FIELD: engines and pumps.
SUBSTANCE: pump housing 1 accommodates evaporation, operating and condensation chambers 5, 11, 19 faced on their inside by wick 2 and partially filled with readily boiling liquid. It comprises also partition 10 and condensate reservoir 14. Layers of porous material 6 line top face wall 3 of chamber 5. Chamber 5 houses perforated separation board 9 and pressure pipeline 7 with nozzle 8. Chamber 11 houses shaft 12 with feed pump 13 communicating with pipeline 7. Housing of pump 13 is arranged in reservoir 14 with its perforated walls staying in contact with wick 2. Turbine wheel 15 is fitted in housing 16 communicating, via steam nozzle 17, with chamber 5, and, via steam branch pipe 18, with chamber 19. Shaft 12 is furnished with propeller 20 on chamber inside, and, on chamber outside, it has draw-in hole 23 and pressure branch pipe 24.
EFFECT: higher efficiency and reliability.
