取装置用流量制御装置。 A fixed throttle and a throttle passage are provided in the fluid passage leading from the supply passage leading to the pump to the delivery hole, and the flow rate adjustment spool is slid by the pressure of the fluid before and after the throttle passage, and the excess flow is directed to the pump. In the power steering device flow control device, the flow control device controls the opening area of the throttle passage by controlling the opening area of the throttle passage by sliding a control spool by the pressure of the fluid before and after the fixed throttle. A flow control device for a power steering device, characterized in that a throttle forming member is provided slidably in the same direction as the sliding direction of the control spool, and the throttle passage is formed in the throttle forming member.
