DROPPER Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, drop irrigation equipment.

SUBSTANCE: dropper has casing with inlet and outlet branch pipes. Float and locking member are located in casing. Hollow float is made in the form of biconvex lens. Slot is made in casing cavity of inlet branch pipe. Slot is formed as spherical segment with radius of sphere equal to or smaller than radius of sphere of float biconvex lens. Spherical segment shaped slot is formed in casing cavity of outlet branch pipe. Radius of sphere of said slot exceeds that of float biconvex lens. Locking member is defined by elastic membrane located in casing between float and outlet branch pipe. Inlet branch pipe and slot joined with membrane surface are equipped with radial channels. Dropper of such construction operates in any spatial position and does not require strict vertical positioning.

EFFECT: simplified construction and uniform and high-quality irrigation.
