摘要

The turbomachine has a stator including a stage of diffuser vanes with variable orientation, arranged in a case. Each blade has a pivot (20) extending along a pivot axis and projecting over the case. Each blade comprises a conical housing (26) extending transversally to the axis. A tie rod (16) connecting the blades to an actuating rim has a conical portion (28) engaging in the conical housing and fixed to the pivot. An independent claim is also included for a system for positioning a blade with variable orientation.
