Actuating system for variable stator vanes

摘要

The mechanism consists of blades (3) connected by levers (9) to control rings (10) which are pivoted to cams (15), each turning about a first fixed axis (17). Each cam is linked to a control lever (21) which rotates about a second fixed axis (26) lying parallel to the first one by means of an arm (22). The arm is pivoted to the cam and control lever at points which are separate from the two fixed axes. The cams (15a, 15b, 15c) which are connected to other control rings (10) are linked to a synchronising bar (20) at points identical to that of the first cam (15).
