Therein, the spindle (7) is connected to the damping piston (5) such that a rotation of the spindle (7) moves the damping piston (5). Further, at least one telescopic damping spring unit (9) is connected to the damping piston (5) such that the rotation of the spindle (7) and the movement of the damping piston (5) are damped by the telescopic damping spring unit (9).
