Abstract
A fluid clutch includes a housing having an interior that can be filled with fluid, an output element that can be rotated relative to the housing, a first friction surface arrangement coupled to the housing, a second friction surface arrangement coupled to the output element, and means for bringing the first and second friction surface arrangements into frictional engagement. A fluid circulation arrangement in the housing causes fluid to circulate around the friction surfaces without requiring a simultaneous exchange of fluid to and from the interior.
