Abstract

EL PROPOSITO DE LA INVENCION ES EL PROPORCIONAR, EN UNA VALVULA (1) DE INYECCION DE COMBUSTIBLE DE FUNCIONAMIENTO ELECTROMAGNETICO PARA UN MOTOR DE COMBUSTION INTERNA, UNA DISPOSICION DE GRAN PRECISION DE LA APERTURA DE SALIDA, SOPORTE DE VALVULA Y CILINDRO GUIA RELATIVOS UNO CON OTRO, INCREMENTANDO ASI LA PRECISION DE FUNCIONAMIENTO Y REDUCIENDO EL DESGASTE DE LA VALVULA DE INYECCION DE COMBUSTIBLE. ESTO SE ADQUIERE POR MEDIO DEL HECHO DE QUE EL CUERPO DEL ASIENTO DE LA VALVULA (5) INCLUYE EL CILINDRO GUIA (7), EL SOPORTE DE LA VALVULA (8) Y LA APERTURA DE SALIDA (9), SITUADAS INTEGRALES CON Y DENTRO DEL CUERPO DE ASIENTO DE LA VALVULA CERCA DE SU EJE. LA INVENCION ESTA PENSADA EN PARTICULAR PARA UNIDADES DE INYECCION DE COMBUSTIBLE EN VEHICULOS A MOTOR.THE PURPOSE OF THE INVENTION IS TO PROVIDE, IN AN ELECTROMAGNETIC OPERATING FUEL INJECTION VALVE (1) FOR AN INTERNAL COMBUSTION ENGINE, A HIGH PRECISION DISPOSAL OF THE OUTLET OPENING, SUPPORT OF A VALVE AND ANOTHER GUIDE. , SO INCREASING THE PRECISION OF OPERATION AND REDUCING THE WEAR OF THE FUEL INJECTION VALVE. THIS IS ACQUIRED THROUGH THE FACT THAT THE VALVE SEAT BODY (5) INCLUDES THE GUIDE CYLINDER (7), THE VALVE SUPPORT (8) AND THE OUTLET OPENING (9), LOCATED INTEGRALLY WITH AND WITHIN THE VALVE SEAT BODY NEAR ITS AXLE. THE INVENTION IS DESIGNED IN PARTICULAR FOR FUEL INJECTION UNITS IN MOTOR VEHICLES.
