ABSTRACT:
A fluid-filled piston-cylinder unit with a tubular fluid-filled housing closed at one end and with a piston rod emerging from the other end comprising, for guiding the said piston rod, a guide bush which is sealed on the one hand against the inside wall of the housing and on the other against the piston rod by the use of seals. Provided at the inner end of the piston rod there is a guide piston. In order on the one hand to avoid surface pressure between the piston rod and the guide bush and on the other to achieve an adequate length of guidance for the piston rod itself, the guide bush is provided with at least one spacer extending in axially parallel manner beyond the seals and in the direction of the guide piston and the cross-section of which is substantially smaller than the cross-section of the guide bush.
