Abstract

Soupape double de commande de freins à air. Le carter de la soupape comporte coaxialement et successivement, de l'extrémité de manoeuvre à l'extrémité d'échappement d'air, une chambre de distribution de pression contenant un piston, une chambre contenant une soupape normalement appliquée sur son siège, une chambre de relayage de pression reliée à la première chambre, une chambre de distribution de pression contenant un deuxième piston et une chambre contenant une soupape normalement fermée, les surfaces des pistons et des soupapes étant telles qu'une pression initiale s'établisse dans les première et troisième chambres avant l'établissement d'une pression dans la quatrième chambre. Application aux circuits de freinage pour camions ou tracteurs de remorque.
