Abstract

L'invention concerne un dispositif de commande hydraulique de frein à tambour comprenant un boîtier définissant un alésage dans lequel un piston est monté coulissant. Une cloison, montée de façon mobile entre le piston et un orifice d'entrée, est sollicitée normalement contre un épaulement défini dans l'alésage par un ressort disposé dans une chambre secondaire définie entre la cloison et le piston. Une restriction est prévue pour faire communiquer la chambre secondaire avec l'orifice d'entrée lorsque la cloison est en butée contre l'épaulement, de façon à réguler la baisse de pression dans la chambre secondaire. Application au freinage des véhicules.
