Assembly for use between bodies e.g. cylinder heads, of internal combustion engine on motor vehicle, has groove extending on edge, and projection and sealing unit engaged partially in groove

摘要

The assembly (1) has bodies (3, 4) respectively presenting faces (30, 40), where one of the faces has a projection (300) along an edge (50). The other face has a groove (400) extending with respect to the projection. A sealing unit (7) i.e. joint, is deformed under pressure, arranged between the faces and subjected to compressive force (F) by a connection unit (6). The sealing unit seals an interior volume (51) of a unitary assembly (5) with respect to an outer portion (52) of the bodies. The groove extends on the edge. The projection and the sealing unit are engaged partially in the groove. The sealing unit is made of a material chosen among elastomer and silicone with Newtonian rheological characteristics.
