Radial-flow turbo machine |
(57) A radial-flow turbo machine comprising an impeller (10) in which the center line
(190) of each moving vane (100) in a cross section perpendicular to the axis of rotation
(500) becomes more distant toward the back surface side (130) of the vane from a radial
straight line (700) passing through the axis of rotation (500) and through an intersection
(600) where the center line (190) of the vane and a hub line intersect as a radius
having the axis of rotation (500) as its center increases.
