Catalyzer for detoxifying exhaust gases from internal combustion

Claim 1

In a catalyzer for detoxifying exhaust gases from internal combustion engines, wherein a monolithic catalyst body having an outer surface and facing ends is supported in a housing having an inner surface, by support means arranged between said inner surface of said housing and said outer surface of said monolithic catalyst body, the improvement wherein said support means comprises a layer of elastically yielding means, said layer extending at least partially between each facing end of said monolithic catalyst body and said housing, whereby the monolithic catalyst body is elastically restrained in said housing against movement in all three dimensions of space, said layer of elastically yielding means extending radially inwardly across said facing ends and then folding radially outwardly towards said inner surface, to form bends which bends are compressed between said facing ends and said housing, the bends in said layer forming elastically deformable damping means to restrain said catalyst body and form a substantially gas tight barrier, thereby substantially preventing the flow of gas into the space between the catalyst body and the inner surface of the housing.
