Abstract

La présente invention concerne un système de compresseur d'air qui comprend au moins un étage de piston raccordé à une admission d'air du compresseur par une soupape d'admission et raccordé à une sortie d'air comprimé du compresseur par une soupape d'évacuation, un moteur entraînant l'étage de piston et un régulateur réglable raccordé entre l'admission d'air et la soupape d'admission. Une unité de commande commande le moteur et le régulateur pour fermer sensiblement ce dernier afin de décharger l'étage de piston en cas de besoin.
