Abstract
A heat engine with external hot source in which the engine has at least one variable volume working chamber for a working gas, and a distribution mechanism that connects this chamber to a cold input from an energy receiving path during an outgoing transfer phase and to a hot output of the energy receiving path during an incoming transfer phase, the energy receiving path being intended to heat the working gas outside the chamber on contact with the external hot source, wherein the distribution mechanism is timed in such a way as to: maintain pressure in the energy receiving path; during stable operation, connect the working chamber with the cold input from the energy receiving path whilst the pressure in the chamber is lower than the pressure in the energy receiving path.
