摘要

The sealing ring has a curved sealing lip (3), in the direction of the zone to be sealed, with at least one opening (5.1) on the radial side away from the machine unit (4). The sealed zone (2) is linked to the ambient environment (6) by the opening (5.1) only on a faulty installation of the sealing ring (1) and the curvature of the sealing lip (3).
