Claims

[Claims for Utility Model Registration] A valve spool that is slidably provided in a valve hole and that controls the hydraulic pressure of a first output hydraulic pressure and a second output hydraulic pressure; 1
a first solenoid on one end side and a second solenoid on the other end side that are pressed in the direction of increasing the first and second output hydraulic pressures by a plunger and a second plunger, and provided at both ends of the valve spool to neutralize the valve spool. In an electromagnetic proportional pressure control valve equipped with a first centering spring on one end side and a second centering spring on the other end side that apply a sliding bias to a position and a set load, both centering springs are provided at the tips of both plungers. a force-receiving portion that comes into contact with the end of the valve spool to receive a biasing force, and a point contact portion that is shaped to be able to make point contact with the end face of the valve spool, and the point contact portion is located at the axial center position of the valve spool. An electromagnetic proportional pressure control valve characterized by being placed in contact with both end faces of a valve spool.
