圧回路。[Claims for Utility Model Registration] An active suspension that achieves posture control by controlling the internal pressure of a single-acting cylinder arranged in parallel with a suspension spring, wherein the hydraulic oil supply and discharge control valve for controlling the internal pressure is connected to hydraulic oil. In a control system configured to be unaffected by pressure in the return pipe of a vehicle, a return valve between the control valve and a vehicle height maintenance shaft valve that connects the pair of left and right control valves to the hydraulic oil source side of the vehicle is provided. A hydraulic circuit for an active suspension, characterized in that a check valve that allows only the flow of hydraulic oil from a control valve to a shaft valve, and a throttle pipe arranged in parallel with the check valve are inserted in a pipe.

圧回路。 This is an active suspension that maintains the vehicle height by controlling the internal pressure of a single-acting cylinder arranged in parallel with a suspension spring, and the hydraulic oil supply/discharge control valve for controlling the internal pressure controls the pressure of the hydraulic oil return line. In a control system having a configuration that is not affected, a control valve is connected to a return pipe between the control valve and a vehicle height maintenance shaft valve that connects the left and right control valves to the hydraulic oil source side of the vehicle. A hydraulic circuit for an active suspension characterized by inserting a check valve that allows only the flow of hydraulic oil toward the shaft valve and a throttle pipe line installed in parallel with the check valve.
