Exhaust gas ducting used with engine-independent heater of motor vehicle has one-piece flexible inner helical pipe with sound-insulated perforated long section and encompassed gastight by one-piece flexible outer pipe

The whole exhaust ducting, including the silencer, is constructed by flexible helical pipes. The ducting has a one-piece flexible inner pipe(2) which has a perforated long section enclosed by a sound insulating material(4) such as rock wool or suchlike, and encompassed gastight by a one-piece flexib...

description	The whole exhaust ducting, including the silencer, is constructed by flexible helical pipes. The ducting has a one-piece flexible inner pipe(2) which has a perforated long section enclosed by a sound insulating material(4) such as rock wool or suchlike, and encompassed gastight by a one-piece flexible outer pipe(3). The perforated section of the inner pipe has local pinched-in sections(5) with flat points lying opposite each other. The inner and outer pipes are located concentrically in relation to each other. Bei einer Abgasführung (1) mit Schalldämpfer in einem Anschluß (A) an ein motorunabhängiges Heizgerät eines Kraftfahrzeuges bis hin zum Abgasauslaß (B) wird vorgeschlagen, die gesamte Abgasführung einschließlich Schalldämpfer durch flexible Wendelrohre (2, 3) auszubilden, wobei insbesondere eine einstückiges flexibles inneres Wendelrohr einen perforierten Längenabschnitt besitzt, der mit einem schalldämmenden Material (4) wie Steinwolle oder dergleichen umgeben und durch ein einstückiges flexibles äußeres Wendelrohr (3) ab gasdicht eingefaßt ist.
