摘要： Provided is an emitter (120) comprising a flow path that leads from an intake path (221) for taking in irrigation liquid that is within a tube to a recessed section (252). The flow path comprises opening/closing sections (248) that are arranged with a gap (249) therebetween. The gap (249) communicates with a discharge section. When the opening/closing sections (248) are pushed by the pressure of the irrigation fluid within a recessed section (242), the tip sections of each of the opening/closing sections (248) are brought into contact and one part of the gap (249) is blocked. The flow rate of the irrigation fluid within the emitter (120) is controlled by the remaining amount of said irrigation fluid that is capable of passing through the gap (249).

摘要： An emitter is arranged inside a tube and has: an emitter main body that is constituted by a resin molded body that has at least a recessed part and a through hole; and a flexible film that is joined to at least one surface of the emitter main body and that forms a flow path by closing off the recessed part and an opening part of at least one part the through hole. The emitter has a discharge amount adjusting part that is for making adjustments in accordance with the water pressure inside the tube. When the pressure of an irrigation liquid that is inside the tube is at or above a set value, the film slackens, and the discharge amount adjusting part narrows the flow path of the liquid and reduces flow rate.

摘要： Dripper comprises Substrate integrally formed of a resin material and that includes a channel for an irrigating liquid. The channel comprises Inflow control part for controlling flowing in of the irrigating liquid and/or Flow rate control part for controlling the flow rate of the irrigating liquid that has flowed in. Inflow control part opens the channel in association with an increase in the pressure of the liquid to flow therein, and Flow rate control part closes the channel in association with an increase in the pressure of the liquid that has flowed in Dripper. Dripper is able to stabilize the control of inflow and discharge of the irrigating liquid, regardless of whether the pressure of the irrigating liquid increases or decreases, and also is able to achieve a reduction in manufacturing costs and improvement in manufacturing efficiency.

摘要： 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).

摘要： 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.

摘要： A dripper obtained by incorporating together a first member and second member, which are both resin moldings. The first member is on the side into which an irrigating solution flows, and the second member is on the side from which the irrigating solution is discharged. The dripper has an inflow part having a low-pressure stop filter function, and/or a diaphragm part for narrowing a flow path by elevating the hydraulic pressure of the irrigating solution. The dripper makes it possible to stabilize the amount of irrigating solution discharged, irrespective of the hydraulic pressure of the irrigating solution, and also makes it possible to reduce costs.

摘要： 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.

摘要： A drip irrigation emitter (1), which comprises a low pressure stop filter (5), a pressure reduction channel (8), and a diaphragm (10), is disposed on the inner wall surface of a flow pipe (3) through which the irrigation liquid flows. The low pressure stop filter (5) has a hydrophobic surface and prevents inflow of the irrigation liquid when the fluid pressure is lower than an established value. The pressure reduction channel (8) reduces the pressure of the irrigation liquid. The diaphragm (10) changes the degree of opening of the pressure reduction channel (8) according to the fluid pressure of the irrigation liquid. The drip irrigation emitter (1) can be manufactured at low cost as a result of being a one-piece molding. The drip irrigation device comprising the drip irrigation emitter (1) stably ejects the irrigation liquid even when the liquid pressure is low.

摘要： 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).
