摘要:
A variable valve timing control apparatus includes a driving rotor, a driven rotor coaxially arranged with the driving rotor, a fluid pressure chamber defined between the driving rotor and the driven rotor, a partition portion arranged at one of the driving rotor and the driven rotor and dividing the fluid pressure chamber into advanced and retarded angle chambers, a first fluid control mechanism controlling supply and discharge of a hydraulic fluid to and from the fluid pressure chamber, a first phase restriction portion restricting and releasing a relative rotational phase between the driving rotor and the driven rotor within and from a first restriction range, a second phase restriction portion restricting and releasing the relative rotational phase within and from a second restriction range, and a second fluid control mechanism controlling the supply and discharge of the hydraulic fluid to and from the first and second phase restriction portions individually.
