Abstract

L'invention concerne les compresseurs. Le compresseur rotatif étanche à huile décrit comporte une soupape de décharge réduisant ou fermant l'admission du compresseur lorsque la pression de ce dernier s'élève au-dessus de la pression de fonctionnement normale (lorsque la demande en air comprimé se réduit ou cesse), une soupape de pression minimum assurant que la pression dans le compresseur ne tombe jamais en dessous d'une valeur minimum préterminée, des moyens de tirage ventilant les espaces de compression et de refoulement lorsque la pression dans la conduite d'alimentation en air comprimé est supérieure à une valeur prédéterminée excédant la valeur normale de fonctionnement En conditions << à vide >>, la pression est donc réduite à un niveau relativement bas, ce qui réduit considérablement l'énergie consommée.
