ROTOR SCREW MACHINE Russian patent published in 2018 - IPC F01C3/02 F04C18/52 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in steam and pneumatic drives, compressors, internal and external combustion engines. Rotor screw machine comprises an axisymmetric rotor 1 with multiple-thread screw channels 3, at least one, which are cut on the rotor 1 around the ring, from different ends are connected to the high and low pressure branch pipes 5 and 6 and tightly blocked by the housing 7 and the movable separating flaps 2. Flaps 2 are fixed on the closed flexible chains 9 links, at least one, moving crosswise to the channels 3 in the located in the housing 7 grooves 11. Channels 3 are cut on the rotor 1 any or all of the outer, inner, and end surfaces, and are individual or combined expansion and compression stages.

EFFECT: invention is aimed at increase in the compression degree, increase in the productivity.
