Title: Device for purifying exhaust gases

Abstract

The invention discloses a device for purifying exhaust gases of an internal combustion engine comprised of 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. The securement may take place between a small diameter portion of the outer housing and the ring, or between the outer edge of an angle shaped ring and the foil sheet. The foil sheetmore » may extend inwardly from each end and overlap in the center or be extended only a few inches over each end of the catalyst carrier so as to ensure the correct flow of the exhaust gases.« less
