ABSTRACT:
A hydrodynamic retarder has a stationary element and a rotary element, each of which has a semi-toroidal cavity with a plurality of blade members disposed therein. The semi-toroidal cavities are presented in facing relation with the blade curvatures being oppositely directed. The blade members each have a fluid flow profile that accommodates constant acceleration of the fluid from entrance to exit.
