ABSTRACT:
A thermal engine utilizing a positive displacement rotary expander and preferably a positive displacement rotary compressor in conjunction with an external substantially steady-state thermal source, such as a continuous fuel combustor, the external source heating a high pressure gas that is directed from the thermal source to the rotary expander wherein the gases expand driving a rotor in the positive displacement rotary engine before discharge. An additional embodiment of the thermal engine includes a modified epitrochoidal chamber configuration for the compression cycle and the expansion cycle to utilize the total internal volume for each compression pulse and expansion pulse for obtaining improved thermal efficiency in a manner similar to super long stroke reciprocal piston engines.
