Abstract
Official abstract text for this publication.
Dripper comprises Substrate integrally formed of a resin material and that includes a channel for an irrigating liquid. The channel comprises Inflow control part for controlling flowing in of the irrigating liquid and/or Flow rate control part for controlling the flow rate of the irrigating liquid that has flowed in. Inflow control part opens the channel in association with an increase in the pressure of the liquid to flow therein, and Flow rate control part closes the channel in association with an increase in the pressure of the liquid that has flowed in Dripper. Dripper is able to stabilize the control of inflow and discharge of the irrigating liquid, regardless of whether the pressure of the irrigating liquid increases or decreases, and also is able to achieve a reduction in manufacturing costs and improvement in manufacturing efficiency.
