Abstract: A fluid displacement apparatus includes a stator section with a rotor therein. The stator section includes a cylindrical casing, a helically-convoluted chamber section within the cylindrical casing, and a rigid sleeve within the cylindrical casing and separate from the helically-convoluted chamber section. The rigid sleeve includes a circular internal bore. The rotor is rotatably disposed within the cylindrical casing. The rotor includes a helically-lobed section disposed within the helically-convoluted chamber section, and a circular cylinder section disposed within the rigid sleeve. The circular cylinder section provides a fluid passageway between the rigid sleeve and the circular cylinder section. Side loads from the rotor are distributed along a contact line at any point of rotation of the circular cylinder section within the rigid sleeve.

Abstract: A pump fluid driving apparatus includes a housing having a chamber, with two gears mounted within the chamber. The housing includes a first rounded wall section and a second rounded wall section, the first and second rounded wall sections defining at least a portion of the chamber. The gears have teeth located about their respective peripheries and operatively positioned with the teeth of the first gear and the teeth of the second gear intermeshed. The teeth include slotted teeth and solid teeth arranged with uniform spacing in a repeating pattern about the periphery of each of the gears, with each of the slotted teeth having a vane slot and a radially extending vane extending from the vane slot, and each radially extending vane being movable within the respective vane slot and being configured to contact the respective first or second rounded wall sections.

Abstract: An external gear pump including seals, bearings, bushing/seal housings, choke collars and shafts that are all removable for maintenance and/or replacement without removing either endplate or internals from the case assembly. The preferred pump includes four bearing caps that can be removed without removing the pump from its mounted position. By removing the four bearing caps, access is gained inside the pump housing to all of the seals, bearings, bushing/seal housings, choke collars and most importantly, the drive and idler shafts within the pump housing. Further, the two shafts can be slipped out of the pump without disturbing the internal parts and endplates. This capability facilitates maintenance and replacement of major components without removing the pump from its mounted position.

Abstract: A stator for a helical gear device is formed from multiple rigid disks and support rings bonded to the disks. Each disk forms part of a profile having equally spaced or opened lobes which interact with the convex portions of rotor lobes. The disks are bonded to one another to form a disk stack defining a helically convoluted elongated chamber therein. The support rings are fixed concentrically against respective end disks of the disk stack. The rings have an inside diameter substantially equal to the major diameter of the central aperture defined by the radially extending lobes of the disks. As a rotor rotates and nutates inside the stator, it is supported at both ends of the disk stack by the support rings touching tips of the rotor lobes. Thus the full force of the rotor's operational inertia is not borne by the disks alone, thereby increasing their life.

Abstract: A fluid metering device that preferably includes a substantially linear series of intermeshing gears. The fluid metering device includes an inlet port adjacent the intermeshing portion of each pair of gears within the series adjacent the point at which the pair of gears diverge. The device further includes an discharge port adjacent the intermeshing portion of each pair of gears within the series adjacent the point at which the pair of gears converge. The device is configured to convey liquid from a main inlet stream of liquid, through the inlet ports, and out the discharge ports at substantially equal rates. The device preferably includes a pressure balance inlet port and a pressure balance discharge port adjacent the exterior portion of each end gear within the series of gears for balancing forces exerted on the end gear by liquid passing through the various inlet and discharge ports.

Abstract: A stator segment is provided for a helical gear device. The stator segment includes a stator tube and modular stator inserts. The stator tube has an inner profile with at least two internal sides that extend longitudinally along an interior of the stator tube. The modular stator inserts each have an outer profile that substantially matches and fits within the inner profile of the stator tube. The modular stator inserts also each have an interior helical profile that defines a central opening. The modular stator inserts are configured to be removably inserted longitudinally into the stator tube along the inner profile of the stator tube. The inner profile aligns the modular stator inserts to form a continuous helical chamber and prevents rotation of the modular stator inserts relative to the stator tube.
