WATER OUTLET FOR DROP IRRIGATION Russian patent published in 2006 - IPC A01G25/02 

FIELD: agricultural engineering, in particular, drop irrigation of farm crops, preferably in gardens and vineyards.

SUBSTANCE: water outlet has hydraulic accumulator divided by elastic diaphragm into cavities which communicate through differential valves with water outlet pipes. Water outlet pipes have locking members formed as nipple tips with elastic pipes. Water outlet is equipped with additional elastic diaphragm joined to main diaphragm through casing equipped with inlet opening connected with drop irrigation system pipeline. Diaphragms define in conjunction with casing within hydraulic accumulator high-pressure and average-pressure cavities. Both diaphragms have by-pass openings. Each of differential valves is defined by spring-loaded spherical member joined with diaphragm and seat. Seat is hydraulically communicated through nipple tip with elastic pipe. Each of seats has radial ribs for moving of spherical member.

EFFECT: increased efficiency in feeding of irrigation norm.
