Abstract

VALVULA ANTEPUESTA DE SEGURIDAD EN DISPOSITIVOS DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA. ESTA VALVULA SE LOCALIZA EN EL MOTOR ENTRE EL ACUMULADOR DE COMBUSTIBLE A PRESION Y EL ESPACIO DE RECEPCION DE COMBUSTIBLE, EN LAS PROXIMIDADES DE LA AGUJA DE INYECCION. LA ENTRADA (26) Y LA SALIDA (27) DE LA VALVULA DE SEGURIDAD SE VEN CORTOCIRCUITADAS MEDIANTE LA RANURA ANULAR (34), A TRAVES DE LOS CONDUCTOS DE ENTRADA (29) Y SALIDA (32), CUANDO EN LA COMPRESION LA PRESION REINANTE EN EL CILINDRO (21) ES TAL QUE VENCE LA ACCION DEL MUELLE (57). AL DISMINUIR LA PRESION EN EL CILINDRO (21) LA RANURA ANULAR SE DESPLAZA HACIA LA DERECHA, INCOMUNICANDO LA ENTRA (26) Y LA SALIDA (27).
