摘要： A valve timing adjuster for an internal combustion engine adjusts valve timing. The valve timing adjuster includes a housing, a vane rotor, a regulation device, a fluid route, and an opening/closing control device. The regulation device regulates a rotational phase of the vane rotor relative to the housing to a regulation position located between a full advance position and a full retard position. The fluid route is communicated with a specific chamber that is at least one of an advance chamber and a retard chamber. The fluid route extends via a radially inner part to be communicated with atmosphere. The radially inner part is located radially between the specific chamber and a rotation center. The opening/closing control device opens and closes the fluid route.

摘要： 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.

摘要： A vane rotor includes a vane to partition an advance chamber from a retard chamber. A valve element communicates a lock port with an exhaust port to drain a fluid from the lock port when moving in a first region including an end of a movable range in the first direction. The regulating member moves in the vane rotor in a thrust direction into a recess dented from an inner surface of the housing by being biased from a resilient member to lock the rotation phase in a regulation phase in the first region when a fluid is drained from the lock chamber. The valve element is configured to communicate an operation port with a supply port to supply a fluid into the advance chamber when being in a throttle region in the first region such that a flow of a fluid supplied to the advance chamber is throttled to be less than a flow of a fluid when the valve element is in the end of the movable range in the first direction.

摘要： A voltage conversion apparatus includes a booster circuit, a boost stop circuit, a Zener diode, and a capacitor. The boost stop circuit includes a transistor. When an overvoltage equal to or larger than a breakdown voltage of the Zener diode is output to an output line of the booster circuit, the Zener diode is turned on. Accordingly, the transistor is turned on and a switching element is turned off to stop a boost operation. Further, the capacitor is charged through the Zener diode. Even when the Zener diode is turned off due to a drop in the output voltage after the stop of the boost operation, the transistor maintains its on state for a certain time by discharge of the capacitor. Thus, the stop of the boost operation is continued.
