摘要： A rotational position detecting apparatus for an internal combustion engine comprises a first and a second signal generator each thereof having a signal rotor rotating in synchronism with the rotation of the engine, a first and a second waveform reshaping circuit and a signal processing circuit. Engine rotational angle signals produced by the first signal generator and engine cylinder reference angular position signals and a specified cylinder angular position signal produced by the second signal generator are reshaped through the first and second waveform reshaping circuits, respectively, and both output signals from the first and second waveform reshaping circuits are supplied to the signal processing circuit. The signal processing circuit separates the reference signals and the cylinder discrimination signal from the output signals of the second waveform reshaping circuit and outputs the separated signals along with the angle signals produced by the first waveform reshaping circuit.This rotational position detecting apparatus for internal combustion engines is featured in that it is simple in construction and small in size and its operation is hardly susceptible to interference caused by radio noise.

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： 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 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.

摘要： A valve timing adjustment device for promptly switching a rotational phase includes a guide rotary body having a guide passage containing a movable body. The guide passage includes a variable radial dimension relative to a rotational centerline. The guide rotary body rotates relative to a driving rotary body and guides the movable body in the guide passage. A phase change mechanism changes the rotational phase of a driven shaft relative to a drive shaft according to the position of the movable body in the guide passage. The guide passage has a gradually decreasing region and a gradually increasing region. The gradually decreasing region slants toward an axis of the guide rotary body. The gradually increasing region slants relative toward the axis of the guide rotary body. The gradually decreasing region and the gradually increasing region are connected.

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.
