Abstract

Dispositif limiteur destiné à équiper un circuit de freinage hydraulique de véhicule et comprenant une entrée et une sortie pour transmettre la pression hydraulique à partir du maître-cylindre à au moins un frein de roue et un équipement régulateur destiné à limiter la pression hydraulique transmise. Le dispositif limiteur comporte un organe détecteur 48 pouvant occuper une première position qui empêche le fonctionnement de l'équipement régulateur de pression et une seconde position qui permet le fonctionnement de cet équipement, et un second équipement régulateur disposé entre l'entrée 26 et la sortie 29 et qui permet d'ouvrir une autre voie par laquelle la pression peut être transmise chaque fois qu'un seuil préétabli de différence de pression entre les pressions d'entrée et de sortie est atteint.Limiting device intended to equip a hydraulic vehicle braking circuit and comprising an input and an output for transmitting the hydraulic pressure from the master cylinder to at least one wheel brake and a regulating device intended to limit the transmitted hydraulic pressure. The limiting device comprises a detector member 48 which can occupy a first position which prevents the operation of the pressure regulating equipment and a second position which allows the operation of this equipment, and a second regulating equipment arranged between the inlet 26 and the outlet. 29 and which makes it possible to open another channel by which the pressure can be transmitted whenever a pre-established pressure difference threshold between the inlet and outlet pressures is reached.
