制御装置。A bypass that allows a part of the hydraulic oil to escape to a reservoir through a flow control valve that is interposed between a hydraulic pump that is driven in synchronization with engine rotation and a power steering actuator that is operated by receiving this hydraulic oil supply. Consists of a spool that opens and closes the port, a drooping pin that works with this spool to narrow down the passage area to the supply port, and a pilot passage that guides hydraulic pressure to both ends of the spool so that the spool responds to the differential pressure across the throttle. The power steering flow control device is further characterized in that a pressure bypass valve that senses vehicle speed and releases pilot pressure in a high speed range is interposed in the drain circuit leading from the pilot passage to the reservoir.
