Abstract

The driving half-coupling or pump and driven half-coupling or turbine are fitted with radial vanes and form an annular working space. The coupling has a device, which measures the driving torque and regulates the flow of liquid into the coupling so as to reduce the vol. of liq. when the transmitted torque exceeds a predetermined value and to increase it when the torque falls below that value. Such couplings are of value in the electric motor drive of very long conveyor belts, and of very large ventilating fans.
