Abstract

Moteur à impulsions piston à gaz comprenant un tube de pulvérisation (1) dans lequel est agencée au moins une chambre de combustion (2). A l'intérieur du tube de pulvérisation (1) et/ou sur le côté latéral dudit tube (1) se trouve au moins un injecteur de fluide haute pression (3) qui opère globalement dans la même direction que le tube de pulvérisation (1) et/ou au moins un injecteur de fluide de pulvérisation haute pression (3) qui opère globalement à direction opposée à la direction globale de pulvérisation. L'injecteur de fluide haute pression(3) est en communication fluidique avec une source de fluide haute pression (4) via une soupape de commande de pulvérisation de fluide (5). Le moteur compte moins de pièces mobiles et possède un taux de compression élevé, ce qui permet d'éviter les difficultés de lubrification dans les conditions moteur de lubrification existantes, ainsi que les problèmes dus au fait qu'un statoréacteur pur ne peut pas être lancé à partir d'un état de repos et ne peut pas travailler à basse vitesse.
