Abstract
A positive displacement expander with an operating fluid chamber of expansive volume regulated by a shifting head. The shifting head may enhance rotation of a housing utilized to rotate a shaft for providing work to any of a variety of power retrieval devices. Additional efficiencies may also be realized through unique hydraulic layouts for circulating of the operating fluid from a heat exchanger, through the rotary device and to a cold exchanger for continuous operating of the rotary device.
Claims20
A rotary positive displacement device comprising:
- a rotatable offset housing defining an operating fluid chamber;
- a casing about the housing for altering a volume of the chamber;
- and
- a position shiftable head further defining the chamber responsively regulate chamber volume in response to the altering thereof.
A system comprising:
- a rotary positive displacement device with a volume expanding operating fluid chamber defined in part by a shifting head responsive to pressure in the chamber;
- a dedicated heat exchanger for supplying a heated operating fluid to the device chamber;
- and
- a dedicated cold exchanger for obtaining the operating fluid from the device upon rotation of a housing accommodating the shifting head.
A method of obtaining power from a system, the method comprising:
- circulating operating fluid to a rotary positive displacement device for rotation thereof;
- circulating a working fluid from the rotary device to a power retrieval device for the obtaining of the power in response to the rotation;
- and
- shifting a position of a head in fluid communication with the rotary device to enhance the rotation.
