Abstract

Le moteur à piston rotatif comprend un cylindre (11), un piston (3) et un arbre de sortie (2), une lumière d'admission (14), une lumière d'injection (15) et une lumière d'échappement (16) dans la paroi du cylindre. Ledit cylindre est un bloc-cylindre fermé, de la forme d'une bouée de sauvetage. Sur la paroi interne du cylindre est ménagée la lumière du segment fermé (12) en forme de bande. Un mécanisme de cloisonnement (131, 13) est installé à l'intérieur du cylindre. L'arbre de sortie (3) se trouve au centre du cylindre. Le corps principal du piston est placé dans le cylindre (11), et la bielle (31) du piston s'étend depuis la lumière du segment fermé jusqu'au centre du cylindre. Cette bielle est reliée à l'arbre de sortie. La lumière du segment fermé est munie d'une rondelle d'étanchéité (121) se déplaçant en même temps que le piston. Les lumières d'admission (14) et d'injection (15) d'une part, et la lumière d'échappement (16) d'autre part sont disposées sur la paroi du cylindre de chaque côté du mécanisme de cloisonnement.
