ROTARY-VANE MACHINE Russian patent published in 2013 - IPC F01C1/352 F04C2/352 

FIELD: machine building.

SUBSTANCE: rotary-vane machine has fixed housing 1, in which there is more than one internal cylindrical bore 2, which form working chambers of the machine, with working medium supply and discharge openings interconnected with pressure and drain main lines respectively. Adjacent bores 2 of housing 1 are made eccentrically and/or coaxially to each other. In cylindrical rotor 5 there is more than one cavity 10 with longitudinal radial shaped slots. Each of cavities 10 of cylindrical rotor 5 is combined with its corresponding internal cylindrical bore 2 of fixed housing 1. Eye lugs of vanes are arranged inside cavities 10 of rotor 5 and installed on axes 11 coaxial to axes of each of internal cylindrical bores 2 of fixed housing 1. Axes 11 are combined and made in their turn in the form of a single bell crank, the axes of which are located in relation to adjacent parts of the bell crank coaxially to axes of each of internal cylindrical bores 2 of fixed housing 1.

EFFECT: improving reliability, reducing friction and total mechanical losses and pneumohydraulic losses of a rotary machine and increasing its efficiency.
