ABSTRACT:
A thermal machine utilizing a positive displacement element which oscillates at a damped resonant frequency is disclosed. The positive displacement element controls the volume of expander and compressor subchambers. A heat exchanger is provided which includes a high temperature heat source, a low temperature heat source, and at least one heat sink. Valves control the flow of fluid into and out of the expander subchamber so that the subchamber acts to expand the fluid. A first working fluid is conducted through the expander subchamber, one of the heat sinks, a compressing device and the high temperature heat source in series. A second working fluid is conducted through the compressor subchamber, one of the heat sinks, an expanding device and the low temperature heat source in series.
