Abstract

A fluid pumping system for an engine includes a pump; a summing differential connected to the pump; a gearbox connected to the summing differential, wherein the gearbox causes the pump to rotate to provide a fluid flow in the engine via the summing differential; and a motor connected to the summing differential, wherein the motor adjusts a rotational speed of the pump via the summing differential
