Document Type and Number:
Japanese Patent JP6134628
Kind Code:
B2
Abstract:
This compressor is provided with: a plurality of vanes (10) at a vane stage (91) provided to a rotor casing demarcating the primary duct (4) for air (A) in the gap with respect to a rotor; an air bleed chamber casing that demarcates an air bleed chamber interconnecting with the primary duct (4) via a slot (13) formed in the rotor casing downstream of the vanes (10); and an air bleed tubing (15) connected to the air bleed chamber casing. Of the plurality of vanes (10), when a plurality of vanes (10) positioned at a region including the position in the peripheral direction (Dc) corresponding to the air bleed tubing (15) are a first vane group (101) and a plurality of vanes (10) other than the first vane group (101) are a second vane group (102), the spacing between the ends at the outside in the radial direction of the vanes (10) that are adjacent in the first vane group (101) is closer than the spacing between the ends at the outside in the radial direction of the vanes (10) that are adjacent in the second vane group (102).
