Problems solved by technology

[0003] In wet-running clutch arrangements, the problem is that, after a relatively long idle time, during driving operation, the fluid contained in the housing arrangement partially escapes from the housing arrangement and flows, for example, into a fluid sump in the gearbox.
However, because fluid is generally required to engage the friction clutch areas, a state of inability to transmit torque may occur for a period of time after start of operation due to the lack of possibility of filling the piston cavity and thus engaging the friction clutch areas

Embodiment Construction

[0046] figure 1 In general, 10 denotes a clutch device for operating the drive train of a vehicle. This clutch device 10, which can be used as a starting element, comprises a housing device 12 with a housing shell 14 to be positioned close to the engine, that is to say on the engine side, and a housing shell 14 to be positioned close to the transmission, that is to say on the transmission side. Housing shell 16 . The two housing shells 14 , 16 are fixedly connected to one another, for example by welding, in regions 15 , 17 of which radially outer sides extend one above the other, and together define an interior 18 of the housing arrangement 12 . A clutch device 20 is provided on the engine-side housing shell 14 , by means of which the housing device 12 can be connected for common rotation about an axis of rotation A with a drive shaft (eg a crankshaft of an internal combustion engine), for example by means of a bent plate arrangement or the like. In its radially inner region...
