ABSTRACT:
Piston-cylinder assembly, comprising a container tube, in which a piston rod is guided with freedom of axial movement, which rod is at least partially covered by a sheath tube with at least one elastic fold, where a resilient stop pad is provided concentrically to the piston rod, the end of which pad comes to rest against an end cap during the inward travel of the piston rod, which end cap rests against the container tube in the fully assembled piston rod assembly. The stop pad, the sheath tube, and the end cap form a preassembled unit which is independent of the piston rod assembly, the end cap being pressed onto the container tube by the resilient stop pad during the inward travel of the piston rod into the container tube.
