摘要： 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 hydraulic accumulator, which differs from the oil pump and the supply line.

摘要： A camshaft adjusting device for an internal combustion engine including: a vane-type adjuster actuable by a pressure medium and which is rotationally fixed to a camshaft by a rotor and rotationally fixed to a crankshaft by a stator; a central valve has a displaceable valve body, by which a pressure medium is fed to the vane-type adjuster via a pump from a reservoir, the medium being selectively introduced into different working chambers and fed back from other working chambers to the reservoir, depending on the position of the valve body. The device includes a rolling bearing, by which the end section of the camshaft facing the vane-type adjuster is mounted in relation to a fixed housing wall. An axially oriented through-flow opening extends through the rolling bearing through which the pressure medium delivered by the pressure flows in an axial direction to the central valve.
