FIELD: engines and pumps.
SUBSTANCE: invention relates to transport of fluids and gases, particularly to positive displacement rotor machines and can be used in production of pumps, compressors, hydraulic motors, air-operated engines and gas-expansion machines. Proposed machine comprises housing 1 and rotor 2 fitted off-center therein and furnished with cylindrical grooves accommodating rotary cylindrical bases 16 with shaped blades 17 representing two-part bent plate. First part 18 of blade 17 is jointed radially to the base, while second part 19 is made arc-like. Bases 16 have central bores, radial cutouts and round-rod torsions passed through aforesaid central bores. One end of aforesaid torsions is bent for 90° and foxed in grooves on side surface of rotor 2. Torsion other end is fitted in cutout of the base opposite end. Sectored cutouts 25 are made in rotor 2 nearby grooves 15.
EFFECT: simpler design, higher reliability and reduced power consumption.
