<p>A storage space (3) for fluid is located within the outer circumference of the drive rotor (11). First and second flow paths (11b, 11c) link this space with the coupling region. The drive rotor has a flow resistance (11a) at the outer circumference, between the first and second flow path. A control opens and closes at least one of the flow paths. The contact area is proportional to the quantity of the hydraulic liquid in the clutch range. The viscous fluid comprises: hydraulic oil, silicone oil, a silicone, synthetic or natural polymer compounds or hydrocarbon compounds.</p> |
