Abstract:
1. A camshaft adjustment device for an internal combustion engine of a motor vehicle, comprising a drive part formed as an outer stator, and a driven part formed as an inner rotor, the driven part is supported for rotation relative to the drive part between a first angular position and a second angular position, a separate insert part originating from the drive part or the driven part is further arranged in a rotational angle limiting connecting link that is formed in the drive part or the driven part, the insert part is arranged to be brought into blocking contact with two blocking elements that are moveable in an axial direction, the insert part includes two opposite ends each having a concave recess that is adapted to an outer convex contour on a respective one of the two blocking elements, and a pitch circle extending through centers of the two blocking elements intersects each concave recess on the opposite ends of the insert part, wherein the insert part locks the driven part in a middle position between the first angular position and the second angular position, coming into contact at two points located at two opposing ends of the insert part, each with one of the blocking elements, by a positive-fit connection, and the blocking elements are in connection with at least one of springs or oil control channels.
