路。 A hydraulic circuit for a vehicle, wherein an accumulator is provided in a passage connecting a hydraulic actuator and a hydraulic pump, and hydraulic oil flowing back from the hydraulic actuator to a reservoir is sucked into the hydraulic pump. A valve body is provided in the passage between the accumulator and the accumulator, and the valve body is operated in response to the pressure accumulated in the accumulator and the control force according to the vehicle speed, and the pressing force of the spring, so that the pressure accumulated in the accumulator can be varied according to the vehicle speed. A hydraulic circuit for a vehicle, characterized in that it is equipped with a regulating valve for controlling the vehicle.
