ブサスペンシヨンの油圧回路。 An active suspension mechanism that has a control valve that controls the supply and discharge of hydraulic oil to a single-acting cylinder arranged in parallel with a suspension spring, and a shaft valve for maintaining vehicle height that shuts off a supply line and a return line to the control valve. A solenoid valve for vehicle height adjustment which is opened by energization in the return pipe from the control valve, with a bypass passage for the shutter valve provided in the passage and a throttle provided in the passage or in the return pipe downstream from the passage. and the shut valve is configured to open and close based on the pressure difference between the pressure in the supply line and the pressure in the return line upstream of the solenoid valve. circuit.
