| 20080223172 | Hollow Shaft with at Least One Balancing Weight, and Process for Producing It - The invention relates to a method for fixing at least one balancing weight ( | 09-18-2008 |
| 20130133475 | ANNULAR AUTO-BALANCING MECHANISM - An annular auto-balancing mechanism consisting of an annular shaped housing that is filled with fluid of specific viscosity, characterized in that its balancing weights rotate around a series of circularly set supporting axes of balancing weights, which allows for the construction of an annular shaped mechanism, which, in turn, allows the mechanism to be installed on the front side of a drum for unobstructed opening and closing of the door of a washing machine, on the one hand, and maximal utilization of the mechanism's volume, on the other hand. | 05-30-2013 |
| 20130174690 | BALL BALANCER AND WASHING MACHINE HAVING THE SAME - Disclosed is a ball balancer that increases a rate of balls in ball detention portions and restricts aggravation of unbalance caused by balls outside of the ball detention portions. When a rotation speed of a rotator is less than a first rotation speed, the ball detention portion allows the ball moved from a rolling face to be detained therein and to allow the ball therein to come into contact with the released ball outside thereof to prevent separation of the released ball from the rolling face. Anti-separation portions are provided to come into contact with the released balls outside of the ball detention portions to prevent separation of the released balls from the rolling face. When the rotation speed is greater than the first rotation speed, the ball detention portion allows separation of the ball therein to the rolling face by centrifugal force applied thereto. | 07-11-2013 |
| 20160160421 | LAUNDRY TREATING APPLIANCE WITH A DYNAMIC BALANCER - A dynamic balancer device for mounting to and balancing a rotatable drum in a laundry treating appliance. The dynamic balancer device comprises an enclosed annular housing having a radial circumferential wall, a plurality of internal baffles in the enclosed annular housing and a fluid disposed in the annular race and movable therein. | 06-09-2016 |
