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 cam 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). The cam mechanism (210) configured to 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).
