Abstract

PERFECTIONNEMENT DANS LEQUEL LES SOUPAPES DE DISTRIBUTION D'AIR COMPRIME SONT DES SOUPAPES DE COMMANDE DE PRESSION ET OU DES BLOCS DE CYLINDRES TRANSFORMENT L'ENERGIE PNEUMATIQUE EN ENERGIE HYDRAULIQUE. COMME DANS LE BREVET PRINCIPAL, TROIS ELECTROVALVES PILOTES 11, 12, 13, A TROIS VOIESDEUX POSITIONS, SONT BRANCHEES DANS LES TUBULURES 8, 9, 10 ET SURVEILLENT LES LIAISONS 14, 15, 16 VERS LES SOUPAPES PRINCIPALES 17, 18, 19. DANS LES TUBULURES 9 ET 10, ON A INTERCALE, AVANT LES CYLINDRES DE FREIN 3 ET 4 DES ROUES 5 ET 6, DES BLOCS 37, 38 CONSTITUES CHACUN D'UN SERVO-CYLINDRE 39, 39 ET D'UN MAITRE-CYLINDRE 40, 40.PERFECTION IN WHICH COMPRESSED AIR DISTRIBUTION VALVES ARE PRESSURE CONTROL VALVES AND OR BLOCKS OF CYLINDERS TRANSFORM PNEUMATIC ENERGY INTO HYDRAULIC ENERGY. AS IN THE MAIN PATENT, THREE PILOT ELECTROVALVES 11, 12, 13, WITH THREE-WAY, TWO POSITIONS, ARE CONNECTED INTO TUBING 8, 9, 10 AND MONITOR LINKS 14, 15, 16 TO MAIN VALVES 17, 18, 19. IN THE TUBING 9 AND 10 ARE INTERCEDED BEFORE THE BRAKE CYLINDERS 3 AND 4 OF WHEELS 5 AND 6, BLOCKS 37, 38 EACH CONSISTING OF A SERVO-CYLINDER 39, 39 AND A MASTER CYLINDER 40, 40 .
