A dashpot featuring amplitude-dependent shock absorption, especially intended for the wheel of a vehicle and including a hydraulically parallel cylindrical pressure-compensation chamber (). The pressure-compensation chamber is partitioned by an axially displaceable floating piston (). At least one face () of the floating piston is provided with a resilient bumper (). The object is a dashpot with a floating piston that arrives more gently at its limit inside the pressure-compensation chamber (). The bumper is accordingly accommodated in an axial hollow () that extends through the body () of the floating piston.

A piston rod has a hollow section with an open end, a housing, and a fastening connection for a piston. The housing includes a cap welded to the open end, a tubular intermediate piece welded to the cap, and a bottom part attached to the fastening connection. The cap has a shoulder received in the intermediate piece to form an annular space which functions as a labyrinth seal to receive any weld spatters formed during the friction welding process. The outside surface of the piston rod is machined to final dimensions and surface coated following welding.
