Abstract
A valve system for an internal combustion engine capable of changing the valve timing and valve lift of the intake and exhaust valves driven by rocker arms and overhead camshafts. A cam support member is pivotally mounted to the engine head and is positioned by a gear segment mounted to the camshaft support member in combination with a drive including a worm gear and a servomotor located on an engine block. The camshafts are driven by the crankshaft coupled with an idler gear. The idler gear is coupled with the camshaft gears through reduction gears, reducing the overall size of the drive and allowing flexibility as to valve timing.
