Abstract
Soupape comportant un piston de réglage à membrane, dont la surface active varie en fonction de la course, par appui des membranes sur des supports. La soupape de frein 1 a deux circuits I et II. Ce dernier comporte un régulateur de freinage 3 dont la pression est envoyée aux cylindres de frein 4 et 5 de l'essieu arrière 2. Cette pression parvient à la soupape 8 de rapport de pression, dans le circuit I. La soupape reçoit également la pression de la soupape 1. Elle possède un piston de commande 22 et un piston de réglage 23. Le piston 22 porte un élément de fermeture 26 et un siège 28, l'autre siège 29 de la soupape 27 étant solidaire du carter. Le piston 23 porte des membranes 36, 37 qui s'appuient plus ou moins sur des supports 38, 39 selon la position du piston 23.
