Abstract
In a gas suspension system for controlling a body attitude of a vehicle, a controller drives a compressor and control valves to supply compressed air to a high pressure reserve tank. After enough air is supplied to the high pressure reserve tank, the compressor is stopped and the control valves are shut, whereby high pressure air remains at the delivery port of the compressor. Then a specially provided connection control valve is opened for a predetermined period in order to put the delivery port of the compressor in communication with a low pressure reserve tank. The pressure at the delivery port thus can be decreased, resulting in less torque needed to start the compressor.
