Abstract
The invention relates to a hydrodynamic coupling, especially for a turbocompound system, comprising: a pump wheel; a turbine wheel which forms in combination with a pump wheel a working chamber which can be filled with a working medium. The hydrodynamic coupling in accordance with the invention is characterized in that a mechanical locking device is provided for connecting the pump wheel and the turbine wheel in a torsionally rigid manner, which locking device is in connection with a section of the coupling guiding a working medium such that it closes under a predetermined degree of filling of the working chamber.
