ことを特徴とする電磁比例圧力制御弁。 The electromagnetic force generated by the electromagnetic proportional solenoid is transmitted from the plunger to one end surface of the spool inserted into the spool hole of the housing through the pressing member, and secondary pressure is supplied to the other end surface, thereby increasing the valve opening pressure due to the electromagnetic force. In the electromagnetic proportional pressure control valve, the position of the spool is controlled according to the valve closing pressure caused by the secondary pressure, and the primary pressure is reduced to obtain the predetermined secondary pressure. A secondary port is provided on the end surface of the hole opposite to the other end surface of the spool.
forming a primary port and a tank port sequentially communicating with the spool hole from the next port side in the direction of the plunger, one end opening in the spool opposite to the secondary port on the other end surface of the spool;
The other end opens at a predetermined position on the outer peripheral surface and forms a passage communicating with the primary port or the tank port depending on the spool position, and between the other end surface of the spool and the secondary port of the housing. A spring biasing the spool in the valve closing direction is interposed, and valve opening pressure due to the electromagnetic force applied to the one end surface of the spool, closing due to the secondary pressure applied to the other end surface and the spring. An electromagnetic proportional pressure control valve, characterized in that the position of the spool is controlled depending on the valve pressure.
