Abstract

One part of an assembly has one wall with a face-end groove in which a rubber-elastic seal is disposed. In the unstressed state, the seal protrudes past two groove cheeks of the groove. The groove cheek toward the outside is provided with a luglike protrusion while the groove cheek toward the inside has a lesser height than the groove cheek and is wedge-shaped in cross section. The protrusion of the outside groove cheek together with the seal forms a sealing device, whose action in the stressed state is based on the one hand on the plastic deformation of the protrusion on a face of a second part and on the other on the high pressure of the seal in the groove.
