Abstract (en)
[origin: EP1843008A1] The vane has a plate (13) perpendicular to direction formed by a blade (12) and a pivot (14). A surface of the plate opposed to the blade includes two zones (20, 22), where one zone (20) is subjected to high friction with a wall of a bore housing due to the stress transversely applied on the blade. A cavity (22A) in the zone (22) is fabricated in the surface turned towards the housing, where the cavity is not subjected to compression stress resulting from application of force on the blade. The cavity extends on an arc i.e. circle, from sixty to one hundred and twenty degrees around the pivot.
