Abstract

Ce dispositif, approprié en particulier pour les compresseurs hélicoidaux à injection d'huile, comprend une soupage de réglage d'aspiration (4) et un clapet anti-retour (5) qui ferme à joint étanche. Les deux appareils (4, 5) sont disposés en série, dans un corps (1) intercalé dans la conduite d'aspiration. Pour obtenir une faible perte de charge et une construction simple, les deux appareils (4, 5) sont constitués par des appareils à volet oscillant, le volet (12) du clapet anti-retour (5) fermant à joint étanche un siège de clapet (6) et pouvant osciller à l'encontre d'une force de rappel (15) autour d'un axe (14) situé en dehors des limites de la section de passage du siège de clapet (6).
