摘要:
The invention relates to a turbomachine fluid guiding stator device, comprising:
- a blade assembly (21), named stationary blade assembly (21), comprising:
∘ two rings (22) coaxial along an axis, named main axis (39),
∘ a plurality of blades (23) held between the rings (22) and mounted to pivot with respect to the two rings (22),
- a mechanism (24) for controlling the angular position of the blades (23) comprising:
∘ a plurality of levers (25) rotationally coupled to the blades (23),
∘ a ring (33) for controlling the angular position of the blades (23) and being able to be rotationally driven about the main axis (39) with respect to the two rings (22) of the stationary blade assembly (21) to allow the levers (25) to be rotationally guided,
characterised in that the control ring (33) is axially held on the main axis (39) exclusively by at least two levers (25).
