Abstract: Self-pumping hydropneumatic shock strut with internal level regulation for motor vehicles with a work cylinder which is filled with oil and acted upon by pressure by at least one gas cushion arranged in a high-pressure chamber which acts as a spring. The work cylinder is divided into two work spaces by a work piston carried by a hollow piston rod. The work piston has a piston pump which is driven by the spring movements and delivers oil from a low-pressure chamber in the work space connected with the high-pressure chamber. The pump cylinder of the piston pump is formed by the hollow piston rod. A hollow pump rod which is fastened to the work cylinder and carries a suction valve at its front end penetrates into the piston rod and the bore of the hollow pump rod is connected with the low-pressure chamber.
