Abstract

A hydrodynamic torque converter, especially for motor vehicles, which is equipped with a pump wheel, a turbine wheel and a guide wheel and with adjustable cascade at least at one of these wheels, preferably at the guide wheel; each blade of such wheel is thereby rotatably supported and is automatically adjustable against a spring force by the torque exerted by the circulating flow of the hydraulic medium.
