Abstract
L'invention concerne un appareillage cryogénique permettant d'atteindre de très basses températures (inférieures à 100 degrés K). La machine frigorifique qui fonctionne en circuit fermé et qui est capable de produire des températures très basses (inférieures à 100 degrés K) effectue un cycle combiné avec expansion du gaz et production de travail de la part du gaz contre un piston, et au moyen d'un système de compression à aspiration. Le gaz en expansion peut être utilisé pour agir sur le moteur de manière que le travail effectué par le gaz pendant l'expansion accélère ce moteur qui agit en tant que frein en accumulant l'énergie en vue de la phase suivante de redescente du piston. Application aux appareils frigorifiques.
