The invention relates to a dynamic balancing device applicable to the dynamic balancing of the rotors or other bodies rotating about a fixed axis, and used to eliminate the dynamic unbalances caused by the design or manufacturing deficiencies and to damp the non-uniformities of the drive duty, on one hand, and applicable to stabilizing a rotation axis identifying a fixed direction in the space, and used for gyroscope type systems with a view to eliminating the direction deviations of the rotation axis thereof, on the other hand According to the invention, the device in a first embodiment is provided with non-miscible liquids ( 2 and 3) having different densities, supplied in a toroidal conduit (1), which is attached and centred on the axis of the rotor to be equilibrated or on the rotation axis identifying the fixed direction According to the invention, the device in another embodiment is provided with a circular channel (d) machined in the rotor body (4) and coaxial with a rotation axis (g) thereof or with the axis defining the fixed direction, the circular channel (d) which contains the non-miscible liquids (5 and 6) being sealed with a sealing gasket (7) pressed by a ring nut (8)
