ABSTRACT:
A system for converting the output of a constant speed motor to variable fluidic flow at the ends of a linear actuator comprising a drive gear coupled with an electric motor for concurrent rotation at a fixed rotational speed; a driven gear operatively coupled to the drive gear; a drive train operable in response to rotation of the drive gear to rotate the driven gear, the gear train including adjustment mechanisms for selectively varying the rotational orientation between the drive and driven gears; a pump having a pair of spaced cylinders in axial alignment with pistons coupled through a reciprocal connecting shaft and with a connector rod pinned at its midpoint to the connecting shaft for oscillation; rigid links coupling the ends of the connector rod with the drive and driven gears so that rotation of the drive and driven gears will oscillate the connecting rod and reciprocate the connecting shaft at a speed correlated to the orientation of the adjustment mechanisms of the gear train; and fluidic lines coupling the outputs of the cylinders to the ends of a linear actuator so that adjustment of the gear train will vary the output of the pump to vary the fluidic flow to the linear actuator.
