Abstract
Ce circuit fluidique de freinage (26, 28) comprend : - un circuit (38) d'alimentation d'au moins un cylindre de roue (30, 32, 34, 36) en fluide de freinage, - un accumulateur haute pression (40) stockant le fluide de freinage à une pression contrôlée, - un circuit de décharge (42) dans lequel le fluide de freinage est à une pression inférieure à la pression contrôlée, et - une vanne de commande (44) pour mettre le circuit d'alimentation (38) en communication sélectivement avec l'accumulateur haute pression (40) et avec le circuit de décharge (42), - une ligne de contournement (90) reliant le circuit d'alimentation (38) à l'accumulateur haute pression (40) en parallèle de la vanne de commande (44), et - une vanne de sécurité (92) montée sur la ligne de contournement (90) et configurée pour être dans une configuration bloquante lorsqu'elle est alimentée en électricité et pour basculer dans une configuration passante en cas de coupure de son alimentation en électricité.
