Abstract
An absorption/reflection exhaust muffler of multichamber design with an outer housing and two inner half shells, in which the exhaust gas duct is impressed or pressed in, and which form the inner partitions of the individual chambers. The two inner half shells are designed as a prefabricated, inner half shell system with a bent together edge section, which is pressed in into the outer housing. Compensation of expansion during thermal stresses between the inner half shells and the outer housing is possible as a result. The outer housing may optionally be an outer shell manufactured according to the winding technique, i.e., a wound outer jacket with two flat outer bottoms, or it may comprise two outer half shells manufactured according to the half shell technique.
