Abstract
Aufgabe der Erfindung ist es, eine Axialturbine mit einem verbesserten Wirkungsgrad zu schaffen. Zudem sollen die Montage- bzw. Demontagemöglichkeiten erweitert werden.The object of the invention is to provide an axial turbine with improved efficiency to accomplish. In addition, the assembly and disassembly options are to be expanded become.
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. This is achieved according to the invention in that the parting line (17) from the outer ring (12) of the nozzle ring (15) to the cover (8) is arranged on the rotor blade side of an imaginary plane (20) running through half the gap width (19) of the axial gap (18) ,
