Abstract

A hydraulic camshaft adjustment device (1) of the vane type, with a stator (2) and a rotor (3) arranged concentrically and rotatably inside the stator is provided. A locking device (6) for preventing a rotation between the rotor (3) and the stator (2) is arranged between these two components (2, 3) such that a locking element (7) of the locking device (6) creates an interlocking fit that blocks the rotation, the locking element (7) being designed in the nature of a plate.
