Hydrodynamic machine, particularly hydrodynamic retarder, has bladed primary wheel rotating over rotating axis of hydrodynamic machine and bladed secondary wheel stationary or rotating over rotating axis of hydrodynamic machine

摘要

The hydrodynamic machine has a bladed primary wheel (20) rotating over a rotating axis (10) of the hydrodynamic machine and a bladed secondary wheel stationary or rotating over the rotating axis of the hydrodynamic machine. Blades (21,21') or a torus wall of the primary wheel or the secondary wheel are designed or arranged such that a blade chamber (22) has a flowing cross section opposite to the flowing section of an adjacent blade chamber (22').
