IRRIGATION SYSTEM Russian patent published in 1998 - IPC

FIELD: agriculture, in particular, supplying of water in accordance with water requirements. SUBSTANCE: irrigation system has vessel, water source connected with water supply pipeline via vacuum valve and branch pipes with vessel. On and off float valve is mounted in upper part of each vessel and water discharge branch pipe is connected to each lower part of each vessel. Water is consumed from each vessel as it is absorbed by soil without vacuum intercept due to operation of float valve, which cuts off water supply into vessel as it is filled with water and prevents vacuum intercept during emptying of vessel by being put onto opening seat. EFFECT: increased efficiency and simplified construction. 3 dwg
