Abstract

EN LAS VALVULAS CONOCIDAS CONTROLADAS ELECTROMAGNETICAMENTE LA AGUJA DE LA VALVULA CONSISTE EN UNA SECCION DE ARMADURA TUBULAR, UNA SECCION DEL CUERPO DE LA VALVULA TUBULAR Y EN UNA SECCION DE CIERRE DE VALVULA. LA SECCION DE ARMADURA ESTA UNIDA AL PRIMER EXTREMO DE LA SECCION DEL CUERPO DE LA VALVULA POR MEDIO DE UNA SOLDADURA Y LA SECCION DE CIERRE ESTA UNIDA AL OTRO EXTREMO DEL CUERPO DE LA VALVULA POR MEDIO DE UNA SEGUNDA SOLDADURA. ESTE PROCESO DE PRODUCCION ES RELATIVAMENTE CARO Y COSTOSO, PORQUE NECESITA DOS OPERACIONES DE SOLDADURA. EN UNA NUEVA AGUJA DE VALVULA (58), LA PARTE ACTUANTE TUBULAR (31) CONSISTENTE EN UNA SECCION DE ARMADURA (36) Y EN UNA SECCION DE CUERPO DE LA VALVULA (38), ES PRODUCIDA POR UN MOLDEADO A INYECCION SEGUIDO DE UN SINTERIZADO, DE ACUERDO CON EL PROCESO DE MOLDEADO POR INYECCION DEL METAL. LA PARTE ACTUANTE (32) SE UNE DESPUES A LA SECCION DE CIERRE (46) POR MEDIO DE UNA SOLDADURA, DE MODO QUE LA AGUJA DE LA VALVULA (589 PUEDE SER PRODUCIDAS POR UN METODOSIMPLE Y ECONOMICO. ESTA AGUJA DE VALVULA ES ESPECIALMENTE ADECUADA EN SISTEMAS DE INYECCION DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA.
