METHOD TO LIFT WATER AND DEVICE FOR ITS REALISATION Russian patent published in 2012 - IPC F04F5/54 

FIELD: machine building.

SUBSTANCE: method to lift liquid includes ejection of atmospheric air with a water jet leaking through a nozzle into a mixing chamber under action of hydrostatic pressure existing in a water reservoir, and separation of a water and air flow exiting a lifting pipe into liquid and gas phases with liquid phase supply into an accumulating reservoir 4. At the same time a water receiving nozzle with a water-lifting pipe 1 is given reciprocal motion. Downward movement is carried out under action of the nozzle and the lifting pipe 1 gravity, and upward movement - with the help of a lever 3 loaded with lifted water and/or muscular efforts of a human being. Loading of the lever 3 with raised water may be carried out by preliminary drainage of the raised water into an intermediate water collecting reservoir 4 until its required volume is accumulated, and then its displacement with the help of a siphon pipeline 8 into the second intermediate reservoir 5, suspended at the lever end 3.

EFFECT: method improvement, reduction of costs.
