Abstract

Ce dispositif est du type comprenant un organe d'évacuation qui est associé à un orifice d'évacuation. Il est caractérisé en ce que les moyens de commande comprennent deux circuits électriques présentant chacun, une interruption entre un point différent pour les deux circuits, et un autre point situé à un niveau inférieur, commun aux deux circuit et situé au dessous du niveau minimal, un organe de commande de l'organe d'évacuation étant par ailleurs interposé sur ces deux circuits de manière que la fermeture de l'interruption du premier circuit provoque la mise en service de cet organe d évacuation, tandis que l'ouverture de celle du second circuit provoque la mise hors service.
