Abstract
A hydrodynamic retarder with a stator blade wheel and a rotor blade wheel whose blades together fill the work chamber for working liquid. Slot shaped inlet openings permit entrance of working liquid to the working chamber. The inlet openings are located at the radially inner region of the rotor blade wheel toward the retarder shaft. Slot shaped outlet openings permit outlet of working fluid. The outlet openings are at the radially outer region of the rotor blade wheel. The slots are oriented to follow the incline of the blades of the rotor blade wheel. The inlet slots each trail a respective rotor wheel blade while the outlet slots each lead that blade in the movement direction of the rotor blade wheel. Particular thicknesses of blades and particular angular sizes of the inlet and the outlet slot openings are disclosed.
