Abstract RU 2229218 C1

FIELD: agriculture, in particular, irrigation equipment. SUBSTANCE: dripper has detachable case with inlet and outlet branch pipes, float equipped with locking members and mounted inside case, and tubular moistener made integral with case. Case defines in conjunction with cover cylindrical cavity for receiving of float with guides and conical locking members, with angle of taper being at least 90 deg. Gap between guides and case is 0.5 mm. Inlet branch pipe is made conical with diameter increasing toward float chamber. Tubular moistener has sharpened portion and rigidity ribs. Conical openings with angle of tapering of 60 deg are formed between rigidity ribs. Openings are uniformly distributed over entire side surface of moistener. EFFECT: enhanced reliability in operation and improved irrigation quality. 4 cl, 3 dwg
