Abstract

PURPOSE: To spin air efficiently in the circumferential and axial direction of a diffuser at even velocity by displacing left and right impeller blades by half a pitch which are crossed with each other to make one round outlet.
CONSTITUTION: Each pair of impeller blades 1a, 1b on the left and right sides of a hub 3 is placed as shown which are displaced by half a pitch P/2. These left and right impeller blades displaced are crossed with each other on the side of a diffuser 5. The end of a hub 3 near the blade chip is cut off 7 due to cross of the both blades 1a, 1b. This constitution of the impeller blades 1a, 1b removes jet/ wake so that air can be spinned at even velocity in the circumferential direction of the diffuser.
