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.

1. A sealing device (13) for sealing an assembly (10) which comprises two parts (11, 12), of which one part (11) is provided with the sealing device (13), while the other part (12) has a face (14) which is engaged by the sealing device (13):the sealing device (13) being embodied on the face end of one wall (16) of the first part (11) and having a groove (20), which extends along the face end and is bounded on both sides by groove cheeks (22, 25); the groove cheek (22) located toward the outside (17) of the wall (16) being braced on the face (14) of the second part (12), while the groove cheek (25) located toward the inside (24) of the wail (16) extends with spacing from the face (14); a rubber-elastic seal (27) disposed in the groove (20), which seal in the unstressed state protrudes past both groove cheeks (22, 25) and in the stressed state is forced back at least approximately as far as the groove cheek (22) toward the outside, the groove cheek (22) toward the outside having a protrusion (23) of luglike cross section, adjoining the groove (20), which protrusion, by plastic deformation, engages the face (14) of the second part (12); the groove cheek (25) toward the inside is embodied in cross section as a wedge, which has a rounded tip and which comes to an end at its wedge angle in a bottom (21), embodied as flat, of the groove (20). 2. The sealing device of claim 1, wherein the seal (27) is essentially incompressible and in the unstressed state has a cross section that not only fills up the groove (20) but also at least approximately semicircularly protrudes past the two groove cheeks (22, 25).3. The sealing device of claim 2, wherein the seal (27) comprises silicone rubber.4. The seating device of claim 1, wherein the groove cheek (25) toward the inside protrudes upward from the bottom (21) of the groove (20) to at most half the depth of the groove.5. The sealing device of claim 1, wherein the bottom (21) of the groove (23) extends at least approximately parallel to the face (14) of the second part (12).6.
