Patent ID: 8292569

Claim:
An air regulator, comprising: a housing; a shaft that rotates within the housing; a first air regulation member coaxially coupled to the shaft, the first air regulation member having a plurality of first air flow apertures positioned radially about the shaft at a first radial distance; a second air regulation member coaxially coupled to the shaft, the second air regulation member having a plurality of second air flow apertures positioned radially about the shaft at a second radial distance that is less than the first radial distance; a chamber defined between the first air regulation member and the second air regulation member; an elastic ring positioned within the chamber and configured to centrifugally deform and increasingly block the first air flow apertures; and a rotor coupled to the shaft, the rotor having a plurality of vanes, the vanes defining a plurality of nozzles, each nozzle having a first end and a second end, wherein the first air flow apertures are respectively connected to the first ends of the nozzles to permit fluid flow between the first air flow apertures and the nozzles.
