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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
