Abstract
An internal combustion engine is provided with a sound-insulating enclosure (2), which defines a sealed passage extending through the enclosure. A passage which extends through the enclosure is sealed by a sealing ring (9), which consists of a rubber-elastic material and is disposed between an inner flanged ring (7), which is secured to the engine, and an outer flanged ring (8), which is secured to the enclosure (2). In order to provide sealing means which are satisfactory for a passage for the exhaust manifold (3), the inner flanged ring (7) carries a protective shield (10), which shields the inside surface of the sealing ring (9) and which defines with the sealing ring (9) a clearance (12), which contains a heat-resisting and sound-absorbing insulating material (11).
