FIELD: irrigated agriculture, in particular, equipment used for watering of perennial plants. ^ SUBSTANCE: dropper has casing and cover with inlet and outlet branch pipes, respectively, throttle and elastic balancing member with openings. Throttle is made in the form of hollow biconcave lens and positioned in casing cavity above elastic balancing member. Spherical segment-shaped slot is formed in cover body below inlet branch pipe. Radius of spherical part of said slot is equal to radius of throttle lens spherical part. Similar slot is formed in bottom part of casing above inlet branch pipe. Radius of said slot is greater than radius of spherical part of throttle biconcave lens part by value equal to thickness of balancing member. Channels are formed on casing bottom part surface and on slot surface to define spiral branches. Holes are made on peripheral part of elastic balancing member. ^ EFFECT: simplified construction and improved watering quality. ^ 2 cl, 6 dwg |
