    摘要： 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.

    摘要： A pressure balancing system for a pump. In one example, the pressure balancing system has: a housing; a first rotor a first shaft, a first face surface; a second rotor, 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 thus biasing the first rotor toward the second rotor.

    摘要： 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.
