Hydrodynamic converter

A hydrodynamic converter having a working chamber for forming a hydrodynamic working medium circuit, the hydrodynamic converter comprising:

• at least one pump wheel;
• at least one turbine wheel;
• and
• at least one guide wheel, the at least one pump wheel, the at least one turbine wheel and the at least one guide wheel being positioned in the working chamber, wherein working medium flows through the at least one pump wheel centrifugally or centrifugally-diagonally and the working medium flows through the at least one turbine wheel centripetally or centripetally-diagonally, the at least one turbine wheel having an inlet grate edge, the at least one pump wheel having an inlet grate edge, the inlet grate edge of the of the at least one turbine wheel having a smaller or equal radius than the inlet grate edge of the at least one pump wheel relative to an axis of rotation of the pump wheel and the turbine wheel,
• the at least one guide wheel including a first guide wheel provided in the working chamber upstream from the at least one pump wheel in a direction of flow of the working medium, the first guide wheel being arranged for purely centrifugal or diagonal-centrifugal flow of the working medium therethrough.
