Abstract
A stator stage of a compressor of a turbomachine including an annular row of variable-pitch vanes is disclosed. Each vane includes an external cylindrical pivot defining the axis of rotation of the vane, and an internal cylindrical pivot mounted in a housing of an internal ring. The internal pivot of each vane extends along an axis substantially parallel to the axis of rotation of the vane and at a distance from this axis, and is mounted in the housing of the ring by a swiveling or a tilting system.
