摘要： In an oil flow control valve (OCV) according to the present invention, a first volume varying chamber is adapted to communicate with a second volume varying chamber through a second plunger breathing path, and the second volume varying chamber is adapted to communicate with a first breathing hole through an intra-plunger breathing path, an intra-shaft breathing path, and a third volume varying chamber. That is, the breathing path to the second volume varying chamber is long and the volume thereof is large, and the breathing path to the first volume varying chamber is still longer and larger in its volume. Consequently, the amount of foreign matters getting into the first and second volume varying chambers can be decreased and therefore it is possible to prevent the occurrence of an operation defect of the OCV.

摘要： At an initial drive operation after turning on of an electric power source, an ECU sequentially changes each current exciting phase among multiple phases through one complete cycle at a predetermined time schedule, so that a rotational position of a rotor and the corresponding exciting phase coincide with each other at some timing during the initial drive operation, and thereby the rotor is rotated. The ECU counts the A-phase signal and the B-phase signal during the rotation of the rotor in the initial drive operation and learns a relationship among a count value of the A-phase signal and the B-phase signal, a rotational position of the rotor and each exciting one of the plurality of phases at an end of the initial drive operation. When the ECU determines that a result of the learning is erroneous, the ECU re-executes the learning by re-executing the initial drive operation.

摘要： A P-range side delimiting position of a movable range of a range change mechanism is learned by rotating a motor to a corresponding rotational position, which corresponds to the P-range side delimiting position. A climb correction amount is set for a learning value of the P-range side delimiting position to correct the learning value of the P-range side delimiting position in view of presence of a relatively small angle of rotation of the motor beyond the corresponding rotational position, which corresponds to the P-range side delimiting position. The climb correction amount is set according to motor temperature information, which is one of a temperature of the motor and a temperature that relates to the temperature of the motor.

摘要： In a valve timing adjusting apparatus, an outer peripheral surface of each projection of an internal gear, which is received in a corresponding engaging hole of a guide rotator, may have reduced surface sections, which are radially inwardly reduced toward a radial center of the projection along a radial line of the internal gear that passes through the radial center of the projection to have a reduced radial size in comparison to a radial size of the rest of the outer peripheral surface of the projection. Alternatively, an inner peripheral surface of each engaging hole may have recessed surface sections, which are radially recessed from the rest of the inner peripheral surface of the engaging hole along a radial line of the guide rotator that passes through a center of the inner peripheral surface of the engaging hole.

摘要： A feed position of oil from an oil pump is changed to improve the machinability of an engine cylinder block. A plunger guide is obtained which attains improvement in pump pressure resistance and retention of magnetic efficiency. An oil feed port connected to an oil feed path on the oil pump side is formed in a front end face of a sleeve in an electromagnetic type oil control valve, while a drain port connected to an oil discharge path on a drain side is formed in a side face of the sleeve, whereby an oil feed path formed in the engine cylinder block is positioned coaxially with a mounting hole of the electromagnetic type oil control valve. Further, a bottom wall portion of the plunger guide is curved so that the pump pressure resistance can be improved without increasing the plate thickness of the plunger guide.

摘要： A shift-by-wire shift switching device and shift switching method that switch a shift range of an automatic transmission using an electric motor. The shift switching device includes a controller that determines whether a fault has occurred in a current supply line of each phase of the electric motor on a phase-by-phase basis, executes an open-loop control of the electric motor using only the phases in which it has been determined that a fault has not occurred, and determines whether a fault has occurred in the current supply line by detecting an activation state of the electric motor when the open-loop control of the electric motor is executed. Therefore, it is possible to determine whether a fault in the motor is a short-circuit fault or a break fault, without addition of a part such as a short-circuit detection sensor.

摘要： A controlling device includes a range switch mechanism, range switch operating means, operation frequency monitoring means, and heat generation limit controlling means. The range switch mechanism is adapted to change a shift range using a motor. Through the range switch operating means, an occupant inputs a required shift range. The motor is controlled in accordance with the required shift range such that the shift range is changed into the required shift range. The operation frequency monitoring means monitors an operation frequency of the range switch operating means. The heat generation limit controlling means switches a control of the motor to a heat generation limit control when the operation frequency of the range switch operating means exceeds a predetermined frequency.
