FLOW ENERGY CONVERTER Russian patent published in 2019 - IPC F03B3/08 F03B7/00 F03B13/00 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to liquid flow energy converter and can be used for heater radiator drive. Converter includes shaft 1, conical tubular spiral 4 with inlet and outlet channels 2, 3. Shaft 1 is pressed into bearing 15 rigidly secured to post 17. To shaft 1 cone-shaped base 14 is rigidly fixed, to which spiral 4 is rigidly fixed. Pipes 7, 8 are connected via articulation joints 5, 6 with shaft 1. On branch pipe 8 percussion unit 12 is installed. Pipes 7, 8 are connected to suction and pressure pipelines 9, 10 of centrifugal pump 11 to form closed hydraulic circuit. Unit 12 is connected with electric drive 13. Converter contains second bearing 16, second rack 16, the impeller with blades 24, starting motor 19 with shaft 23, driving and driven pulleys 22 and 20, drive belt 21. Bearing 16 is installed on shaft 1 and fixed on second post 18. Impeller with blades 24 and pulley 20 are installed on shaft 1, pulley 22 – on shaft 23 fixed on posts 17, 18. Pulleys 22 and 20 are interconnected by belt 21. Base 14 is made integral with spiral 4.

EFFECT: invention allows the most complete use of energy of working medium, reduces losses during rotation of spiral, increases frequency of rotation of movable part of converter.
