Abstract
There is provided a compressor () and associated method for providing a flow of recirculated air to control surging in the compressor. The compressor includes a housing () with a compressor wheel () rotably mounted therein. The housing defines at least one injection port () configured to receive compressed air from the compressor wheel and recirculate the compressed air to an inlet passage () of the compressor. In particular, each injection port defines an outlet () proximate to the leading edges () of the blades () of the compressor wheel such that the compressed air is delivered to the leading edges and reduces the occurence of surging.
