Abstract
An improved catalytic converter for the exhaust gases of an automotive engine is disclosed, the converter including a plurality of honeycomb type catalyst carrier elements, annular spacer members and cushioning rings mounted in compressed sandwich fashion within a cylindrical casing section so that the only rigid connection is between the ends of the assembled sandwich and the casing, the cushioning rings being formed of compressed metallic wires and having a triangular cross-sectional configuration which compressively engages within correspondingly shaped annular spaces at the ends of the carrier elements so that the compressive forces of each cushioning ring are transmitted to the associated carrier element with a radially inward component and a longitudinally inward component.
