摘要

Improvements introduced in the rotor rotary vane fans with circulating fluid of radial, centrifugal, centripetal and/or axial type, including a wheel provided with vanes mounted in a rotatable manner and with a variable orientation angle, characterized in that the force of the centrifugal inertia of the vane or of a mass associated with it, due to the rotation of the wheel, is directed, at least in a sector of rotation of the vane, so that it exerts on it a moment or a pair that has effect to move it from a rest position to an active position.
