CATALYTIC CONVERTER WITH AIR TUBE

摘要

C-3081 D-3,565 In a catalytic converter, an air tube is permanently fixed and sealed at an open end thereof between two flanges on one side of a clamshell type housing enclosing reducing and oxidizing catalyst means. The tube extends between the catalyst means and has a closed end slidably mounted between flanges of the housing on the opposite side thereof internal of where these flanges are joined. The tube which has holes for delivering air into the passing exhaust gases prior to reaching the oxidizing catalyst is thus firmly supported by the housing while relative expansion with heat is permitted therebetween and without interrupting the sealed integrity of the housing flanges at the closed end of the tube.
