る圧力制御弁。 A solenoid that generates a force proportional to the current, a spool whose output pressure is guided to one end as feedback pressure, and whose position is determined by the balance between this feedback pressure and the force of the solenoid, and a spool that is positioned according to the sliding position of this spool. In a proportional control type pressure control valve comprising a supply port and a drain port whose communication with an output port is controlled by a pressure control valve, a large diameter portion is provided at one end of the spool to provide a feedback pressure chamber and a flow rate compensation counter thereto. The upstream pressure of an orifice provided in the output port or equivalent flow path resistance is guided to the flow compensation pressure chamber, and the downstream pressure is guided to the feedback pressure chamber. A pressure control valve characterized by:
