A hydrodynamic brake which comprising a stator (1), a rotor (2), a toroidal space (7) defined by the stator (1) and rotor (2), a medium intended to be supplied to the toroidal space (7) when the hydrodynamic brake is activated, a first pipe circuit (35) which allows transfer of the medium from the toroidal space (7), and a second pipe circuit (37) which allows transfer of the medium from a storage space (34). The second pipe circuit (37) incorporates a valve arrangement (24, 27) intended to be controlled by the pressure in the first pipe circuit (35) so that the medium in the second pipe circuit (37) is led to the toroidal space (7) when there prevails in the first pipe circuit (35) a pressure which indicates that the brake is activated, and to the first pipe circuit (35) when there prevails in the first pipe circuit (35) a pressure which indicates that the brake is not activated. <IMAGE> |
