Hydrodynamic machine, in particular hydrodynamic converter

A hydrodynamic machine, comprising:

• at least one bladed pump impeller;
• at least one bladed turbine impeller;
• a working chamber to be filled with a working medium and in which said at least one bladed pump impeller and said at least one bladed turbine impeller are disposed in order to hydrodynamically transmit torque and/or drive power from said at least one bladed pump impeller to said at least one bladed turbine impeller;
• a working medium inlet for supplying the working medium into said working chamber;
• a working medium outlet for discharging the working medium out of said working chamber;
• a bypass for the working medium that branches off from said working medium inlet;
• a control valve disposed in said working medium inlet or in said bypass, said control valve used to change a working medium quantity flowing into said working chamber by adjusting a flow cross-section for the working medium flowing through said control valve;
• and
• said control valve is connected to said working medium inlet and/or said working medium outlet and actuated such that the flow cross-section of said control valve is variably adjusted in dependence on a working medium pressure in said working medium inlet and a working medium pressure in said working medium outlet.
