Internal combustion engine with a hydraulic cam phaser having a stator made of sheet metal

The device has a rotor (6) with blades (10) fixed to the camshaft (2), and a stator (4) with end wall (5), fixed to a drive pulley (3) driven by the camshaft. Stator and end wall are formed as a one-piece metal plate part (19) produced by a non-cutting process, e.g. deep-drawing. Starting from the end wall, segments of the stator are offset in axial direction, so that pressure chambers are formed between an end wall section and web walls on one side of an outer wall (8), and segment-like cutouts are formed on the other side of an inner wall. The pressure chambers are closed by a sealing plate (14), or by plastic injected onto the end wall.
