Advertise in other cases this duxah aquaerte brought about. 3o is öjs so far noeh.-nict elsgen a leisiDgstase N eheap low-noise and qualmsichye exhaust system. This becomes: Lrd by the following Nerkmsl mieism'ndr iFeinig-be Merbale-1ïl. iteina. nar ve:: r: agree. will : di, e SfRgrimnän e. llsäi'Mg perforated Abs-orpt: Lonsmante1. a, b) an absorption space enclosing the absorption jacket, provided with a heat-insulating filling and closed off to the outside by a second jacket, c) a sound-insulated outer damping jacket surrounding the absorption chamber and expediently also the exhaust gas supply. In a special way, this is also achieved in that the silencer connected to the perforated absorption jacket is designed as a multi-chamber damper that is identical in space and wall with this absorption jacket.

Auch kann die geschilderte Wirkung weiter noch dadurch erhöht werden, daß die Eingangskammer des Abshrptionsmantels einen Teil der durch die Abgasleitung und den Schalldämpfer gebildeten Resonanzlage bildet. Aus diesem Grunde ist es zweckmäßig, wenn die Eingangskammer des Absorptionsmantels die Eingangskammer des Mehrkammerdämpfers bildet. Durch die oben geschilderten Maßnahmen wird auf einfachste Weise eine leistungsstarke, geräuscharme und qualmsichere Abgasanlage geschaffen.The described effect can also be further increased by that the inlet chamber of the Abshrptionsmantels part of the through the exhaust pipe and forms the resonance layer formed by the muffler. For this reason it is advisable to when the entrance chamber of the absorption jacket is the entrance chamber of the multi-chamber damper forms. With the measures outlined above, a powerful, Low-noise and smoke-proof exhaust system created.

Um auch in konstruktiver Hinsicht den durch die genannte Aufgabenstellung bedingten Forderungen gerecht zu werden, wird vorgeschlagen, daß nach einem weiteren Merkmal der Erfindung der Absorptionsmantel auf der den Absorptionsraum begrenzenden Hülle wärmeverschieblich gelagert ist.In order to meet the requirements mentioned in a constructive manner To meet conditional requirements, it is proposed that after another Feature of the invention of the absorption jacket on the delimiting the absorption space Sheath is mounted so that it can move in heat.

Dadurch werden die durch die Wärmeübertragung der Abgase bedingten Wrmespannungen aufgehoben und ein unerwünschtes Verwerfen des Materials verhindert. This will reduce the heat transfer through the exhaust gases caused thermal stresses and an undesirable Discarding the material prevented.
