PURPOSE:To adjust height of a car without causing the generation of an aerodynamic loss and uneven wear of a tire, by applying operation in the pressure side of a hydraulic shock absorber as action of a pump. CONSTITUTION:If the height of a car is decreased, only a solenoid valve SV1 is opened while solenoid valves SV2, SV3 are closed. Under this condition, if the car is moved bouncing and pitching to operate a hydraulic shock absorber 1 to a pressure side, working fluid flows in a route such as oil chamber A valve SV1 check valve CV1 pressure chamber C of a car height adjusting cylinder 4, on the othr hand, working fluid is compensated to an oil chamber B by a route such as tank 2 check valve CV2 oil chamber B. In this way, at each time the absorber 1 is operated on the pressure side, the working fluid is supplied to the chamber C of the cylinder 4 to restore the height of the car. |
