摘要:
A valve timing control apparatus includes a phase holding mechanism for holding relative phase between an inner peripheral member and an outer peripheral member to a predetermined intermediate phase between a most advanced angle phase and a most retarded angle phase, a fluid feeding device for feeding fluid to an advanced angle chamber or a retarded angle chamber through a first fluid passageway or a second fluid passageway, and a fluid control valve for switching over the passage for the fluid discharged from the fluid feeding device to either the first fluid passageway or the second fluid passageway and controlling the feeding amount of the fluid. The phase holding mechanism is configured to have its holding state for holding the relative phase released by a fluid pressure of the first fluid passageway or the second fluid passageway to whichever the fluid control valve starts the feeding of the fluid. After releasing of the holding state of the relative phase, this releasing state is maintained by a fluid pressure applied thereto from at least one of the first fluid passageway and the second fluid passageway.
