<p>PCT No. PCT/DK84/00063 Sec. 371 Date Feb. 28, 1985 Sec. 102(e) Date Feb. 28, 1985 PCT Filed Jun. 29, 1984 PCT Pub. No. WO85/00446 PCT Pub. Date Jan. 31, 1985.In an eddy current brake for controlling quantitative flow in a water line and with a brake housing in the shape of lying frustum of a cone with an outlet opening in the narrow end and an inlet opening downwardly on the large end face there is disposed a guide vane opposite the inlet opening within the housing, said guide vane being rotatable about the axis of the housing by means of an exterior adjustment lever between a position in which it closes the inlet, and a position in which it is disposed completely outside the inlet region and thus allows free flow. In intermediate positions the guide vane deflects the in flowing stream of water toward the frusto-conical wall so that the water, when the pressure head exceeds a certain valve, is caused to rotate about the axis of the housing to produce the desired brake effect. This effect can be varied by adjustment of the guide vane. Its deflecting effect permits the inlet spout and outlet spout of the brake housing to be disposed in elongation of each other.</p> |
