Abstract: An emitter (120) forms a flow path that runs to a discharge part (250) from an intake part (220) for receiving an irrigation liquid in a tube. The flow path includes a flow volume control part (240) which includes: an end surface (243) including a concave inclined surface that faces a film (300) for receiving the pressure of the liquid inside the tube; a hole (244) that opens at the center of the flow volume control part (240) and connects to the discharge part (250); and a groove (245) crossing the inclined surface and running to the hole (244). When the film (300) adheres to the inclined surface as a result of the pressure of the irrigation liquid inside the tube, the flow volume of the irrigation liquid inside the emitter (120) is controlled so as to be a volume that can pass through the groove (245).

Abstract: An emitter forms a flow path that runs to a discharge part from a water collecting part for receiving an irrigation liquid in a tube. The flow path includes a flow rate control part which includes: an end surface including a concave inclined surface that faces a film for receiving the pressure of the liquid inside the tube; a hole that opens at the center of the flow volume control part and connects to the discharge part; and a groove crossing the inclined surface and running to the hole. When the film adheres to the inclined surface as a result of the pressure of the irrigation liquid inside the tube, the flow volume of the irrigation liquid inside the emitter is controlled so as to be a volume that can pass through the groove.

Abstract: An emitter (120) adjusts the flow rate of a liquid for irrigation to be discharged from a discharge opening (112) of a tube (110) so that, according to pressure of the liquid for irrigation within the tube (110) received by a second membrane (153), the flow rate is made smaller as the pressure becomes greater in a prescribed range of pressure. The emitter (120) is constituted by mating a first member (130) having a bottom surface with a shape that follows along the inside wall surface of the tube (110) and a second member (150) that includes the second membrane (153) and is mated to the first member (130).

Abstract: This emitter is constituted 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. When the pressure of an irrigation liquid flowing through a tube is less than a first pressure, the irrigation liquid passes through the pressure-reducing flow path and the bypass flow path and is guided to the discharge part. When the pressure of the irrigation liquid flowing through the tube is equal to or greater than the first pressure, the second flow path is closed by the flow path opening/closing part, and the irrigation liquid taken in from the water intake part passes through the pressure-reducing flow path and is guided to the discharge part.

Abstract: An emitter (120) includes a flow path from a water intake path (221), which is for taking in irrigation liquid within a tube, to a recessed part (251). This flow path includes a recessed surface part (242) closed, without contact, by a film (300). A channel (243) that forms a reduced pressure flow path included in the above flow path is formed on the surface of the recessed surface part (242). If the film (300) is pressed by the pressure of the irrigation liquid in the tube (110) and adheres to the recessed surface part (242), the flow rate of the irrigation liquid inside the emitter (120) is controlled to an amount that can pass through the channel (243).

Abstract: An emitter (120) has, in a water intake part thereof, a water intake amount regulating part for preventing low-pressure liquid from flowing in. The water intake amount regulating part has a valve body (214) and a securing part (215). When the pressure of the liquid meant to flow into the emitter (120) is less than a set value, the valve body (214) does not move with the securing part (215), preventing the liquid from flowing into the emitter (120). When the pressure of the liquid is equal to or greater than the set value, the valve body (214) bends downstream to open the flow channel for the liquid.

Abstract: 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.
