PROBLEM TO BE SOLVED: To make the responsiveness of a power cylinder to the change of flow rapid, make the bidirectional characteristic of the power cylinder for the lateral action of a steering wheel equal and feed or maintain the appropriate quantity of flow to the power cylinder according to a variable vehicle speed and a steering angle speed. SOLUTION: In a flow control valve 100 disposed between a power cylinder 10 and a directional control valve 70, oil in a compressed chamber 11 or 13 of the power cylinder 10 is made by-pass to a tank 50 through the bidirectional orifice of a spool 130 adjusted in opening according to a vehicle speed and a steering angle speed. |
