Abstract

Bei einem Abgas-Schalldämpfer (1) in Mehrkammerbauweise, insbesondere Abgas-Schalldämpfer eines Personenkraftfahrzeuges, mit einem Außengehäuse (2) bestehend aus einer oberen und einer unteren Halbschale (3, 4), einer Innenschale (5) sowie einer inneren Abgasführung durch den Abgas-Schalldämpfer, wird vorgeschlagen, die Abgasführung mit zumindest einem ersten gekrümmten Auslaufrohr (9) auszubilden, das einen ersten Krümmungsabschnitt aufweist und dessen vorzugsweise geradliniges Austrittsende (27) bündig mit dem Außengehäuse (2) verläuft. Der Abgas-Schalldämpfer (1) weist insbesondere eine Innenschale auf, die partiell in einen abgewinkelten Umfangsfalz (900) des Abgas-Schalldämpfers (1) eingeklemmt ist.

Figure 00000001
In the case of an exhaust gas muffler (1) in a multi-chamber construction, in particular exhaust gas muffler of a passenger car, with an outer housing (2) consisting of an upper and a lower half shell (3, 4), an inner shell (5) and an internal exhaust gas duct through the exhaust gas Muffler, it is proposed to design the exhaust gas guide with at least one first curved outlet pipe (9) which has a first curved section and whose preferably straight outlet end (27) is flush with the outer housing (2). The exhaust muffler (1) has in particular an inner shell which is partially clamped in an angled circumferential fold (900) of the exhaust muffler (1).
