磁比例制御弁。 It is inserted into a housing in which a pump port and an actuator port are formed, and a spool hole formed in the housing, and is biased in the axial direction by a return spring, and by movement in the biasing direction, the pump port and actuator port are connected. A spool that interrupts the flow and connects the pump port and actuator port by moving in the opposite direction to the biasing direction, a casing fixed to the end of the housing on the side opposite to the return spring, and a solenoid provided within the casing. In an electromagnetic proportional control valve equipped with an armature that slides when energized and moves the spool against the biasing force of a return spring, a cylindrical hole is formed in the end of the housing on the side opposite to the return spring,
An electromagnetic proportional control valve characterized in that a ring-shaped collar is fitted into the cylindrical hole, the outer diameter side of the diaphragm is supported on the inner periphery of the end of the ring-shaped collar, and an annular filter is attached to the outer periphery.
