Abstract (en)

An adjustment linkage (200a) for a guide vane (8) of a compressor (14) for a gas turbine engine (10). The adjustment linkage (200a) comprises a push rod (150). A first end (206) of the push rod (150) is configured to be coupled to an adjustment ring (140) for actuation of a variable guide vane (8a). A second end (208) of the push rod (150) is configured to be coupled to an output (152) of an adjustment drive (154) via a displacement mechanism (210) configured to modify the directional output (152) of the adjustment drive (154). The push rod has a longitudinal axis (212) which extends between its first end (206) and second end (208). There is also provided a push rod lever (220) pivotably coupled to the push rod (150) between the first end (206) and second end (208) of the push rod (150). The push rod lever (220) is configured to pivotably mount to an anchor point (221) on the compressor (14). Hence the push rod (150) is pivotable about the coupling with the push rod lever (220), and the push rod lever (220) is pivotable about its anchor point coupling to thereby allow the push rod (150) to move in a direction along its longitudinal axis (212) and restrict the push rod (150) from moving in a direction at an angle to its longitudinal axis (212).
