Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
178 words
A device for the detoxification of the exhaust gases of combustion engines in motor vehicles comprising a monolithic metallic catalyst body, and a housing enclosing said catalyst body in a shock-resistant manner in its interior, said housing and catalyst body permitting flow-through of exhaust gases in an axial direction, said catalyst body having a circumferential surface, parallel to said flow-through direction, and resting against the interior of said housing, and said housing having at least one nose projecting inwardly against each facing end of said catalyst body said device being characterized by the following characteristics: (a) the housing is a sheet-metal housing, in which said noses are formed as impressions in said sheet metal; (b) said noses extend only in the vicinity of the circumferential edges of the catalyst body and project, each, axially toward the appropriate facing end, so that their heads rests against said facing ends; (c) each impression that forms a nose is shaped in such a way, that the housing wall, opposed to the circumferential surface of the catalyst body is also slightly extended.
Claim 2
Independent Claim
178 words
A device for the detoxification of the exhaust gases of combustion engines in motor vehicles comprising a monolithic metallic catalyst body, and a housing enclosing said catalyst body in a shock-resistant manner in its interior, said housing and catalyst body permitting flow-through of exhaust gases in an axial direction, said catalyst body having a circumferential surface, parallel to said flow-through direction, and resting against the interior of said housing, and said housing having at least one nose projecting inwardly against each facing end of said catalyst body said device being characterized by the following characteristics: (a) the housing is a sheet-metal housing, in which said noses are formed as impressions in said sheet metal; (b) said noses extend only in the vicinity of the circumferential edges of the catalyst body and project, each, axially toward the appropriate facing end, so that their heads rests against said facing ends; (c) each impression that forms a nose is shaped in such a way, that the housing wall, opposed to the circumferential surface of the catalyst body is also slightly extended.
Claim 3
Dependent Claim
46 words
A device according to claim 1 in which said housing comprises two half-shells, the noses of each half-shell being preformed to their approximate final shape and being final-formed to their resting points against the facing ends of the catalyst body only after assembly of said half-shells.
