Abstract
L'invention concerne une unité de commande de pression pour installation de freinage hydraulique. Cette unité comprend dans un boîtier 1 une soupape de réduction de pression 3, 8, 9 du côté d'une chambre de sortie 7 d'un premier circuit de freinage et une soupape de limitation de pression 10, 12, 14 du côté d'une chambre de sortie 13 d'un second circuit de freinage. Un piston intermédiaire 15 d'équilibrage des pressions peut venir s'appuyer sur une butée 21 du boîtier et comprend un alésage 16 avec un épaulement 17 dans lequel est disposé un piston auxiliaire 18, 18' en deux parties. L'invention s'applique aux systèmes de freinage de véhicules automobiles.
