The invention relates to a device for adjusting the pitch of at least one annular row of stator vanes (5) for a turbomachine module, the device comprising means for individual adjustment of the pitch of said vanes (5), comprising a first control ring (24) mounted such that it can be rotated about an axis (X-X) of the turbomachine, connecting rods (25-30) for connecting said first control ring (38) to the vanes (5), and a second control ring (38) mounted such that it can be rotated about said axis (X-X), each vane (5) of said at least one row being connected to both said first (24) and second (38) control rings by an assembly of at least two rods (25). The invention also relates to a module and a turbomachine comprising said device, and to a method for adjusting the pitch of the vanes of the annular row. |
