    • An actuation system for a plurality of variable stator vanes pivotally mounted in a casing of a compressor. The system includes a plurality of levers each having a proximal end and an opposite distal end. Each of the proximal ends are fixedly coupled to a corresponding stator vane of the plurality of variable stator vanes for pivoting the corresponding stator vane about a stator vane axis. The system also includes an actuation ring coaxially surrounding the casing adjacent the plurality of levers. The actuation ring is coupled to the distal ends of each of the plurality of levers for pivoting the levers as the actuation ring is rotated about a compressor rotation axis. The actuation ring includes a pin extending outward from a radially outward surface of the actuation ring. The system also includes a template comprising a slot for receiving at least a portion of the actuation ring pin. The slot includes a shape configured to guide rotation of the actuation ring about the compressor rotation axis when the template is moved relative to the actuation ring.
    • 用于可枢转地安装在压缩机壳体中的多个可变定子叶片的致动系统。 该系统包括多个杠杆,每个杠杆具有近端和相对的远端。 每个近端固定地联接到多个可变定子叶片中的对应的定子叶片,用于围绕定子叶片轴线枢转相应的定子叶片。 该系统还包括一个致动环,其致动环同轴地围绕与多个杠杆相邻的壳体。 致动环联接到多个杠杆中的每一个的远端,用于当致动环围绕压缩机旋转轴线旋转时枢转杠杆。 致动环包括从致动环的径向向外的表面向外延伸的销。 该系统还包括模板,其包括用于接收致动环销的至少一部分的槽。 狭槽包括形状,其被配置为当模板相对于致动环移动时引导致动环围绕压缩机旋转轴线的旋转。
