Abstract:
In the present invention, the pressure reducing flow path reduces the pressure of an irrigation liquid, and guides the irrigation liquid to the flow-rate decreasing part. The bypass flow path guides the irrigation liquid to the flow path opening/closing part in a state where the pressure of the irrigation liquid is maintained at a pressure higher than that of the irrigation liquid that has passed through the pressure reducing flow path. When the pressure of the irrigation liquid is lower than a first pressure, the irrigation liquid passes through the pressure reducing flow path and the bypass flow path to be guided to the discharge part. When the pressure of the irrigation liquid is a second pressure or higher, the irrigation liquid passes through the pressure reducing flow path to be guided to the discharge part.
