Abstract
A filtering pulley having a hub adapted to be fixed to a rotating shaft, a pulley ring mounted coaxial and rotationally free on said hub, and at least one elastic assembly interposed between the hub and the pulley ring and a damper for damping the relative oscillations between the hub and the pulley ring is disclosed. The damper has a first damping level for relative rotations between the hub and the pulley ring which are smaller than a predetermined angle and a second damping level, which is greater than the first level, for relative rotations between the hub and the pulley ring which are larger than the predetermined angle.
