A thermodynamic machine including an enclosure containing a working gas and having heat exchange surfaces therein, displacement structure moveable within the enclosure in order to displace the working gas in the enclosure and consecutively place the working gas in contact and out of contact with each of the heat exchange surfaces in order to perform consecutive stages of a thermodynamic cycle; and a mechanical power unit subject to pressure of the working gas, the displacement structure causes consecutive passage of a chamber in front of the different heat exchange surfaces, the chamber containing a quantity of working gas that is essentially constant, at least the majority of which is generally stationary in relation to the displacement structure.
