Zusammenfassung:	A balancing apparatus (20; 30; 40) for a rotary element (21; 31; 41) is provided and includes a central hub portion (210; 310; 410) and radial elements (211; 311; 411) extending outwardly from the central hub portion (210; 310; 410). The balancing apparatus (20; 30; 40) includes a conduit (321, 322; 420, 421, 422) extending along the radial elements (211; 311; 411) via the central hub portion (210; 310; 410); a mass movable within the conduit (321, 322; 430, 421, 422); and a mass balancing system (22; 32; 42) which directs a movement of the mass within the conduit (321, 322; 430, 421, 422).
