Abstract
PURPOSE: To prevent generation of a rotating noise of an impeller by removing a tongue part from a casing.
CONSTITUTION: A clearance between a casing rear guider 3 and an impeller periphery 11 is formed near a flow conversion point 83 where a closs flow 8, at the farthest point from a vortex 5, in a cross flow 7 induced inside an impeller 1 is let to a suction flow 81 and then converted into a discharge flow 82. The casing is made up of a rear guider 3 alone, and has no tongue part in it, which substantially removes generation of a rotating noise of the impeller primarily by the interference of an external flow 6 surronding the vortex 5 with the tongue.
