Abstract

Cette invention concerne un dispositif comprenant un corps (1) dans lequel se trouve une chambre (2) à haute pression renfermant un pignon hélicoïdal d'entraînement et un pignon hélicoïdal mené (3, 4) engrenants. Ces pignons hélicoïdaux (3, 4) sont fixés sur des arbres (5, 6), lesquels sont eux-mêmes montés sur des supports (7, 8) et sont reliés par des pignons de synchronisation (9). La chambre (2) se trouve en communication avec des buses d'entrée et de sortie (10, 12). Dans le corps (1) se trouvent également des chambres (18, 19) réservées à la circulation d'huile et séparées de la chambre (2) par l'intermédiaire d'éléments d'étanchéité. Ce dispositif comporte un système permettant de soulager les pignons hélicoïdaux (3, 4) des efforts radiaux et axiaux qui s'exercent sur eux. Lors de la transformation d'énergie thermique en énergie mécanique, des rapports spécifiques sont maintenus entre la masse m1 du condensat et la masse m2 du fluide caloporteur, et les quantités de fluide caloporteur lors de la libération de l'énergie thermique transformée en énergie mécanique. Ces rapports sont déterminés en choisissant les dimensions géométriques de la chambre à haute pression (2) et celles des pignons hélicoïdaux.
