Abstract

Die vorliegenden Erfindung betrifft einen Schalldämpfer (1), insbesondere einen Abgasschalldämpfer für ein Heizgerät, insbesondere für eine Standheizung oder für einen Zuheizer eines Kraftfahrzeugs. Der Schalldämpfer (1) weist ein Gehäuse (2) auf, in dem wenigstens ein durchströmbarer, schalldämpfender Absorber (3) angeordnet ist. Des Weiteren umfasst der Schalldämpfer (1) einen Gehäuseeinlaß (4) und einen Gehäuseauslaß (5).
Eine besonders preiswerte Herstellbarkeit ergibt sich dann, wenn der Absorber (3) und/oder das Gehäuse (2) durch Metallschaumformteile (7, 8) gebildet sind.
