Abstract
Interference of a leakage vortex flow generated at the tip end side of the full blade with the leading edge of the splitter blade is avoided and high pressure ratio and enhanced efficiency can be achieved. A throat of am impeller is formed so that a distance from a leading edge of a rear side full blade on the rear side of the rotation direction of the compressor to a front side full blade adjacent to the rear side full blade is minimized, and the leading edge of the splitter blade is placed in a fluid flow streaming along the flow passage between the mutually adjacent full blades, on the downstream side of a leakage vortex line formed to connect the middle location of the throat to the leading edge of the front side full blade.
