Patent ID: 8197190

Claim:
A lever for rotating about its pivot a turbomachine variable-pitch stator vane comprising: a first zone for attachment to a lever drive member; a second zone for attachment to said variable-pitch stator vane, said second zone including a radial upper face and a radial lower face; and a third zone of elongate shape between the first zone and the second zone, said third zone including a radial upper face and a radial lower face, said radial upper face of said second zone being radially higher than said radial upper face of said third zone and said radial lower face of said second zone being radially lower than said radial lower face of said third zone; wherein a vibration-damping laminate includes a first part applied to a surface portion of the second zone of the lever, a second part applied to a surface portion of the third zone of the lever, and an intermediate part which connects the first part to the second part, a portion of the intermediate part being free of contact of the lever, and wherein the laminate includes at least one layer of viscoelastic material in contact with said surface portion and a backing layer of rigid material.
