PURPOSE: A dropper is provided, to supply quantitative and constant amount of water for farm products irrespective of the slope of water pipe and the water pressure. CONSTITUTION: The dropper (1) comprises a body (2) which has a water inducing path (4) whose lower part is closed and whose upper part is opened; an arc member (3) which is formed in one body with the body (2) by extrusion molding, and is closely adhered to the inner wall of a water supply pipe (5); a hole (6) which is formed in the lower part of the water inducing path (4) to penetrate the wall of an arc member (3); a water stay space (7) where the water ejected from the water inducing path (4) through the hole (6) stays; a water releasing ball (8) which penetrates and is formed through the wall of the water supply pipe (5) to connect the water stay space (7) and the exterior; and a silicone flux control valve (9) having an elastic piece (9a) which is inserted into the water inducing path (4) not to block the hole (6), and shrinks to decrease the cross-sectional area in water pressure increasing. |
