Abstract
Appareil d'asservissement du mécanisme de commande d'un frein à ressort, comportant un dispositif destiné à interrompre et rétablir automatiquement le fonctionnement de ce mecanisme. Cet appareil comprend une valve pilote 26-33 qui comporte un ressort 28 de fermeture et un diaphragme 29 soumis à la pression du cylindre de frein. Cette valve ne permet l'application de la pression du cylindre de frein de service au mécanisme de commande du frein à ressort que lorsque cette pression correspond à un freinage maximal de service. Un dispositif de commande comporte un diaphragme 43 dont une face est soumise à la pression du cylindre de frein et dont l'autre face est soumise à la pression du mécanisme de commande. Application : freinage des véhicules ferroviaires.
