Abstract (en)
[origin: EP1607590A2] The device includes a hydraulic fluid system with at least one hydraulic valve and connected to two pressure chambers (12,13) pressurized or depressurized with hydraulic fluid though hydraulic lines. The two pressure chambers are separated within the work spaces (9) of a drive wheel (3) by the blades (11) of a rotor (5). The rotor is rotatable relative to a stator (4), and attached to the camshaft. The drive wheel couples the stator to the crankshaft.
