Abstract

Aufgabe der Erfindung ist es, einen Düsenring für die Abgasturbine eines Turboladers zu schaffen, welcher neben einer verbesserter Lebensdauer auch einen konstanten Wirkungsgrad garantiert.The object of the invention is to provide a nozzle ring for the exhaust gas turbine of a turbocharger to create, which in addition to an improved lifespan also a constant efficiency guaranteed.

Erfindungsgemäss wird dies dadurch erreicht, dass zwischen dem Turbinengehäuse (2) und dem Düsenring (11) ein radialer Dehnungsspalt (20) ausgebildet und im Dehnungsspalt (20) zumindest eine Dichtung (22) angeordnet ist. Dazu ist in zumindest einem der Befestigungselemente (16, 17) des Düsenrings (11) oder in zumindest einem der die Befestigungselemente (16, 17) umgebenden Bauteile (3, 4, 5) des Turbinengehäuses (2) eine die Dichtung (22) aufnehmende, umlaufende Nut (21) ausgebildet.

Figure 00000001
According to the invention, this is achieved in that a radial expansion gap (20) is formed between the turbine housing (2) and the nozzle ring (11) and at least one seal (22) is arranged in the expansion gap (20). For this purpose, at least one of the fastening elements (16, 17) of the nozzle ring (11) or in at least one of the components (3, 4, 5) of the turbine housing (2) surrounding the fastening elements (16, 17) has a seal (22) , circumferential groove (21) formed.
