Abstract

See full text

The invention concerns a shock absorber for motor vehicles having a vibration absorber tube (1), in which a working piston (3) is arranged which is fixed to a piston rod (2), a closure pack (16) which closes the vibration absorber tube (1), and guides the piston rod (2), along with an outer tube (4) which surrounds at least partly the vibration absorber tube (1), wherein the outer tube (4) is connected rigidly to the piston rod (2) outside the vibration absorber tube (1). In order to achieve a shock absorber whose height may be adjusted by simple means, without needing additional installation space for the shock absorber, it is proposed in accordance with the invention that at least one sealing element (15) is arranged between the vibration absorber tube (1) and the outer tube (4), that the connection between the outer tube (4) and the piston rod (2) is designed to be fluid-tight and the chamber H defined by the outer tube (4) and the vibration absorber tube (1) comprises a connector (11) for feeding in a working fluid.
