Abstract

Eine Vorrichtung zur Abdichtung zwischen den Leitschaufeln (1) und dem Rotor (17) von Turbomaschinen, insbesondere von Gasturbinen, besteht aus wärmeelastisch an dem Schaufelfuß (14) der Leitschaufeln (1) aufgehängten Innenringen (3) mit aufgelöteter Wabendichtung (4) und aus auf dem Rotor (17) angebrachten Labyrinthspitzen (5). Durch die Schaufelfüße (14) sind an die von Kühlluft durchströmten Hohlräume (21) der gekühlten Leitschaufeln (1) angeschlossene, erste Strömungskanäle geführt. Die ersten Strömungskanäle sind mit mindestens einem von durch den Innenring (3) bis nahe an die Wabendichtung (4) geführten zweiten Strömungskanälen verbunden. Die zweiten Strömungskanäle münden in mindestens einen von an der hinteren Kante des Innenringes (3) offenen, dritten Strömungskanälen oder sind zu einer zur Wabendichtung (4) hin offenen Ringnut (10) auf der Unterseite des Innenringes (3) geführt.
