量制御装置。A variable orifice that senses vehicle speed and narrows the flow path at high speeds is installed 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. A flow control valve that releases a portion of the hydraulic oil to the reservoir in response to the differential pressure across the upper and lower parts is interposed, and a spool that opens and closes a bypass port that releases a portion of the hydraulic oil to the reservoir. ,
A power steering system characterized by comprising a drooping pin that works in conjunction with the spool to narrow down the passage area to the supply port, and a means for guiding hydraulic pressure to both ends of the spool so that the spool responds to the differential pressure across the throttle. flow control device.
