Abstract
A camshaft adjuster including a stator, a rotor and a pressure medium supply, at least one chamber being formed on the stator, which is divided into two working chambers by at least one vane formed on the rotor or rotatably fixedly connected to the rotor is provided. A pressure medium is applicable to each of the two working chambers via the pressure medium supply in such a way that a pressure of the pressure medium may be increased in each of the working chambers to the extent that the pressure increase results in a rotation of the rotor. A switchable valve is formed in the vane of the rotor, which, in a first switching position of the valve, allows a flow of the pressure medium from a first working chamber through the vane into a second working chamber, in a second switching position the valve hydraulically separating the working chambers from each other. A locking element, which fixes the vane in a defined position with respect to the chamber, is designed to control an inflow or outflow of the pressure medium into or out of a working chamber. The pressure medium supply includes an oil pump, a supply line connecting the oil pump to at least one of the working chambers and a hydra…
