Abstract

SERVO-DISTRIBUTEUR DE COMMANDE DE PRESSION DANS UN CIRCUIT FLUIDIQUE. LE SERVO-DISTRIBUTEUR COMPREND UN ENSEMBLE DE VALVES 11, 13 COMPORTANT UN ELEMENT MOBILE 14, TEL QU'UN TUYAU D'INJECTION POUVANT ETRE DEPLACE EN REPONSE A UN SIGNAL D'ENTREE, LES VALVES FOURNISSANT UN FLUIDE DE SORTIE DONT LA PRESSION EST FONCTION DE LA POSITION DE L'ELEMENT MOBILE 14, ET UN MECANISME DE REACTION 12 AGISSANT SEULEMENT D'UN COTE D'UN ELEMENT DE COMMANDE DE REACTION 23 TEL QU'UN LEVIER AFIN DE LE FAIRE DEPLACER EN OPPOSITION A UNE FORCE DE POUSSEE, PRODUITE PAR UN RESSORT 24, SOUS L'ACTION DU FLUIDE SORTANT, UN MOUVEMENT DE CET ELEMENT DE COMMANDE 23 PRODUISANT UN MOUVEMENT DE REACTION CORRESPONDANT DE L'ELEMENT 14, LA VALVE 11 POUVANT SE PRESENTER SOUS LA FORME D'UNE VALVE PILOTE COOPERANT AVEC UNE VALVE D'ADMISSION 13. APPLICATION AUX COMMANDES HYDRAULIQUES.PRESSURE CONTROL SERVO-DISTRIBUTOR IN A FLUID CIRCUIT. THE SERVO-DISTRIBUTOR INCLUDES A SET OF VALVES 11, 13 INCLUDING A MOVABLE ELEMENT 14, SUCH AS AN INJECTION HOSE THAT CAN BE MOVED IN RESPONSE TO AN INPUT SIGNAL, THE VALVES PROVIDING AN OUTPUT FLUID WHOSE PRESSURE IS FUNCTIONED OF THE POSITION OF THE MOBILE ELEMENT 14, AND A REACTION MECHANISM 12 ACTING ONLY ON ONE SIDE OF A REACTION CONTROL ELEMENT 23 SUCH AS A LEVER IN ORDER TO MOVE IT IN OPPOSITION TO A PUSHING FORCE, PRODUCED BY A SPRING 24, UNDER THE ACTION OF THE EXIT FLUID, A MOVEMENT OF THIS CONTROL ELEMENT 23 PRODUCING A CORRESPONDING REACTION MOVEMENT OF THE ELEMENT 14, THE VALVE 11 CAN BE IN THE FORM OF A PILOT VALVE COOPERATING WITH A INTAKE VALVE 13. APPLICATION TO HYDRAULIC CONTROLS.
