Abstract
PURPOSE:To improve efficiency by making an inner apace of a vane wheel in a form of gradual contraction centripetally for providing vanes in spiral from suction opening to delivery direction. CONSTITUTION:A vane wheel 2 is made up of a base shaft 3 and vanes 4 and funnel-shaped in outer form. Vanes 4 are formed in such that the suction edges of the same are in a form arranged three layers of spiral holes divided with brades from the base shaft 3 to the front edge of the vane wheel 2 in broad width, and the same gladually contract toward backward in spiral with retaining the form and fixed solidly, centrifugal edges to the inner wall of the vane wheel 1 and inner side edges to the base shaft 3. Fluid is absorbed through rotation of the base shaft 3 and sent through compressing passage composed of the vane wheel 2 and the base shaft 3 with increasing the compressed pressure. Therefore, it can be intended to get high efficiency.
