摘要

The device (1) has a drive element (3) that is propelled by a crank shaft, where the drive element is supported opposite to a camshaft (2) in a rotating manner. Two hydraulic chambers (4,5) are formed between the drive element and the camshaft. A pump (6) is integrated in a piston element (7) which is arranged in the drive element in a relocatable manner.
