Abstract

Procédé pour la régulation des compresseurs à vis du type monovis permettant de faire varier le débit d'un compresseur sans avoir à étrangler l'aspiration ou à déplacer des portions du carter. Dispositifs pour réaliser le procédé. Le procédé consiste à écarter au moins un pignon de sa position de travail et à créer un jeu par lequel le gaz s'échappe sans être comprimé. Le procédé permet de réduire considérablement les pertes passives à débit partiel et autorise plusieurs régimes partiels différents lorsqu'il est appliqué à des machines utilisant deux pignons coopérant avec la même vis.
