<p>A speed dependent response control balancing device of the present invention provides control of vibrations in a rotatable member such as a rotatable basket (10) of a washing machine. The balancing device (20) has two compartments including an annular ball race (22) and a reservoir (24). A plurality of balls (26) are positioned within the annular ball race (22) and move within the ball race to counteract the imbalance of the basket. A varying amount of viscous fluid (40) is delivered from the reservoir into the ball race depending on a rotational speed of the balancing device. Accordingly, the reaction or 'quickness' of the response of the balls within the ball race changes with the rotational speed of the balancing device to provide quick response during a start-up period and slower response at high rotational speeds.</p> |
