Abstract

PURPOSE: To facilitate air flow along surface and annular air flow by restraining generation of swirl caused by compressed air flow in such a way that a slant is provided at each corner part where a rear surface of each blade and a circumferential surface of a runner are crossed.
CONSTITUTION: When a runner 2 is rotated at high speed by driving a motor, annular air flow is generated within a casing. In this case generation of swirl in each corner part 7 caused by compressed air flow is restrained as a slant 10 is provided at each corner part 7, where a rear surface 6 of each blade 3 and a circumferential surface 2a of the runner 2 are crossed. Thus, air flow along surface is facilitated air pressure in an outlet part is increased, whereby efficiency of a pump is improved.
