Abstract

L'invention concerne un dispositif permettant de produire de l'énergie électrique à partir d'une chaleur basse température. Ce dispositif comprend deux cylindres de travail (Z1, Z2) sensiblement verticaux et partiellement remplis d'un fluide; un contenant à gaz (WT1) destiné à être maintenu à une haute température; un contenant à gaz (WT2) destiné à être maintenu à une basse température; un conduit de raccordement entre les cylindres de travail (Z1, Z2) pour le trop-plein de fluide entre les cylindres de travail (Z1, Z2); un piston (K1) placé dans le conduit de raccordement permettant de produire un travail mécanique à partir du mouvement du fluide, le piston (K1) coopérant de préférence avec un générateur linéaire (L1) afin de produire de l'énergie électrique à partir du déplacement. Le rendement particulièrement avantageux de ce dispositif est dû aux soupapes de commande qui permettent de raccorder au choix le contenant de gaz (WT1, WT2) aux cylindres de travail (Z1, Z2) ainsi qu'à un dispositif de pompage qui permet de modifier la quantité de fluide dans les cylindres de travail (Z1, Z2).
