Abstract

A vehicle leveling system including a compressor, a leveler unit for lifting a vehicle body by compressed air from the compressor and an air dryer provided between filter casing filled with a filter element having moisture depositing function and a desiccant compartment filled with desiccant material. The filter casing is located on the side of the compressor while the desiccant compartment is located on the side of the leveler unit such that the filter casing has an area of air flow passage smaller than that of the desiccant compartment. The leveling system further includes a change-over valve which is connected to the air dryer on the side of the compressor to communicate the leveler unit selectively with either the compressor or atmosphere.
