Abstract: A drip irrigation emitter (10) includes first and second members (12, 14) and a deformable membrane (32). The membrane is located between the members and pins (22) that are located on the first member are received within holes (21) formed in the second member. End portions of the pins that project out of the holes are deformed and by that press the first and second members together and compress the membrane.

Abstract: An irrigation pipe coupler can engage an open end of an irrigation pipe with its forward end. The coupler has a nipple and an outer collar. The nipple has an outwardly projecting barb and the collar surrounds the nipple and has an inwardly projecting bulge. The collar is slidably moved along the nipple between forward and rear terminal positions while being kept spaced radially outwardly from the nipple via a peripheral gap that is re-defined for each new position of the collar along the nipple. At each such new position the gap has a narrow region measured in the radial direction where the collar is closest to the nipple and the narrow region gets smaller at least during at least part of the forward movement of the collar along the nipple.

Abstract: A pulsating irrigation device is provided that transforms a fluid flow entering the device to an intermittent pulsating fluid flow that is ejected from the device. The device has a chamber and at least one compressible member in pressure contact with the chamber. The compressible member compresses to assist the formation of the pulses ejected from the device and the fluid within the chamber is substantially sealed from contact with the interior of the compressible member.
