摘要： A rotational angle sensor and a hydraulic pressure control valve are disposed such that a detecting end surface of the rotational angle sensor disposed close to a sensor rotor attached to an exhaust camshaft is located in a spray area of return oil discharged through a drain hole formed at a cam cap, which flows down through a lower drain port of the hydraulic pressure control valve attached on the cam cap from a variable valve timing mechanism. Further, the detecting end surface is located forward in the rotational direction, shown as the arrow a, of the exhaust camshaft so that the return oil can be positively carried toward the detecting end surface by the rotation of the sensor rotor. Accordingly, this can maintain properly detecting accuracy of the rotational sensor disposed close to the camshaft.

摘要： An intake valve or an exhaust valve is lifted through a swingable cam by the rotation of a rotatable cam formed in the cam shaft. A surface at which the swingable cam abuts with the rotatable cam is tapered in the axial direction in which said cam shaft extends, and the valve shift timing is changed by transferring the cam shaft, that is, the rotatable cam in the axial direction in which said cam shaft extends. The power transmitting member such as a helical gear to be rotated with the output shaft of the engine is engaged with the cam shaft through a helical spline. The power transmitting member is so arranged as to be unmovable in the axial direction in which said cam shaft extends. The rotational phase of the rotatable cam relative to the output shaft of the engine is changed by displacement of the cam shaft relative to the power transmitting member in the axial direction in which said cam shaft extends.

摘要： An internal combustion engine is equipped with a valve timing controller capable of minimizing the electric power consumption and frictional wear of elements. The valve timing controller can vary the valve timing of valves. A camshaft is moved axially forwardly or rearwardly by electrically energizing an outer solenoid clutch or a brake releasing solenoid, respectively. An axial movement of the camshaft results in a change in valve timing. With the exception of a transient period during which the valve timing is being varied, both the brake releasing solenoid and the outer clutch are electrically deenergized to thereby reduce the electric power consumption, and both of them are maintained out of contact with a displaceable disc 13 to thereby reduce frictional wear thereof.
