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 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： In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.

摘要： A valve timing adjusting device includes: a first rotary body which rotates in synchronization with one of a crankshaft and a camshaft and into which lubricating fluid is supplied; a second rotary body which rotates in synchronization with the other; a torque producing unit for producing control torque; and a phase change unit including a planetary gear mechanism in which a planetary gear is engaged with a sun gear in such a way as to be able to perform a planetary motion. The phase change unit changes a relative rotational phase between the first rotary body and the second rotary body by utilizing the control torque transmitted from the torque producing unit to the planetary gear mechanism and has a space at an interface where the first rotary body is brought into sliding contact with the planetary gear.

摘要： A valve controller includes a detector detecting a shutdown command signal to shutdown an engine, a driving circuit for driving a motor, and a power source controller. The power source controller turns on the driving circuit until the predetermined period has passed since the shutdown command signal is detected. Thus, the valve controller adjusts the valve opening/closing character in such a manner as to be suitable to an engine condition.

摘要： An internal planetary gear mechanism reduces a load applied to tooth surfaces of an external gear and an internal gear, a sliding portion such as a bearing and the like. By setting the amount of eccentricity α of an eccentric part to be larger than a theoretical value, a distance between the center of the external gear and the center of the internal gear is increased to allow the reduction of a loss in the bearing and on the tooth surfaces of the gears, and a mesh zone between the internal gear and the external gear can be reduced to decrease a part at a large pressure angle, thereby reducing a loss generated by a large pressure angle. As a result of reduction in the mesh zone between the external gear and the internal gear, rolling contact of the gears is maintained.
