Abstract

La présente invention concerne un moteur à pistons rotatifs qui comprend un corps de cylindre (1), une culasse de cylindre (15), deux jeux de pistons (3A, 4B) et des embrayages (10, 42), deux jeux de pistons (3A, 4B) étant respectivement agencés sur le diamètre extérieur d'une base et d'un moyeu de piston (63). L'embrayage comprend une roue libre unidirectionnelle montée sur le diamètre intérieur du moyeu de piston et une roue libre unidirectionnelle commandée montée dans le diamètre intérieur d'un arbre creux (32) sur la face extérieure du moyeu de piston. Lorsqu'un ensemble quelconque des pistons tourne, l'admission, la compression, le fonctionnement et l'échappement sont réalisés en même temps. La position d'un jeu de pistons lorsque sa course de compression est terminée est derrière l'autre jeu de pistons à ses courses de combustion et d'explosion pour que la force d'inertie rotative du piston puisse être relâchée. Le moteur à pistons rotatifs possède une structure simple et compacte et une propriété d'étanchéité satisfaisante est possible.
