Abstract
Filtering pulleys have a hub, which is designed to be fixed to a rotary shaft rotating around an axis (A), and a crown, which is coaxial to said hub. The filtering pulley includes a filtering assembly operatively interposed between the hub and the crown and a housing integral to the crown and carried so that the housing can freely rotate relative to the hub by means of support means. The filtering assembly defines a space and has elastic means housed inside the space in a movable manner, and has actuator means configured to cooperate in contact with the elastic means. The actuator means is a single piece together with a tubular portion of the hub and the housing cooperating in contact with the radial inner surface of the crown.
