The invention relates to a method for converting heat energy into mechanical energy by modifying the volume, pressure and temperature of a working medium, wherein the working medium in the first stage (1) is suctioned and the volume of said first stage (1) is increased, whereupon it is converted into a second stage (2) when the volume of the first stage (1) is reduced and the volume of the second stage is increased, whereupon the working medium is converted into a fourth stage (4) via a third stage (3) wherein the volume of the second stage (2) is reduced, heat is also supplied and the volume of the fourth stage (4) is increased, whereupon the working medium is converted into a fifth stage (5) from the fourth stage (4) wherein the volume thereof is reduced and in the fifth stage (5) the volume of said fifth stage is expanded. The inventive method discloses a thermodynamic cycle process comprising five cycles. The invention also relates to a device for carrying out said method.

L'invention concerne un procédé pour transformer de l'énergie thermique en énergie mécanique par modification de volume, de pression et de température d'un fluide de travail. Selon ce procédé, le fluide de travail est aspiré dans un premier étage (1), ce qui provoque une augmentation de volume de ce dernier, puis il est transféré dans un deuxième étage (2), ce qui provoque une diminution de volume du premier étage et une augmentation de volume du deuxième étage. Il est ensuite transféré, avec apport de chaleur simultané, dans un quatrième étage (4) en passant par un troisième étage (3), ce qui provoque une diminution de volume du deuxième étage et une augmentation de volume du quatrième étage, avant d'être transféré dans un cinquième étage (5), ce qui provoque une diminution de volume du quatrième étage, ledit fluide de travail étant dilaté dans le cinquième étage (5) qui subit une augmentation de volume. Le procédé selon l'invention constitue ainsi un cycle fermé thermodynamique à cinq temps. L'invention concerne également un dispositif pour la mise en oeuvre dudit procédé.
