Abstract
Behind the buffer spring, and between the piston and its cylinder is a gap for through-flow of a damping fluid. The ring space of the cylinder (7) on the connecting rod side is connected to a compensation chamber (10) which contains a gas cushion (22). The piston (5) and the cylinder (7) are so formed that the gap (14) either remains the same size or dimishes when the fluid pressure in the cylinder increases. On the front end of the piston and through a recess is a ring-shaped wall which can be widened elastically by fluid pressure. The compensation chamber is formed ring-shape around the cylinder (7).
