Abstract

An arrangement for the relative angle-of-rotation adjustment of a camshaft with respect to a driving wheel has an interior part which is non-rotatably connected with the camshaft. A driven cell wheel has several cells which are distributed along the circumference and are bounded by webs and can be divided into two pressure spaces by the webs or blades guided therein in an angularly movable manner. At least one locking device, which is operative between the interior part and the cell wheel, can lock the interior part with respect to the cell wheel in at least one end position. At least one blade of the interior part has a head part having at least one locking element which interacts with a locking structure provided on at least one web of the cell wheel.
