Abstract

EL INYECTOR TIENE UN CUERPO HUECO (12) CON UNA BOQUILLA; UNA VALVULA MEDIDORA (24); Y UN ELECTROIMAN (26) PARA ACTIVAR UN INDUCIDO (27) QUE CONTROLA LA VALVULA (24). EL ELECTROIMAN (26) SE ALOJA DENTRO DE UNA CUBIERTA (54) QUE FORMA PARTE INTEGRAL DE UNA PARED TERMINAL (57) EQUIPADA CON UN ACCESORIO DE DESCARGA (32) DE LA VALVULA (24). EL INDUCIDO (27) SE GUIA MEDIANTE UN ELEMENTO DE GUIA (66) QUE TIENE UNA ROSCA (69) QUE SE ACOPLA A UNA ROSCA CORRESPONDIENTE (18) DEL CUERPO (12) HUECO, INDEPENDIENTEMENTE DEL MONTAJE DEL CUERPO (33) DE LA VALVULA (24). ENTRE EL ELECTROIMAN (26) Y EL ELEMENTO GUIA (66) SE HA DISPUESTO UN SEPARADOR (82) DE TAMAÑO MODULAR PARA AJUSTAR EL ESPACIO ENTRE EL INDUCIDO (27) Y EL ELECTROIMAN (26). LA CUBIERTA (54) SE ADAPTA AL CUERPO HUECO (12) MEDIANTE UNA TAPA (62) QUE SE ENROSCA EN EL CUERPO HUECO (12).
