ABSTRACT:
A centrifugal compressor has a diffuser operative to convert the kinetic energy of fluid discharged from an impeller into pressure and having a shroud, a main shroud, and stationary vanes disposed in the diffuser. The distance between the shroud and the main shroud is smaller at an inlet side of the diffuser than at an outlet side thereof. The stationary vanes are integral with the one of the shroud and the main shroud that is perpendicular to the axis of rotation of the impeller so that an end surface of each of the stationary vanes forms a free end.
