に記載の圧力制御弁。[Claims for Utility Model Registration] (1) By supplying control pressure to one spool end side of a three-way spool valve and supplying pilot pressure to the other spool end side, the control pressure can be controlled according to the pilot pressure. In a pressure control valve that generates control pressure, the pilot pressure is formed by a pressure reducing valve that generates a pressure proportional to the thrust of a proportional solenoid and shuts off the input flow rate when the pilot pressure does not fluctuate. A pressure control valve featuring: (2) The pressure control valve according to claim 1, wherein the spool is selected such that the area on the pilot pressure side is several times larger than the area on the control pressure side. (3) The pressure control valve according to claim 1 or 2, wherein a damping force generating section is formed by introducing drain pressure into one end of the spool through a throttle. (4) The pressure control valve according to any one of claims 1 to 3, wherein the pressure reducing valve uses the control pressure as its supply pressure. (5) The pressure control valve according to any one of claims 1 to 4, wherein the pilot pressure of the pressure reducing valve is supplied to the pilot pressure side of the spool through a throttle.
