Catalytic converter having resilient monolith-mounting means
A device for the catalytic purification of exhaust gases of internal combustion engines consists of a tubular metal housing having an exhaust gas supply connection at one end and an exhaust gas discharge connection at the opposite end and defining a gas flow passage through it. A tubular casing of sheet metal is disposed within the housing and spaced inwardly from the interior walls of the housing. In addition a substantially cylindrical monolithic catalyst carrier is disposed within the exhaust gas flow passage within the housing and is spaced radially inwardly from the metal casing and has axially extending passages therethrough for the flow of exhaust gases through it. A radially prestressed compacted metal mesh is disposed between the carrier and the casing and forms an elastic support for the carrier. An annular bearing member is disposed at each end of the housing and has an axially extending leg portion connected to a respective end of the tubular housing and to a respective end of the casing. In addition, the bearing member has a radially extending portion which forms an end abutment and an elastic seal ring is disposed between the end abutment and the end of the carrier. In addition a spring member having a substantially U-shaped cross section is oriented with the open U-shape bearing radially outwardly against the interior surface of the elastic seal ring.
