Abstract

Die Erfindung betrifft einen Schalldämpfer (1) für eine Abgasanlage einer Brennkraftmaschine, insbesondere eines Kraftfahrzeugs mit zwei voneinander abgewandten stirnseitigen Endböden (2), einem in Umfangsrichtung geschlossen umlaufenden Mantel (3), wenigstens einem Schalldämpfereinsatz (4), wenigstens einem Einlassrohr (5) und wenigstens einem Auslassrohr (6). Zumindest eines der Rohre (5,6) erstreckt sich durch den Mantel (3) in das Schalldämpferinnere (8) erstreckt und ist am Mantel (3) befestigt.The invention relates to a silencer (1) for an exhaust system of an internal combustion engine, in particular of a motor vehicle with two end faces (2) facing away from one another, a circumferential jacket (3), at least one silencer insert (4), at least one inlet pipe (5). and at least one outlet tube (6). At least one of the tubes (5, 6) extends through the jacket (3) into the silencer interior (8) and is fastened to the jacket (3).

Die Herstellung lässt sich vereinfachen, wenn das sich durch den Mantel (3) erstreckende Rohr (5,6) an seinem innenliegenden Ende einen Konus (10) aufweist, wenn der Schalldämpfereinsatz (4) einen Gegenkonus (11) aufweist und wenn der Konus (10) in den Gegenkonus (11) eingreift.

Figure imgaf001
The manufacture can be simplified if the tube (5, 6) extending through the jacket (3) has a cone (10) at its inside end if the muffler insert (4) has a counter-cone (11) and if the cone (FIG. 10) engages in the counter-cone (11).
