Abstract
The invention relates to a housing sealing cover (1, 10, 15, 18) for detachable liquid-tight fixing to an internal combustion engine, comprising an add-on piece (24) which is firmly connected to the housing, extending through the cover when in a mounted position. Said cover consists of a metallic or polymer support element (2) made of a single layer and is provided with an opening (25) for the add-on piece (24), wherein a seal (23) is arranged in said opening. Said seal comprises a sealing lip(3, 11) extending axially on the edge (26) of the opening (25) and a sealing lip (5, 12, 16, 19) extending radially in relation to the seal of the add-on piece (24). The radially extending sealing lip (5, 12, 16, 19) is retained in the opening (25) in an angularly and radially displaceable manner with respect to the support element (2).
