Description
Die Aufgabe der Erfindung besteht darin, einen Verstellrotor der eingangs genannten Art derart weiterzubilden, daß die Verbindungselemente zwischen zwei diametral gegenüberliegenden Rotorblättern so ausgebildet sind, daß mehrere Verbindungselemente in der Nabe befestigt werden können, wobei die Verbindungselemente eine für die Verstellung der Rotorblätter ausreichende Elastizität aufweisen.
Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.
F i g. 1 eine Seitenansicht eines Verstellrotors,
F i g. 2 eine Ansicht des Verstellrotors gemäß F i g. 1 von hinten, im Schnitt und mit teilweise weggebrochenen Teilen,
Jede langgestreckte Lamelle la bis Ic ist aus zwei
