テアリング用流量制御装置。 A hydraulic circuit is connected to a power cylinder that assists the steering operation of the steering gear, and oil from a hydraulic pump in the hydraulic circuit is received by a discharge amount control valve, and the discharge amount of the oil is maintained within a predetermined value. In the power steering oil amount control device configured to discharge oil to the power cylinder side, a flow rate control valve is interposed between the discharge amount control valve and the power cylinder, and the flow rate control valve is configured to discharge oil to the power cylinder side. A flow control device for power steering, characterized in that the amount of oil discharged is adjusted to increase or decrease according to the differential pressure between the output hydraulic pressure applied to the power cylinder side and the suction port pressure of the hydraulic pump or the discharge pressure of the discharge amount control valve. .
