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. In an exhaust gas silencer (1) in multi-chamber construction, in particular exhaust gas silencer of a passenger vehicle, with an outer casing (2) consisting of an upper and a lower half-shell (3, 4), an inner shell (5) and an inner exhaust gas routing through the exhaust gas mufflers, it is proposed to form the exhaust duct with at least one first curved outlet pipe (9) having a first curved portion and extends its preferably rectilinear outlet end (27) flush with the outer housing (2). Der Abgas-Schalldämpfer (1) weist insbesondere eine Innenschale auf, die partiell in einen abgewinkelten Umfangsfalz (900) des Abgas-Schalldämpfers (1) eingeklemmt ist. The exhaust silencer (1) in particular has an inner shell which is sandwiched partially in an angled circumferential fold (900) of the exhaust gas silencer (1).
