Abstract
A sealing lip seals a first space from a second space with respect to a liquid medium present in the first space. The sealing lip has abutment surface configured to abut on a sealing surface of a component that is movable relative to the sealing lip along a direction of movement. A groove is defined in the abutment surface and pumps any liquid medium present in the groove towards the first space along the direction of movement. The groove extends completely within the abutment surface and is enclosed by the abutment surface, such that it does not intersect either lateral edge of the sealing lip.
