TRICKLE Russian patent published in 2009 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: invention relates to watering of crops by trickling method. A trickle comprises a case with a bottom and riffles, a water discharge opening, a smooth flat valve made from elastic material, a holder, a cover with an input opening and a coupling connecting pipe. The holder of the smooth flat valve is made solid with the cover as one unit. The lower holder surface facing the smooth flat valve is fitted by splitting-swirling units for water flow which are of curvilinear shape and serve as an additional pressure suppressing unit. The riffles-channels on the case bottom are bending at a blunt angle near the end of the water discharge opening and going further on the inner walls of the water discharge opening; the above facilitates stable performance and self-cleaning of the trickle. The connecting pipe tip is equipped by a stop in the form of one turn of thread.

EFFECT: simplifying the design and manufacturing process as well as in improving reliability of the operation.
