Abstract

Selon l'invention, la soupape de commutation 11 ou 12 possède un piston 17 portant des éléments obturateurs 16, 18 et maintenant normalement l'un, 18, des éléments obturateurs en position de fermeture d'une des deux arrivées de conduite de freins 9, 10. Ce piston, servant au déplacement des éléments obturateurs, peut être déplacé légèrement, tout en maintenant l'arrivée de conduite de frein considérée fermée par l'élément obturateur 18, par des variations de pression dans la conduite de frein 10 qui est alors déterminante pour la commande par pression du piston 17.According to the invention, the switching valve 11 or 12 has a piston 17 carrying shutter elements 16, 18 and now normally one, 18, of the shutter elements in the closed position of one of the two brake line inlets 9 , 10. This piston, used to move the shutter elements, can be moved slightly, while maintaining the arrival of the brake line considered closed by the shutter element 18, by pressure variations in the brake line 10 which is then decisive for the pressure control of piston 17.
