Abstract

Die Erfindung betrifft eine Abgasleitung (1) mit einem in einem Außenrohr (3) unter Ausbildung eines ringförmigen Luftspalts (4) relativ verlagerbaren Innenrohr (2), wobei dem Außenrohr (3) ein Dehnungsausgleicher (9, 10) zugeordnet ist, der durch hydraulische balgartige Umformung der Wandung (11) des Außenrohrs (3) gebildet ist. Jeder Dehnungsausgleicher (9, 10) ist in einem Bereich (13, 14) angeordnet, in dem betriebstechnisch die Dehnungskompensation sinnvoll ist. Die im Betrieb auftretenden Längenänderungen können so wirksam kompensiert werden.
