Abstract

a. Frein à air comprimé, à action indirecte, agissant en fonction de la charge. b. Frein caractérisé en ce que le second piston 40 chargé par la pression du cylindre de frein, est susceptible d'être appuyé dans la direction de charge de la pression du cylindre de frein, par un piston annulaire 41 qui s'appuie par le ressort 51 ci-dessus, sur le troisième piston 45 et en ce que la course du piston annulaire 41 et celle du troisième piston 45, sont limitées, d'une part, dans la direction de charge de la pression de cylindre de frein et, d'autre part, dans la direction opposée, respectivement, par des butées 60, 61. c. L'invention s'applique au freinage ferroviaire.at. Compressed air brake, indirectly acting, acting according to the load. b. Brake characterized in that the second piston 40 loaded by the pressure of the brake cylinder, is able to be pressed in the direction of load of the pressure of the brake cylinder, by an annular piston 41 which is supported by the spring 51 above, on the third piston 45 and in that the stroke of the annular piston 41 and that of the third piston 45, are limited, on the one hand, in the load direction of the brake cylinder pressure and, on the other hand, in the opposite direction, respectively, by stops 60, 61. c. The invention applies to railway braking.
