FIELD: machine building.
SUBSTANCE: proposed machine comprises stator, rotor and working chamber formed there between. Working chamber is communicated with working medium feed and discharge channels. Working chamber cross-section width equals the difference between maximum and minimum radii of working chamber defined as the distance from machine axis to working chamber outermost point and the distance from the axis to innermost point. Working chamber houses blades and separator engaged with stator and rotor, respectively. Every blade comprises leading edge facing the rotor and arranged at β=5÷20° to meridian plane extending through leading edge centre. Blade cross-section mid line passed through leading edge centre is inclined to said meridian plane at α=5÷60°. Flat leading edge makes a sharp edge between edge plane and blade surface facing the rotor. Edge plane is parallel with the stator cross-section.
EFFECT: higher efficiency of operation.
