FIELD: engines and pumps. ^ SUBSTANCE: invention relates to compressors and can be used in whatever field wherein compression or pumping over of media is required. Proposed compressor comprises working elements rigidly fixed on hollow truncated-cone rotor side surface and on metal shaft aligned with compressor rotational axis. Note that aforesaid working elements represent spiral metal bans with inclination angle varying from 60 to 25 to compressor shaft, and varying pitch and height decreasing towards compressor outlet. Compressor working elements are rigidly fixed inside rotor and on metal rod running in compressor rotational axis. ^ EFFECT: simpler design, ease of manufacture and higher reliability. ^ 3 dwg |
