Compressor housing for fluid-flow machine, has spiral shaped flow channel, where its cross section increases continuously to discharge part of compressor housing

摘要

The compressor housing (1) has a spiral shaped flow channel (7), where its cross section increases continuously to a discharge part (2) of the compressor housing. The rigidity of the compressor stator along the cross section of the flow channel has almost same values. Reinforcement ribs (3,4) are arranged in an angle area of compressor housing.
