ABSTRACT:
The invention provides a method and apparatus for operating any centrifugal piston expander to convert energy derived from a heat source into mechanical energy. Pressured gas received from the heat source is circulated through the centrifugal piston expander, then to a series connected heat exchanger and compressor to recompress same and to remove sufficient heat to satisfy the entropy requirements of the closed cycle, and then is resupplied to the heat source for recirculation. Several types of centrifugal piston expanders are disclosed including one type wherein the centrifugally produced stroke of each piston is utilized to force the expanded gas into the subsequent apparatus.
