Abstract

PURPOSE: To decrease a loss of the diffuser due to the wall face friction, by variably providing a vane mounting angle and keeping a distance of the vaneless diffuser part at constant despite an amount of said mounting angle.
CONSTITUTION: A vane 5 is divided into two as shown by 5A, 5B in the drawing. In the blade end of the vane 5A at the impeller side, a hollow part 12 is provided and a blade end of the vane 5B at the outlet side is telescopically housed in the hollow part 12. While near ends of the vanes 5A, 5B are provided rotating axes 13A, 13B about which centers the respective vanes 5A, 5B can be rotated. If a pinion 10 is rotated from a condition (c) in which the vanes 5A, 5B are combined to an arrow mark direction 15, the vane 5A is shifted to a position (d) while decreasing its mounting angle. Following the above movement, the vane 5B is rotated in such a manner as to be aligned with a mounting angle of the vane 5A while being gradually removed from the hollow part 12 of the vane 5A.
