DEVICE FOR CONVERSION OF ENERGY OF WORKING MEDIUM TO ELECTRICAL ENERGY Russian patent published in 2015 - IPC H02K7/18 

FIELD: electricity.

SUBSTANCE: device for conversion of energy of a working medium to electrical energy includes a housing made in the form of a detachable cone ring, the inner cavity of which has a variable cross-section. Electrical power generator is installed on a shaft and provided with blades at a detachment point of the cone ring. Working elements are made in the form of elastic toroids, the inner walls of which are screw-like twisted relative to central axes of the working elements which are filled with elastic fillers and installed on an endless band in the ring cavity. With that, an outlet channel in the housing is formed with a connector of the ring with a maximum cross-section value at the outlet of the working element. Blades of the generator interact with the working elements. As fillers of the working elements, there used are cylindrical inserts with central holes along longitudinal axes, the diameters of which exceed diameters of screw-like twisted inner walls of the toroids. Surfaces of the inserts are coated with an antifriction lubricant. The inserts are two-layered, the external layer of which is made from elastically compressed material, and the internal one is stiff and tubular and forms a central non-deformed hole of each insert and has a curvature in a longitudinal cross-section, which corresponds to the curvature of the annular housing.

EFFECT: improving reliability.
