Abstract: A device for purifying exhaust gases of an internal combustion engine comprises a tubular housing with an exhaust gas inlet at one end and an exhaust gas discharge at the opposite end, and with a catalyst carrier disposed in the housing between the inlet and the discharge, which has a plurality of axially extending gas passages with a catalyst therein for the passage of exhaust gases therethrough, for the purification thereof. A ring is disposed in the tubular housing adjacent each end of the catalyst carrier and it has an interior diameter which is less than the outer diameter of the catalyst so that the gases are deflected inwardly around the ring. To ensure that the gases do not pass over the periphery of the catalyst carrier into an insulation space and without passing through the catalyst containing passages, a foil sheet is provided which extends over the periphery of the catalyst carrier and is secured to and sealed with the ring.

Abstract: A device for the catalytic purification of exhaust gases of internal combustion engines comprising 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 therethrough. 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.
