ROTARY MACHINE Russian patent published in 2017 - IPC F01C1/20 F04C18/20 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in steam and pneumatic drives and compressors. Rotary machine comprises housing 4 with high and low pressure branch pipes 6 and 5 and consistently rotating, at least, one rotor 1 with vanes 2 installed in it and opposite installed closers 3. Closers 3 are made in form of tightly adjacent to rotor cylinders with longitudinal groove 11 for passage of vanes 2. Vanes 2 together with housing 4 separate variable volume working chambers. Vanes 2 are bent towards closers 3 with provision of their dense movable contact with closers 3 along groove 11 boundary. Number of vanes 2 and rotor 1 speed are associated with speed and number of longitudinal grooves of closers 3 by definite relationship.

EFFECT: invention is aimed at increasing of compression ratio, reduced material consumption, increased efficiency or power of machine.
