）を捕捉することができる。本実施形態では、第１ボディ２が複数の第１流路２２を有し、各第１流路２２にフィルタ部材４が配置される。これにより、コントロールバルブ装置１は、複数のフィルタ部材４を備えた状態となる（図１参照）。 As shown in FIG. 2, a filter member 4 is arranged in the middle of the first flow path 22. The filter member 4 can capture foreign matter (contamination) such as metal pieces mixed in the liquid Q. In the present embodiment, the first body 2 has a plurality of first flow paths 22, and the filter member 4 is arranged in each of the first flow paths 22. As a result, the control valve device 1 is provided with a plurality of filter members 4 (see FIG. 1).

また、フィルタ部材４と同様に、各第１流路２２の途中には、柱状の弁体１１が配置されている。弁体１１は、後述する弁体収納部５内を移動することにより、弁体収納部５とフィルタ部材収納部６との間の液体Ｑの通過と、液体Ｑの通過停止とを切り替えるスプール弁体である。 Further, similarly to the filter member 4, a columnar valve body 11 is arranged in the middle of each first flow path 22. The valve body 11 is a spool valve that switches between the passage of the liquid Q and the stop of the passage of the liquid Q between the valve body storage portion 5 and the filter member storage portion 6 by moving in the valve body storage portion 5 described later. The body.

図１に示すように、第１ボディ２の主平面２１と反対側、すなわち、上側には、ソレノイド１３がＸ軸方向正側から接続される接続部２３が設けられる。接続部２３は、各弁体１１に対応して、すなわち、弁体１１の配置数分、設けられる。そして、各接続部２３に接続されたソレノイド１３は、それぞれ、通電より磁力を生じさせて、当該ソレノイド１３に対応する弁体１１を移動させることができる。なお、ソレノイド１３の構成としては、特に限定されず、例えば、円筒状のボビンと、ボビンの外周部に巻回されたコイル等を有する構成とすることができる。 As shown in FIG. 1, a connecting portion 23 to which the solenoid 13 is connected from the positive side in the X-axis direction is provided on the side opposite to the main plane 21 of the first body 2, that is, on the upper side. The connection portion 23 is provided corresponding to each valve body 11, that is, for the number of arrangements of the valve bodies 11. Then, each of the solenoids 13 connected to each connection portion 23 can generate a magnetic force by energization to move the valve body 11 corresponding to the solenoid 13. The configuration of the solenoid 13 is not particularly limited, and may be, for example, a configuration having a cylindrical bobbin, a coil wound around the outer peripheral portion of the bobbin, and the like.

前述したように、第１ボディ２は、複数の第１流路２２を有する。各第１流路２２は、配置箇所が異なること以外は、同じ構成であるため、以下、１つの第１流路２２、および、この第１流路２２に配置されるフィルタ部材４について、代表的に説明する。
図２に示すように、第１流路２２は、弁体１１を収納する弁体収納部５と、フィルタ部材４を収納するフィルタ部材収納部６とを備える。 As described above, the first body 2 has a plurality of first flow paths 22. Since each of the first flow paths 22 has the same configuration except that the arrangement location is different, the following is representative of one first flow path 22 and the filter member 4 arranged in the first flow path 22. To explain.
As shown in FIG. 2, the first flow path 22 includes a valve body accommodating portion 5 for accommodating the valve body 11 and a filter member accommodating portion 6 for accommodating the filter member 4.

図３に示すように、弁体収納部５は、主平面２１（ＸＹ平面）と平行、すなわち、本実施形態ではＸ軸と平行な第１軸Ｏ１方向に沿って設けられる。弁体収納部５内では、弁体１１は、第１軸Ｏ１方向に移動可能、すなわち、Ｘ軸方向正側と負側とに往復動可能に収納される。 As shown in FIG. 3, the valve body accommodating portion 5 is provided along the first axis O1 direction parallel to the main plane 21 (XY plane), that is, parallel to the X axis in the present embodiment. In the valve body accommodating portion 5, the valve body 11 is accommodating in the first axis O1 direction, that is, reciprocating between the positive side and the negative side in the X axis direction.

弁体収納部５は、第１軸Ｏ１方向に沿って交互に配置された複数の大径部５１と複数の小径部５２とを有する。なお、大径部５１および小径部５２の配置数は、それぞれ、１つ以上であれば、特に限定されない。
各大径部５１の直径φｄ５１は、弁体１１の外径φｄ１１よりも大きい。これにより、各大径部５１と弁体１１の外周部との間には、間隙５１１が設けられる。なお、各大径部５１の直径φｄ５１は、互いに同じ大きさであってもよいし、異なる大きさであってもよい。 The valve body accommodating portion 5 has a plurality of large-diameter portions 51 and a plurality of small-diameter portions 52 that are alternately arranged along the direction of the first axis O1. The number of arrangements of the large diameter portion 51 and the small diameter portion 52 is not particularly limited as long as it is one or more.
The diameter φd51 of each large diameter portion 51 is larger than the outer diameter φd11 of the valve body 11. As a result, a gap 511 is provided between each large diameter portion 51 and the outer peripheral portion of the valve body 11. The diameter φd51 of each large diameter portion 51 may have the same size or different sizes.

各小径部５２の直径φｄ５２は、大径部５１の直径φｄ５１よりも直径が小さく、いずれも、弁体１１の外径φｄ１１と同じ大きさである。これにより、各小径部５２は、弁体１１の外周部に接することができる。そして、各小径部５２と弁体１１とが接することにより、弁体１１は、第１軸Ｏ１方向に移動する際に、その移動方向に向かって円滑に案内されることとなる。 The diameter φd52 of each small diameter portion 52 is smaller than the diameter φd51 of the large diameter portion 51, and both have the same size as the outer diameter φd11 of the valve body 11. As a result, each small diameter portion 52 can come into contact with the outer peripheral portion of the valve body 11. Then, when each small diameter portion 52 comes into contact with the valve body 11, the valve body 11 is smoothly guided in the moving direction when moving in the direction of the first axis O1.

図２に示すように、フィルタ部材収納部６は、主平面２１と交差し（直交し）、第１軸Ｏ１とねじれの位置の関係にある第２軸Ｏ２に沿って設けられる。本実施形態では、第２軸Ｏ２は、Ｚ軸と平行となる。また、図３に示すように、フィルタ部材収納部６は、複数の大径部５１のうちの１つの大径部５１に向かって開口する開口部６１を有する。これにより、フィルタ部材収納部６は、開口部６１を介して、弁体収納部５（大径部５１）とつながる。フィルタ部材収納部６と弁体収納部５とがつながることにより、液体Ｑは、弁体収納部５からフィルタ部材収納部６に向かって、またはその反対に、フィルタ部材収納部６から弁体収納部５に向かって流れることができる（図２参照）。 As shown in FIG. 2, the filter member accommodating portion 6 is provided along the second axis O2 which intersects (orthogonally) the main plane 21 and has a twisted position with the first axis O1. In this embodiment, the second axis O2 is parallel to the Z axis. Further, as shown in FIG. 3, the filter member accommodating portion 6 has an opening 61 that opens toward one of the large diameter portions 51 among the plurality of large diameter portions 51. As a result, the filter member accommodating portion 6 is connected to the valve body accommodating portion 5 (large diameter portion 51) via the opening 61. By connecting the filter member storage unit 6 and the valve body storage unit 5, the liquid Q is stored in the valve body from the filter member storage unit 6 toward the filter member storage unit 6 or vice versa. It can flow toward the portion 5 (see FIG. 2).

フィルタ部材収納部６は、幅一定部６３と、幅漸増部６４とを有する。
幅一定部６３は、フィルタ部材収納部６の第２軸Ｏ２と直交し、Ｙ軸方向と平行な幅Ｗ６Ｙが第２軸Ｏ２方向に沿って一定の部分である。
幅一定部６３よりも主平面２１側、すなわち、Ｚ軸方向負側には、幅漸増部６４が設けられる。幅漸増部６４は、幅Ｗ６Ｙが主平面２１側に向かって漸増する部分である。また、幅漸増部６４は、主平面２１に開口する。 The filter member accommodating portion 6 has a constant width portion 63 and a width gradual increase portion 64.
The constant width portion 63 is a portion in which the width W6Y orthogonal to the second axis O2 of the filter member accommodating portion 6 and parallel to the Y-axis direction is constant along the second axis O2 direction.
A width gradual increase portion 64 is provided on the main plane 21 side, that is, on the negative side in the Z-axis direction with respect to the width constant portion 63. The width gradual increase portion 64 is a portion where the width W6Y gradually increases toward the main plane 21 side. Further, the width gradual increase portion 64 opens in the main plane 21.

なお、幅一定部６３および幅一定部６３は、いずれも、フィルタ部材収納部６の第２軸Ｏ２と直交し、Ｘ軸方向と平行な幅Ｗ６Ｘは、互いに同じであり、第２軸Ｏ２方向に沿って一定である。
また、幅一定部６３の第２軸Ｏ２に沿った全長Ｌ６３と、幅漸増部６４の第２軸Ｏ２に沿った全長Ｌ６４との大小関係は、特に限定されないが、本実施形態では、全長Ｌ６３よりも全長Ｌ６４の方が長い。 Both the constant width portion 63 and the constant width portion 63 are orthogonal to the second axis O2 of the filter member accommodating portion 6, and the width W6X parallel to the X-axis direction is the same as each other, and the second axis O2 direction. It is constant along.
Further, the magnitude relationship between the total length L63 along the second axis O2 of the constant width portion 63 and the total length L64 along the second axis O2 of the width gradual increase portion 64 is not particularly limited, but in the present embodiment, the total length L63 The total length L64 is longer than that.

フィルタ部材収納部６の幅一定部６３には、フィルタ部材４が配置される。フィルタ部材４は、１枚の帯状の部材に機械加工を施して得られた加工品である。これにより、フィルタ部材４を簡単な構成とする、すなわち、フィルタ部材４を構成する部品点数を抑えることができ、よって、コントロールバルブ装置１の製造コストの削減を図ることができる。なお、フィルタ部材４は、例えば、ステンレス鋼等のような弾性を有する金属材料で構成される。そして、フィルタ部材４を製造するには、前記金属材料で構成された帯状の部材に対し、プレス機等を用いて、弾性限界を超えて塑性変形を施すことにより、フィルタ部材の製造が可能となる。 The filter member 4 is arranged in the constant width portion 63 of the filter member accommodating portion 6. The filter member 4 is a processed product obtained by machining one strip-shaped member. As a result, the filter member 4 has a simple structure, that is, the number of parts constituting the filter member 4 can be suppressed, and thus the manufacturing cost of the control valve device 1 can be reduced. The filter member 4 is made of an elastic metal material such as stainless steel. Then, in order to manufacture the filter member 4, it is possible to manufacture the filter member by plastically deforming the strip-shaped member made of the metal material beyond the elastic limit by using a press machine or the like. Become.

図６に示すように、フィルタ部材４は、平板状部４１と、弾性部４２と、受圧部４３とを備える。
図４、図５に示すように、平板状部４１は、開口部６１の開口面積よりも大きい平板状をなす部分である。これにより、平板状部４１は、フィルタ部材収納部６内で開口部６１を十分に覆う（塞ぐ）ことができとともに、開口部６１の縁部に面接触することができる。 As shown in FIG. 6, the filter member 4 includes a flat plate-shaped portion 41, an elastic portion 42, and a pressure receiving portion 43.
As shown in FIGS. 4 and 5, the flat plate-shaped portion 41 is a flat plate-shaped portion larger than the opening area of the opening 61. As a result, the flat plate-shaped portion 41 can sufficiently cover (close) the opening 61 in the filter member accommodating portion 6 and can come into surface contact with the edge portion of the opening 61.

また、平板状部４１は、前記平板の厚さ方向、すなわち、Ｙ軸方向に貫通し、開口部６１に臨む複数の貫通孔４１１を有する。これにより、液体Ｑが各貫通孔４１１を通過する際、液体Ｑに混在する金属片等の異物を各貫通孔４１１で捕捉することができる。また、平板状部４１が開口部６１の縁部に面接触することにより、前記異物が各貫通孔４１１を通過せずに、液体Ｑとともに平板状部４１を迂回して流れていくのを防止することができる。これにより、平板状部４１での異物の捕捉漏れを防止することができる。なお、各貫通孔４１１の形状は、本実施形態では円形であるが、これに限定されず、例えば、四角形等の多角形であってもよい。 Further, the flat plate-shaped portion 41 has a plurality of through holes 411 that penetrate in the thickness direction of the flat plate, that is, in the Y-axis direction and face the opening 61. As a result, when the liquid Q passes through each through hole 411, foreign matter such as a metal piece mixed in the liquid Q can be captured by each through hole 411. Further, since the flat plate-shaped portion 41 comes into surface contact with the edge portion of the opening 61, it is possible to prevent the foreign matter from flowing around the flat plate-shaped portion 41 together with the liquid Q without passing through the through holes 411. can do. As a result, it is possible to prevent the flat plate-shaped portion 41 from catching and leaking foreign matter. The shape of each through hole 411 is circular in the present embodiment, but is not limited to this, and may be a polygon such as a quadrangle.

図６に示すように、弾性部４２は、平板状部４１のＺ軸方向正側から負側に向かって折れ曲がって設けられる。そして、図４、図５に示すように、弾性部４２は、開口部６１と反対側で平板状部４１に対向して配置される。また、弾性部４２は、フィルタ部材収納部６の内壁面（内周面）６２のうち、幅一定部６３に位置するＹ軸方向正側の面６２１に接して、平板状部４１との間隔Ｗ４が減少する方向に弾性変形する。これにより、弾性部４２が平板状部４１を開口部６１側に押し付ける弾性力Ｆ４２、すなわち、Ｙ軸方向負側への力を平板状部４１に付与することができ、よって、フィルタ部材４が幅一定部６３に保持される。 As shown in FIG. 6, the elastic portion 42 is provided by being bent from the positive side to the negative side in the Z-axis direction of the flat plate-shaped portion 41. Then, as shown in FIGS. 4 and 5, the elastic portion 42 is arranged on the opposite side of the opening 61 and facing the flat plate-shaped portion 41. Further, the elastic portion 42 is in contact with the surface 621 on the positive side in the Y-axis direction located on the constant width portion 63 of the inner wall surface (inner peripheral surface) 62 of the filter member accommodating portion 6, and is spaced from the flat plate-shaped portion 41. It elastically deforms in the direction in which W4 decreases. As a result, the elastic force F42 in which the elastic portion 42 presses the flat plate-shaped portion 41 toward the opening 61 side, that is, a force in the negative side in the Y-axis direction can be applied to the flat plate-shaped portion 41, whereby the filter member 4 can apply. It is held by the constant width portion 63.

なお、幅一定部６３内では、弾性力Ｆ４２が最大となる。
また、液体Ｑが弁体収納部５からフィルタ部材収納部６に向かって流れた際、弾性力Ｆ４２は、液体Ｑが平板状部４１に作用するＹ軸方向正側への力よりも大きく設定される。これにより、液体Ｑの流量の大小にかかわらず、フィルタ部材収納部６内でのフィルタ部材４の位置ズレが防止され、よって、フィルタ部材４がフィルタ部材収納部６内で安定して収納された状態となる。 The elastic force F42 is maximized within the constant width portion 63.
Further, when the liquid Q flows from the valve body storage portion 5 toward the filter member storage portion 6, the elastic force F42 is set to be larger than the force on the positive side in the Y-axis direction in which the liquid Q acts on the flat plate-shaped portion 41. Will be done. As a result, the position of the filter member 4 in the filter member storage portion 6 is prevented from being displaced regardless of the flow rate of the liquid Q, so that the filter member 4 is stably stored in the filter member storage portion 6. It becomes a state.

第１ボディ２とフィルタ部材４とを組み立てる、すなわち、第１ボディ２のフィルタ部材収納部６にフィルタ部材４を収納、配置する際には、まず、フィルタ部材４を幅漸増部６４からフィルタ部材収納部６に挿入する。前述したように幅漸増部６４は、幅Ｗ６Ｙが主平面２１側に向かって漸増する。これにより、幅漸増部６４へのフィルタ部材４の挿入作業を容易に行うことができる。なお、フィルタ部材４は、幅漸増部６４を通過中、平板状部４１と弾性部４２との間隔Ｗ４が徐々に減少していく。また、図４、図５に示すように、フィルタ部材４の挿入作業は、棒状の工具１２を用いて行うのが好ましい。これにより、挿入作業を容易に行うことができる。 When assembling the first body 2 and the filter member 4, that is, when storing and arranging the filter member 4 in the filter member accommodating portion 6 of the first body 2, the filter member 4 is first moved from the width gradual increasing portion 64 to the filter member. Insert into the storage unit 6. As described above, in the width gradual increase portion 64, the width W6Y gradually increases toward the main plane 21 side. As a result, the work of inserting the filter member 4 into the width gradual increase portion 64 can be easily performed. As the filter member 4 passes through the width gradually increasing portion 64, the distance W4 between the flat plate-shaped portion 41 and the elastic portion 42 gradually decreases. Further, as shown in FIGS. 4 and 5, it is preferable that the filter member 4 is inserted by using the rod-shaped tool 12. Thereby, the insertion work can be easily performed.

そして、挿入作業を継続していくと、フィルタ部材４は、幅漸増部６４を超えて、幅一定部６３に到達する。前述したように、幅一定部６３は、幅Ｗ６Ｙが第２軸Ｏ２方向に沿って一定である。これにより、幅一定部６３では、弾性力Ｆ４２が最大状態で一定となり、よって、フィルタ部材４が安定して配置される。 Then, as the insertion work is continued, the filter member 4 exceeds the width gradual increase portion 64 and reaches the width constant portion 63. As described above, the width W6Y of the width constant portion 63 is constant along the second axis O2 direction. As a result, in the constant width portion 63, the elastic force F42 becomes constant in the maximum state, and thus the filter member 4 is stably arranged.

また、フィルタ部材収納部６は、Ｚ軸方向正側に規制部６５を有する。規制部６５は、フィルタ部材収納部６の上面（天面）であり、フィルタ部材４のＺ軸方向正側（主平面２１と反対側）にある先端折り曲げ部４２２が接触して、フィルタ部材４のＺ軸方向正側への移動を規制する、すなわち、フィルタ部材４の挿入限界を規制することができる。これにより、フィルタ部材収納部６内にフィルタ部材４を過不足なく挿入する、すなわち、フィルタ部材４を幅一定部６３に正確に配置することができる。 Further, the filter member accommodating portion 6 has a regulating portion 65 on the positive side in the Z-axis direction. The regulating portion 65 is the upper surface (top surface) of the filter member accommodating portion 6, and the tip bending portion 422 on the positive side in the Z-axis direction (opposite to the main plane 21) of the filter member 4 comes into contact with the filter member 4 It is possible to regulate the movement of the filter member 4 to the positive side in the Z-axis direction, that is, to regulate the insertion limit of the filter member 4. As a result, the filter member 4 can be inserted into the filter member accommodating portion 6 without excess or deficiency, that is, the filter member 4 can be accurately arranged in the constant width portion 63.

このように、第１ボディ２とフィルタ部材４とを組み立てる際には、フィルタ部材４を比較的細い（狭い）フィルタ部材収納部６に挿入し、フィルタ部材４がそのままの姿勢でフィルタ部材収納部６の規制部６５に当接するまで、フィルタ部材４を押し込むという簡単な作業で、組み立てを容易かつ迅速に行うことができる。従って、コントロールバルブ装置１は、組立作業性に優れ、製造コストの低減を可能とする置となっている。 In this way, when assembling the first body 2 and the filter member 4, the filter member 4 is inserted into the relatively thin (narrow) filter member accommodating portion 6, and the filter member 4 remains in the same posture as the filter member accommodating portion. Assembling can be performed easily and quickly by a simple operation of pushing the filter member 4 until it comes into contact with the regulation portion 65 of 6. Therefore, the control valve device 1 is excellent in assembly workability and can reduce the manufacturing cost.

図４、図５に示すように、弾性部４２は、フィルタ部材収納部６の内壁面６２に接する部分が、内壁面６２と線接触可能に円弧状に湾曲した湾曲部４２１で構成される。これにより、フィルタ部材４をフィルタ部材収納部６に挿入する際、フィルタ部材４とフィルタ部材収納部６の内壁面６２との摩擦をできる限り抑制することができ、よって、その挿入作業を容易行うことができる。 As shown in FIGS. 4 and 5, the elastic portion 42 is composed of a curved portion 421 in which a portion of the filter member accommodating portion 6 in contact with the inner wall surface 62 is curved in an arc shape so as to be in line contact with the inner wall surface 62. As a result, when the filter member 4 is inserted into the filter member accommodating portion 6, friction between the filter member 4 and the inner wall surface 62 of the filter member accommodating portion 6 can be suppressed as much as possible, and thus the insertion work can be facilitated. be able to.

また、図６に示すように、平板状部４１と弾性部４２との間隔Ｗ４は、湾曲部４２１からＺ軸方向正側（主平面２１と反対側）に向かって漸減する。これにより、フィルタ部材４は、Ｚ軸方向正側に向かって先が細い先細り形状となる。先細り形状により、フィルタ部材収納部６へのフィルタ部材４の挿入作業を容易に行うことができる。 Further, as shown in FIG. 6, the distance W4 between the flat plate-shaped portion 41 and the elastic portion 42 gradually decreases from the curved portion 421 toward the positive side in the Z-axis direction (opposite side to the main plane 21). As a result, the filter member 4 has a tapered shape that tapers toward the positive side in the Z-axis direction. Due to the tapered shape, the work of inserting the filter member 4 into the filter member storage portion 6 can be easily performed.

受圧部４３は、弾性部４２と反対側で平板状部４１からＹ軸方向正側に折れ曲がって設けられる。そして、図４、図５に示すように、受圧部４３は、フィルタ部材４をフィルタ部材収納部６に第２軸Ｏ２に沿って挿入する際に用いられる工具１２からの力を受けることができる。これにより、フィルタ部材４が工具１２からの力を十分に受けることができ、よって、フィルタ部材収納部６へのフィルタ部材４の挿入作業を迅速に行うことができる。なお、受圧部４３は、本実施形態では平板状部４１から直角に折れ曲がっているが、折れ曲がり角度については、特に限定されない。 The pressure receiving portion 43 is provided so as to be bent from the flat plate-shaped portion 41 to the positive side in the Y-axis direction on the side opposite to the elastic portion 42. Then, as shown in FIGS. 4 and 5, the pressure receiving portion 43 can receive the force from the tool 12 used when inserting the filter member 4 into the filter member accommodating portion 6 along the second axis O2. .. As a result, the filter member 4 can sufficiently receive the force from the tool 12, and therefore, the work of inserting the filter member 4 into the filter member accommodating portion 6 can be performed quickly. In the present embodiment, the pressure receiving portion 43 is bent at a right angle from the flat plate-shaped portion 41, but the bending angle is not particularly limited.

フィルタ部材４が自然状態（外力が付与しない状態）であるか、または、フィルタ部材４がフィルタ部材収納部６に収納された状態であるかに関わらず、受圧部４３と弾性部４２とは、離間した状態となる。これにより、フィルタ部材４がフィルタ部材収納部６に収納された状態で、液体Ｑが受圧部４３と弾性部４２とを通過することができ、よって、フィルタ部材４が液体Ｑの通過を妨げるのを防止することができる。また、フィルタ部材４がフィルタ部材収納部６の幅Ｗ６Ｙに応じて、拡大、縮小することができる。これにより、フィルタ部材４の挿入作業を円滑に行うことができる。 Regardless of whether the filter member 4 is in a natural state (a state in which no external force is applied) or the filter member 4 is stored in the filter member storage portion 6, the pressure receiving portion 43 and the elastic portion 42 are separated from each other. It will be in a separated state. As a result, the liquid Q can pass through the pressure receiving portion 43 and the elastic portion 42 while the filter member 4 is housed in the filter member accommodating portion 6, and thus the filter member 4 prevents the passage of the liquid Q. Can be prevented. Further, the filter member 4 can be enlarged or reduced according to the width W6Y of the filter member accommodating portion 6. As a result, the insertion work of the filter member 4 can be smoothly performed.
