The present invention relates to a variable throat device (100) for an air compressor, which is disposed in an air suction pipe (14) of an air compressor, and may secure reliable flow control by changing a cross-sectional area of the pipe (14) through application of force to the pipe (14), significantly reduce a possibility of unsteady flow by suppressing generation of a vortex in an air stream, secure a desired flow rate without pressure loss in the air stream, and reduce fatigue load applied to a compressor impeller through stabilization of suction flow in order to achieve significant reduction of vibration of the impeller. |
