PURPOSE:To eliminate a stay vane and form a machine to smaller size as a whole, by arranging fixed guide vanes at an equal distance to the internally peripheral part of a casing and arranging an equal number of movable guide vanes between the fixed guide vanes then interlocking said movable guide vanes. CONSTITUTION:Fixed guide vanes 11 and movable guide vanes 12 are arranged to the internally peripheral part of a casing 10 on the same circumference. The guide vanes, fundamentally of movable type, are partially formed to a fixed type, and the fixed guide vanes 11 are arranged to the internal periphery of the casing 10 at an equal distance, while the movable guide vanes 12 are arranged in an equal quantity between said vanes 11, then these movable guide vanes 12 are formed interlocking. The movable guide vane 12, when closed, is contacted to a shutter surface of the respectively neighboring movable guide vane 12, simultaneously contacted also to the fixed guide vane 11. |
