Abstract

Die vorliegende Erfindung betrifft eine Anordnung zur Abdichtung eines Übergangs zwischen einer ersten Passage (1a) für ein Kühlmedium in einer ersten Komponente (1) einer Turbomaschine, insbesondere Gasturbine, und einer zweiten Passage (2a) für das Kühlmedium in einer zweiten Komponente (2) der Turbomaschine. Bei dieser Anordnung sind die beiden Komponenten (1) und (2) so ausgebildet und gegenseitig angeordnet, dass in einem Ruhezustand der Turbine am Übergang zwischen den beiden Passagen (1a) und (2a) ein Spalt (3) vorhanden ist, der sich bei Betriebstemperatur der Turbomaschine durch unterschiedliche thermische Ausdehnung der beiden Komponenten (1) und (2) schließt.
Die vorliegende Anordnung ermöglicht eine zuverlässige Abdichtung des Übergangs zwischen den Kühlpassagen zweier Komponenten mit einer minimalen Anzahl von Einzelteilen.
