  • Liquid-chamber apparatus for active, dynamic balancing of rotating machinery
    Patent number: 5490436
    Abstract: Apparatus performs active, dynamic balancing of a rotating machine by shifting the spatial distribution of an inertial liquid within a body that co-rotates with the rotating shaft of the machine. The body includes chambers, substantially disposed at equal angular intervals, for containing the inertial liquid. The chambers communicate through a channel lying at or beyond the outermost radial position of the outward ends of the chambers. A motive element or elements are provided for impelling the inertial liquid through the channel. The chambers, channel, and motive elements form a sealable system.
