ABSTRACT:
A highly efficient apparatus for actuating a valve. An input mechanism drives the apparatus through an input member. Torque is increased as a plurality of driver discs eccentrically rotate about a central shaft member and engage an output member via low-friction, roller means. The output member engages a valve stem which opens or closes the valve.
