ABSTRACT:
A valve operating mechanism for controlling inlet and exhaust valves of an internal combustion engine. A camshaft comprising a cam which imparts valve lift for high speeds of the engine, and a lobe portion which imparts no lift for valve deactivation during low speeds of the engine. A first finger follower follows the lobe portion, and a second finger follower follows the cam wherein the first follower is rockable about a fixed fulcrum and the second follower is rockable about a movable fulcrum.
