A hydraulic device for adjusting the rotation angle of a camshaft relative to a crankshaft in an internal combustion engine. The device has a rotor, with blades arranged around its periphery. A stator is connected in a rotationally secure manner to a drive wheel. The rotor and the stator together form pressure chambers, which can be filled with hydraulic fluid via a hydraulic fluid system, in which there is disposed a volume accumulator.
