Abstract

The working cylinder has a blocking bolt (9) in the shape of a hollow tube (10) which projects into a cylinder chamber (2) in a damping region (7). The blocking bolt is axially displaceable against a stop (15) and is held in position by a compression spring (30). In the damping position at the edge of the region (16) of a hydraulic connection (6) the blocking bolt makes a sealing engagement in the manner of a valve body.
