Braking system for braking a rotor relative to a stator

A braking system comprising first braking means secured to a rotor, second braking means secured to a stator, a brake piston suitable for taking up a brake release position and a braking position in which it urges the first and second braking means into braking cooperation, the system further comprising resilient return means continuously urging the brake piston into its braking position, a braking chamber suitable for being fed with a fluid under pressure to urge the brake piston towards its braking position, a brake release chamber suitable for being fed with fluid under pressure to urge the brake piston towards its brake release position, and control means for controlling feeding said chambers with fluid, the braking chamber and the brake release chamber being interconnected via a link duct serving to generate a flow of fluid in an assisted braking situation in which the braking chamber is connected to a fluid feed duct, while the brake release chamber is connected to a fluid return duct, and the link duct being equipped with means for limiting the flow of the fluid through said link duct at least in the direction going from the brake release chamber to the braking chamber.
