    Abstract: Several examples of a pressure balancing system for a pump. In one example, the pressure balancing system comprises: a housing; a first rotor within the housing having a first axis of rotation, a first shaft, a first face surface; a second rotor having an axis of rotation, a second face surface adjacent the first face surface of the first rotor; the face of the first rotor, the face of the second rotor, and an inner surface of the housing forming at least one working fluid chamber; an annular ring fitted around a shaft, adjacent a first pressure chamber having a fluid connection through the housing; the annular ring configured to bias the first rotor toward the second rotor when fluid is supplied under pressure to the first pressure chamber; a fluid conduit is configured to convey fluid to a pressure chamber between the housing and the annular ring to bias the annular ring against a radial extension of the first shaft thus biasing the first rotor toward the second rotor.

    Abstract: Provided herein are multiple variations, applications, and variations for producing electrical power from a flowing fluid such as a gas or liquid under pressure, for example natural gas flowing through a pipeline, by means of one or more positive displacement devices that drive one or more electrical generators. The electrical generators may be immersed in the flow stream together with the positive displacement devices as disclosed, or alternately may be isolated from the flow stream, such as by magnetic coupling, in order to promote longevity and to decrease the risk of accidental discharge or explosion of the fluid in the flow stream. To further decrease such risks, the positive displacement devices may isolate the drive fluid from the environment without the use of dynamic seals.

    Abstract: Disclosed herein are several embodiments of rotors (gears) which utilize spherical involute curves to determine the surfaces of the lobes (teeth). In some embodiments the contact surfaces are radial projections of spherical involute surfaces. In other embodiments the contact surfaces have a root and/or tip of a spherical involute curve, but are barreled or otherwise curved to reduce the point stress on each rotor. The rotors may also be configured where torque transfer is provided at a first set of lobes (teeth) and backlash removal is provided on teeth radially opposed to the first set of lobes (teeth). As the apparatus rotates, the position of torque transfer remains substantially the same, as does backlash prevention/removal, but the teeth providing these operations vary. The rotors may also be used for fluid flow.

    Abstract: Disclosed herein is a valveless multitube pulse detonation engine including: a plurality of detonation tubes, wherein each detonation tube comprises an independent discharge outlet, and the plurality of detonation tubes interconnected at a common air/fuel mixture intake port. In the disclosed engine, an air and fuel mixture is detonated in the detonation tubes simultaneously, and the common air/fuel mixture intake port minimizes back-pressure caused by detonating the air/fuel mixture by directing multiple reverse shock waves into one another and effectively using the back-pressures as reacting surfaces for one another and effectively reducing the effect of back flowing shock waves moving towards upstream. The detonation tubes may be non-linear, and may have independent discharges. The independent discharges may be coupled to an adapter nozzle terminating in a combined exhaust outlet.
