Abstract:
1. A hydrodynamic machine, comprising: a first blade wheel including a plurality of blades; and a second blade wheel including a plurality of blades, said first blade wheel and said second blade wheel being opposite one another in such a way that said first blade wheel and said second blade wheel jointly form a toroidal working chamber which is configured for being filled with a working medium in order to hydrodynamically transfer a torque by way of a cycle flow of said working medium in said working chamber from said first blade wheel to said second blade wheel, said first blade wheel configured for rotating about a rotational axis in a direction of rotation, said second blade wheel one of (a) configured for rotating about said rotational axis one of (i) in said direction of rotation of said first blade wheel and (ii) opposite said direction of rotation of said first blade wheel, and (b) being held in a stationary manner, said working chamber including a radially inner wall and a radially outer wall, each of said plurality of blades of each of said first blade wheel and said second blade wheel including a radially inner blade end and a radially outer blade end, said plurality of blades of each of said first blade wheel and said second blade wheel extending in an arc from said radially inner blade end on said radially inner wall of said working chamber to said radially outer blade end on said radially outer wall of said working chamber, said plurality of blades of each of said first blade wheel and said second blade wheel being disposed perpendicularly to a plane which forms a separating gap between said first blade wheel and said second blade wheel and on which said rotational axis stands perpendicularly, said plurality of blades of each of said first blade wheel and said second blade wheel extending in a direction of said rotational axis, said arc having a circular arc shape in a top view of each of said first blade wheel and said second blade wheel in said direction of said rotational axis.
