  • Patent number: 9744541
    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.

  • Patent number: 9414551
    Abstract: An irrigation pipe connector has a core that is adapted to connect to an irrigation element and a wing that is attachable to a wall of a pipe. The wing is provided with resiliency to allow the connector to deform in response to changing fluid pressures in the pipe. In addition, the wing may be provided with a thin segment in order to reduce potential damage during welding of the wing to the wall of the pipe.

  • Patent number: 9291276
    Abstract: An irrigation valve has a liquid passage, a sealing diaphragm and a control port that can receive control signals. The sealing diaphragm is held in the valve in a non clamped manner and is adapted to seal the passage. Upon receipt of a control signal the sealing diaphragm bends and opens a path for liquid around the sealing diaphragm that can exit the valve.

  • Patent number: 9052045
    Abstract: A fitting assembly that can attach to an open end of a flexible pipe has a nipple and a clamp. For attachment, the pipe is fitted with its open end over the nipple and the clamp fits over the pipe where the pipe fits over the nipple. The nipple has a seal and a barb arrangement that is located rear to the seal. The seal and barb arrangement contact an inner face of the pipe. The clamp has an axial extension that is sized to overlie the barb arrangement and the seal in order to press the pipe against the barb arrangement and the seal.

  • Patent number: 8998113
    Abstract: A drip irrigation emitter receives liquid flowing in an irrigation pipe at an inlet pressure and emits the liquid out of the emitter at an outlet pressure lower than the inlet pressure. The emitter has a flow path through which the liquid flows in the emitter, wherein below a threshold pressure of liquid in the pipe the emitter is adapted to emit a regulated flow of liquid out of the emitter, and above the threshold pressure of liquid in the pipe the emitter is adapted to emit a non-regulated flow of liquid out of the emitter.

  • Patent number: 8893987
    Abstract: A drip irrigation pipe includes a drip emitter and a flap that is formed in the pipe wall by first and second grooves. The first groove is longer than the second groove and the flap remains connected to the pipe wall at two bridges. A pivot region of the flap extends between the two bridges and the flap is adapted to twist about the pivot region as liquid exits the pipe at the flap.

  • Patent number: 8672240
    Abstract: An irrigation pipe with holes is provided. The pipe is, at least in the area of each hole, multilayered. At least top and bottom layers of the pipe are made of a water-repellant material, and an inner layer of the pipe is made of a porous material. The hole is defined by a cut surface of the pipe wall. The cut surface comprises a seal, which covers at least the inner layer. Each layer may be bonded to adjacent layers.

  • Patent number: 8646734
    Abstract: A sprinkler irrigation stand for use with an irrigation pipe has a base placed below the pipe for being stabilized by the pipe. The pipe freely rests upon the base so that it may be lifted freely off the base or may inflate freely upwards in the case the pipe is a collapsible pipe. A riser of the stand for supporting a sprinkler may be attached to the pipe and slide up in relation to the stand when attached to a collapsible pipe that is inflated.

  • Publication number: 20140001743
    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. A window formed in the collar allows an operator to see an irrigation hose inserted into the gap.

  • Patent number: 8511585
    Abstract: A drip irrigation emitter has first and second inlets through which liquid enters the emitter from an irrigation pipe, an outlet through which liquid exits the emitter, and a first flexible diaphragm portion seated on the second inlet and serving as a valve. Liquid at a pressure in the pipe that is below a predetermined level enters the emitter via the first inlet and travels along a first flow restricting path before exiting via the outlet and liquid at a pressure in the pipe that is above the predetermined level biases the first flexible diaphragm portion so that liquid can enter the emitter via the second inlet and travels along a second flow restricting path before exiting via the outlet.
