Abstract
A LA VALVULA REGULADORA LA CONTROLA UN ELECTROIMAN (42) QUE TIENE UN NUCLEO FIJO (46), UNA BOBINA (47) Y UNA ARMADURA (43). EL NUCLEO (46) SE FORMA PRESIONANDO Y SINTERIZANDO A CONTINUACION UNA MEZCLA DE UN MATERIAL FERROSO EN POLVO Y UN AGLUTINANTE EPOXI; Y PRESENTA UNA HISTERESIS MAGNETICA Y BAJAS CORRIENTES PARASITAS, DE TAL MODO QUE, PARA UNA CORRIENTE EXCITADORA DADA, SE CONSIGUE UNA MAYOR FUERZA MAGNETICA Y MAS RAPIDAMENTE Y, PARA UNA FUERZA MAGNETICA DADA O FRECUENCIA MAXIMA DE FUNCIONAMIENTO, EL NUCLEO (46) Y/O LA BOBINA (47) PUEDEN SER MENORES.
