ABSTRACT:
A hydrodynamic brake for a vehicle having a stator and a rotor, which each comprise an annular recess and a plurality of vanes which are provided in the respective recess. The rotor rotates in a rotation direction such that a relatively high pressure is created on a first side of the respective vanes of the stator and a relatively low pressure on a second side of each vane of the stator. This pressure difference is used for the supply and the discharge, respectively, of the fluid. A respective supply opening is provided in the stator in the vicinity of the second side of a respective vane and a respective discharge opening is provided in the stator in the vicinity of the first side of a respective vane.
