FIELD: pump engineering.SUBSTANCE: invention relates to pump and compressor engineering industry and can be used for compression and delivery to consumers of pressurized gases and liquids. Rotary machine comprises working cylinder 2 accommodating main rotor 3, having at least one ledge 4, radius of which is equal to radius of cylinder 2, and auxiliary rotor 6 with dent 7 to accommodate ledge 4 of rotor 3. Both rotors 3 and 6 have a kinematic linkage, providing their synchronous rotation. One of kinematic gears providing synchronous rotation of rotors 3 and 6, is formed as a spur gear, and others have form of U-shaped cup which walls comprise teeth whose number is equal to number of teeth at cylindrical gear.EFFECT: invention is aimed at improving maintainability and service life, ease of manufacture and assembly of the machine.1 cl, 2 dwg |
