Abstract: A synchronous drive apparatus includes first and a second rotors. The rotors have multiple teeth for engaging 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: In a variable valve timing mechanism, a valve-lifting cam member is fitted, slidably in the circumferential direction, onto a camshaft that is driven to rotate in synchronization with a crankshaft of a four-stroke cycle internal combustion engine. An eccentric collar is set between a driving collar fixed on the camshaft and the valve-lifting cam member. A driving projection is formed in the driving collar and engages with one of sandwiching portions of the eccentric collar. A driven protrusion is formed in the valve-lifting cam member and engages with another one of the sandwiching portions of the eccentric collar. A linkage mechanism includes the eccentric collar, the drive, and the driven protrusions. The variable valve timing mechanism adjusts the timing of opening and closing of the valve while the rotational phase of the valve-lifting cam member is cyclically varied relative to the camshaft by the eccentricity of the eccentric collar.

Abstract: The invention provides a phase variable device for use with a car engine, capable of preventing the phase angle of the camshaft from varying relative to the first circular rotational body even if the camshaft is subjected to the reaction of a valve spring, and capable of reducing the impulsive generated in the phase variable device and delivered to the engine. MEANS FOR ACHIEVING THE OBJECTThe objects can be achieved by the inventive phase variable device which includes: a first rotational body, an intermediate rotational bode integral with the camshaft of an engine, a second rotational body, all rotatably arranged on the same camshaft, the device adapted to control phase angle of the second rotational body, thereby varying the phase angle of the intermediate rotational body. The second rotational body is placed in substantial contact with the inside of the hollow cylindrical section of the intermediate rotational body. A circular eccentric cam, integral with the second rotational body and adapted to rotate about an eccentric center thereof, causes a cam guide plate to reciprocate in the direction perpendicular to the rotational axis, which in turn causes slide members protruding from the cam guide plate to move in the radial guides formed in one of the first rotational body and the intermediate rotational body, as well as in skewed guides which are formed in the other one and skewed with respect to a circumference coaxial with the skewed guides.

Abstract: A valve timing controller includes a driving circuit, a control circuit, and a signal line. Receiving electric power from a power source, the drive circuit drives an electric motor according to the control signal, and outputs the rotative direction signal showing the rotation direction of the electric motor. A controlling circuit outputs the control signal generated according to the rotation-direction signal. A signal line transmits the rotation-direction signal to the controlling circuit from the drive circuit. The drive circuit outputs a high-level signal showing the normal rotation direction, and a low level signal showing the reverse rotation direction of the electric motor. When a power supply voltage falls below to the acceptable value, the drive circuit maintains the voltage level of the signal line at high level.
