Abstract

INVENTION CONCERNANT LE FREINAGE DES VEHICULES. ENSEMBLE DE MAITRE-CYLINDRE RENFORCE POUR ACCROITRE L'ACTION DE LA PEDALE. LA TIGE 38 DE SORTIE DU RENFORCATEUR 2 EST RELIEE AU PISTON PRIMAIRE 23 D'UN MAITRE-CYLINDRE 1 TANDEM ET UN RESSORT 39 LOGE DANS LE RENFORCATEUR SOLLICITE LE PISTON PRIMAIRE AINSI QUE LA TIGE DE SORTIE VERS L'ARRIERE. UNE SEULE BUTEE FORMANT JOINT ANNULAIRE 31 S'OPPOSE AU PISTON PRIMAIRE RETRACTE. LES PISTONS 23 ET 24 DU MAITRE-CYLINDRE SONT ECARTES PAR UN RESSORT 32 ET RELIES PAR UNE LIAISON 28, 29, 30 A MOUVEMENT A VIDE. APPLICATION A LA FABRICATION DE DISPOSITIFS DE FREINAGE REQUERANT PEU DE REGLAGES.INVENTION RELATING TO THE BRAKING OF VEHICLES. REINFORCED MASTER CYLINDER ASSEMBLY TO INCREASE PEDAL ACTION. THE OUTPUT ROD 38 OF THE REINFORCER 2 IS CONNECTED TO THE PRIMARY PISTON 23 OF A TANDEM MASTER CYLINDER 1 AND A SPRING 39 HOUSED IN THE REINFORCER REQUESTS THE PRIMARY PISTON AS WELL AS THE OUTPUT ROD TO THE REAR. A SINGLE STOP FORMING AN ANNULAR SEAL 31 OPPOSES THE RETRACTED PRIMARY PISTON. THE PISTONS 23 AND 24 OF THE MASTER CYLINDER ARE SPACED BY A SPRING 32 AND CONNECTED BY A LINK 28, 29, 30 WITH VACUUM MOVEMENT. APPLICATION TO THE MANUFACTURING OF BRAKING DEVICES REQUIRING LITTLE ADJUSTMENTS.
