Abstract:
A variable valve timing controller for an internal combustion engine, the variable valve timing controller being disposed in a system in which the torque of a driving shaft is transmitted to a driven shaft adjusting an opening and closing timing of an intake valve and/or an exhaust valves, comprising:a rotary shaft connected with a driving shaft; a stator applying a torque to the rotary shaft by generating a magnetic field around the rotary shaft, the stator fixed relatively to the internal combustion engine; and a rotational phase converter converting the rotational phase of the driven shaft relatively to the driving shaft; wherein when the stator stops forming the electro magnetic field, the load torque arises on rotary shaft, and the rotational phase converter converts the rotational phase of the driven shaft toward a feasible phase in a safety direction with receiving the load torque, the feasible phase in which the internal combustion engine can be started.
