摘要： A system for relative angle-of-rotation adjustment of a camshaft of an internal-combustion engine. An adjusting unit has an interior part connected with the camshaft, and a cell wheel with several cells distributed along the circumference. Interior part webs divide the cells into two pressure spaces. Hydraulic pressure admitted or relieved from the pressure spaces causes camshaft rotation between two end positions. A movable locking element in the cell wheel or the interior part opens up a hydraulic line to a pressure space when in an unlocked position. When in a locked position, bores in the interior part are closed off. The locking element can move into first and second unlocking positions, whereby the various bores are opened at desired intervals as the locking element moves. As a result, the useful life and the functionality of the locking device is improved.
