Abstract (en)
The turbine stator guide for a blade (22) with a platform (23) and a pivot (24) located inside the turbine housing (3) includes a bearing (23b1, 26b1) that is integral with the platform. The bearing is in the form of an annular rib (26b1) that fits into a matching groove (23b1), the rib projecting from a flange (26b) adjoining the cylindrical portion (26a) of a bush located between the pivot and housing and adjacent to the end of the pivot sleeve (25). The position of the blade is controlled by a lever on the end of its pivot.
