グの流量制御装置。The hydraulic oil from the hydraulic pump is applied to the switching force of the handle.
In a power steering system that sends hydraulic fluid to the power steering actuator depending on the direction, a spool valve guides hydraulic oil from the pump port to the operating port via an orifice hole, and opens and closes the suction port in response to the back and forth pressure of the orifice hole. The spool valve is provided with a protruding drooping pin that is inserted into the orifice hole to change the effective area, and an electromagnetic solenoid that operates based on the output of the vehicle speed sensor is installed to prevent the orifice from closing in the medium to high vehicle speed range. A flow control device for power steering, characterized in that the drooping pin is configured to be displaced by an electromagnetic solenoid in order to relatively reduce the effective area of the hole.
