Abstract

Ein Schalldämpfer, insbesondere für die Abgase einer Verbrennungskraftmaschine, mit einem Gehäuse (14) und mindestens einer im Gehäuse angeordneten Hohlkammerstruktur (20), ist dadurch gekennzeichnet, daß das Gehäuse (14) mit mindestens einem nach innen ragenden Vorsprung (24) versehen ist, mittels dem die Hohlkammerstruktur (20) im Inneren des Gehäuses (14) arretiert ist.

Figure imgaf001
A silencer, in particular for the exhaust gases of an internal combustion engine, having a housing (14) and at least one hollow chamber structure (20) arranged in the housing, is characterized in that the housing (14) is provided with at least one inwardly projecting projection (24), by means of which the hollow chamber structure (20) is locked in the interior of the housing (14).
