Abstract (en)
The cylinder has a piston (4) supported in a longitudinal displaceable manner between two end positions. A damping device for damping the movement of the piston has a retaining opening (15) and a casing (19), in which the opening is provided at an end part. The opening and the casing are inserted into one another in the piston movement direction, where the casing is movable to an end position during the convergence of the piston at its end positions. The casing is movable to another end position and again returns to its initial position, when the piston moves away from its end position.
