Abstract
A valve mechanism for a gas spring suspension system that equalizes the gas between positive and negative gas chambers when the pressure in the negative gas chamber exceeds the pressure in the positive gas chamber. The suspension system includes a tube, a piston assembly slidably displaceable along the tube and a valve mechanism. The piston assembly separates the tube into the positive gas chamber and the negative gas chamber. The valve mechanism is configured to permit gas flow between the positive and negative gas chambers when the gas pressure in the negative gas chamber exceeds the gas pressure in the positive gas chamber.
