摘要： 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.

摘要： In a valve timing controller, the guide-groove biases the moving element in a direction in which the moving element slides with respect to a radial line connecting a center of the guide-rotational element and the moving element, when the guide-rotational element relatively rotates with respect to the first rotational element. The direction in which the moving elements are pushed and the direction in which the moving elements moves are substantially identical to each other.

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 spark plug for an internal combustion engine is provided which is equipped with a tip protrusion disposed on a top of a hollow cylindrical housing of the spark plug. The spark plug also includes a center electrode retained in a porcelain insulator disposed inside the housing and a ground electrode is joined to the housing so as to form a spark gap. The tip protrusion serves to direct a flow of gas to be ignited by a spark produced in the spark gap and is shaped to have a radial width extending in a radial direction of the housing and a circumferential width extending in a circumferential direction of the cylindrical housing. The radial width is greater than the circumferential width. This enhances the efficiency in guiding the flow of gas toward the spark gap.

The stopper surface is engageable with a cylindrical outer peripheral surface of a movable body, which is received in the guide groove, to stop the movable body. An arcuate outer connection surface connects between the stopper surface and an outer guide surface and has a radius of curvature, which is smaller than that of the cylindrical outer peripheral surface of the movable body. An arcuate inner connection surface connects between the stopper surface and an inner guide surface and has a radius of curvature, which is smaller than that of the cylindrical outer peripheral surface of the movable body.
