Abstract

La présente invention concerne un dispositif de réglage de puissance pour un compresseur à piston rotatif. Suivant l'invention, le compresseur à piston rotatif comprend un carter formé d'une enveloppe 1 et de deux parties latérales 3. Le carter est traversé par un arbre excentrique 4 portant un piston rotatif 6. Dans au moins une partie latérale 3 dans le sens de rotation dudit piston, en aval du canal d'admission 11, on a prévu au moins un évidement 14 obturé par un bouchon 15 qui, en cas de position reculée du bouchon 15, met en communication lors du balayage par les joints d'étanchéité 9 ou les bords du piston 6, une chambre de travail A se trouvant en temps de compression avec ledit canal d'admission 11 par l'intermédiaire d'une cavité prévue à l'intérieur dudit piston L'invention permet un réglage sans échelon de la puissance des compresseurs.
