Abstract

See full text

There is provided a hydrodynamic retarder including a bladed rotor and a bladed stator jointly forming a working chamber to be filled with working medium and discharged therefrom, a working medium container receiving working medium, and a control pressure application system pressurizing the working medium with a control pressure medium to displace the working medium from the working medium container into the working chamber to set a desired braking torque. A centrifugal separator separating the working medium from the control pressure medium, the centrifugal separator is connected in a flow-conductive manner to an outlet of the working medium container for the control pressure medium to be pressurized with the control pressure medium, the centrifugal separator is driven by the pressure of the control pressure medium, and the working medium container is assembled from at least two shells, where the first and/or the second shell encloses the centrifugal separator.
