<p>The device has a pendulum flyweight mounted to move on a support (2). Left sub-paths (131, 132) and right sub paths (141, 142) are respectively provided on edges of the flyweight and the support to damp torsion vibrations corresponding to a periodic function of excitation generated by an engine during a sub-period of engine period. Right sub paths (31, 32) and left sub-paths (41, 42) are respectively provided on the edges to damp torsion vibrations corresponding to another periodic function. The functions have different periods for same rotation speed of the support.</p> |
