The invention relates to a hydrodynamic torque converter with a lock-up clutch. The converter circuit is charged with converter fluid via two lines which may be reversed. A further liquid path which allows cooling of the piston of the lock-up clutch on its back via throttle channels is provided in parallel with the pressure line for opening the lock-up clutch.
