Claims

[Scope of utility model registration request]

The diaphragm includes an annular row of stator vanes held between an outer ring and an inner ring, and an annular row of rotor blades installed on a rotating shaft, and these stator vanes and the annular row of rotor blades are arranged in the axial direction of the rotating shaft. In the axial flow turbine, the stator blades are arranged with a constant gap between the stator vanes, and an inlet chamber is provided upstream of the annular row of the stator blades for guiding the working fluid sent through the inlet pipe to each stator blade. An axial flow turbine characterized in that a chevron-shaped guide portion that gradually decreases in the circumferential direction from the center point of the inlet pipe to the opposite side thereof is provided integrally with the casing in front of the inlet chamber.
