ABSTRACT:
A fluid friction clutch is provided having an intermediate wall, disposed in a housing and separating the clutch fluid supply or storage space and the clutch fluid working space, with a plurality of overflow openings therein at circumferentially spaced locations. The clutch fluid primarily enters the working space from the storage space through a controllable supply inlet opening in the intermediate wall. The supply inlet is thermostatically controlled by a bi-metal element. A rotating clutch disk is provided in the working space, and at least one clutch fluid return bore is provided in the intermediate wall in the region adjacent the outer circumference of the clutch disk. These return bores provide return guidance for clutch fluid into the storage space.
