Abstract
SE PROPONE UNA VALVULA DE INYECCION PARA INSTALACIONES DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA, QUE SIRVE PARA EL INYECTADO DE COMBUSTIBLE EL DEL TUBO ASPIRANTE. LA VALVULA DE INYECCION COMPRENDE UNA CARCASA DE LA VALVULA (1), EN LA QUE SE ENCUENTRA UN NUCLEO (4), CON EL QUE COOPERA UN INDUCIDO (5). CON LA CARCASA DE LA VALVULA (1) SE HA UNIDO UN CUERPO DE TOBERA (15) CON UNA SUPERFICIE DE ASIENTO DE VALVULA (17), CON LA QUE COOPERAN UN ASIENTO HERMETICO (21) DE UNA AGUJA DE VALVULA (6) GUIADA POR MEDIO DE UNA PORCION DE GUIA (30, 31) EN UN TALADRO DE GUIA (16) DE CUERPO DE TOBERA (15), DOTANDOSE A LA PORCION DE GUIA (31) QUE SE ENCUENTRA, AGUAS ARRIBA, A CONTINUACION DEL ASIENTO HERMETICO (21), CON TALADROS DOSIFICADORES (47). ESTOS TALADROS DOSIFICADORES (47) SE HAN DISPUESTO INCLINADAMENTE DE FORMA QUE CUANDO LA VALVULA ESTA ABIERTA, GENERAN UNA TORSION, CON LO QUE SE CONSIGUE UNA BUENA PREPARACION DEL COMBUSTIBLE. SEGUN LA INVENCION DESEMBOCA CADA TALADRO DOSIFICADOR (47) EN LA PROXIMIDAD INMEDIATA, ES DECIR LIGERAMENTE AGUAS ARRIBA DEL ASIENTO HERMETICO (21).
