Abstract

LA INVENCION TIENE EL COMETIDO DE MEJORAR LA EXACTITUD DE AJUSTE Y EL FUNCIONAMIENTO DE VALVULAS DE INYECCION DE COMBUSTIBLE Y REDUCIR LOS COSTES DE FABRICACION. PARA UNA VALVULA DE INYECCION DE COMBUSTIBLE (1) OPERABLE ELECTROMAGNETICAMENTE PARA MOTORES DE GASOLINA, LA INVENCION PROVEE UNA DISPOSICION ALTAMENTE EXACTA DEL ORIFICIO DE SALIDA (9) DEL INYECTOR (5) O DEL ASIENTO DE VALVULA (8) Y DE LA VIA DE GUIA (14) ENTRE SI Y MEJORA, CON ELLO, LA EXACTITUD DE FUNCIONAMIENTO Y EL COMPORTAMIENTO ANTE EL DESGASTE DE LA VALVULA DE INYECCION DE COMBUSTIBLE DEBIDO A QUE UN ANILLO GUIA ESPECIAL (7) ESTA SUJETO EN EL ORIFICIO LONGITUDINAL (13) A UNA DISTANCIA RADIAL MEDIANTE UNA UNION SOLDADA (2). LA INVENCION ESTA PREVISTA ESPECIALMENTE PARA VALVULAS DE INYECCION DE COMBUSTIBLE DE MOTORES DE VEHICULOS.THE INVENTION HAS A COMMITTED TO IMPROVE THE ACCURACY OF ADJUSTMENT AND OPERATION OF FUEL INJECTION VALVES AND TO REDUCE MANUFACTURING COSTS. FOR AN ELECTROMAGNETICALLY OPERABLE FUEL INJECTION VALVE (1) FOR GASOLINE ENGINES, THE INVENTION PROVIDES A HIGHLY ACCURATE ARRANGEMENT OF THE INLET HOLE (9) OR THE VALVE SEAT (8) AND THE GUIDE TRACK (14) BETWEEN AND IMPROVES, WITH IT, THE ACCURACY OF OPERATION AND THE BEHAVIOR IN THE FACE OF WEAR OF THE FUEL INJECTION VALVE DUE TO A SPECIAL GUIDE RING (7) IS SUBJECT TO THE LONGITUDINAL HOLE (13) AT A DISTANCE RADIAL THROUGH A WELDED JOINT (2). THE INVENTION IS SPECIALLY INTENDED FOR VEHICLE ENGINE FUEL INJECTION VALVES.
