Abstract

Un inyector de combustible incluye una carcasa del inyector, un conjunto de válvula de control de retención dentro de la carcasa del inyector, una retención de operación directa, un desviador de válvula soportado en la carcasa del inyector, y una válvula de protección de funcionamiento en seco atrapada entre el desviador de válvula y la carcasa del inyector. La válvula de protección de funcionamiento en seco limita la expulsión del fluido de accionamiento drenado del inyector de combustible para permitir llenar un volumen de baja presión en el mismo antes de llenar una línea de drenaje de baja presión común a una pluralidad de inyectores de combustible en un sistema de motor de combustión interna.
