Abstract

Cette invention concerne un dispositif de commutation électrique destiné à une valve hydraulique. Il est prévu un système de commutation de sécurité comprenant un contacteur, un relais et une valve, qui est alimenté à partir de la bobine d'excitation de la génératrice du véhicule. Lorsque cette génératrice est entraînée par le moteur du véhicule, la tension d'excitation engendrée ferme le circuit de commutation et actionne la valve pour établir une communication entre l'accumulateur de pression et l'appareil ou les appareils d'utilisation Quand le moteur est arrêté, la chute de tension d'excitation au-dessous d'une valeur déterminée ouvre ce circuit. Un agencement de ce type est utilisable notamment sur les tracteurs.
