Abstract

L'invention concerne un silencieux à diaphragme pour le fonctionnement silencieux d'un compresseur recevant un flux à pression supérieure à la pression atmosphérique et un flux à pression inférieure à la pression atmosphérique. Le silencieux à diaphragme comprend une chambre à pression recevant le flux à pression supérieure à la pression atmosphérique, une chambre à vide recevant le flux à pression inférieure à la pression atmosphérique, et un diaphragme souple divisant la chambre à pression recevant le flux à pression supérieure à la pression atmosphérique et la chambre à vide recevant le flux à pression inférieure à la pression atmosphérique, de sorte que le flux à pression supérieure à la pression atmosphérique et le flux à pression inférieure à la pression atmosphérique s'annulent l'un l'autre grâce au diaphragme souple.
