Constant flow width through the last stage diffuser of a centrifugal compressor is maintained against widening by the forces of differential pressure via a diffuser defined between oppositely positioned radial faces of a diaphragm and an annular diffuser plate secured spaced from the diaphragm at the desired width. Although slight movement occurs in the compressor components, the width of the diffuser flow passageway is not affected since its width is fixed and the diffuser plate is free to move because of the pressure balance provided by the annular cavity and vent holes extending through the plate. |
