摘要:
A valve timing control apparatus includes an inner rotor, a vane, an outer rotor, a first fluid passage to an advanced angle chamber, a second fluid passage to a retarded angle chamber, a lock mechanism restricting the relative rotation between the inner and outer rotors, a third fluid passage establishing an unlocked state by supplying the fluid to the lock mechanism and a locked state by discharging the fluid from the lock mechanism, a first switching valve supplying the fluid to each of the first and second fluid passages and discharging from each of the first and second fluid passages and a second switching valve controlling a fluid flow to be supplied to or discharged from the third fluid passage, wherein the first switching valve is operated independently from the second switching valve, and the fluid is supplied to the first switching valve via the second switching valve.
