Abstract

Soupapes de commande pour véhicule pouvant être actionnées separément Chaque soupape de commande 5, 6 comprend un obturateur 7 coopérant avec un siège 8 et commandant une des deux sorties 9, un premier ressort 10 sollicitant normalement l'obturateur en contact sur le siège. Un organe d'actionnement 14 pour chaque soupape de commande de frein est couplé à une pédale correspondante et à l'obturateur de la soupape par une liaison à course morte. Application au circuit de freinage hydraulique pour véhicules agricoles ou similaires.
