<p>The invention concerns a device for balancing a rotary element of machines subjected to an unbalance, consisting of a mobile part formed by a supporting body (9) integral with the rotary element (5) shaft at one end and comprising three valves (10) placed at 120° from one another on a common diameter, a pivoted connection (13) coupled to a duct supplying the balancing fluid and a fixed part consisting of a circular stop (15) integral with the machine support (1) and positioned in the rotary element (5) axis when it is balanced or inoperative. Said stop (15) has in its central part a bossing opposite the rods controlling the valves (18) whereon the latter can rest when the rotary element is off balance. The invention is particularly designed to balance washing machine drums in centrifuging phase.</p> |
