Abstract

L'invention concerne les distributeurs des appareils de réglage de dérapage. Elle se rapporte à un distributeur dans lequel un moteur couple déplace une ailette 25 entre deux buses 33 et 39 qui fixent ainsi une pression de commande transmise à un distributeur qui règle la transmission à un canal 51 de fluide à une pression de commande soit d'un fluide à une pression mesurée provenant d'un canal 43, soit d'un fluide à la pression de commande provenant d'un canal 57, selon que la pression mesurée est inférieure ou supérieure à la pression de commande. Application à la suppression du dérapage des véhicules au cours du freinage.
