Abstract:
The present disclosure describes an Oscillating Vane Machine (OVM) wherein one or more of the chamber sealing counter-faces are removable The OVM includes a stator, at least one chamber disposed within the stator, the chamber characterized by at least one counter-face, and at least one port, a vane disposed within the chamber, the vane characterized by a vane shaft and a vane tip, said vane tip being disposed proximally to the counter-face, ofthe chamber, and a removable liner, disposed between the vane tip and the counterface
Abstract:
The present disclosure relates to multi-staging within an Oscillating Vane Machine (OVM), in particular, to multi-staging within a single OVM and controlling inter-stage pressure ratios therein.
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 relates to the uses and combinations of elastomeric seals, elimination of joints between segments of a seal grid, introduction of labyrinth seal profiles, abradable or conformable vane coatings, and crushable vanes or vane edges to provide lower leakage, lower friction, lower operating temperatures, and higher efficiency within an Oscillating Vane Machine.
Abstract:
The present invention relates to improved integrated valve assemblies, preferably, for use in an oscillating vane machine (OVM) that provide easy assembly and maintenance, direct fluid communication between the working chamber and suction and discharge manifold, and the avoidance of the use of fasteners in contact with or adjacent to the working chamber.
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.
Abstract:
The invention provides a toroidal intersecting vane machine incorporating intersecting rotors to form primary and secondary chambers (208, 202) 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 (302, 304) at the point of intermeshing. The inventions described herein relate to these improvements.
