Abstract

INVENTION CONCERNANT LE FREINAGE DES VEHICULES. ENSEMBLE D'ACTUATEUR HYDRAULIQUE POUR SYSTEME DE FREINS HYDRAULIQUES, QUI COMPREND UN ENSEMBLE DE MAITRE-CYLINDRE ACTIONNE PAR PEDALE QUI INCLUT UN PISTON SE DEPLACANT DANS UN PREMIER ALESAGE CYLINDRIQUE DANS UN BOITIER POUR METTRE SOUS PRESSION DU FLUIDE DANS UN PREMIER VOLUME DE PRESSION ET UNE VALVE DE COMMANDE POUR COMMANDER LA COMMUNICATION ENTRE UNE ENTREE, DESTINEE A ETRE RELIEE A UNE SOURCE DE FLUIDE HYDRAULIQUE SOUS PRESSION, ET UNE SORTIE, DESTINEE A ETRE RELIEE A UN CIRCUIT DE FREINAGE, LA VALVE DE COMMANDE POUVANT ETRE ACTIONNEE EN REPONSE AU FLUIDE SOUS PRESSION DANS LE PREMIER VOLUME DE PRESSION. APPLICATION A LA REALISATION DE FREINS PRESENTANT NOMBRE D'AVANTAGES, NOTAMMENT QUANT AU COUT ET A LA COMPLEXITE.INVENTION RELATING TO THE BRAKING OF VEHICLES. HYDRAULIC ACTUATOR ASSEMBLY FOR HYDRAULIC BRAKE SYSTEM, WHICH INCLUDES A PEDAL-ACTUATED MASTER CYLINDER ASSEMBLY WHICH INCLUDES A PISTON MOVING IN A FIRST CYLINDRICAL BORE IN A BOX TO PRESSURE FLUID IN A FIRST PRESSURE AND VOLUME CONTROL VALVE FOR COMMANDING THE COMMUNICATION BETWEEN AN INPUT, INTENDED TO BE CONNECTED TO A SOURCE OF HYDRAULIC FLUID UNDER PRESSURE, AND AN OUTPUT, INTENDED TO BE CONNECTED TO A BRAKE CIRCUIT, THE CONTROL VALVE CAN BE ACTIVATED IN RESPONSE TO THE FLUID UNDER PRESSURE PRESSURE IN THE FIRST VOLUME OF PRESSURE. APPLICATION TO THE REALIZATION OF BRAKES PRESENTING A NUMBER OF ADVANTAGES, ESPECIALLY AS TO COST AND COMPLEXITY.
