Abstract: 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.

Abstract: 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 ? 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.

Abstract: A valve timing adjusting device adjusts valve timing by shifting rotational phase of a camshaft relative to a crankshaft. The device has an electric motor for rotating a rotor member that drives and moves a phase defining member to a required position. The phase defining member defines the rotational phase of the camshaft in accordance with the position itself. The phase defining member may be a planetary gear rotatably supported on an eccentric shaft as the rotor member. The planetary gear works as both a reduction mechanism and a phase shifting mechanism. The phase defining member may be a control pin slidably supported on a rotatable member as the rotor member. A planetary gear may be additionally used as the reduction mechanism for rotating the rotatable member. It is possible to control the phase with high accuracy and durability.

Abstract: A valve timing adjusting device sets an amount of phase shift of a driven shaft with respect to a drive shaft. A first hole in a first rotor forms a first track extending in order to vary its radial distance from a rotation center line. The first hole makes contact with a control member passing through the first track, on the two sides of the first hole toward which the first hole (the first rotor) rotates. A second hole in a second rotor forms a second track that extends. The second hole makes contact with the control member that passes through the second track. The first track and the second track slant toward each other in the rotation direction of the first and second rotor.

Abstract: The variable valve timing controller controls the valve timing of the intake valve. The variable valve timing controller has a shaft, the stator fixed on the engine and generating the magnetic field around the shaft and rotational phase converter converting the torque applied to the shaft. When the valve timing is in the most delayed timing, the engine can be started. The rotational phase of this timing is called the feasible phase. When the stator stops generating the magnetic field, the load torque arise on the shaft. The rotational phase converter varies the rotational phase into the feasible phase with receiving the load torque from the shaft.
