Title: HYDRODYNAMIC RETARDER
Abstract:
The invention relates to a hydrodynamic retarder comprising a bladed rotor and a bladed stator which together form a working chamber that can be filled with or emptied of a working medium, comprising a working medium container for receiving working medium which is not currently located in the working chamber, comprising a control pressure application system for supplying a control pressure medium to the working medium contained in the working medium container such that more or less working medium is displaced out of the working medium container into the working chamber in order to set a desired braking torque, and comprising a centrifugal separator (6) for separating the working medium from the control pressure medium. The centrifugal separator (6) is fluidically connected to a working medium container outlet for the control pressure medium so as to be pressurized with the control pressure medium, and the centrifugal separator is driven by the pressure of the control pressure medium.
