Abstract: A control device controls intake and exhaust valves of an internal combustion engine. The device comprises a first flange provided by a cam shaft of the engine, which flange has a first radially extending elongate slit. A second flange faces the first flange with a certain clearance therebetween and is secured to a drive shaft to rotate therewith. The second flange has a second radially extending elongate slit. An annular member is disposed within the clearance and rotatable about an axis of the drive shaft. First and second pins are rotatably held by opposed sides of the annular member respectively. These pins are positioned at diametrically opposed positions with respect to a center of the annular member and slidably engaged with the first and second elongate slits respectively. A drive mechanism is employed for pivoting the annular member about a pivot axis eccentric to the axis of the drive shaft in accordance with an operating condition of the engine.

Abstract: The invention relates to a drive mechanism for connecting an input shaft to an output shaft and superimposing on the output shaft a variable oscillatory motion determined by the position of a reaction member. The drive mechanism comprises an input disc fast in rotation with the input shaft, and defining a slideway transverse to the axis of the input shaft. A sliding member is made to slide along the slideway by a block journalled within a pivotable yoke, the block being itself slidable in a second slideway defined by the sliding member. A crank pin fixed to the output shaft is connected slidably to the sliding member such that as the sliding member slides along the slideway, the phase of the output shaft is varied with respect of the phase of the input shaft. A second similar mechanism drives a weight with opposite phase in order to cancel out the reaction torque on the input shaft.

Abstract: An internal combustion engine has n member of cylinders, a piston in each cylinder connected to a crankshaft (2), each piston being in phase or out of phase with the others by A.degree. or a multiple thereof (A=720/n), cams for actuating inlet and exhaust valves to each cylinder, and a cam drive mechanism (5) which rotates the cams in phased relationship with the crankshaft (2) to open the valves in sequence for a desired angle of rotation of the crankshaft. The cam drive mechanism also includes means for combining the rotational movement of the cams with a phased oscillatory movement of the camshaft (3) and cams of variable amplitude about the axis of rotation at a frequency f times the crankshaft frequency so that over the period which the valves are opened and/or their timings variable, f has the following values:f=2n when the number of cylinders n=1;f=n or n/2 when n=2;and f=n/2 when n=3 or more. The selection of the frequency of the oscillations allows all the cams to be mounted on the same camshaft.

Abstract: A device, particularly for controlling the opening and closing of valves of an internal combustion engine, comprises a camshaft on which a plurality of cams are mounted for rotation relative to the shaft. Each cam is driven by the shaft through an intermediate member which rotates about an axis eccentric to the shaft axis. A drive member rotatable with the shaft has a pin which engages in a radial slot on one side of the intermediate member, and likewise the cam has a pin engaging in a radial slot on the other side of the intermediate member, these slots being preferably 180* spaced apart.

Abstract: A valve timing adjusting device adjusts an opening/closing timing of a first valve driven by a rotation of a first camshaft and an opening/closing timing of a second valve driven by a rotation of a second camshaft. The valve timing adjusting device includes a first driving circuit controlling a first motor configured to generate a torque to shift a rotation phase of the first camshaft and a second driving circuit controlling a second motor configured to generate a torque to shift a rotation phase of the second camshaft. A first switching element of the first driving circuit operates at a switching frequency that is different from that of a second switching element of the second driving circuit.

Abstract: A control unit for an internal combustion engine is configured for allowing smooth operation of the internal combustion engine by increasing an intake amount while maintaining an opening timing of an intake valve constant, at the time of low-rotation, high-load state. A valve opening/closing timing control apparatus includes a phase adjustment mechanism configured to vary a relative rotational phase between a driving side rotary body rotatable in synchronism with a crankshaft of the internal combustion engine and a driven side rotary body rotatable together with an intake cam shaft. After an opening timing of the intake valve, the relative rotational phase is displaced in the advancing direction.
