| Summary: | A compressor for compressing a gas comprises an impeller wheel mounted within a housing defining an inlet and an outlet. The inlet comprises a map-width enhanced structure with an annular flow passage defined between inner and outer tubular walls. The flow passage is in fluid communication with the impeller wheel by virtue of a slot in the inner wall. A flow-conditioning member is positioned in the annular flow passage and serves to remove swirl from the gas flow that recirculates through the passage. The flow-conditioning member comprises a body penetrated by a plurality of bores. The arrangement provides for a significant improvement in the surge margin of the compressor and is particularly suitable for use in a turbocharger. |
