Abstract
A hydropneumatic suspension system for a tractor-scraper unit or the like has a hydraulic cushioning jack connected between the vehicle body and a pivotal suspension arm supporting each wheel. The cushioning jack with an associated accumulator is selectively connected to pump pressure or drain via a height control valve for raising or lowering the vehicle body relative to the wheels. For actuation of the height control valve there is operatively connected between the valve and the suspension arm a dual cylinder mechanism comprising two unitized, axially aligned air cylinders actuated from a manual selector valve. When the manual selector valve is in neutral, all the chambers of the dual cylinder mechanism are opened to atmosphere so that the height control valve is prevented from accidental actuation as the vehicle travels over rough terrain.
