Abstract

VALVE DE COMMANDE HYDRAULIQUE A ACTIONNEMENT ELECTROMAGNETIQUE EQUIPEE D'UNE VALVE PILOTE ET DESTINEE A COMMANDER DES ORGANES UTILISATEURS A SIMPLE EFFET, PAR EXEMPLE DES EMBRAYAGES DE MACHINES AGRICOLES, L'ORGANE UTILISATEUR COMMUNIQUANT AU MOYEN DE LA VALVE PILOTE SOIT AVEC UN RESERVOIR SOIT AVEC UN CONDUIT D'AMENEE D'HUILE SOUS PRESSION. DANS LE CORPS 1 DE LA VALVE DE COMMANDE EST PREVU UN PISTON FORMANT SOUPAPE 2 QUI EN CAS D'ACTIONNEMENT DE LA VALVE PILOTE 4 PEUT ETRE SOULEVE DE SON SIEGE A L'ENCONTRE DE LA FORCE D'UN RESSORT, L'ESPACE CONTIGU AU PISTON 2 DU COTE ELOIGNE DU SIEGE DE SOUPAPE 35 COMMUNIQUANT AVEC UN EVIDEMENT 24 D'UN TIROIR DE DISTRIBUTION 17 PAR L'INTERMEDIAIRE D'UN CANAL 40 QUI, AU MOYEN DE SOUPAPES 25, 29 ACTIONNEES PAR POUSSOIR, PEUT ETRE MIS EN COMMUNICATION AVEC LE CONDUIT DE RACCORDEMENT 23 DU RESERVOIR OU AVEC UN GENERATEUR DE FLUIDE SOUS PRESSION.ELECTROMAGNETICALLY ACTUATED HYDRAULIC CONTROL VALVE EQUIPPED WITH A PILOT VALVE AND INTENDED TO CONTROL SINGLE-ACTING USER ORGANS, FOR EXAMPLE OF AGRICULTURAL MACHINE CLUTCHES, THE USER ORGIN COMMUNICATING BY MEANS OF THE PILOT VALVE OR WITH A RESERVOIR SOFTWARE. PRESSURIZED OIL SUPPLY DUCT. IN BODY 1 OF THE CONTROL VALVE, A PISTON FORMING VALVE 2 IS PROVIDED WHICH, IN THE EVENT OF ACTUATION OF THE PILOT VALVE 4, CAN BE LIFT FROM ITS SEAT AGAINST THE FORCE OF A SPRING, THE SPACE CONTIGUATED TO THE PISTON 2 FROM THE SIDE REMOTE FROM THE VALVE SEAT 35 COMMUNICATING WITH A RECESS 24 OF A DISTRIBUTION DRAWER 17 THROUGH A CHANNEL 40 WHICH, BY MEANS OF VALVES 25, 29 TAPPET ACTUATED, CAN BE COMMUNICATED WITH THE CONNECTION DUCT 23 OF THE TANK OR WITH A PRESSURIZED FLUID GENERATOR.
