ABSTRACT:
A valve operating mechanism of an internal combustion engine including a first cam rotatable about an axis in timed relation to the engine speed, a second cam rockable about an axis and operatively engaged with a valve of the engine, a rocker arm rockable about an axis and interposed between said first and second cams to provide operative connection therebetween, and means responsive to varations of engine condition for shifting the axis of rocking movement of said rocker arm relative to said axes of said first and second cams thereby varying the angular position of said second cam independently of that of said first cam whereby valve lift, valve timing and the period during which the valve is open are varied in accordance with the varying operating conditions of the engine.
