Abstract
A fluid balancing ring includes a plurality of partitions forming a circular array of sub-chambers around its circumference. A valve is associated with each of the partitions and is movable in response to the centrifugal force of the rotating balance ring from a closed position preventing fluid communication through the partitions to an open position permitting fluid communication through the partitions. A spring urges the valve to its closed position.
