Abstract

Ce dispositif permet de réguler la pression de freinage en commun pour un ou plusieurs groupes de cylindres de frein de roue d'un véhicule. La conduite de frein 13 menant aux cylindres de frein 3, 4, 5, 6 contient, pour chaque groupe, une soupape 22 à trois voies et deux positions; à chaque cylindre de frein est associée en outre une soupape 21 ou 23 à deux voies et deux positions. Selon l'invention, chaque groupe de cylindres de frein est réparti sur plusieurs essieux 11, 12 situés proches l'un de l'autre. Une soupape supplémentaire à deux voies et deux positions peut être prévue en plus pour chaque groupe afin d'obtenir une commande à trois canaux avec une phase de maintien de pression supplémentaire.This device makes it possible to regulate the braking pressure in common for one or more groups of wheel brake cylinders of a vehicle. The brake line 13 leading to the brake cylinders 3, 4, 5, 6 contains, for each group, a three-way and two-position valve 22; with each brake cylinder is also associated a valve 21 or 23 with two ways and two positions. According to the invention, each group of brake cylinders is distributed over several axles 11, 12 located close to one another. An additional two-way, two-position valve can also be provided for each group in order to obtain a three-channel control with an additional pressure maintenance phase.
