摘要： The invention relates to a mixed-type compressor where each compression stage comprises a main impeller (8) with a diameter increasing in the upstream-downstream direction at the input and at least one fixed rectifier (13, 14) at the output. This compressor is remarkable in that an additional movable impeller (10) is fitted between the main impeller and the fixed rectifier, said impeller (10) being integral in rotation with the main impeller and of the axial vane type with a higher camber at the top than at the bottom so as to reduce the radial gradient of the total flow pressure between the input and the output of said vanes. Such an additional impeller reduces the flow distortion at the output of the rotor and thus also reduces the losses in the fixed rectifiers while producing a maximum pressure ratio.
