Patent attributes
This emitter is configured from an emitter body, a film, and a cover. The emitter has a water intake part, a discharge part, a first flow path, a second flow path, a flow reduction part, a flow path opening/closing part, a pressure-reducing flow path, and a bypass flow path. If the pressure of an irrigation liquid flowing through a tube is less than a first pressure, the opening of a first water intake through hole of the cover is sealed with the film. If the pressure of the irrigation liquid flowing through the tube is equal to or greater than the first pressure, the film is deformed so that the irrigation liquid is taken into the emitter body through the first water intake through hole, the space between the film and the cover, and a second water intake through hole.
