Abstract
A three-channel torque converter in which an additional wall is mounted, thereby creating a third space which hydraulically connects the end of the plates that faces away from the turbine to a third channel. This third space ensures that an exchange flow of oil in a region of the hydrodynamic components (impeller, turbine, stator), of an optional damper, and of the lockup clutch is always restricted to flow across the plates of the lockup clutch. This provides high-performance cooling of the plates in the slip mode.
