PURPOSE: An inlet guide vane assembly is provided to precisely and effectively control the flow rate of fluid passing an intake duct by opening the intake duct as occasion demands. CONSTITUTION: An inlet guide vane assembly comprises a vane (110), a control arm (120), a control ring (130), and a track roller (140). The vane is rotationally installed in the inner surface of an intake duct (D) to open and close an intake hole (H) formed in the intake duct. In order to control the angle of the vane, the control arm is connected to one end of the vane to rotate the vane. The control ring is rotationally installed in the intake duct. The track roller connects the control ring and the control arm. |
