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.
