摘要： An apparatus for controlling air flow includes a grating having a plurality of air vents, a shutter assembly composed of a shutter fixed plate, having a plurality of first openings, attached to a lower surface of the grating, and a shutter moving plate, having a plurality of second openings corresponding to the first openings, movably disposed between the grating and the fixed plate. An opening-ratio controller moves the moving plate with respect to the fixed plate whereby an opening ratio defined by relative positions of the first openings and the second openings is controlled. The separation between the grating and the shutter fixed plate may be the thickness of the shutter moving plate. The opening-ratio controller may include an opening-ratio controlling screw having a pinion attached to the screw end.
