Abstract:
A variable-pitch control device for a turbomachine compressor is disclosed. The device includes a rod, a fastening device for fastening a first end of the rod to a pivot of a vane to be controlled, and a connection device between a second end of the rod and a control ring. The rod is substantially cylindrical, its first end being engaged in a bore in the pivot of the vane. The device further includes a clamping device for clamping the first end of the rod in the bore in the pivot in order to fasten it to the pivot.
