Abstract

Die Erfindung betrifft einen Schalldämpfer mit einem Gehäuse dessen Innenvolumen zur Dämpfung von vorgegebenen Schallwellen ausgelegt ist. Über Anschlüsse (2) wird das die Schallwellen tragende Medium angekoppelt. Das Gehäuse ist aus zwei gleich gestalteten Gehäusehälften (1) mit Halbringen (4,6,7,8) und Stegen (5) an der Verbindungsstelle jeweils korrespondierend zusammengesetzt, wobei jeweils eine Gehäusehälfte (1) einen der Anschlüsse (2) trägt.

The invention relates to a silencer with a housing whose internal volume is designed to dampen predetermined sound waves. The medium carrying the sound waves is coupled via connections (2). The housing is composed of two identically designed housing halves (1) with half rings (4,6,7,8) and webs (5) at the connection point, each housing half (1) carrying one of the connections (2).
