Abstract: Filtering pullies with a hub adapted to be fixed to a rotating shaft, a crown mounted coaxially and rotationally free on the hub, at least one elastic group arranged circumferentially with respect to the hub and the crown and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown are disclosed. The pulley has a dust protection system configured to isolate the at least one elastic group with respect to the external environment and to provide an axial force generating a damping to the movement between the hub and the crown.

Abstract: Filtering pullies with a hub adapted to be fixed to a rotating shaft, a crown mounted coaxially and rotationally free on the hub, at least one elastic group arranged circumferentially with respect to the hub and the crown and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown are disclosed. The pulley has a dust protection lip carried integrally by said hub and configured to slide, in tight manner, with respect to an element integral with said crown. The dust protection lip is a labyrinthine sealing lip.
