Abstract

ES CONOCIDA UNA VALVULA DE INYECCION DE COMBUSTIBLE CON UNA PLANCHA MATRIZ DE SILICIO DISPUESTA EN LA DIRECCION DE UN ASIENTO DE VALVULA QUE PRESENTA UNA ABERTURA DE PULVERIZACION EXTENDIDA EN LA DIRECCION DE LA CORRIENTE. MEDIANTE ESTA ABERTURA DE PULVERIZACION SE PRODUCE UN CHORRO PARA CUERDA CON UNA RELATIVA PULVERIZACION DE MALA CALIDAD DEL COMBUSTIBLE , DE MODO QUE NO SE GARANTIZA LA CONFIGURACION DE UNA MEZCLA DE COMBUSTIBLE-AIRE MAS AMPLIAMENTE HOMOGENEA. LA NUEVA PLANCHA MATRIZ DE SILICIO (23) PRESENTA EN UNA DE LAS SUPERFICIES DE ASIENTO DE VALVULA (13) DE LA DIRIGIDA CARA SUPERIOR (35) AL MENOS UNA ESCOTADURA (39) QUE CADA VEZ INTERFIERE EN PARTE CON UNA ABERTURA DOSIFICADORA EXTENDIDA (41) HASTA LA CARA INFERIOR (31) DE LA PLANCHA MATRIZ (23). SEGUN LA INVENCION LA PLANCHA MATRIZ (23) PERMITE LA FORMACION DE CHORROS EN ABANICO, DE MODO QUE SE OBTIENE UNA PULVERIZACION MUY FINA DEL COMBUSTIBLE CEDIDO. LA FORMACION DE LAS ESCOTADURAS LONGITUDINALES (39) Y LAS ABERTURAS DE PULVERIZACION (41) MEDIANTE GRABADO DE ACIDO PERMITEN UNA ALTA PRECISION CON UN ACABADO DE ESCASO COSTE. LA PLANCHA MATRIZ Y LA VALVULA DE INYECCION DE COMBUSTIBLE SON ESPECIALMENTE APROPIADAS PARA INSTALACIONES DE INYECCION DE VEHICULOS DE ENCENDIDO MEZCLADOS POR COMPRENSION.
