Abstract

Die Erfindung betrifft eine Vorrichtung (10) zur variablen Einstellung der Steuerzeiten von Gaswechselventilen (9a, 9b) einer Brennkraftmaschine (1) mit einem Antriebselement (22), einem Abtriebselement (23), einer Drehwinkelbegrenzungsvorrichtung (42, 43) und einem Steuerventil (37), wobei zumindest zwei gegeneinander wirkende Druckkammern (35, 36) vorgesehen sind, wobei durch Druckmittelbeaufschlagung einer der Druckkammern (35, 36) bei gleichzeitiger Entleerung der andern Druckkammer (35, 36) eine Phasenverstellung zwischen dem Abtriebselement (23) und dem Antriebselement (22) hervorgerufen werden kann, wobei die Drehwinkelbegrenzungsvorrichtung (42, 43) in einem eingeriegelten Zustand eine Änderung der Phasenlage verhindert, wobei die Drehwinkelbegrenzungsvorrichtung (42, 43) in einem entriegelten Zustand eine Änderung der Phasenlage zulässt, wobei die Drehwinkelbegrenzungsvorrichtung (42, 43) durch Druckmittelbeaufschlagung von dem eingeriegelten in den entriegelten Zustand überführt werden kann, wobei das Steuerventil (37) ein Ventilgehäuse (52) und einen Steuerkolben (54) aufweist, wobei an dem Ventilgehäuse (52) zumindest jeweils ein Zulaufanschluss (P), ein Ablaufanschluss (T), ein erster und ein zweiter Arbeitsanschluss (A, B) und ein dritter Arbeitsanschluss (Steueranschluss (S)) ausgebildet sind und wobei die Arbeitsanschlüsse (A, B, S) axial zueinander versetzt und nicht überlappend an dem Ventilgehäuse (52) ausgebildet sind.
