Abstract:
Provided are a centrifugal compressor gas-supplementing structure and a compressor using the foregoing gas-supplementing structure. The centrifugal compressor gas-supplementing structure includes a annular gas-supplementing passage ( 6 ) for introducing supplemented gas into a gas passage ( 5 ) of a compressor, and an airflow-guiding assembly is provided in the annular gas-supplementing passage ( 6 ). The gas-guiding assembly is used for adjusting a direction of the supplemented gas flowing into the gas passage ( 5 ), so that an angle between a direction of the supplemented gas flowing into the gas passage ( 5 ) and a direction of an airflow in the gas passage ( 5 ) falls within a preset range, and a turbulence loss generated when the two passages of gas merge is avoided to the greatest extent, thereby improving cycle efficiency.

Claim (Index 13):
The centrifugal compressor gas-supplementing structure as claimed in  claim 4 , wherein a thickness of the guide vanes ( 7 ) is the same as a thickness of the return vanes ( 41 ).
