Abstract:
Device for hydraulic rotational angle adjustment of a camshaft to a drive wheel in an internal combustion engine, comprising:an inner part that is nonrotatably connected with the camshaft, said inner part having radially extending ribs or vanes, anda driven compartmented wheel that has a plurality of compartments distributed around the circumference which are subdivided by the ribs or vanes guided in an angularly movable fashion, into two pressure chambers each, for whose pressurization the inner part is rotated relative to the compartmented wheel, and with means for securing the rotational position of the inner part relative to the compartmented wheel,wherein the means for securing the rotational position constitutes an annular piston that cooperates with at least one axial end face of the ribs or vanes of the compartmented wheel.
