Abstract

L'invention concerne un ensemble (107 ; 207 ; 307) permettant de commander une conduite d'air comprimé (4) d'une rame de véhicules (101 ; 201 ; 301), comprenant un dispositif de commande (8) et un système de valves (113a ; 113b ; 213a ; 213b ; 313a ; 313b) commandable au moyen d'une instruction de commande (SB.w) du dispositif de commande (8) et formant une sortie (36) vers l'atmosphère. Pour optimiser le freinage de la rame de véhicules, le dispositif de commande (8) est réalisé de manière appropriée pour émettre en tant que valeur d'instruction de commande instantanée une parmi au moins quatre valeurs d'instruction de commande (SBW1, SBW2, SBW3, SBW4) de l'instruction de commande (SB.w). Le système de valves commandable (113a ; 113b ; 213a ; 213b ; 313a ; 313b) est par ailleurs réalisé de manière appropriée pour, sous l'action des différentes valeurs d'instruction de commande, adopter différentes positions (ST1, ST2, ST3, ST4) correspondantes de telle manière que, lorsque le système de soupapes (113a ; 113b ; 213a ; 213b ; 313a ; 313b) est installé, deux tronçons (4.k, 4.k+1; 4.l, 4.l+1; 4.ma, 4.mb) de la conduite d'air comprimé sont soit raccordés, soit séparés, soit ouverts vers l'atmosphère, ou qu'un seul des deux tronçons est ouvert vers l'atmosphère. L'invention concerne également un procédé permettant de commander une conduite d'air comprimé (4) d'une rame de véhicules.
