Abstract: What is disclosed is an improved sprinkler utilizing a nutation mechanism. The sprinkler utilizes a race having an upper limit and lower limit. The tire is connected to the distributor. Water sprays on the distributor causing the nutation of the device in which the tire moves between the upper race and lower race limits. The sprinkler includes a separate starting mechanism on which a starting bump is positioned on a distributor support.

Abstract: A sprinkler head with a nutating water distribution cage attached to a sprinkler body. Water from the sprinkler head impacts a strike plate of the cage to initiate nutation of the cage. Spiral grooves on the strike plate contribute to the nutation of the cage, and an upturned edge on the periphery of the strike plate contributes to the spread and uniform distribution of water from the sprinkler head.

Abstract: What is disclosed is a sprinkler apparatus and system for distributing a liquid preferably for use in an irrigation system. The sprinkler apparatus utilizes removable, replaceable, and interchangeable nozzles that are configured to vary the flow and/or location of a spray of water from the nozzle at a distributor. The distributor is configured to rotate to distribute the liquid flow from the distributor in a plurality of directions. The distributor utilizes a motor to control the flow of liquid from the distributor. Preferably a sprinkler is provided with multiple nozzles such that a user and/or consumer can select which nozzle flow is desired for implementation in a given situation.

Abstract: An improved nozzle assembly for use with a sprinkler body. The nozzle assembly has a nozzle body having a nozzle insert bore and defining a fluid flow path through the nozzle assembly. A nozzle insert is positioned in the nozzle body and retained within the nozzle assembly. The nozzle insert is rotatable between operating positions. In some embodiments, a spring biased detent and detent notches index the nozzle insert at one of a series of operating positions. The nozzle insert is rotatable between the series of operational positions including the IN (or insertion) position, the RUN position, the OFF position, the FLUSH position, and the LINE FLUSH position. In an alternate embodiments the nozzle insert has detents on a circumference of the nozzle insert. A magnet is positioned in or attached to the nozzle insert. A second magnet is positioned in or attached to the body of the nozzle assembly. The detents are configured to align with detent notches in a faceplate of the nozzle assembly body. When the detents are aligned with the detent notches, the attractive force between the two magnets retains the nozzle insert in one of the operating positions in the nozzle insert bore.

Abstract: What is disclosed is a pressure regulator having a mechanism to turn fluid flow through the pressure regulator on or off. The pressure regulator incorporates an actuator by which fluid flow to a pressure chamber that controls the linear movement of a flow tube is selectively actuated from one of a downstream supply and a pressurized fluid supply, such as an upstream supply. The actuator can be a manual, electromechanical, hydraulic or other form of actuator.

Abstract: What is disclosed is an improved irrigation valve that utilizes an upper diaphragm and a lower diaphragm. The valve has a housing having an intake and a discharge. The lower diaphragm serves to provide a seal between the intake and discharge when the valve is in an off position. In the on position the valve allows fluid flow into the intake and out the discharge. The valve utilizes an upper chamber that when pressurized causes the upper diaphragm to contact and exert pressure on the lower diaphragm, causing the lower diaphragm to close an orifice between the intake and the discharge of the valve housing. The upper diaphragm and the lower diaphragm define a chamber that is preferably vented to atmosphere.
