Title:
コンプレッサ、これを備えた過給機、ならびにコンプレッサのスロート通路幅調整方法
Document Type and Number:
Japanese Patent JP6621982
Kind Code:
B2
Abstract:
The purpose of the present invention is to be able to flexibly handle a variety of specifications while reducing the cost of manufacturing a centrifugal compressor. A compressor (8) comprises: a throat passage (41) that is formed on an outer peripheral side in a radial direction of a compressor impeller (18); a plurality of guide vanes (43) that each have one axial direction end fixed to a passage side surface (92a) of the throat passage (41) and form a diffuser (23); and a spacer plate (45) that has formed therein a plurality of slit holes (47) into which the guide vanes (43) are inserted and that is stacked on the passage side surface (92a). The axial direction height of the guide vanes (43) can be changed by exchanging the spacer plate (45) for a spacer plate of a different thickness. Due to this configuration, a variety of specifications can be flexibly handled by changing the width (W) of the throat passage (41) by appropriately selecting the plate thickness (T) of the spacer plate (45).
