Abstract
In a hydrodynamic torque converter, a secondary circulation which is provided for the cooling of the hydraulic fluid in the primary circulation chamber, and when there is a lockup clutch also for the actuation of this lockup clutch, runs through a stator support structure which comprises an overrunning clutch unit. One or more passage channels are provided in the locking rings of the overrunning clutch unit which provide the flow path through the stator support structure.
