Abstract
A vehicle leveling system for varying the attitude between the sprung and unsprung portions of a vehicle and including at least one leveling strut comprising an elongated tubular pressure cylinder, a valved piston reciprocally disposed within the cylinder and connected to a piston rod extending axially from one end of the cylinder, a rod guide and seal assembly disposed within one end of the cylinder for guiding the piston rod for reciprocal movement, a floating piston disposed within the cylinder between the piston and the end of the cylinder opposite that from which the piston rod extends, a quantity of super-atmospheric gas located within the cylinder between the floating piston and the adjacent end of the cylinder, a quantity of damping fluid located within the cylinder on the opposite side of the floating piston and cooperable with the valved piston to damp reciprocal movement of the piston rod, a resilient tubular diaphragm element defining a variable volume chamber surrounding the pressure cylinder, and means for selectively communicating a source of compressed gas to and from the chamber to effect expansion and contraction thereof.
