    Abstract: A device for varying valve timing in an internal combustion engine comprises an adjusting mechanism for varying an angle of rotation between a drive pinion (2) and a camshaft (end portion of the camshaft 1), said adjusting mechanism being configured as a wobble transmission. The drive pinion (2) comprises a first front-end gearing (9) and a disk (10) comprises a second front-end gearing (11), which first and second front-end gearings mesh partially with each other, and the number of teeth of said front-end gearings differ from each other by at least one tooth. To reduce the overall dimensions of the device and avoid gearing lash, it is proposed, on the one hand, to connect the disk (10) rotationally fast to the camshaft (1) and on the other hand, to configure the disk (10) in axial direction of the camshaft (1) as a flexible element that can be deformed in axial direction by an adjusting device (thrust plate 17).

    Abstract: A synchronous drive apparatus and method, wherein the apparatus comprises a plurality of rotors comprising at least a first and a second rotor. The first rotor has a plurality of teeth for engaging the engaging sections of an elongate drive structure, and the second rotor has a plurality of teeth for engaging the engaging section of the elongate drive structure. A rotary load assembly is coupled to the second rotor. The elongate drive structure engages about the first and second rotors. The first rotor is arranged to drive the elongate drive structure and the second rotor is arranged to be driven by the elongate drive structure. One of the rotors has a non-circular profile having at least two protruding portions alternating with receding portions. The rotary load assembly is such as to present a periodic fluctuating load torque when driven in rotation, in which the angular positions of the protruding and receding portions of the non-circular profile relative to the angular position of the second rotor, and the magnitude of the eccentricity of the non-circular profile, are such that the non-circular profile applies to the second rotor an opposing fluctuating corrective torque which reduces or substantially cancels the fluctuating load torque of the rotary load assembly.

    Abstract: A variable valve mechanism using a non-uniform coupling in an internal combustion engine is equipped with an axis-supporting member for supporting a cam-side rotation axis in an eccentric state. In the variable valve mechanism, the axis-supporting member is driven while taking account of friction occurring in the axis-supporting member by changing the position of the axis-supporting member so as to align with the direction of a dragging torque generated between the axis-supporting member and an intermediate rotating member or between the axis-supporting member and a rotation axis member.

    Abstract: An object of the present invention is to obtain a controller device for a variable valve timing apparatus capable of controlling a phase to an arbitrary fixed valve timing from immediately before an internal combustion engine stops until after the internal combustion engine has stopped. The controller device for the variable valve timing apparatus according to the present invention performs, during engine stop processing of the internal combustion engine, normal control of changing the relative rotational phase of a camshaft to a most advanced position or a most retarded position when the rotational speed of a crankshaft is equal to or more than a first threshold, and low-speed control of fixing a current or a voltage supplied to the motor to be constant to maintain the relative rotational phase of the camshaft at the most advanced position or the most retarded position in a period from when the rotational speed of the crankshaft is lower than the first threshold until the rotational speed becomes zero.
