Mounting for a metallic exhaust gas catalyst carrier body and method for manufacturing the same
First Claim
1. Mounting assembly for an exhaust gas catalyst, comprising a metallic exhaust gas catalyst carrier body formed of a multiplicity of layers, at least one first brazed joint interconnecting said layers, a metallic tubular jacket in which said catalyst carrier body is disposed, and one second brazed joint fastening said catalyst carrier body to said tubular jacket while permitting lengthwise expansion of said catalyst carrier body relative to said tubular jacket, said first and second brazed joints being axially spaced apart from each other.

21. Method for manufacturing an exhaust gas catalyst mounting assembly, which comprises:
-
(a) winding sheets together to form a catalyst carrier body; (b) fastening the sheets together with at least at one first brazed joint; (c) slipping at least two collar-shaped spacers on the catalyst carrier body and fastening the spacers to the catalyst carrier body; (d) slipping the catalyst carrier body with the spacers into a tubular jacket while maintaining a space between the catalyst carrier body and the tubular jacket and simultaneously filling the space with a flowable, high-temperature resistant material; and (e) fastening one of the spacers to the tubular jacket with one second brazed joint axially spaced apart from the at least one first brazed joint. - View Dependent Claims (22, 23, 24, 25, 26)
