摘要:
A valve timing control device is switchable between a first state in which a fluid is supplied to a communication flow path to lift a restriction by a restriction member and release a lock by a lock member, a second state in which the fluid is supplied to a retarded angle chamber to release the lock by the lock member and set the restriction by the restriction member, and a third state in which the restriction member is restricted and the lock member is locked without supplying the fluid to the communication flow path and supplying the fluid to the retarded angle chamber, and is configured such that the minimum cross-sectional area of an advanced passage for supplying the fluid to an advanced chamber is greater than the minimum cross-sectional area of a retarded passage for supplying the fluid to the retarded angle chamber.
