The housing 2 has a shape in which a front end side cylinder portion is fitted into an attachment hole formed as a cylindrical passage inside the passage forming member on the automatic transmission or the automatic transmission side, and extends in the axial direction of the attachment hole. . The passage forming member is formed with an oil inflow passage through which regulated oil flows. The oil inflow passage communicates with the inflow valve port 11 that is formed inside the housing 2 and is in a valve open state. The housing 2 has a shaft holding portion 24 located on the opposite side of the axial center direction from the distal end side tubular portion fitted in the mounting hole. The shaft holding portion 24 holds the shaft 4 so as to be displaceable in the axial direction, and is assembled to the electromagnetic solenoid portion 3 that is externally fitted.

  A filter chamber 21 is provided in the housing 2 at a position close to the tip. The filter chamber 21 is a chamber into which oil from the automatic transmission side first flows into the solenoid valve 1. The filter chamber 21 is provided with a filter member 6 that covers the entire cross section of the passage and filters the oil of the working fluid. The housing 2 is provided with a discharge valve port 13 that faces the oil inflow valve port 11 on the downstream side in the axial direction, and further intersects the axial direction between the inflow valve port 11 and the discharge valve port 13. Thus, an outflow passage 12 extending laterally is provided. The outflow passage 12 is connected to an oil outflow passage formed in the passage forming member and leading to the transmission valve.

Moreover, you may form the filter member 6 by adhere | attaching, welding, etc. the net | network part and frame part which are separate members.

  The second seat portion 23 is a peripheral portion that forms the discharge valve port 13 inside the housing 2. The second seat portion 23 constitutes a downstream end portion of the valve chamber 22 formed inside the housing 2. The valve chamber 22 is a chamber that includes a space located between the inlet valve port 11 and the outlet valve port 13 and communicates with the inlet valve port 11, the outlet valve port 13, and the outlet passage 12. A ball valve 5 is accommodated in the valve chamber 22. The ball valve 5 exhibits a valve function of selectively opening and closing the inflow valve port 11 or the discharge valve port 13 by the operation of the electromagnetic valve 1.

  The valve chamber 22 is provided with a cylindrical ball guide portion 52. The ball guide portion 52 is installed on the downstream side of the first seat portion 51. The ball guide portion 52 holds the ball valve 5 disposed on the inner side coaxially with the inflow valve port 11 and the discharge valve port 13. The cylindrical inner wall surface of the ball guide portion 52 guides the reciprocation of the ball valve 5 in the axial direction.

  The ball guide portion 52 is formed with a communication port communicating with the inflow valve port 11 and the discharge valve port 13. The communication port is an opening that passes through the cylindrical wall of the ball guide portion 52. The ball guide portion 52 includes a plurality of communication ports, and the plurality of communication ports are arranged at equal intervals in the circumferential direction, for example. According to this configuration, even if the ball guide portion 52 rotates in the valve chamber 22, the oil can be discharged to the outflow passage 12 side with a small flow path distance.

  A first seat portion 51 provided with the inflow valve port 11 is provided in the range from the filter chamber 21 to the valve chamber 22 upstream of the second seat portion 23. The first seat portion 51 is provided with a through hole that constitutes the inflow valve port 11 in the center portion. As for the 1st sheet | seat part 51, the end surface located in the downstream is in contact with the ball guide part 52. FIG. The first seat portion 51 is installed coaxially with the discharge valve port 13, the ball valve 5 and the inflow valve port 11. When the ball valve 5 moves upstream and contacts the first seat portion 51, the inflow valve port 11 is closed, and the first seat portion 51 constitutes the upstream valve seat portion. When the ball valve 5 moves downstream and contacts the second seat portion 23, the discharge valve port 13 is closed, and the second seat portion 23 constitutes a downstream valve seat portion.

  In the solenoid valve 1, oil having a higher pressure than the fuel vapor flows as a working fluid. In order to suppress this oil leakage, the solenoid valve 1 includes an O-ring seal that is attached to the outer periphery of the front end side of the housing. The O-ring seal is an annular seal member that is fitted into a groove formed on the inner periphery of the passage forming member.

  The ball valve 5 is disposed on the rear end side of the valve chamber 22, and is displaced in the axial direction by the shaft 4 that operates in the axial direction by the electromagnetic solenoid portion 3, and the first seat portion 51 around the inflow valve port 11. And the second seat portion 23 around the discharge valve port 13 are selectively seated. When the ball valve 5 is seated on the wall around the discharge valve port 13, communication between the external discharge passage 15 and the oil inflow passage communicating with the outside is blocked, and communication between the oil inflow passage and the oil outflow passage is allowed. . As a result, the oil flowing through the oil inflow passage passes through the inflow valve port 11, the communication port of the ball guide portion 52, and the outflow passage 12 and flows down to the oil outflow passage.

  When the ball valve 5 is seated on the first seat portion 51, the communication between the oil inflow passage and the oil outflow passage is blocked, and the communication between the oil outflow passage and the external discharge passage 15 is allowed. As a result, oil from the oil outflow passage passes through the outflow passage 12, the communication port of the ball guide portion 52, and the discharge valve port 13, and is discharged from the external discharge passage 15 to the outside.

  The electromagnetic solenoid unit 3 disposed on the rear end side of the housing 2 includes a yoke 31, a bobbin 34, a coil 32, a mover 33, a shaft 4, a spring 45, a connector 8, and the like. The bobbin 34 is formed in a substantially cylindrical shape by a resin material and is provided inside the yoke 31. The coil 32 is wound around the outer peripheral surface of the bobbin 34. The bobbin 34 is fixed to the housing 2 by being press-fitted into a plate 35 fixed to the housing 2 on the bracket 7 or the valve body side. The yoke 31 is made of a magnetic material. The yoke 31 is provided coaxially with the bobbin 34 so as to support the inner peripheral side of the bobbin 34 and cover the outer peripheral side of the coil 32. The bobbin 34 is provided coaxially with the housing 2 while being housed inside a yoke 31 that slidably supports the shaft 4. The yoke 31, the mover 33, the shaft 4, and the like are provided coaxially with the housing 2 as with the bobbin 34. An end plate 36 is fixed to the bottom of the yoke 31.

  The mover 33 is formed of a magnetic material in a cylindrical shape. The mover 33 is supported by the yoke 31 so as to be capable of reciprocating in the axial direction. In the electromagnetic solenoid unit 3, a magnetic circuit is formed by the mover 33 and the yoke 31.

  A large diameter portion 44 of the shaft 4 is coaxially fixed to an end portion of the movable element 33 on the housing side. The shaft 4 and the mover 33 are integrated and can reciprocate in the axial direction. The shaft 4 is slidably fitted into the shaft holding portion 24 through a tip portion 41 having a small diameter concentrically positioned at the discharge valve port 13, a tapered portion 42 positioned at the discharge passage 14, and a stepped portion 43. The large-diameter portion 44 is integrally provided. The discharge passage 14 communicates with an external discharge passage 15 formed on the rear end side of the housing 2. The external discharge passage 15 is a passage provided in the housing 2 on the front end side of the shaft holding portion 24 so as to extend in a direction orthogonal to the discharge passage 14.

  A spring 45 that is an example of a spring member is interposed between the stepped portion 43 and the discharge valve port 13. The spring 45 always applies a biasing force that pushes the shaft 4 toward the movable element 33. Further, the ball valve 5 disposed in the valve chamber 22 is pushed toward the mover 33 by the action of hydraulic pressure. As a result, when the electromagnetic solenoid unit 3 is not energized, the shaft 4 is urged by the spring force of the spring 45 and is pushed toward the mover 33 via the ball valve 5 by the action of hydraulic pressure. Opens the inlet valve port 11 and closes the outlet valve port 13. The ball valve 5 is a valve body that can open and close a passage formed inside the housing 2.

  The connector 8 is formed with the outer skin of the coil 32 and has a shape extending so as to protrude outward from the yoke 31. The connector 8 is made of resin. The connector 8 is a resin molded product having a terminal 8a for energizing the coil 32, and the terminal 8a protrudes from the inside to the outside. The terminal 8 a is an energization terminal that is electrically connected to the coil 32. The connector 8 is connected to a power supply side connector for supplying power from the power supply unit and the current control device. When the connector 8 and the power supply side connector are connected and the terminal 8a is electrically connected to a current control device or the like, the electromagnetic solenoid unit 3 can control the current supplied to the coil 32.

  The bracket 7 is formed to include an annular support portion 70 and a protruding portion that is a portion protruding outward from the annular support portion 70. The bracket 7 is attached to the vehicle installation side member 100 on which the electromagnetic valve 1 is installed with an attachment portion 71 located on one side. The bracket 7 fixes and supports the housing 2 with an annular support portion 70 located on the other side. The annular support portion 70 is coupled to the outer peripheral portion of the housing 2 on the inner peripheral side, and is coupled to the yoke 31 on the outer peripheral side. The annular support part 70 is provided with an opening penetrating in the center. The shaft holding portion 24 of the housing 2 is fitted in the opening, and the annular support portion 70 fixedly supports the housing 2 at the shaft holding portion 24. Therefore, the bracket 7 has a function of integrally supporting the electromagnetic solenoid portion 3 and the housing 2 by fixing and supporting the housing 2 and being coupled to the yoke 31.

  The protruding portion has a mounting portion 71 on the distal end side and a connecting portion 72 that protrudes from the annular support portion 70 on the base side. The attachment portion 71 includes an attachment hole 71 a through which a fixture for fixing the bracket 7 to the vehicle installation side member 100 can be inserted. When the bracket 7 is fixed to the vehicle installation side member 100, the fixing hole is inserted together with the attachment hole 100 a in a state where the attachment hole 71 a is aligned with the attachment hole 100 a provided in the vehicle installation side member 100. The fixture can be constituted by, for example, a bolt and nut, and the bracket 7 and the vehicle installation side member 100 are integrally fixed via the fixture.

  The connecting portion 72 is a portion that connects the mounting portion 71 and the annular support portion 70, and extends in a direction that intersects the direction in which the connector 8 protrudes outward with respect to the housing 2, as shown in FIG. 1. The bracket 7 includes a rotational displacement restricting portion that restricts the displacement of the connector 8 in the circumferential direction adjacent to or in contact with the connector 8 in the circumferential direction of the housing 2. The rotational displacement restricting portion is a portion that can come into contact with the bracket 7 when the connector 8 is rotationally displaced in the circumferential direction. The rotational displacement restricting portion can be set on the side wall 711 that forms the attachment portion 71. Further, the rotational displacement restricting portion can be set at a part of the side wall forming the protruding portion.

  The connector 8 is formed integrally with the bobbin 34 and further constitutes a part of the electromagnetic solenoid portion 3 outside the coil 32. Accordingly, the connector 8 forms a part of the outline of the electromagnetic valve 1. As shown in FIG. 1, the connector 8 is adjacent to the attachment portion 71 in the circumferential direction. The connector 8 further has a terminal support portion 82 adjacent to the protruding portion of the bracket 7 in the radial direction intersecting the axial direction and the circumferential direction of the housing 2. The terminal support portion 82 has a terminal 8a integrally therein. As shown in FIG. 2, the terminal support portion 82 has a shape that protrudes to the upstream side of the electromagnetic valve 1 and the valve body side from the portion of the connector 8 that houses the connection portion between the terminal 8 a and the coil 32.

  The terminal support portion 82 corresponds to a regulated portion adjacent to or in contact with the rotational displacement regulating portion in the bracket 7. The side wall located on the housing 2 side in the terminal support portion 82 has a shape along the guide side wall 721 of the connecting portion 72, and forms a surface substantially along the circumferential direction.

  Further, as shown in FIGS. 1 and 2, the connector 8 is installed so as to move back and forth with the protruding portion of the bracket 7 in the axial direction of the housing 2. A portion of the connector 8 located on the housing 2 side of the terminal support portion 82 overlaps the connecting portion 72 in the axial direction.

  As shown in FIG. 1, the bracket 7 has a coupling portion 311 that is coupled to the yoke 31 in the annular support portion 70 except for a portion where the projecting portion projects. The coupling portion 311 is configured to be interrupted between the end portion 311a and the end portion 311b. A space between the end 311 a and the end 311 b corresponds to a portion where the protruding portion protrudes, and corresponds to an opening where the yoke 31 opens at a joint portion with the bracket 7. The connector 8 is installed so as to protrude outward from the opening together with the protruding portion of the bracket 7. The coupling portion 311 is configured by caulking so that a portion of the yoke 31 overlapping the annular support portion 70 of the bracket 7 is brought into close contact with the annular support portion 70.

  The solenoid valve 1 can be manufactured through a first step, a second step, and a third step, which will be described below. The first step is a step of assembling the housing 2 and the bracket 7 together by press-fitting the annular support portion 70 of the bracket 7 into the outer peripheral portion of the housing 2. The second step is a step of assembling the connector 8, the bobbin 34 and the coil 32 by press-fitting the housing 2 and the bracket 7. In the third step, the yoke 31 is covered from the mover 33 side in a state where the mover 33 is installed on the integrated body that has undergone the second step. Further, in the third step, the yoke 31 is crimped on the outer peripheral side of the annular support portion 70 in a state where the coil 32, the mover 33 and the connector 8 are supported from the outside by the yoke 31, and the yoke 31 is attached to the bracket 7. It is the process of fixing.

  Next, the operation of the electromagnetic valve 1 will be described. In a state where the coil 32 of the electromagnetic solenoid unit 3 is not energized, the shaft 4 is urged away from the ball valve 5 by the spring force of the spring 45, and the ball valve 5 is pushed to the rear end side by hydraulic pressure. The valve 5 closes the discharge valve port 13. In this state, the communication between the oil inflow passage and the oil outflow passage is permitted, and the oil from the oil inflow passage passes through the inflow valve port 11, the communication port of the ball guide portion 52, and the outflow passage 12, and the oil outflow passage. Spill to

  When the coil 32 is energized in this state, a magnetic field is generated in the magnetic circuit formed by the yoke 31 and the mover 33, and the mover 33 is attracted in the axial direction toward the distal end side of the housing 2 by electromagnetic force. This suction force moves against the urging force of the spring 45 and the oil pressure, and moves to the tip side to move the shaft 4.

  As a result, the ball valve 5 moves to the distal end side and closes the inflow valve port 11. Thereby, the communication between the oil outflow passage and the external discharge passage 15 is allowed, and the oil from the oil outflow passage passes through the outflow passage 12, the communication port of the ball guide portion 52, the discharge valve port 13, and the external discharge passage. 15 is discharged to the outside. In this way, by turning ON / OFF the value of the current supplied to the coil 32, the control fluid pressure in the oil outflow passage can be controlled ON / OFF. Thereby, the pressure, flow rate, etc. of the control liquid used for control of the controlled object can be controlled.

  Next, the effect which the electromagnetic valve 1 of 1st Embodiment brings is demonstrated. The electromagnetic valve 1 includes a housing 2 that accommodates a valve body, and a yoke 8 that integrally supports a connector 8, a coil 32, and a part of the connector 8, and generates an electromagnetic force for driving the valve body. And a solenoid unit 3. The electromagnetic valve 1 further includes a bracket 7 that fixes and supports the housing 2, is coupled to the yoke 31, is provided integrally with the electromagnetic solenoid unit 3, and is attached to the vehicle installation side member 100. The bracket 7 includes a rotational displacement restricting portion that restricts the displacement of the connector 8 in the circumferential direction adjacent to or in contact with the connector 8 in the circumferential direction of the housing 2.

  According to the electromagnetic valve 1, the bracket 7 and the connector 8 can be supported so as not to move with respect to the yoke 31. Further, the bracket 7 can restrict the movement of the connector 8 in the circumferential direction by the rotation displacement restricting portion. When the solenoid valve 1 is fixed to the vehicle installation side member 100, the bracket 7 fixed to the vehicle installation side member 100 restricts the circumferential displacement of the connector 8, so the connector 8 is fixed to the bracket 7 via the yoke 31. In addition, the connector 8 can be fixed in the circumferential direction by the bracket 7. The electromagnetic valve 1 can properly position the connector 8 with respect to the member on the vehicle installation side by the configuration having the electromagnetic valve 1 alone without requiring any ingenuity on the member on the vehicle installation side, and can be connected to the power source. The installation work of the solenoid valve 1 including it can be performed appropriately and smoothly. According to the electromagnetic valve 1, it is possible to improve the positional accuracy of the connector 8 when the vehicle is assembled.

  The bracket 7 has an annular support portion 70 that is coupled to the outer peripheral portion of the housing 2 on the inner peripheral side and is coupled to the yoke 31 on the outer peripheral side, and an attachment portion 71 that is attached to the vehicle installation side member 100. And a projecting portion extending so as to project outward. The rotational displacement restricting portion is a side wall that forms a protruding portion. According to this configuration, the bracket 7 prevents the connector 8 from moving in the circumferential direction by the attachment portion 71 or the connecting portion 72 that connects the attachment portion 71 and the annular support portion 70. Thus, the bracket 7 fixed to the vehicle installation side member 100 can regulate the circumferential displacement of the connector 8 over a wide range of the portion protruding outward from the annular support portion 70 including the mounting portion 71. Accordingly, since the rotational displacement restricting portion can be set according to the outer shape of the bracket 7, the portion of the bracket where the rotational displacement restricting portion is set according to the size and the outer shape of the connector 8 to be used can be freely set. The solenoid valve 1 having a large degree can be provided.

  The attachment portion 71 is provided with an attachment hole 71a through which a fixture for fixing the bracket 7 to the vehicle installation side member 100 can be inserted. The rotational displacement restricting portion is a side wall 711 that forms the attaching portion 71. According to this configuration, the bracket 7 can prevent the connector 8 from moving in the circumferential direction by the mounting portion 71. In this way, the mounting portion 71 that is firmly fixed to the vehicle installation side member 100 is utilized to regulate the circumferential displacement of the connector 8, so that even if a strong external force is applied to the connector 8, it is easily displaced. It is possible to provide a difficult rotational displacement restricting portion.

  The connector 8 is adjacent to the mounting portion 71 in the circumferential direction, and is in a positional relationship back and forth with the protruding portion in the axial direction intersecting the circumferential direction. According to this configuration, when the vehicle is mounted, the rotational displacement of the connector 8 is restricted by the mounting portion 71, and the connector 7 is projected by the protruding portion of the bracket 7 even when an external force is applied to the connector 8 in the axial direction of the bracket 7. 8 can be supported. Thereby, the bending of the connector 8 in the axial direction can be reduced, and the electromagnetic valve 1 that suppresses damage to the power supply connection portion can be provided.

  The connector 8 has a regulated portion adjacent to the mounting portion 71 in the circumferential direction and adjacent to the protruding portion in the radial direction intersecting the axial direction and the circumferential direction. The side wall located on the housing 2 side in the regulated portion has a shape along the guide side wall 721 of the protruding portion. According to this configuration, the regulated portion of the connector 8 and the guide side wall 721 of the protruding portion are shaped so as to follow each other. As a result, the bracket 7 can provide the electromagnetic valve 1 that can be smoothly installed so that the connector 8 has a proper positional relationship with the bracket 7 while restricting the rotational displacement of the connector 8. The bracket 7 that contributes to manufacturing the electromagnetic valve 1 that can reliably achieve the object disclosed in this specification can be provided.

  The bracket 7 has a coupling portion that is coupled to the yoke 31 in the annular support portion 70 except for a portion where the projecting portion projects. The connector 8 protrudes outward from a portion overlapping the portion excluding the coupling portion in the annular support portion 70 in the axial direction intersecting the circumferential direction. According to this configuration, the connector 8 and the protruding portion of the bracket 7 are configured to protrude outward from a portion excluding the coupling portion between the annular support portion 70 and the yoke 31. Thereby, the electromagnetic valve 1 which can set appropriately the positional relationship of the connector 8 and the bracket 7 at the time of the assembly of the electromagnetic valve 1 by the site | part which does not form the said connection part can be provided. Therefore, it can contribute to manufacture of the solenoid valve 1 that can reliably achieve the object disclosed in the specification.
