Abstract

La présente invention concerne une soupape d'échappement pour un compresseur à piston rotatif. Ce compresseur comprend un carter avec une enveloppe 1 à surface interne 2 à un seul lobe et contient un piston 6 monté rotatif sur l'excentrique 4 d'un arbre excentrique 5. Le piston délimite deux chambres de travail à volume variable A et B. Pour le processus de compression, on a prévu un canal d'échappement 9 contenant une soupape d'échappement 10. L'orifice d'échappement est formé d'une pluralité d'orifices 11 rassemblés en deux groupes dans le sens de rotation D du piston. Dans le canal 9 à proximité de la surface interne d'enveloppe 2, on a disposé deux surfaces d'appui 12 pour les deux soupapes d'échappement 10 au niveau desquelles débouchent les orifices 11. L'invention permet d'obtenir une plus grande section d'écoulement pour les gaz.
