Abstract

Procédé pour la régulation du débit des compresseurs à vis engrénant avec un pignon. Le pignon 4, calé par un circlips 6 contre un support 5, est porté par un arbre 7 et engrène avec une vis 1. Un piston 16 muni d'une tige de commande 17 permet de mouvoir l'arbre 7 axialement pour soulever le pignon 4 par rapport à la vis 1. Application à la régulation de débit des compresseurs à vis et pignon.
