Abstract

Dispositivo de recirculación de una fracción de los gases de escape de un motor de combustión, tomados en el colector de escape, y reinyectados en el colector de adminisión, cuando la temperatura del motor se eleva, caracterizado porque una válvula de depresión, unida a uno de los extremos de conductos, solidarios, por otra parte, de los colectores de admisión y de escape, y que determina su puesta en relación, es accionada por la depresión del carburador, por mediación de una electroválvula, activada a su vez por un contacto, establecido cuando las condiciones de funcionamiento del motor llegan a ser anormales, debido a la combustión de una mezcla demasiado rica, estando activado el citado contacto por la salida del tirador del arrancador.
