Abstract

DISPOSITIF DE REGLAGE DU DEBIT. IL COMPREND UN ORIFICE F A SECTION VARIABLE CONSTITUE PAR UN SIEGE 35 ET UN POINTEAU 36. LA PERTE DE CHARGE DANS CET ORIFICE COMMANDE UNE VALVE DE DECHARGE C. LA POSITION DU POINTEAU PAR RAPPORT AU SIEGE EST DETERMINEE PAR LA VALEUR DE LA PRESSION ETABLIE D'UN COTE 43 DE CE POINTEAU. CETTE PRESSION EST REGLEE PAR UN ELECTRO-AIMANT 47 QUI PLACE UN PILOTE 40 DANS UNE POSITION DETERMINEE PAR RAPPORT A UN PASSAGE 41 FORME DANS LE POINTEAU. APPLICATION NOTAMMENT AUX SYSTEMES DE COMMANDE HYDRAULIQUE.
