Diffuser system and centrifugal compressor comprising the same

Abstract

The present application discloses a diffuser system and a centrifugal compressor comprising the same. The diffuser system comprises: a passage through which a compressed gas is flowable; and a wall defining the passage, the wall comprising a movable part which is driven to enter the passage so as to change a flow area of the passage, wherein the movable part comprises an elastomer configured to expand to guide the flow of the compressed gas when at least a portion of the movable part enters the passage, and to retract when the movable part withdraws from the passage. The diffuser system involved in the present application re-orients a flow route of the compressed gas in the passage.
