An axial flow compressor including one or more axially spaced stator sections ( 14 ) each having a circumferential array of guide vanes ( 15 ), and one or more rotor section (12, 16) each having a circumferential array of rotor blades ( 13, 17; A, B), and between successive rotor blades (A, B) there are formed flow paths and between the stator and rotor sections there are provided axial gaps ( 22, 23, 24 ) of a diverging configuration so as to form in each flow path a diffusion region (C) which extends from a narrowest cross section (a<SUB>2</SUB>) of the flow path located at a certain distance upstream of the leading edge of a second rotor blade (B) to a wider cross section (a<SUB>3</SUB>) located approximately at the leading edge of the second rotor blade (B), wherein each flow path has a transition region (D) of a substantially non-increasing cross sectional area extending from the wider cross section (a<SUB>3</SUB>) to the trailing edges of the rotor blades (A, B). |
