Abstract:
A camshaft adjuster ( 1 ) is provided, including a drive element ( 2 ) and a driven element ( 3 ), which can be rotated in relation to the drive element within an angular range and can be connected to a camshaft, wherein pressurizable working chambers ( 4 ) for rotating the drive element ( 2 ) with respect to the driven element ( 3 ) are formed between the drive element ( 2 ) and the driven element ( 3 ), wherein the camshaft adjuster ( 1 ) has a volume accumulator ( 5 ) for collecting hydraulic medium, wherein the volume accumulator ( 5 ) supplies the hydraulic medium to a vacuum-pressurized working chamber ( 4 ) via a check valve ( 6 ) in that the vacuum in the working chamber ( 4 ) opens the check valve ( 6 ), characterized in that the check valve ( 6 ) is arranged in an axial position between the working chamber ( 4 ) and the volume accumulator ( 5 ), and the volume accumulator ( 5 ) is formed by a cover element ( 7 ) connected to the drive element ( 2 ) for conjoint rotation.

Claim (Index 1):
A camshaft adjuster comprising: a drive element, a driven element that is rotatable relative to the drive element within an angular range and is adapted to be connected to a camshaft, work chambers that are pressurizable located between the drive element and the driven element, the work chambers are formed for rotating the drive element relative to the driven element, a volume accumulator adapted to collect hydraulic medium, a check valve located in each of the work chambers, the volume accumulator feeds the hydraulic medium via the check valve of a vacuum-pressurized one of the work chambers via vacuum pressure in the work chamber opening the check valve, each of the check valves is arranged in an axial position between the work chamber and the volume accumulator, and the volume accumulator is formed by a cover element locked in rotation with the drive element.
