摘要:
Provided is a valve timing control apparatus configured to realize a locked state before an engine is stopped by controlling a restricting mechanism and a locking mechanism while the engine is operating. The apparatus includes a partitioning section provided in a driven-side rotary member for partitioning between an advanced angle chamber and a retarded angle chamber, a restricting member disposed in the driven-side rotary member and capable of projecting/retracting relative to a driving-side rotary member, a restricting recess portion formed in the driving-side rotary member and receiving the restricting member projected therein for restricting a relative rotational phase within a predetermined range, a locking member disposed in the driven-side rotary member and capable of projecting/retracting relative to the driving-side rotary member, a locking recess portion receiving the locking member projected therein for locking the relative rotational phase to a predetermined phase, and a communication passageway capable of feeding fluid releasing the restriction by the restricting member to the locking member and incapable of feeding fluid releasing the locking by the locking member to the restricting member. The restricting member switches over the communication passageway to a communicating state or to a non-communicating state.
