Abstract: A positive displacement device that converts energy, namely positive displacement compressors that rotate in a single rotational direction to displace working fluid contained in operating chambers. The device described herein is particularity advantageous for the ability to achieve high compression ratios in combination with high discharge pressure and high volumetric throughput in a single stage.

Abstract: 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.
