Filed:

Dec 22, 2003

Appl. No.:

10/744229

Inventors:

Jedd N. Martin - Providence RI, US
Stephen M. Chomyszak - Attleboro MA, US

Assignee:

Mechanology, LLC - Attleboro MA

International Classification:

F02B053/04

US Classification:

123221, 418207, 418195

Abstract:

The invention provides a toroidal intersecting vane machine incorporating intersecting rotors to form primary and secondary chambers whose porting configurations minimize friction and maximize efficiency. Specifically, it is an object of the invention to provide a toroidal intersecting vane machine that greatly reduces the frictional losses through intersecting surfaces without the need for external gearing by modifying the width of one or both tracks at the point of intermeshing. The inventions described herein relate to these improvements.

Abstract:

The invention provides a toroidal intersecting vane machine incorporating intersecting rotors to form primary and secondary chambers whose porting configurations minimize friction and maximize efficiency. Specifically, it is an object of the invention to provide a toroidal intersecting vane machine that greatly reduces the frictional losses through meshing surfaces without the need for external gearing by modifying the function of one or the other of the rotors from that of “fluid moving” to that of “valving” thereby reducing the pressure loads and associated inefficiencies at the interface of the meshing surfaces. The inventions described herein relate to these improvements.

Filed:

May 21, 2010

Appl. No.:

12/785093

Inventors:

Eric D. Ingersoll - Cambridge MA, US
Justin A. Aborn - Hingham MA, US
Stephen M. Chomyszak - Attleboro MA, US

Assignee:

General Compression, Inc. - Newton MA

International Classification:

F16D 31/02

US Classification:

60408

Abstract:

Systems and methods for operating a hydraulically actuated device/system are described herein. For example, systems and methods for the compression and/or expansion of gas can include at least one pressure vessel defining an interior region for retaining at least one of a volume of liquid or a volume of gas and an actuator coupled to and in fluid communication with the pressure vessel. The actuator can have a first mode of operation in which a volume of liquid disposed within the pressure vessel is moved to compress and move gas out of the pressure vessel. The actuator can have a second mode of operation in which a volume of liquid disposed within the pressure vessel is moved by an expanding gas entering the pressure vessel. The system can further include a heat transfer device configured to transfer heat to or from the at least one of a volume of liquid or a volume of gas retained by the pressure vessel.

Appl. No.:

11/472502

Inventors:

John Hoffman - Washington DC, US
Eric Ingersoll - Cambridge MA, US
Stephen Chomyszak - Attleboro MA, US

International Classification:

F03G 7/00

US Classification:

060641200

Abstract:

The invention relates to systems for stored compressed air without use of combustion. The systems can be installed on the customer side of the meter and creates electricity during peak hours after it has been stored in off peak hours. The invention creates a financial incentive for conserving energy costs by building compressed air storage systems which heretofore have seen little application.

International Classification:

F01C 9/00

US Classification:

418 35, 418 36, 418259, 417481, 91339

Abstract:

The present invention is directed to a peripherally pivoted oscillating vane machine (OVM). The OVM has been optimized for performance and efficiency. This has been accomplished by reducing loads on the drive mechanism and by employing de-phased motion of the peripherally pivoted vanes in conjunction with improved porting configurations as well as valve actuation and manufacture.
