Abstract

L'INVENTION CONCERNE UN ACCUMULATEUR A RESSORT, NOTAMMENT POUR ACTIONNEMENT DE FREIN. CET ACCUMULATEUR COMPREND UN RESSORT D'ACCUMULATION 7 S'APPUYANT SUR UN POT 5 S'ETENDANT A L'INTERIEUR DU RESSORT DE MEME QU'UN COMPOSANT 2 SOLIDAIRE DU CARTER 1. UN PISTON DE MISE EN CONTRAINTE 11 ACTIONNE PAR DU FLUIDE ENVOYE DANS LA CHAMBRE 12 EST DISPOSE A L'INTERIEUR DU COMPOSANT 2 ENTRE UNE PAROI 8 DE CELUI-CI ET UN FOND 9 DU POT 5. UN POUSSOIR D'ACTIONNEMENT 18 TRAVERSE LE PISTON ET COMPORTE UN MECANISME DE VERROUILLAGE A BILLES 19, 20, 21, 22, 23 VERROUILLANT LE POUSSOIR AU PISTON. CE MECANISME EST LIBERABLE 25, 26 MANUELLEMENT OU HYDRAULIQUEMENT. L'INVENTION S'APPLIQUE AUX ACCUMULATEURS A RESSORT POUR FREINS DE VEHICULES AUTOMOBILES.THE INVENTION RELATES TO A SPRING ACCUMULATOR, IN PARTICULAR FOR BRAKE ACTUATION. THIS ACCUMULATOR INCLUDES AN ACCUMULATION SPRING 7 BASED ON A POT 5 EXTENDING INSIDE THE SPRING AS WELL AS A COMPONENT 2 SOLID WITH THE CRANKCASE 1. A STRAINING PISTON 11 ACTIVATED BY FLUID SENT IN CHAMBER 12 IS PROVIDED INSIDE COMPONENT 2 BETWEEN A WALL 8 OF THIS AND A BOTTOM 9 OF THE POT 5. AN ACTUATION PUSHBUTTON 18 CROSSES THE PISTON AND INCLUDES A BALL LOCKING MECHANISM 19, 20, 21 , 22, 23 LOCKING THE PUSH-BUTTON TO THE PISTON. THIS MECHANISM IS RELEASABLE 25, 26 MANUALLY OR HYDRAULICALLY. THE INVENTION APPLIES TO SPRING ACCUMULATORS FOR MOTOR VEHICLE BRAKES.
