Abstract

The force/pressure buffer has a housing (1) and piston (2) which moves under steam in both directions. The buffer moves as a single unit with hydraulic damping and the piston has a ring-shaped working area (25) with is sealed with a moving, guided ring piston (11) in a first function chamber (23) and a second function chamber (24). The work is divided between the two chambers which are connected by an overflow channel (22). An axial control rod (29) is in connection with both the function chambers and controls the overflow function and distribution between the two chambers.
