Abstract

PURPOSE:To effectively utilize air in a tank and decrease a rising time of car height, by such constitution that a solenoid valve, opened by a rising signal, is interposed between an air compressor and compressed air tank, and the air in the tank is fed to a suspension device through the compressor. CONSTITUTION:A solenoid valve 17 and feed air valve 7 are opened by a car height rising signal, and air in a tank 4 is sucked by a suction valve 18 of a compressor 1, compressed and delivered from a delivery valve 19. This compressed air is fed to a suspension main unit 9 and air chamber 10 through passages 21, 22, dryer 2, check valve 23 and feed air valve 7. Accordingly, the air in the tank 4, even if its pressure is lower than pressure in an air chamber 10, can be surely pressurized by the compressor 1. In this way, the air in the tank can be effectively utilized approximately to the atmospheric pressure, further pressure in the air chamber 10 can be earlier increased to decrease a car height rising time.
