(EN) An emitter according to the present invention includes a water intake part, a discharge part, a first flow path, a second flow path, a flow-rate decreasing part, a flow path opening/closing part, a pressure reducing flow path, and a bypass flow path. The pressure reducing flow path is provided to the first flow path on the upstream side of the flow-rate decreasing part, reduces the pressure of an irrigation liquid, and guides the irrigation liquid to the flow-rate decreasing part. The bypass flow path is provided to the second flow path on the upstream side of the flow path opening/closing part, and 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 second flow path is closed by the flow path opening/closing part and the irrigation liquid passes through the pressure reducing flow path to be guided to the discharge part.
(ZH) 本发明的发射器包括取水部、排出部、第一流路、第二流路、流量减少部、流路开闭部、减压流路以及旁通流路。减压流路配置在流量减少部的上游侧的第一流路上，使灌溉用液体的压力减压并将灌溉用液体导入流量减少部。旁通流路配置在流路开闭部的上游侧的第二流路上，在将灌溉用液体的压力维持为比减压流路中流动的灌溉用液体的压力高的压力的状态下将灌溉用液体导入流路开闭部。在灌溉用液体的压力小于第一压力的情况下，灌溉用液体通过减压流路和旁通流路被导入排出部。在灌溉用液体的压力为第一压力以上的情况下，流路开闭部将第二流路闭塞，灌溉用液体通过减压流路被导入排出部。
