PURPOSE:To provide an axial flow fluid machine which can be actuated in a flow region of wide range containing a low flow region without decreasing maximum efficiency and partial load efficiency. CONSTITUTION:For instance, in an axial flow compressor having moving blades 3 set up onto the periphery of a hub 2 integrally rotated with a rotary shaft 1, stationary blades 5 set up onto the internal periphery of a casing 4 and an annular flow path 6 constituted between the casing 4 and the hub 2, fluid (B) at a speed higher than fluid (A) 7, flowing in the annular path 6, is jetted toward on a blade surface in a point end part of the moving blade 3 from a jet port 8 via a pressure pipe 10 and an introducing pipe 9 by the compressor 11 when the rotary shaft 1 is rotated. |
