徴とする電磁比例圧力制御弁。 A reaction piston is slidably inserted into a hole formed in the axial direction of both ends of the spool housed in the valve body, one end of which is open to the spool end, and the other end of which is communicated with the actuator port. A push rod driven by a solenoid is positioned at both ends of the spool while in contact with the reaction piston, and a centering spring is disposed at both ends of the spool via a spring retainer, and the solenoid is energized to cause the push rod to spool. In the electromagnetic proportional pressure control valve configured to switch the spool by pressing , small diameter parts are formed at both ends of the spool, the spring retainer is loosely fitted into the small diameter parts, and the spool axis of the spring retainer is aligned with the spool axis of the spring retainer. The electromagnetic proportional device is characterized in that a tapered portion for regulating displacement in orthogonal directions is provided on at least one of the small diameter portion and the inner diameter portion of the spring retainer, and the outer diameter portion of the valve body and the spring retainer. Pressure control valve.
