DEVICE FOR WATER LIFTING Russian patent published in 2017 - IPC F04B47/00 

FIELD: transportation.

SUBSTANCE: device for water lifting can be used in hydrotransport and power systems, as well as in water supply. The device contains a housing, a water displacing body, disposed in the housing with a possibility of reciprocating movement along the housing axis due to the mechanical lifter from above. The water displacement to the consumer is achieved with a ratio of the housing and the submerged body diameters 1.2…1.02. The weight of the submerged body is concentrated in its lower part, and the upper part of the immersed body occupies the neutral position in the water. The weight of the submerged body has the value at which its excess pressure on the water exceeds the hydrostatic pressure in the housing.

EFFECT: device allows to lift water with the reduced energy costs due to the lightweight upper part of the submerged working fluid.
