FIELD: construction.
SUBSTANCE: air-hydraulic water lift contains lower tank with inlet and outlet tubes, overhead tank, gate switch and partition of pools. Additionally water lift contains upper tank with air duct and water conduit with return valve communicating with overhead tank. Lower tank is equipped with floater and gates with rods. Gate switch is made in the form of cylindrical sealed body. Flexible and moving spherical element is located inside cylindrical body. Support in the upper part has gate fixing component. Fixing component communicates with rods of lower tank having thrusts to contact levers of gate switch.
EFFECT: reduction in lost of energy during friction and simplification of liquid lifting.
