Abstract (en)
[origin: WO9849451A1] The invention relates to a shock-proof hydraulic cylinder comprising a casing (1) inside which a piston is axially driven on a piston rod (10), and possibly a buffer piston in the form of a hollow cylinder (11). Owing to various embodiments, a damping effect can be obtained in an extreme position either on one or both sides. The piston rod (10), the pistons (4) and the buffer pistons (11) can have the form of hollow cylinders.
