Abstract:
An axial fan includes a motor, an impeller and a hub of the impeller for connecting to a shaft of the motor. A bottom wall of the hub has a central portion, and an outer annular portion connected to the central portion by an intermediate portion defined by a plurality of blades arranged radially and angularly distributed about an axis of rotation. The blades are elasto-plastic blades and are able to prevent the impeller from moving axially parallel to the axis, moving radially perpendicular to the and a bending of the impeller with movements normal to the plane in which the mean surface of the impeller itself lies. The blades allow a movement with torsional bending around the axis to allow the damping of the resonance frequencies of the assembly formed by the impeller-shaft-rotor.

Claim (Index 7):
The fan according to  claim 1 , wherein between the bottom wall of the hub and a front wall of the motor there is a distance, each blade having its transversal dimension substantially equal to the distance, the difference being merely sufficient to allow the rotation of the hub without sliding on the front wall of motor.
