ABSTRACT:
A linear actuator has four drive gears which engage two racks. The actuator movable member may comprise two racks which have gear teeth which face inwardly and towards each other, or a single rack which has gear teeth which faces outwardly. In either case, four gear drives to engage the rack, two gear drives on each side. A plurality of linear actuators may be used to provide for position control in two or more directions. Control is provided by a servo mechanism.
