Abstract
A compressor comprises an impeller wheel mounted within a housing defining an inlet and an outlet. The wheel has a plurality of vanes and is rotatable about an axis. The housing has an inner wall defining a surface located in close proximity to radially outer edges of the impeller vanes which sweep across said surface as the impeller wheel rotates about its axis. The inlet comprises inner and outer tubular walls extending away from the impeller wheel in an upstream direction and defining between them gas flow passage. A bleed passage between the gas flow passage and the impeller wheel is selectively opened and closed by movement of a sliding sleeve in a helical direction.
