摘要： A valve opening and closing timing control device includes a vane selectively moving a relative rotational phase of a driven-side rotary member relative to a driving-side rotary member between a retarded direction and an advance direction, an intermediate lock mechanism being switchable between a lock state and an unlock state, and a phase control portion performing a control of a supply of a fluid to a retard chamber and a discharge of the fluid from an advance chamber, or a control of a discharge of the fluid from the retard chamber and a supply of the fluid to the advance chamber, in order for a lock member to reach an intermediate locked phase by reducing a travelling speed of the relative rotational phase from a reference phase to the intermediate locked phase to be slower than the travelling speed of the relative rotational phase to the reference phase.

摘要： A system for controlling valve opening/closing timing that allows an unlocking operation to be reliably performed is configured. When extracting a lock member from a recess, a second control valve is set to an unlock position, a first control valve is set to a predetermined position, and a relative rotation phase is displaced. As a result, the relative rotation phase is displaced in a direction opposite to the direction of displacement by cam average torque from a camshaft. Afterward, by setting the first control valve to a neutral position, the relative rotation phase is displaced by the cam average torque, and when this displacement occurs, a state in which the lock member is separated from an inner wall of the recess is created, thus facilitating extraction of the lock member from the recess.
