ABSTRACT:
A valve timing control apparatus for controlling an opening and closing timing of a valve of an internal combustion engine includes a driving side rotational member synchronously rotated with a crankshaft, a driven side rotational member provided coaxially with the driving side rotational member and synchronously rotated with a camshaft, a fluid pressure chamber being separated into an advanced angle chamber and a retarded angle chamber, a phase control apparatus for displacing a relative rotational phase between the driving side rotational member and the driven side rotational member, a locking mechanism having a movable member, a judging device for judging a supply condition of the operation fluid relative to the fluid pressure chamber, and a control device for controlling a rotational speed of the crankshaft.
