Abstract

ABRÉGÉ : Il est décrit un moteur à combustion externe qui comprend un élément brûleur, une tête d'élément chauffant, un cylindre-piston contenant un piston, un refroidisseur et un vilebrequin. Le vilebrequin comprend un vilebrequin, une bielle de piston reliée au piston, un mécanisme d'entraînement pour convertir le mouvement linéaire de la bielle de piston en un mouvement rotatif du vilebrequin et un palier à croisillon linéaire qui est relié rigidement à la tête de piston à une extrémité et au mécanisme d'entraînement à l'autre extrémité. Le moteur à combustion externe comprend également un joint d'étanchéité à jeu de piston et une unité de joint d'étanchéité de bielle de piston qui possède des joints d'étanchéité de bielle flottants. Le piston comprend un dôme interne pour réduire un transfert de chaleur axial par rayonnement et convection. Date reçue / Date Received 2020-08-31
