Abstract: 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.
