Abstract

EN LAS VALVULAS CONOCIDAS, AL SOLDAR EL DISCO PERFORADO DE INYECCION AL CUERPO DEL ASIENTO DE VALVULA, SE PRODUCEN UNAS TENSIONES QUE AFECTAN A LA REDONDEZ DE LA SUPERFICIE DEL ASIENTO DE VALVULA HASTA TAL PUNTO QUE CUANDO LA VALVULA ESTA CERRADA PUEDE OCURRIR UN DERRAME MINIMO DE COMBUSTIBLE. SE BUSCA EVITAR ESTA INFLUENCIA NEGATIVA NO DESEADA SOBRE LA REDONDEZ DE LA SUPERFICIE DEL ASIENTO DE VALVULA, OCASIONADA POR TAL SOLDADURA, PERFECCIONANDOSE ADEMAS LA HERMETICIDAD DE LA VALVULA CUANDO ESTA CERRADA. AL ESTAR PREVISTA UNA RANURA (18) EN LA CARA FRONTAL INFERIOR (17) DEL CUERPO DEL ASIENTO DE VALVULA (16) QUE MERMA LA TRANSMISION TERMICA ENTRE LA COSTURA DE SOLDADURA (31), ENTRE EL DISCO PERFORADO DE INYECCION (21) Y EL CUERPO DEL ASIENTO DE VALVULA (16), LAS TENSIONES ORIGINADAS TERMICA Y MECANICAMENTE SON ABSORBIDAS POR UN BORDE DE SOLDADURA (33), MIENTRAS QUE LA SUPERFICIE DEL ASIENTO DE VALVULA (29) SE MANTIENE LIBRE DE TALES TENSIONES. LA VALVULA DE INYECCION DE COMBUSTIBLE ES ESPECIALMENTE APTA PARA LAS INSTALACIONES DE INYECCION DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA COMPRESORAS DE MEZCLA Y CON ENCENDIDO DE CHISPA.
