Abstract

La présente invention concerne un moteur à combustion externe. Le moteur à combustion externe comprend un fluide de travail et un élément de brûleur destiné à chauffer le fluide de travail du moteur, au moins une culasse délimitant un espace de travail contenant le fluide de travail, au moins un cylindre de piston contenant un piston destiné à compresser le fluide de travail, un refroidisseur destiné à refroidir le fluide de travail, un carter comprenant un vilebrequin destiné à produire une sortie moteur, un entraînement pendulaire tournant autour d'un balancier à culbuteur afin d'entraîner le vilebrequin, une tige de piston reliée au piston, un entraînement pendulaire entraîné par la tige de piston et une tige de liaison reliée à une première extrémité au mécanisme pendulaire et à une seconde extrémité au vilebrequin afin de convertir le mouvement rotatif du mécanisme pendulaire en mouvement rotatif du vilebrequin. Le moteur à combustion externe comprend également une unité d'étanchéité de tige de piston comprenant un carter, un joint à labyrinthe de cylindre et au moins un ensemble de joint flottant de tige monté dans le joint à labyrinthe, l'ensemble de joint flottant de tige comprenant au moins un joint de tige monté sur l'ensemble de joint flottant de tige.
