Abstract

PURPOSE:To obtain a low pressure of substantial vacuum by providing an airfoil cylinder to be rotated which has, on its periphery, openings facing in the direction opposite to the rotational direction and flared at their ends so that air in the outer part is coaxially expanded. CONSTITUTION:Fluid in an airfoil cylinder B rotates counterclockwise when the airfoil cylinder B is rotated counterclockwise, resulting in centrifugal force being generated, so that the fluid gradually moves from an inlet opening at the center A to outlet openings at C and is then discharged. Since the outside parts of the outlet openings, at C, which face in the direction opposite to the rotational direction of the airfoil cylinder B is flared like Conidae shape, the outside air is moved in the direction indicated by arrows. Therefore, the outside air can hardly flow into the rear side of the outlet openings so that low pressure portions are produced, while the fluid in the airfoil cylinder B is more easily discharged from the outlet openings, thereby low pressure of substantial vacuum is obtained.
