Abstract (en)

[origin: EP1496208A1] The device has a fixing unit (22) externally surrounding a crankcase (10) of a turbomachine including multiple blades. Each blade has a pivot (14) that is guided in a cylindrical chute (16), and is linked by a connecting rod (40), to a control ring (42). The fixing unit guides an outer end of the pivot in rotation. The rod fixed on the pivot extending beyond the chute, supports and locates the ring remote from the crankcase.
