Abstract: A fluid metering device (30) preferably includes a substantially linear series of intermeshing gears (310, 314). The device includes an inlet port (340I-342I) adjacent the intermeshing portion of each pair of gears (310-313) within the series adjacent the point at which the pair of gears diverge. The device (300) further includes a discharge port (340D-342D) adjacent the intermeshing portion of each pair of gears within the series adjacent the point at which the pair of gears converge. The device (30) is configured to convey liquid from a main inlet stream of liquid, through the inlet ports (340I-342I), and out the discharge ports (140D-142D) at substantially equal rates. The device (30) preferably includes a pressure balance inlet port (344I-345I) and a pressure balance discharge port (344D-345D) adjacent the exterior portion of each end gear (310, 314) within the series of gears (310-314) for balancing forces exerted on the end gear (310, 314) by liquid passing through the various inlet and discharge ports (340I-342I, 340D-34dD).

Abstract: Toothed gears and lobed gears intermesh to create large volume pockets in gear sets of a given size. The pockets are larger than the pockets that exist in current tooth or lobe pumps and provide the benefit of a pump that better handles shear sensitive liquids. The toothed gears and lobe gears are preferably involute-shaped and improve upon standard spur and helical gear designs by omitting alternate teeth on the standard toothed gears and filling in corresponding gaps on the mating standard lobed gears. Additional tooth and lobed gear rotors may be added in tandem as additional pairs of gears to the shafts and circumferentially offset to provide driving tooth engagement between at least one pair of the toothed and lobed rotors at every point around the rotational circumference of the rotors. This spur gear or helical gear configuration eliminates the need for separate driving/synchronizing gears.
