Abstract

LOS MOVIMIENTOS DE APERTURA Y DE CIERRE DE UNA VALVULA DE UN INYECTOR LA QUE CIERRA Y ABRE TEMPORALMENTE LOS ORIFICIOS DE DESCARGA QUE SE COMUNICAN CON LA CAMARA DE COMBUSTION DE UN MOTOR DE COMBUSTION INTERNA ES CONTROLADA POR LA PRESION DEL COMBUSTIBLE EN UNA CAMARA DE CONTROL (350) SITUADA EN UN EXTREMO DEL PISTON DE LA VALVULA INYECTORA (336). EL COMBUSTIBLE SALE DE DICHA CAMARA DE CONTROL (350) A TRAVES DE ORIFICIOS (348, 352, 366, 364) CUANDO UNA VALVULA (76) ES LEVANTADA DE SU SITIO (70) PARA PERMITIR LA APERTURA DE LA VALVULA INYECTORA. SI SE VUELVE A COLOCAR EL VASTAGO DE LA VALVULA (76) EL CUERPO DE LA VALVULA INTERMEDIO (332) SE SALDRA TEMPORALMENTE DE LA SUPERFICIE DE ASIENTO (354) HACIENDO QUE LA CAMARA DE CONTROL (350) SE VUELVA A LLENAR RAPIDAMENTE CON EL COMBUSTIBLE FLUYENDO A TRAVES DE LOS ORIFICIOS (360) CONECTADOS A UN ORIFICIO DE ENTRADA (358). SE CONSIGUE UN CIERRE FIRME DE LA VALVULA.
