Patent ID: 8561582

Claim:
A device for variably adjusting valve timing of gas exchange valves of an internal combustion engine, comprising: a drive element; an output element; and a camshaft, the drive element being connectable via a drive connection with a crankshaft of the internal combustion engine, the output element being connected fixedly to the camshaft so as to rotate with the camshaft and being arranged pivotably with respect to the drive element, an axial side face of the camshaft bearing against an axial side face of the output element, the camshaft defining first pressure medium lines that open at the axial side face of the camshaft via first openings, and the output element defining second pressure medium lines that open at the axial side face of the output element via second openings, the first openings respectively corresponding to the second openings, wherein one of: an extent of the second openings is greater in a radial direction and in a circumferential direction than an extent of the respective corresponding first openings; and an extent of the first openings is greater in a radial direction and in a circumferential direction that an extent of the respective corresponding second openings; and a positively locking element which engages into a mating positively locking element of the other component being provided on one of the axial side faces which lie on one another, for orienting the output element on the camshaft with regard to its circumferential direction, wherein the positively locking element and the mating positively locking element are formed in one piece with the corresponding component.
