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.This device is suitable for an internal combustion engine and comprises a cellular wheel (17) and an impeller (14) which is relatively movable in the cellular wheel and via pressure chambers and is actuated hydraulically by means of oil, the oil being passed through axial lines in Pressure chambers reaches, on the one hand, between a shaft of an axial one The front side of the camshaft is fitted with a fastening screw and the shaft surrounding control sleeve resting in at least one receiving bore and on the other hand, arranged between the control sleeve and one coaxial to the latter Bore of a hub are formed.

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.

Figure 00000001
For the favorable design of the lines by means of the control sleeve and simple assembly of the control sleeve, the latter and the fastening screw having the shaft are inserted from the same end face, which control sleeve rests in corresponding receiving bores in the hub.
