METHOD OF PRODUCING MECHANICAL ENERGY Russian patent published in 1997 - IPC

FIELD: hydraulic power engineering. SUBSTANCE: device consists of several same cascades which are interconnected to form a united heat circuit. Each cascade consists of a hydraulic motor connected to a water reservoir. The hydraulic motor underlies the fluid surface level. The fluid flowing through the hydraulic motor enters evaporator wherein it is converted into gas. The gas pressure in the evaporator and the pressure of the fluid at the outlet of the hydraulic motor are less than the pressure of the fluid at the inlet of the hydraulic motor that is due to the action of gravity. The pressure difference does a work thus producing mechanical energy. EFFECT: . cl, dwg
