WATER LIFTING DEVICE Russian patent published in 2008 - IPC F04F1/18 F04F5/24 

FIELD: engines and pumps.

SUBSTANCE: water lifting device incorporates a lifting, intake in and air feed pipes, a mixing chamber with inclined nozzle holes (NH) and an umbrella-like head in the form of truncated cone (TC), its larger base directed downward and smaller base attached to the intake branch pipe end face. The TC inner surface has vertical trapezoidal plates arranged tangentially to the intake branch pipe cylinder part towards the annular inclination of the mixing chamber NH axes. The NH axes are generators of one-space hyperboloid of revolution. The mixing chamber inner bucket perimeter is furnished with an annular truncated cone bore with larger TC base upward. The TC generators are perpendicular to tangential planes at the points the latter cross the surface of the one-space hyperboloid of revolution. Conoidal nozzles with inlet diameters not over the width of the TC bore and outlet diameters equal to the TC diameters are arranged equally spaced along the circumference in recesses furnished along the medium axial. The conoidal nozzle axes are aligned with the respective TC axes.

EFFECT: higher efficiency and expanded performances of the unit.
