Abstract
A device for independent hydraulic actuation of phase and axial positions of a camshaft of an internal combustion engine with a phase adjuster and an actuating piston arranged on a common axis for axial displacement of the camshaft. In order to reduce the space needed and construction expenditure of the device, the phase adjuster also acts as the actuating piston for the camshaft.
