Abstract

PURPOSE:To feed and discharge air through a single reservoir tank and compressors, by providing the first and the second valves in the feed and discharge passages of a pneumatic suspension. CONSTITUTION:To move up a pneumatic suspension 3, the first valve 5 is opened by a move-up signal and a compressor 4 is driven. At that time, the second valve 9 is closed and another compressor 10 is not driven. As a result, air in a reservoir tank 1 is supplied to the suspension 3 through a passage 2 to heighten pressure in the suspension. To move down the suspension, the second valve 9 is opened and the compressor 10 is driven. At that time, the first valve 5 is closed and the other compressor 4 is not driven. As a result, air in the suspension 3 is discharged into the tank 1 through another passage 8 to reduce pressure in the suspension 3.
