  • Rotary compressor with stepped cover contour
    Patent number: 5304033
    Abstract: A compressor assembly includes a housing, and a rotatable impeller within the housing which includes a hub and blades extending from the hub. A ring circumscribes the leading edge of the blades, and cooperates with a groove in the housing to define a clearance therebetween which is larger than the clearance between the connecting edge of the blades and a corresponding conforming portion of the housing. This permits free flow of gas around the ring to enhance the operating range of the compressor wheel. The ring also stiffens the blades, permitting the thickness of the hub to be reduced, thereby further enhancing the operating range of the compressor wheel.
