ABSTRACT:
An optimum axial distance is secured by varying the distance between a nozzle blade and a moving blade along the length of a nozzle blade (11). The nozzle blades (11) are curved so that a middle portion of each nozzle blade has a section (b2) dislocated in the flowing direction of a fluid which flows through the fluid passage relative to the root section (b3) and the tip section (b1) of the blade with respect to a circumferential direction and an axial direction. Outlet flow angle of the nozzle is varied with distance along the blade length to vary optimum axial distance properly.
