Vaned diffuser plays an important role in centrifugal compressor as it can improve the performance of compressor and broaden the operating range.

离心压缩机中，叶片扩压器对提高压缩机整机性能、拓宽有效运行范围发挥着举足轻重的作用。

Centrifugal FLOW compressor, a type of compressor in which air is taken into the center of the impeller and is slung outward centrifugally into a diffuser where it is slowed and pressure is increased.

离心式压气机，压气机的一种。当进气到达叶轮中心时，被叶轮离心抛出进人扩散器。在扩散器中气体流速减慢，压力增加。
