Abstract

Aufgabe der Erfindung ist es, eine Axialturbine mit einem verbesserten Wirkungsgrad zu schaffen. Zudem sollen die Montage- bzw. Demontagemöglichkeiten erweitert werden.
Erfindungsgemäss wird dies dadurch erreicht, dass die Trennfuge (17) vom Aussenring (12) des Düsenringes (15) zur Abdeckung (8) laufschaufelseitig einer durch die halbe Spaltweite (19) des Axialspaltes (18) verlaufenden, gedachten Ebene (20) angeordnet ist.
