ABSTRACT:
A hydropneumatic spring in which a casing filled with fluid under pressure is selectively movable with respect to a piston contained within the casing and mounted on a stationary hollow support rod. The piston divides the casing into an upper and lower chamber. When the fluid path is unlocked or opened and the casing is subjected to axial pressure, fluid passes from one chamber to the other through the hollow support rod and axially through the piston.
