Abstract
A hydrodynamic coupling has an impeller and a turbine wheel that together form a toroidal working chamber. Viewed as an axial section through the hydrodynamic coupling the working chamber has a circular or essentially circular cross-section with a convexity in the axial direction on the circumference in the radially outer area of said turbine wheel and/or in the radially inner area of said impeller.
