Abstract

L'invention porte sur un filtre double pour l'air comprimé, dans lequel il y a deux filtres (3) placés en parallèle et un système de valves (2, 4) pour diriger l'air comprimé vers un filtre choisi (3). Ce système de valves comprend des valves d'entrée (2) pour diriger l'air comprimé depuis l'entrée (1) vers le filtre choisi (3) et un système de contre-valves (4) pour diriger l'air comprimé du filtre choisi vers la sortie d'air comprimé choisie (5.1). Le système de contre-valves comprend une chambre (8) à bille formée dans la structure du logement, avec des conduits d'entrée (14) aux extrémités et un conduit de sortie (5) au centre. Une bille (9) est prévue pour fermer le conduit d'entrée (14) sur lequel il n'y a pas de pression. La chambre à bille comprend un élément filtrant (10) d'un type connu et dans la zone centrale duquel se trouve un canal de sortie (annulaire) qui reçoit le flux de sortie allant vers le conduit de sortie (5).
