摘要： A valve opening/closing timing control device includes: an intermediate lock mechanism switchable between a locked state constraining a relative rotation phase to an intermediate locked phase, and an unlocked state releasing the constraint; a phase control unit controlling fluid supply to a retard chamber and fluid discharge from an advance chamber, or controlling fluid discharge from the retard chamber and fluid supply to the advance chamber, such that the lock member attains the intermediate locked phase; and a determination unit determining whether the lock member will attain the determination phase, when control has been performed to move the lock member toward a determination phase that has been set at a different position than the intermediate locked phase, after execution of control to either supply fluid to the retard chamber and discharge fluid from the advance chamber, or discharge fluid from the retard chamber and supply fluid to the advance chamber.

摘要： Provided is a valve timing controller capable of quickening a response in varying a relative rotational phase. When the valve timing controller is under a locking state, if an ECU outputs a phase maintenance signal indicative of a phase maintaining state wherein control for maintaining the relative rotational phase within a predetermined range by work fluid present in an advancing chamber and a retarding chamber is possible, an intermediate locking mechanism is switched to a lock-releasing state and also the relative rotational phase is maintained to an intermediate locking state.

摘要： A valve opening/closing timing control device includes a driving rotating body that rotates in synchronization with a crankshaft, a driven rotating body that rotates integrally with a camshaft, a phase detection mechanism that detects the relative rotation phase of the driving rotating body and the driven rotating body, a retarding chamber and an advancing chamber between the driving rotating body and the driven rotating body, a lock mechanism capable of constraining the relative rotation phase to a lock phase, a supply/discharge mechanism that supplies/discharges working fluid to/from the advancing chamber, the retarding chamber, and the lock mechanism, and a control unit that controls operation of the supply/discharge mechanism. At startup of the engine, if the detected relative rotation phase is not at the lock phase, the control unit controls the supply/discharge mechanism so as to stop successive supply of working fluid to the retarding and advancing chambers.

摘要： The valve open/close timing control device includes a housing that rotates synchronously with a crankshaft, an inner rotor that is disposed inside of the housing and rotates integrally with a camshaft, a fluid pressure chamber formed between the housing and the inner rotor, an intermediate lock mechanism capable of switching between a locked state and an unlocked state, an unlocking channel that allows passage of working oil to be supplied to or discharged from the intermediate lock mechanism, a lock discharge channel that allows passage of working oil discharged from the intermediate lock mechanism, and an electromagnetic valve that controls the supply/discharge of the working oil to/from the fluid pressure chamber and the intermediate lock mechanism. With this valve open/close timing control device, the lock discharge channel allows passage of the working oil in the case where the electricity supply amount to the electromagnetic valve is 0 or the maximum.
