A guide tube arranged in a pressure tube. A piston is guided in the guide tube. A piston rod is fastened to the piston, and extends through a second work chamber guided outward by a sealing and guiding device at a first end of the pressure tube and is arranged with its other end at the base part of the vertical tube. A flow connection between the first work chamber and the second work chamber can be shut off by a valve which can be actuated by an actuating device. The pressure tube is arranged to be movable along the center longitudinal axis relative to the telescope tube.
