A device for variably adjusting the valve timing of gas exchange valves of an internal combustion engine which has an input element, an output element and a camshaft. The input element can be brought in a driving connection with the crankshaft of the internal combustion engine. The output element is non-rotationally connected to the camshaft and swivelable in relation to the input element. An axial lateral face of the camshaft rests against an axial lateral face of the output element. A form-locking element on one of the axial lateral faces resting against each other aligns the output element on the camshaft with respect to its circumferential direction and engages in a mating form-locking element of the other component.

Device for variably adjusting the valve timing of gas exchange valves of an internal combustion engine

A device () for the hydraulic adjustment of the angle of rotation of a camshaft () in relation to a crankshaft of an internal combustion engine, situated at the drive-side end () of the camshaft () and formed of a drive unit () that stands in a driven connection with the crankshaft and an output unit () that is connected in rotationally fixed fashion with the camshaft () is provided. The drive unit () stands in a force-transmitting connection with the output unit () via at least two pressure chambers () formed inside the device (), the supply of pressure medium to the pressure chambers () taking place via a separate distributor housing () that has a connecting flange () suitable for transmitting pressure medium to the device () and a control valve receptacle () that is connected to the connecting flange () via two pressure medium conduits (). The output unit () is fastened non-positively to the camshaft (), which passes through the device axially with its drive-side end () and has a hollow construction, the end segment () of the camshaft () being enclosed by the connecting flange () of the distributor housing () and having a plurality of radial bores () that stand in pressure medium connection with additional radial bores () in the camshaft () via a distributor insert () that can be placed into the hollow space () of the camshaft ().
