ABSTRACT:
An improved clothes washing machine is provided with a one-piece pulley and fluid balance ring. The fluid ring is integrally formed with the pulley and is cantilevered from the pulley. The fluid ring is thus in an offset vertical plane relative to the belt track of the pulley so as to prevent interference with the pulley belt. The fluid ring includes a plurality of concentric annular fluid chambers each of which are partially filled with fluid to provide a counterbalance to an unbalanced load of clothes in the washing machine. In an alternative embodiment, the fluid ring is integrally formed with the pulley and spaced radially inwardly from the pulley belt track.
