Gas turbine engine air valve assembly

摘要

A gas turbine engine air valve assembly (200) has first and second valving elements (208,202). The second element (202) is rotatable about a first axis (502) relative to the first element (208). The rotation controls a flow of air through the first and second elements (208,202). An actuator (220) is coupled by a linkage (222) to the second element (202). A plurality of follower member assemblies each have an insertion portion extending through a corresponding first aperture (424) in the first valving element (208) and a corresponding second aperture (402) in the second element (202). The insertion portion is circumferentially fixed relative to one of the first and second valving elements (208,202) and circumferentially moveable relative to the other of the first and second valving elements (208,202).
