Abstract

SE PRESENTA UNA VALVULA (5) CONTROLADA POR UNA VALVULA MEDIDORA ELECTROMAGNETICA (41) QUE COMPRENDE UNA CABEZA (49) QUE TIENE UNA CAMARA DE CONTROL (56), UN CONDUCTO DE SUMINISTRO (57) Y UN CONDUCTO DE DRENAJE (58). LA CABEZA TAMBIEN PRESENTA UNA CAVIDAD (67) QUE SE COMUNICA CON EL CONDUCTO DE SUMINISTRO EN LA CUAL UNA PARTE (68) DEL ELEMENTO MOVIL (8, 28) PARA CERRAR EL ORIFICIO DE INYECCION (11) SE DESLIZA DE TAL FORMA QUE ESTRANGULA EL CONDUCTO DE SUMINISTRO DURANTE LA INYECCION. EL CONDUCTO DE SUMINISTRO SE COMUNICA CON UNA CAMARA RECEPTORA (59) SITUADA ENTRE UN ASIENTO (51) DEL CUERPO (6) DE LA VALVULA (5) Y LA SUPERFICIE EXTERIOR DE UN ACCESORIO (54) EN LA CABEZA; Y EL ELEMENTO MOVIL ES EMPUJADO A LA POSICION DE CERRADO MEDIANTE LA ACCION COMBINADA DE LA PRESION EN CADA EXTREMO, Y MEDIANTE UN MUELLE (37) SITUADO CERCA DE LA CAMARA DE INYECCION (19).
