Abstract

Système de frein électrohydraulique (30) comprenant: un maître-cylindre (32), une pompe (34) dont le débit est transmis à une soupape (50) de régulation de pression, un moteur (36) destiné à mettre en rotation la pompe, une soupape d'isolation (42) destinée à raccorder sélectivement le maître-cylindre et/ou la pompe à un ou des cylindres de frein (44), ainsi qu'un générateur de signal (40) destiné à activer la pompe. Une soupape de régulation de pression est reliée entre le maître-cylindre et la pompe afin de réguler la pression de débit de la pompe à un niveau déterminable proportionnel à la pression générée par le maître-cylindre, et pour ménager un chemin permettant de vider le ou les cylindres de frein dans un réservoir au cours d'intervalles de diminution de la pression du maître-cylindre. Le système peut également comprendre une ou des soupapes (90) de débit excédentaire destinée(s) à empêcher que le réservoir ne soit vidé par la pompe dans le cas d'un mauvais fonctionnement du système. Divers modes de réalisation de la soupape de régulation prévoient une protection supplémentaire à mode de panne.
