ROTOR DEVICE (VERSIONS) Russian patent published in 2009 - IPC F01C1/22 

FIELD: engines and pumps.

SUBSTANCE: invention is related to rotor devices. Rotor device comprises body that creates annular closed chamber with internal wall, double-cam symmetrical rotor, tops of which are located on its central longitudinal axis, inlet and outlet channels, the first and second guide facilities. Rotor is installed with the possibility of such rotation with eccentricity inside chamber, at which tops continuously contact internal wall of chamber, and as a result cavities are created between every cam and internal wall of chamber with serially increasing and decreasing volume. Rotor is installed on single shaft, which passes through opposite ends of chamber. Shaft centre is displaced to central axis of chamber. On shaft the first guide facility is installed, which represents unit intended for realisation of reciprocal motion relative to groove arranged in rotor, as a result, unit and shaft provide for rotation with rotor eccentricity. The second guide facility interacts with the first one and is intended for rotor direction, and during operation it provides for permanent tight contact with internal wall, as a result rotor centre is displaced in chamber along circular trajectory. Centre of the second guide facility is displaced relative to central axis of chamber.

EFFECT: provides for high thermodynamic efficiency and economic efficiency of production, simplicity of design, tightness and wear resistance.
