Abstract

UN INYECTOR DE COMBUSTIBLE EN VORTICE A ELEVADA PRESION, QUE COMPRENDE UN ALOJAMIENTO O CUERPO HUECO QUE INCLUYE UNA PLURALIDAD DE CONDUCTOS, AL MENOS UNO DE LOS CUALES ESTA ADAPTADO PARA RECIBIR COMBUSTIBLE A TRAVES DE UNA ENTRADA. EL INYECTOR COMPRENDE TAMBIEN UN CONDUCTO PARA GUIAR EL PISTON, EN RELACION DE ASIENTO, CON EL ASIENTO DE UNA VALVULA, PARA CONTROLAR EL FLUJO DE COMBUSTIBLE A TRAVES DEL ORIFICIO DOSIFICADOR Y UN CONJUNTO DE SOLENOIDE PARA MOVER EL PISTON RESPECTO AL ASIENTO DE VALVULA. EL INYECTOR COMPRENDE ADEMAS UNA CAMARA DE TORBELLINO O VORTICE, PARA ACELERAR ANGULARMENTE EL COMBUSTIBLE, FORMADA EN COOPERACION CON LA PRIMERA SUPERFICIE DEL ASIENTO DE VALVULA. EL INYECTOR COMPRENDE ADEMAS CONDUCTOS PARA QUE EL COMBUSTIBLE PUEDA CIRCULAR ALREDEDOR DE UNA BOBINA ELECTRICA DEL MISMO, PARA ENFRIARLA DE ESE MODO DURANTE LAS OCASIONES EN LAS CUALES EL ORIFICIO DOSIFICADOR SE ENCUENTRA CERRADO. EL INYECTOR INCLUYE ADEMAS CONDUCTOS DENTRO DE LA CAMARA DE TORBELLINO PARA FAVORECER LA RAPIDA FORMACION DE UN MODELO DE PULVERIZACION CONICA TRAS LA APERTURA DEL ORIFICIO DOSIFICADOR.
