Abstract

UNA BOQUILLA DE INYECCION DE COMBUSTIBLE COMPRENDE UN ELEMENTO DE VALVULA ACCIONADO POR PRESION DE COMBUSTIBLE (14) DEL TIPO QUE SE ABRE HACIA DENTRO QUE ES MOVIL POR LA ACCION DEL COMBUSTIBLE BAJO PRESION ALEJANDOSE DESDE UN ASIENTO DE VALVULA PARA PERMITIR QUE EL COMBUSTIBLE FLUYA DESDE UNA ENTRADA DE BOQUILLA (16) A TRAVES DE UNA SALIDA (22). MONTADO SOBRE EL CUERPO DE BOQUILLA HAY UNA VALVULA DE EVACUACION (23) QUE CUANDO FUNCIONA PERMITE QUE SE ESCAPE COMBUSTIBLE DE LA ENTRADA DE BOQUILLA DE MANERA A REDUCIR LA PRESION DE COMBUSTIBLE APLICADA AL ELEMENTO DE VALVULA DE BOQUILLA. LA VALVULA DE EVACUACION SE ACCIONA POR MEDIOS HIDRAULICOS (42, 43).
