Abstract:
Assembly for a relative angle-of-rotation adjustment of a camshaft of an internal-combustion engine with respect to a driving wheel, comprising:an interior part which is non-rotatably connected with the camshaft and which has at least approximately radially extending blades, a driven cell wheel which has cells which are distributed along a circumference, are bounded by webs and can be divided into two pressure spaces by the blades guided in the cells in an angularly movable manner, during the admission or discharge of hydraulic pressure to or from the pressure spaces by way of control lines, the camshaft being rotatable by way of the blades between two end positions relative to the cell wheel, and at least one locking device which is operative between the interior part and the cell wheel, thereby the interior part can be locked with respect to the cell wheel in at least one of the end positions, wherein at least one of the blades of the interior part has a head part having at least one locking element which interacts with a locking structure of the cell wheel and is changeable as a function of operating parameters from a locked position into an unlocked position, and wherein the locking structure is arranged on at least one of the webs of the cell wheel.
