Beschreibung
Zusammenfassung:	The invention relates to a vibration damper having a hydraulic traction stop for a motor vehicle wheel suspension, comprising a reservoir tube (2"), a piston rod (3") and a hydraulic damping device (10") having a damping piston (11") fastened on the piston rod (3), which provides a hydraulic force directed against the tractive motion of the piston rod (3") in an end region of a piston rod extraction path before reaching the maximum piston rod extraction path. The damping piston (11") has a circumferential groove (12") in which a slotted sealing ring (16") is received, which hydraulically sealsin the groove (12") in said end region of the piston rod extraction path upon movement of the piston rod (3") in the traction direction and, upon movement of the piston rod (3") in the pressure direction at least locally rises from a flank (14") of the groove (12") on the pressure direction side, which delimits the groove (12") on the side in the pressure direction and in the traction direction,in order to provide a defi
