The invention relates to a sealing device (1), comprising a housing (2), which encloses a piston rod (4) and which has at least one annular groove (8-11) on the cylindrical inner face of the housing facing the piston rod (4), into which at least one annular groove a sealing ring (12-15) in the form an annular disk is inserted, which sealing ring lies against the piston rod (4) by means of sealing lips (22), wherein the annular groove (8-11) has, on opposite side walls (18, 19), at least one elevation (16, 17), which presses against the sealing ring (12-15) lying in the annular groove and, in at least one annular groove (8, 11), elevations (16, 17) are arranged opposite each other in the region of the groove opening (20) of the annular groove pointing toward the piston rod (4), which elevations damp lateral motions of the sealing ring (12-15). |
