Abstract

Ce dispositif est du type comprenant une soupape principale commandée par air comprimé et faisant office de soupape d'admission et d'échappement dans une conduite de frein, ainsi qu'une soupape pilote commandée par voie électromagnétique en fonction de signaux de capteurs. Selon l'invention, la soupape pilote (électrovanne 30) est à plus de deux positions et peut être commandée par l'intermédiaire d'un dispositif de commutation, comprenant l'excitation de la bobine 28 avec l'une de deux intensités de courant électrique.
