Abstract
Ambient temperature thermal energy cryogenic engine with constant pressure with continuous “cold” combustion at constant pressure and with an active chamber operating with a cryogenic fluid stored in its liquid phase, and used as a work gas in its gaseous phase and operating in a closed cycle with return to its liquid phase. The initially liquid cryogenic fluid is vaporized in the gaseous phase at very low temperatures and supplies the inlet of a gas compression device, which then discharges this compressed work gas, still at low temperature, and through a heat exchanger with the ambient temperature, into a work tank or external expansion chamber fitted or not fitted with a heating device, where its temperature and its volume will considerably increase in order to then be preferably let into a relief device providing work and for example comprising an active chamber according to international patent application WO 2005/049968.
