Abstract: A drip irrigation device for distributing a portion of the water flowing in an irrigation pipe to a plant, the device comprising: a housing formed from a relatively soft plastic; and a connector for coupling the housing to the irrigation pipe comprising a bayonet for puncturing the irrigation pipe formed from a relatively hard material over-molded onto a feature of the housing made from the soft plastic.

Abstract: A pulsating device has a chamber for receiving liquid entering the device and gas that occupies an initial volume in the chamber. The liquid entering the chamber compresses the gas and decreases the volume occupied by the gas, thereby increasing the pressure in the chamber. A valve is provided to open above a first threshold pressure to begin a pulse of liquid. The valve closes below a second threshold pressure to end the pulse. The pulsating device has an outlet gate that permits liquid in the chamber to exit the chamber when the pressure in the chamber is greater than the pressure outside the chamber.

Abstract: An emitter comprising: a plurality of inlet apertures through which liquid enters the emitter; a manifold flow channel into which liquid that passes through the apertures flow; an elastic diaphragm that seats on the manifold flow channel; an outlet aperture through which liquid that enters the emitter exits the emitter; wherein liquid that enters the inlet apertures displaces only a portion of the diaphragm from the manifold channel so that the liquid can leave the manifold channel and flow through the emitter to reach the outlet aperture.
Abstract translation: 发射器包括：多个入口孔，液体通过所述入口孔进入发射器; 歧管流通道，通过孔流动的液体流入其中; 位于歧管流道上的弹性膜片; 出口孔，通过该出口孔流入发射器的液体离开发射器; 其中进入入口孔的液体仅使歧管通道的一部分位移，使得液体可以离开歧管通道并流过发射器以到达出口孔。

Abstract: A fluid flow regulator (20) comprising: a fluid inlet port (34) and a fluid outlet port (54); at least one open-faced flow control channel (60) defined by a planar bottom (62) and two sidewalls (64) that communicates with the outlet port (54) at a junction (66) and has a cross-section that decreases with distance from the junction; an elastic diaphragm (40); a support shelf (58) on which the diaphragm (40) seats and which supports the diaphragm (40) along a planar contour parallel to the bottom of each of the at least one channel (60); wherein to regulate fluid flow, with increasing inlet fluid pressure the diaphragm (40) covers portions of the open face that are farther from the junction (66) in a region where the cross-section decreases with distance from the junction (66).
