ABSTRACT:
Disclosed is a fluid friction clutch which comprises an input shaft, a primary disk connected to the shaft, and a secondary drive part, i.e., the clutch housing. The primary disk rotates in a work chamber arranged in the clutch housing and includes a reserve chamber in its interior. A fluid stream, which circulates between the work chamber on the secondary side and the reserve chamber on the primary side, is controlled via a valve attached to the primary disk. The valve is actuated via a tappet arranged coaxially in the input shaft. The orifice of the valve is arranged on the end face of the primary disk, and the associated valve closure element is located in the interior of the reserve chamber. An overflow orifice is present on the circumference of the primary disk in conjunction with a baffle, whereby pumping of the fluid from the work chamber into the reserve chamber is achieved. This fluid friction clutch is used, preferably, as the fan drive means for a radiator in motor vehicles.
