Abstract

Diese Vorrichtung ist für eine Brennkraftmaschine geeignet und umfasst ein Zellenrad (17) und ein Flügelrad (14), das relativbeweglich im Zellenrad gelagert ist und über Druckkammern und mittels Öl hydraulisch betätigt wird, wobei das Öl durch axiale Leitungen in Druckkammern gelangt, die einerseits zwischen einem Schaft einer axialen von einer Stirnseite der Nockenwelle eingebrachten Befestigungsschraube und einer den Schaft umgebenden in wenigstens einer Aufnahmebohrung ruhenden Steuerhülse und andererseits zwischen der Steuerhülse und einer koaxial zu letzterer angeordneten Bohrung einer Nabe ausgebildet sind.
Zur günstigen Gestaltung der Leitungen mittels der Steuerhülse und einfachen Montage der Steuerhülse sind letztere und die den Schaft aufweisende Befestigungsschraube von der gleichen Stirnseite aus eingeführt, welche Steuerhülse in entsprechenden Aufnahmebohrungen der Nabe ruht.
