Abstract
Device for counteracting imbalance in a rotary body and automatically restoring it to a balanced condition. The device comprises a fluid-filled bore in which a throttling member moves freely, which transmits the pressure differentials developed about the axis of rotation during rotation of the body to a balancing mass movable in chambers disposed about the bore to displace the balancing mass a distance proportional to the pressure differentials and is effective upon the balancing mass to restore the body to balanced condition.
