Description

本発明は、スプール切換弁装置に関するものである。   The present invention relates to a spool switching valve device.

例えば、特許文献１には、自動車の自動変速機等における油圧回路の切換構造が開示されている。特許文献１に記載された切換構造は、二つの入力ポートに対して一つの出力ポートを一組として、長手方向一方側が有底の円筒状の筺体に設けた構造である。筺体の内部には、一端側と他端側一対の弁体および夫々弁座を有する一端側と他端側一対のピストンと、弁体およびピストンを収容する収容部とが設けられている。一方の入力ポート側の油圧が他方の入力ポート側の油圧より高い場合には、ピストンが他方の入力ポート側に移動する。ピストンが移動すると、他方側の弁座が他方の入力ポート側に設けられた弁体に接触して他方の入力ポート側の流路が閉鎖され、一方の入力ポートから導入された油は、筺体内部の流路を通り、出力ポートに導かれる。   For example, Patent Document 1 discloses a hydraulic circuit switching structure in an automatic transmission of an automobile or the like. The switching structure described in Patent Document 1 is a structure in which one output port is set as a set for two input ports and is provided in a cylindrical casing having a bottom on one side in the longitudinal direction. Inside the housing are provided a pair of valve bodies on one end side and the other end side, one end side having a valve seat and a pair of pistons on the other end side, and a housing for housing the valve body and the piston. When the hydraulic pressure on one input port side is higher than the hydraulic pressure on the other input port side, the piston moves to the other input port side. When the piston moves, the valve seat on the other side comes into contact with the valve body provided on the other input port side, the flow path on the other input port side is closed, and the oil introduced from one input port is It passes through the internal flow path and is guided to the output port.

For example, the valve body B <b> 1 is accommodated in the valve body movable portion 22 of the spool housing 10. The valve seat member 60 is mounted on the end portion on the −X side of the spool housing 10 in which the valve body B1 is accommodated. Next, the valve body B <b> 2 is accommodated in the valve body movable portion 32 of the spool housing 10. The valve seat member 70 is attached to the end on the + X side of the spool housing 10 in which the valve body B2 is accommodated.

弁体Ｂ１の弁体可動部２２への収容作業および弁座部材６０のスプール筺体１０への装着作業は、挿入穴８２が上方に向くようにスプール筺体１０を鉛直方向に沿った状態で行うことが好ましい。弁体可動部２２に投入された弁体Ｂ１は自重により第１弁座部２３に保持されるため、弁座部材６０のスプール筺体１０への装着作業を円滑に行うことができる。弁体Ｂ２の弁体可動部３２への収容作業および弁座部材７０のスプール筺体１０への装着作業は、挿入穴１８２が上方に向くようにスプール筺体１０を鉛直方向に沿った状態で行うことが好ましい。弁体可動部３２に投入された弁体Ｂ２は自重により第１弁座部３３に保持されるため、弁座部材７０のスプール筺体１０への装着作業を円滑に行うことができる。   The operation of housing the valve body B1 in the valve body movable portion 22 and the operation of mounting the valve seat member 60 on the spool housing 10 are performed with the spool housing 10 along the vertical direction so that the insertion hole 82 faces upward. Is preferred. Since the valve body B1 thrown into the valve body movable portion 22 is held by the first valve seat portion 23 by its own weight, the operation of mounting the valve seat member 60 to the spool housing 10 can be performed smoothly. The operation of housing the valve body B2 in the valve body movable portion 32 and the operation of mounting the valve seat member 70 on the spool housing 10 are performed with the spool housing 10 along the vertical direction so that the insertion hole 182 faces upward. Is preferred. Since the valve body B2 thrown into the valve body movable portion 32 is held by the first valve seat portion 33 by its own weight, the mounting operation of the valve seat member 70 to the spool housing 10 can be performed smoothly.

スプール筺体１０の弁座装着部８１に弁座部材６０を装着する際には、弁座部材６０の筒部６３を弁座装着部８１に挿入する。筒部６３の先端が段部８１ａに突き当たると、工具を用いて、図７中に矢印ＡＲで示すように、スプール筺体１０の係合部６１を互いに径方向に接近する方向に加締める。係合部６１は、スリットＳ１によってスプール筺体１０と分離され他の箇所よりも強度が低いため、図４および図８に示すように、塑性変形して係合受け部６２に入り込む。係合受け部６２に入り込んだ係合部６１は、弁座部材６０に対してスプール筺体１０からの弁座部材６０の脱落方向である−Ｘ側に位置する。従って、弁座部材６０は、スプール筺体１０からの脱落が阻止される。係合部６１は、径方向で対向して配置されているため、例えば、対向する一対の加圧部を有する工具を用いた加締め作業を効果的に実施することができる。   When the valve seat member 60 is mounted on the valve seat mounting portion 81 of the spool housing 10, the tubular portion 63 of the valve seat member 60 is inserted into the valve seat mounting portion 81. When the tip end of the cylindrical portion 63 hits the stepped portion 81a, the engagement portion 61 of the spool housing 10 is crimped in a direction approaching each other in the radial direction, as indicated by an arrow AR in FIG. Since the engaging portion 61 is separated from the spool housing 10 by the slit S1 and has a lower strength than the other portions, the engaging portion 61 is plastically deformed and enters the engaging receiving portion 62 as shown in FIGS. The engaging portion 61 that has entered the engaging receiving portion 62 is located on the −X side, which is the direction in which the valve seat member 60 is detached from the spool housing 10 with respect to the valve seat member 60. Therefore, the valve seat member 60 is prevented from dropping from the spool housing 10. Since the engaging part 61 is arrange | positioned facing in radial direction, the crimping operation | work using the tool which has a pair of opposing pressurizing part can be implemented effectively, for example.

スプール筺体１０の弁座装着部１８１に弁座部材７０を装着する際には、弁座部材３０の筒部６４を弁座装着部１８１に挿入する。筒部６４の先端が段部１８１ａに突き当たると、工具を用いて、スプール筺体１０の係合部７１を互いに径方向に接近する方向に加締める。係合部７１は、スリットＳ２によってスプール筺体１０と分離され他の箇所よりも強度が低いため、図６に示すように、塑性変形して係合受け部７２に入り込む。係合受け部７２に入り込んだ係合部７１は、弁座部材７０に対してスプール筺体１０からの弁座部材７０の脱落方向である＋Ｘ側に位置する。従って、弁座部材７０は、スプール筺体１０からの脱落が阻止される。係合部７１は、径方向で対向して配置されているため、例えば、対向する一対の加圧部を有する工具を用いた加締め作業を効果的に実施することができる。   When the valve seat member 70 is mounted on the valve seat mounting portion 181 of the spool housing 10, the tubular portion 64 of the valve seat member 30 is inserted into the valve seat mounting portion 181. When the tip end of the cylindrical portion 64 hits the stepped portion 181a, the engaging portion 71 of the spool housing 10 is crimped in a direction approaching each other in the radial direction using a tool. Since the engaging portion 71 is separated from the spool housing 10 by the slit S2 and has a lower strength than other portions, the engaging portion 71 is plastically deformed and enters the engaging receiving portion 72 as shown in FIG. The engaging portion 71 that has entered the engaging receiving portion 72 is located on the + X side, which is the direction in which the valve seat member 70 is dropped from the spool housing 10 with respect to the valve seat member 70. Accordingly, the valve seat member 70 is prevented from dropping from the spool housing 10. Since the engaging part 71 is arrange | positioned facing in radial direction, the crimping operation | work using the tool which has a pair of pressure part which opposes can be implemented effectively, for example.

スプール切換弁装置１が組み立てられると、図２に示したように、スプール切換弁装置１をボディＢＤの空洞部１１０に挿入する。ボディＢＤの空洞部１１０にスプール切換弁装置１を挿入することにより切換ユニット１００が組み立てられる。   When the spool switching valve device 1 is assembled, the spool switching valve device 1 is inserted into the cavity 110 of the body BD as shown in FIG. The switching unit 100 is assembled by inserting the spool switching valve device 1 into the cavity 110 of the body BD.

上記の切換ユニット１００において、第１の導入部１３１から第１の油圧で導入された油は、接続穴１２１、溝部９１、第１入力ポート４１、空洞部２１Ａを順次通って弁体可動部２２に導入される。第２の導入部１３２から第２の油圧で導入された油は、接続穴１２２、第２入力ポート部４２、穴部１６１を順次通って弁体可動部２２に導入される。上記の切換ユニット１００において、第３の導入部１３４から第３の油圧で導入された油は、接続穴１２４、溝部１９１、第１入力ポート１４１、空洞部３１Ａを順次通って弁体可動部３２に導入される。第４の導入部１３５から第４の油圧で導入された油は、接続穴１２５、溝部１９２、第２入力ポート部１４２、貫通部１８２、貫通部１８３、穴部１７１を順次通って弁体可動部３２に導入される。   In the switching unit 100, the oil introduced by the first hydraulic pressure from the first introduction part 131 sequentially passes through the connection hole 121, the groove part 91, the first input port 41, and the cavity part 21A, and the valve body movable part 22 To be introduced. The oil introduced by the second hydraulic pressure from the second introduction part 132 is introduced into the valve body movable part 22 through the connection hole 122, the second input port part 42, and the hole part 161 in order. In the switching unit 100 described above, the oil introduced by the third hydraulic pressure from the third introduction portion 134 sequentially passes through the connection hole 124, the groove portion 191, the first input port 141, and the cavity portion 31 </ b> A, and the valve body movable portion 32. To be introduced. The oil introduced by the fourth hydraulic pressure from the fourth introduction part 135 passes through the connection hole 125, the groove part 192, the second input port part 142, the penetration part 182, the penetration part 183, and the hole part 171 in order to move the valve body. Part 32 is introduced.

例えば、第１入力ポート４１から導入される第１の油圧が第２入力ポート部４２から導入される第２の油圧よりも高い場合には、弁体Ｂ１は、第１の油圧と第２の油圧との圧力差によって−Ｘ側に移動して第２弁座部５３に嵌る。弁体Ｂ１が第２弁座部５３に嵌ると、第２入力ポート部４２と弁体可動部２２との間が閉じられる。従って、第１の導入部１３１から弁体可動部２２に導入された油が出力ポート４３、溝部９３、接続穴１２３を順次通って第１の排出部１３３に排出される油路を選択できる。第２の油圧が第１の油圧よりも高い場合には、弁体Ｂ１は、第１の油圧と第２の油圧との圧力差によって＋Ｘ側に移動して第１弁座部２３に嵌る。弁体Ｂ１が第１弁座部２３に嵌ると、第１入力ポート空洞部２１と弁体可動部２２との間が閉じられる。従って、第２の導入部１３２から弁体可動部２２に導入された油が出力ポート４３、溝部９３、接続穴１２３を順次通って第１の排出部１３３に排出される油路を選択できる。   For example, when the first hydraulic pressure introduced from the first input port 41 is higher than the second hydraulic pressure introduced from the second input port portion 42, the valve body B1 has the first hydraulic pressure and the second hydraulic pressure. Due to the pressure difference from the hydraulic pressure, it moves to the −X side and fits in the second valve seat portion 53. When the valve body B1 is fitted into the second valve seat portion 53, the space between the second input port portion 42 and the valve body movable portion 22 is closed. Therefore, the oil path through which the oil introduced from the first introduction part 131 into the valve body movable part 22 passes through the output port 43, the groove part 93, and the connection hole 123 in order and is discharged to the first discharge part 133 can be selected. When the second hydraulic pressure is higher than the first hydraulic pressure, the valve element B1 moves to the + X side due to the pressure difference between the first hydraulic pressure and the second hydraulic pressure and fits into the first valve seat portion 23. When the valve body B1 is fitted into the first valve seat portion 23, the space between the first input port cavity portion 21 and the valve body movable portion 22 is closed. Therefore, the oil passage through which the oil introduced from the second introduction part 132 into the valve body movable part 22 passes through the output port 43, the groove part 93, and the connection hole 123 in order is discharged to the first discharge part 133 can be selected.

例えば、第１入力ポート１４１から導入される第３の油圧が第２入力ポート部１４２から導入される第４の油圧よりも高い場合には、弁体Ｂ２は、第３の油圧と第４の油圧との圧力差によって＋Ｘ側に移動して第２弁座部５４に嵌る。弁体Ｂ２が第２弁座部５４に嵌ると、第２入力ポート部１４２と弁体可動部３２との間が閉じられる。従って、第３の導入部１３４から弁体可動部３２に導入された油が出力ポート１４３、溝部１９３、接続穴１２６を順次通って第２の排出部１３６に排出される油路を選択できる。第４の油圧が第３の油圧よりも高い場合には、弁体Ｂ２は、第３の油圧と第４の油圧との圧力差によって−Ｘ側に移動して第１弁座部３３に嵌る。弁体Ｂ２が第１弁座部３３に嵌ると、第１入力ポート空洞部３１と弁体可動部３２との間が閉じられる。従って、第４の導入部１３５から弁体可動部３２に導入された油が出力ポート１４３、溝部１９３、接続穴１２６を順次通って第２の排出部１３６に排出される油路を選択できる。   For example, when the third hydraulic pressure introduced from the first input port 141 is higher than the fourth hydraulic pressure introduced from the second input port portion 142, the valve body B2 has the third hydraulic pressure and the fourth hydraulic pressure Due to the pressure difference from the hydraulic pressure, it moves to the + X side and fits in the second valve seat portion 54. When the valve body B2 is fitted into the second valve seat portion 54, the space between the second input port portion 142 and the valve body movable portion 32 is closed. Therefore, the oil path through which the oil introduced from the third introduction part 134 into the valve body movable part 32 passes through the output port 143, the groove part 193, and the connection hole 126 in this order and is discharged to the second discharge part 136 can be selected. When the fourth hydraulic pressure is higher than the third hydraulic pressure, the valve body B2 moves to the −X side due to the pressure difference between the third hydraulic pressure and the fourth hydraulic pressure and fits into the first valve seat portion 33. . When the valve body B2 is fitted into the first valve seat portion 33, the space between the first input port cavity portion 31 and the valve body movable portion 32 is closed. Therefore, the oil passage through which the oil introduced from the fourth introduction part 135 to the valve body movable part 32 passes through the output port 143, the groove part 193, and the connection hole 126 in order and is discharged to the second discharge part 136 can be selected.
