FIELD: compressor construction, in particular, multiple-staged compressors. SUBSTANCE: compressor has blades composed of parts 4,5,6 directed at different angles to axis of rotation of rotor. Guiding part 4 of blade is directed at an angle of 0-10 deg, compression part 5 at an angle of 15-60 deg and releasing part 6 at an angle of 50-85 deg to rotor axis. Cylindrical surface of rotor is divided into equal sections. Length of guiding part 4 of blades 3 is gradually increasing within each section to define air intake cavity. Compression part 5 of each blade has thickness gradually increasing toward releasing part 6. Releasing part 6 of each blade has constant thickness and its side surfaces define in conjunction with surfaces of adjacent blades slit channels. EFFECT: increased efficiency by creating increased pressure. 3 dwg
