Abstract

Moteurs à combustion interne avec une chambre de travail cylindrique (1) dans laquelle coulisse un piston (3), et fermée par une culasse (4) avec un dispositif d'injection (5) de combustible liquide pulvérisé sous haute pression et fonctionnant selon le cycle à deux temps, avec un système de balayage en boucle à travers la culasse, avec deux soupapes de révolution et d'axes confondus, l'une, d'admission (7), externe coopérant avec un siège (15) de la culasse, l'autre, d'échappement (6), présentant une forme tubulaire avec une portée s'appliquant contre un siège (16) formé à la partie inférieure de la soupape d'admission (7), la soupape d'admission s'ouvrant vers la chambre de travail et la soupape d'échappement s'ouvrant en direction opposée, pour délimiter, entre elles, un passage d'échappement (8), le dispositif d'injection (5) débouchant dans la chambre de travail sensiblement au centre d'un moyeu central (21) porté par la culasse et autour duquel coulisse la-soupape d'échappement (6).
