The device (10) has a synchronizing ring (14) connected to a diffuser (16), and including coaxial inner and outer rims (38, 40). Radial blades (42) are extended between the rims. The diffuser includes coaxial inner and outer revolution walls (32, 34) connected to each other by a radial partition (36). The outer rim is formed in a single piece with the outer revolution wall, and the inner rim is connected and fixed on the inner revolution wall by welding (44). The blades are integrated to the outer rim by an end and are spaced from the inner rim with a low radial clearance (46) at another end. |
