Abstract

La presente invención se refiere a un sistema de purga de filtro para purgar los vapores de combustible volátiles reconectados desde un filtro hasta el colector de admisión de un motor de combustión interna, que comprende una válvula de solenoide de purga de filtro que tiene una entrada, una salida y un medio de válvula que está dispuesto en un pasaje entre la entrada y la salida e impone una restricción seleccionada al flujo a través del pasaje, de acuerdo con una señal de control eléctrica suministrada al solenoide de la válvula, y una válvula normalmente cerrada y accionada por vacío que tiene una entrada, una salida y un medio de válvula que está dispuesto en un pasaje entre la entrada y la salida mencionadas en último término y abren el pasaje mencionado en último término para flujo únicamente a valores de una entrada de señal de vacío a un orificio de control de la válvula normalmente cerrada y accionada por vacío que exceda un cierto valor mínimo, primeros medios de conducto que incluyen un medio de orificio, para conectar la entrada y la salida de la válvula de solenoide de purga del filtro a un filtro y un colector de admisión de motor respectivamente, unos segundos medios de conducto para conectar la entrada y la salida de la válvula normalmente cerrada y accionada por vacío a ese filtro y colector de admisión de motor respectivamente, y terceros medios de conducta que conectan el orificio de control de la válvula normalmente cerrada y accionada por vacío a una toma que está dispuesta en los primeros medios de conducto mencionados, entre el medio de orificio y la válvula de solenoide de purga del filtro.
