ABSTRACT:
A hydraulic eddy brake has a rotor and a stator both forming an eddy chamber. Liquid supply conduits lead to the center of the eddy chamber. The rotor shaft is sealed relative to the housing formed by the stator. The sealing is accomplished by noncontacting sealings. Leakage liquid is discharged to respective chambers located between the bearings and the eddy chamber proper. A gap is provided between the shaft and the housing. This gap is connected with the center of the eddy chamber through a liquid feedback which may include an intermediate chamber and respective liquid feedback conduits whereby the pressure at the point of leakage is minimized. Such brakes are used as absorption dynamometers to measure torque.
