The present invention describes an external combustion rotary engine, which, due to the separate combustion chamber of the engine, is possible the operation at a lower temperature than those internal combustions, therefore, the engine efficiency is greater. Another characteristic presented by the external combustion rotary engine is that it has concentric expansion chambers and through cams that have a rotor, it is possible to take advantage of the expansion force of the working fluid. The external combustion rotary engine is of closed-cycle operation, so the consumption of additional water is reduced as work fluid since the amount of water within the system is sufficient. Finally, it is worth mentioning that the external combustion rotary engine, thanks to its operation principle, can be applied in the electric power generation field.

This invention relates to the field of internal combustion engines and compressors in general and to linear compressors, in particular these used as in U.S. Pat. No. 8,056,527, by accurately controlling the pressure being delivered into the combustion chambers of said engine while returning unused energy of the compression phase into the motor for complete expansion. Another improvement relates to a pressure compensated vane to be used inside grooves of the motor assembly rotor. This invention enables the vane to seal against the cavity of the housing tightly with minimal force.
