ABSTRACT:
An elongate catalytic muffler of the radial flow type for purifying the exhaust gases of an internal combustion engine, comprises a tubular casing having a gas inlet at one end and a gas outlet at the other end. Two co-axial substantially parallel frustra-conical grids of decreasing cross-section from the inlet end to the outlet end of the muffler define, with cup-like end walls, a catalyst chamber compression means is provided for axially displacing one of said end walls towards the other, so as to compress the catalyst mass in said chamber, and with said compression means being protected by tight separating means from the action of the exhaust gases treated in the muffler.
