ABSTRACT:
A leveling system for motor vehicles including leveling dampers at front and rear road wheels, a solenoid-operated selector valve assembly connected between an air compressor and the leveling dampers, and a central processing unit programmed so as to be responsive to command signals from level sensors or a manual override control switch for controlling the selector valve assembly to direct pressurized air through selected pneumatic circuits to the level dampers, thus adjusting the riding height of the vehicle frame, even in opposite directions, at the front and rear road wheels. A drier is disposed in the pneumatic circuit downstream of the air compressor to remove water from the pressurized air for preventing the leveling system from malfunctioning due to the presence of water in the system.
