Abstract: A valve timing control device includes a lock mechanism having a hole portion formed in one of the driving-side/driven-side rotational members, a sleeve in the hole portion, a lock member in the sleeve and capable of projecting and retracting with respect to the other of the driving-side/driven-side members, and a lock hole formed in the other of the driving-side/driven-side members such that the lock member can be fitted to the lock hole when the lock member projects. The lock mechanism constrains a relative rotational phase of the driven-side rotational member with respect to the driving-side rotational member at a predetermined phase when the lock member is fitted to the lock hole. A first chamfered surface is formed in the circumferential direction at an inner-circumferential corner of an end of the sleeve on the side opposite to the side facing the lock hole.

The invention includes: a first component which is rigidly connected to the camshaft of the engine, such that the rotation of the first component causes the camshaft to rotate; a second component which is rotated by the crankshaft of the engine; a third component which connects the first and second components to one another and which, in turn, rotates the first component in relation to the second component in order to vary the position and partial speed of the camshaft in respect of the crankshaft; and a fourth component which is used to impart a longitudinal and reciprocating longitudinal movement to the third component. The purpose of the device is to enable the opening and closing time and duration of the valves to be varied by varying the position and partial speed of the camshaft in relation to the crankshaft.

Abstract: A synchronous drive apparatus includes first and a second rotors. The rotors have multiple teeth for engaging sections of an elongate drive structure. A rotary load assembly couples to the second rotor. The elongate drive structure engages about the rotors. The first rotor drives and the second rotor is 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 presents a periodic fluctuating load torque when driven in rotation. 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 cancels the fluctuating load torque of the rotary load assembly.

Abstract: A valve timing adjusting apparatus adjusts valve timing of at least one of intake and exhaust valves of an engine that are opened and closed by a camshaft driven by torque transmitted from a crankshaft. The apparatus includes an electric motor, a plurality of switching elements, a motor driver, and a phase adjusting mechanism. When a target rotational direction of a motor shaft of the electric motor is coincident with the actual rotational direction of the same, the motor driver continuously turns on a selected one of the switching elements for the whole of a predetermined rotation angle range of the motor shaft. When the target rotational direction is opposite to the actual rotational direction, the motor driver continuously turns on the selected switching element only for part of the rotation angle range, and continuously turns off the selected switching element for the remaining part of the rotation angle range.
