Abstract

Schwenkmotoren für Nockenwellenverstelleinrichtungen haben einen Stator (1) und einen Rotor (8),die koaxial zueinander angeordnet sind und jeweils Flügel (6; 10) aufweisen. Die Rotorflügel (6; 10) liegen an einer Innenwand (5) des Stators (1) und die Statorflügel (6; 10) an einem Mantel eines Grundkörpers (9) des Rotors (8) an. Um die Lekkageverluste gering zu halten und eine einwandfreie Verstellung der Nockenwelle zu ermöglichen, sind die Rotorflügel (6; 10) von ihrer Stirnseite aus in Richtung auf den Grundkörper (9) des Rotors (8) unstetig verjüngt. Dadurch wird die Spaltlänge zwischen der Stirnseite der Rotorflügel (6; 10) und der Statorinnenwand (5) vergrößert, so daß Leckageverluste nur noch minimal sind. Der Schwenkwinkel des Rotors (8) zum Stator (1) wird nicht beeinträchtigt. Der Schwenkmotor wird bei Kraftfahrzeugen zur gezielten Einstellung der Öffnungsdauer von Gaswechselventilen des Verbrennungsmotors herangezogen.
