Abstract
A dynamic balancer for an automatic washer includes an annular hollow first chamber. A first fluid is held within the first chamber and only partly fills the first chamber. An annular hollow second chamber is disposed adjacent to the first chamber and includes a plurality of objects disposed therein which are movable along the chamber. A second fluid is also held in the second chamber and, in combination with the solid bodies, only partly fills the second chamber. The first fluid in the first chamber produces a first balancing characteristic of the dynamic balancer. The movable objects within the second chamber produce a second balancing characteristic of the, dynamic balancer. The second fluid held in the second chamber also produces a third balancing characteristic of the dynamic balancer.
