Patent number: 11614089Abstract: 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.Type: GrantFiled: April 13, 2021Date of Patent: March 28, 2023Inventors: Alejandro Juan, Michael Sereda-Mohr, Erik Farrell

Patent number: 11168683Abstract: 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.Type: GrantFiled: March 12, 2020Date of Patent: November 9, 2021Assignee: Exponential Technologies, Inc.Inventors: Kristjan Gottfried, Erik Farrell, Michael Sereda-Mohr

Publication number: 20200291935Abstract: 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.Type: ApplicationFiled: March 12, 2020Publication date: September 17, 2020Inventors: Kristjan Gottfried, Erik Farrell

Patent number: 9777729Abstract: This disclosure concerns an advanced nutating positive displacement device having a high power to mass ratio and low production cost. This device in one example forms an exemplary pump as will be discussed in detail. The examples disclosed herein are of the rotary positive displacement type, but in a class by themselves. The devices are formed by a nutating rotor having a face comprising lobes and valleys, and a fixed stator also having a face with lobes and valleys. The face of the rotor opposes and cooperates with the face of the stator. The opposing faces define chambers that change volume with rotation of the rotor.Type: GrantFiled: March 15, 2013Date of Patent: October 3, 2017Assignee: Exponential Technologies, Inc.Inventors: Alejandro Juan, Curtis Patterson, Erik Farrell, Stephen F. Scott, Kyle Fiolka

Patent number: 9121275Abstract: 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.Type: GrantFiled: December 19, 2012Date of Patent: September 1, 2015Assignee: Exponential Technologies, Inc.Inventors: Curtis Patterson, Alejandro Juan, Kristjan Gottfried, Erik Farrell
