Abstract

VALVULA DE PRESION, QUE SE MONTA EN EL CONDUCTO DE TRANSPORTE (7, 7''), QUE VA DESDE UNA BOMBA DE INYECCION DE COMBUSTIBLE HASTA UNA VALVULA DE INYECCION DE COMBUSTIBLE (8) Y QUE PRESENTA UN MIEMBRO DE CIERRE DE LA VALVULA (21) QUE SE ABRE EN EL SENTIDO DE TRANSPORTE, QUE ESTA DOTADO CON UN REBORDE DE RETORNO (35). PARA CONSEGUIR UNA INYECCION HOMOGENEA, ESPECIALMENTE UN DESARROLLO HOMOGENEO DE LA INYECCION CON UNA CARGA DADA SOBRE EL NUMERO DE REVOLUCIONES SE CONTROLA LA PROPORCION DE APERTURA DE LA SECCION TRANSVERSAL DE COMUNICACION EN EL MIEMBRO DE CIERRE DE VALVULA (21) DE TAL FORMA QUE SE HA PREVISTO INMEDIATAMENTE A CONTINUACION DEL REBORDE DE RETORNO (35), UN REBORDE DE CONTROL CON EL MISMO DIAMETRO (36), QUE PRESENTA UNA ESCOTADURA (38) EN SU PERIFERIA. ESTA QUEDA LIMITADA POR UN CANAL DE PASO (20) QUE CONDUCE HASTA EL MIEMBRO DE CIERRE DE VALVULA (21) Y PRESENTA UNA SECCION TRANSVERSAL DE PASO DEFINIDA, QUE SE ENCUENTRA ESPECIALMENTE EN EL ORDEN DE MAGNITUD DE LA SECCION TRANSVERSAL DEL CONDUCTO DE TRANSPORTE.
