  • the working material must always be in a liquid state so that heat exchange can occur between the high-temperature waste heat of the working material in one cylinder and the low-temperature heat of the working material in the other cylinder. Therefore, a material having a boiling point higher than that of a high heat source should be selected. In other words, if the temperature of the high heat source is t °C and the boiling point of the working material is b °C, the inequality of t ⁇ b must be satisfied.

Abstract

La présente invention concerne un moteur thermique hautement efficace sans chaleur perdue qui comporte deux cylindres identiques (Y et Y') formant une paire bilatéralement symétrique telle que représentée sur la figure 1 et permet d'échanger la chaleur perdue à haute température dans le cylindre d'un côté et la chaleur à basse température dans le cylindre de l'autre côté au moyen d'un échangeur de chaleur (E) disposé entre la paire de cylindres et réutilise ainsi la chaleur perdue sans la dissiper.
