Abstract (en)
[origin: EP0684391A1] The piston is secured to a piston rod (15) and slides in the cylinder chamber between two end positions. It is bushed during its motion by a damping bush (22) on the piston rod, with the damping bush entering a through bore (19) for throttled outflow of the pressure medium to a cylinder connecting union. Thus the piston moves slowly to its end position. To the damper in allocated a non-return valve for unobstructed pressure application to the cylinder chamber. The damping bush is freely axially guided on the piston rod between two stops (23,24). One end (29) of the bush, at the stop (23) allocated to the through bore, forming a valve (31) with a non-return function.
