Abstract
A fluid friction clutch which assigns the supply chamber to the primary disk connected to the drive shaft, so that the centrifugal forces acting on the oil are determined by the drive speed and not by the clutch housing speed. The inflow and outflow, to and from the working chamber, are controlled via an electromagnet arrangement, in the end positions, to allow the inflow orifice to remain closed when the return flow line is open, and vice versa.
