<p>The compressor (10) has a cylindrical case (16) formed with annular ferrules (20, 22) that hold annular rows of straightening vanes (14). The ferrules have cylindrical edges (26, 28) to carry annular flanges (30, 30'), arranged at equal distance from the ferrules, for fixing the ferrules between the edges. The edges form an annular groove around movable vanes (12) placed between the ferrules for assembling an abradable element, where the internal diameter of the groove is higher than the external diameter of a theoretical vein in a part of the case.</p> |
