Abstract
A braking system (S) for braking a rotor ( ) relative to a stator ( C, ′C), said system comprising two series of brake disks ( ) secured respectively to the stator and to the rotor and disposed in a disk enclosure ( ). The system further comprises a brake piston device ( ) urged continuously in the braking direction by resilient return means ( ). The piston device is urged in the brake release direction by feeding a brake release chamber ( ) with fluid, and it is urged in the braking direction by feeding a braking chamber ( ) with fluid. The braking system includes a cooling device for cooling the brake disks ( ) by means of fluid flow, which device is provided with a cooling duct ( ) branching from the brake release duct ( ) which feeds the brake release chamber ( ) and communicating with the disk enclosure ( ). It is provided with means ( ) for limiting the quantity of cooling fluid tapped by the cooling duct ( ) from the brake release duct ( ).
