ROTARY-VANE DRIVE Russian patent published in 2022 - IPC F01C1/08 F01C1/20 F02B53/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a rotary-vane drive, in which both gaseous working bodies and liquids with increased pressure can be used as a working fluid. The organization of the movement of the working fluid between the volumes of the drive from the intake of a fresh charge from the collector to the exhaust gases is carried out due to the pressure difference in the cavities of parts and assemblies with their interconnected rotational movement relative to each other by the common drive of the rotor 2, which performs the complex function of the spool: the gas distribution mechanism in accordance with the phases of the working cycle. Periodically repeating sequential thermodynamic processes occurring in the drive volumes provide heat supply to the working fluid and the conversion of the potential energy of gases with high pressure into mechanical operation when they expand in the channels.

EFFECT: invention is aimed at providing the possibility of reducing heat losses, reducing hydraulic losses and losses of the working fluid.
