Abstract

Eine Brennkraftmaschine mit einer hydraulischen Vorrichtung (1) zur Drehwinkelverstellung einer Nockenwelle (2) gegenüber einer Kurbelwelle umfasst einen Rotor in Flügelradform (7), der über eine Zentralschraube (6) drehfest mit der Nockenwelle verbunden ist und einen Stator (4), der sich synchron mit einem von der Kurbelwelle angetriebenen Antriebsrad (3) dreht, wobei beiderseits von Flügeln des Rotors Druckkammern vorgesehen sind, die jeweils durch radial verlaufende Wände des Stators (4) begrenzt sind und über ein Hydrauliksystem mit Hydraulikflüssigkeit befüllt und entleert werden können, wobei die Hydraulikflüssigkeit zum einen über einen Ringspalt (13) zwischen Rotor (7) und Zentralschraube (6) und zum anderen durch im Wesentlichen axiale und radiale Kanäle in die Druckkammern geleitet wird. Durch den Einsatz eines Rotors (7) mit einer in Umfangsrichtung verlaufenden Nut (10) und ein an die Vorrichtung angepassten ringscheibenförmigen Zwischenelements (9) kann die Brennkraftmaschine mit einer Vorrichtung (1) zur Drehwinkelverstellung ausgerüstet werden, bei der die Anzahl und/oder Anordnung der axialen Kanäle zur Hydraulikflüssigkeitsversorgung nicht mit denen der Nockenwelle der Brennkraftmaschine übereinstimmen. Diese Bauweise ermöglicht die Verwendung der Vorrichtung (1) an vielen, unterschiedlichen Brennkraftmaschinen, ohne dass die Vorrichtung (1) aufwändig angepasst werden muss.
