Abstract

L'invention concerne un moteur à transmission deux temps pour dispositif de puissance, utilisant des pistons intégrés disposés de manière opposée dans une direction horizontale ; la position médiane des pistons (11) étant munie de deux rangées de crémaillères supérieure et inférieure (13) raccordées à un engrenage (15) sur un arbre de transmission de puissance (10) ayant une demi-couronne d'engrenage ; une moitié de la surface périphérique de l'engrenage (15) comportant des dents et l'autre moitié étant lisse ; et les crémaillères supérieure et inférieure (13) venant en prise en alternance avec l'engrenage (15) de l'arbre de transmission de puissance (10) et poussant l'arbre de transmission de puissance (10) pour mettre en œuvre en continu une rotation circulaire dans une direction, évitant ainsi le défaut d'une transmission de couple instable d'un moteur classique utilisant une combinaison de bielle et essieu coudé. Deux extrémités des pistons (11) sont munies d'une sortie d'air (14) raccordée à une soupape d'échappement (12) ; et un gaz résiduaire est évacué par l'intermédiaire d'une sortie d'air (4) de logement par la sortie d'air (14) de piston contournant un joint d'huile (7) de boîtier. La présente invention résout les problèmes de fuite d'huile moteur et d'échappement de gaz non respectueux de l'environnement résultant de l'échappement par un joint d'huile de piston de moteur à deux temps traditionnel du gaz par l'intermédiaire d'une sortie d'air de boîtier et évite les défauts existants dans l'état de la technique de l'échappement et de la consommation d'huile.
