Abstract
Disclosed is a railway braking system including a braking device provided with a body, a single piston that can move with respect to the body to act on a brake linkage, and delimiting, together with the body, a pressure chamber supplied by a pressure medium source for placing the piston in a rest position where the linkage applies no force on a braking member of a railway vehicle, first and second seals housed between a first section of the piston and the body, and third and fourth seals housed between a second section of the piston and the body; the first and third seals being configured to form a primary sealing of the pressure chamber and the second and fourth seals being configured to form a secondary sealing of the pressure chamber.
