<p>EXHAUST SEAL RING The outlet of an exhaust manifold for a transversely mounted vehicle engine is coupled by an articulated connection with the inlet of an exhaust header. The articulated connection has portions associated with the manifold and header respectively and includes an annular seal ring with a spherical sealing surface thereon. The sealing surface engages a conical seating surface on the manifold at the urging of a spring between the manifold and header. The seal ring is composed of many metal wires which are packed together to define the annular structure and thus produce a wear resistant, relatively impervious sealing surface having a slight resiliency to permit good sealing conformation against an imperfectly formed geometric seating surface.</p> |
