摘要:
This emitter (120) comprises, downstream of a first pressure reducing flow path, a discharge amount adjustment part and a discharge part.. The discharge amount adjustment part communicates with the discharge part via two flow paths: a first hole (173); and a communication flow path including a second hole (174) and a second pressure reducing flow path. An irrigation liquid is supplied directly to the discharge part from the discharge amount adjustment part through the first hole (173) when the external liquid pressure is low, and supplied to the discharge part from the discharge amount adjustment part through the second hole (174) and the second pressure reducing flow path when the external liquid pressure is high.
