ABSTRACT:
A variable stator vane actuating lever (50) for use in a compressor (20) of a gas turbine engine (10). The lever (50) comprises a first end (52) for pivotal connection to a stator vane actuator ring (36) and a second end (54) for abutting a stator vane spindle (32). The stator vane spindle (32) has a diameter and flat positions (56,58,60,62). The second end (54) of the lever (50) has resilient members (64,66) for abutting the flat portions (56,58,60,62) of the stator vane spindle (32) at diametrically opposite locations. The resilient members (64,66) are integral with the second end (54) of the stator vane spindle (32) and are curved so that they are substantially tubular to provide even load distribution and improved location of the lever (50) on the stator vane spindle (32).
