Abstract
In order to achieve a mechanically simple, reliable, and independent balancing device for compensation of an unbalance in a rotating body without the need for a supply of a fluid from outside the rotor nor an adjustment of nozzles to insert the fluid, the balancing device features a feed device with a fluid-containing cavity arranged stationary in or on the body of rotation, which has outlet openings emerging into the balancing chambers, which are to be closed and opened by a movable closing body depending upon the occurrence of an unbalance. Specifically, on or in the body of rotation reside at least three balancing chambers uniformly distributed in the peripheral direction, each of which is connected by an inlet opening to a feed device for a fluid with a specific gravity that is greater than that of air, and with a regulator for regulated feeding of fluid from the feed device into the balancing chambers.
