Zusammenfassung:A damper tube which is at least partially filled with damping fluid and in which a piston rod is movable back and forth, wherein a working piston is movable jointly with the piston rod, by means of which working piston the interior space of the damper tube is divided into a piston-rod-side working space and a piston-rod-remote working space. A damping module for the frequency-dependent control of a comfort bypass is formed between the piston-rod-side working space and the piston-rod-remote working space and which comprises a comfort path via which damping fluid can be caused to flow hydraulically in parallel with respect to the flow through the working piston.
