A gear pump mechanism shown in a variety of applications to control rotational output. Control of the output from the gear pump and feed to the gear pump of hydraulic fluid or oil can be controlled to establish conditions from free wheeling to fully locked. The gear pump includes a sun gear and planetary gears. The sun gear is attached to an output shaft while the planetary gears are rotatably mounted to the pump housing. Through rotation of the housing and control of the flow through the gear pump, relative rotation of the output shaft can be determined. Applications of rotational output control systems using the gear pump mechanism provide adjustable torque limiters, variable rate clutches, differentials, brakes, CVT transmissions, four wheel drive systems and forward and reverse variable rate clutches with no gear backlash.
