Abstract: A control device has two modes as control modes of an electric power supply to an electromagnetic solenoid, which are used when a first determining unit determines that a difference between a sensed value of a phase and a target value of the phase exceeds a permissible range. One of the modes is a special mode that is used when a second determining unit determines that the sensed value of the phase reaches a threshold value. Another one of the modes is a normal mode that is used when the second determining unit determines that the sensed value of the phase does not reach the threshold value. In the special mode, the control device controls supply of the electric power to the electromagnetic solenoid in such a manner that an opening degree of an advancing port is larger than the opening degree of the advancing port in the normal mode.

Abstract: An oil control valve has a housing and a spool valve that is arranged in the housing and is movable in the axial direction. The movement range of the spool valve includes a first area and a second area. In the first area, a port that is connected to a lock mechanism opens to prevent the movement of a variable valve timing mechanism through drainage of oil from the lock mechanism. In the second area, oil is supplied and drained to and from the variable valve timing mechanism through a passage inside the spool valve. The first area exists at a position separated from the second area in the movement range.

Abstract: 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.

Abstract: A variable valve timing apparatus includes a stopper piston which has an equalizing passage in an axial direction. Even if the engaging hole is filled with the oil, the equalizing passage enables the oil flows from an engaging hole to a holding hole when the stopper piston enters into the engaging hole. It is possible to form a vane as narrow as possible, and to enlarge a variable angular range. In addition, the stopper piston has both end faces which are substantially identical in surface area. Even if pulsation arises in oil pressure, pressures acting on both end faces of the stopper piston can be substantially cancelled and position of the stopper piston can be stabilized.
