Abstract: A sprinkler head having a spool assembly positioned within the lower sprinkler body of the sprinkler head. The spool assembly has a spool body having a distribution disc at an upper end of the spool body. The sprinkler head is configured with a nozzle that sprays fluid onto the distribution disk, causing the spool assembly to nutate within the lower sprinkler body when sprinkler head is running. The spool assembly is configured with two friction bands that are each configured to radially roll in or on a respective race within the lower sprinkler body. The friction bands can be integrally formed with the spool assembly or removably positioned on the spool assembly.

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.

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: What is disclosed is a self governing speed control device for controlling the rotation speed of a sprinkler turbine. The device has a housing that houses a viscous fluid. An axle extends into the housing and is configured to rotate in the housing. The axle is fixedly attached to a primary drum that rotates with the axle. One or more hinge pins extends from the primary drum. A brake shoe is positioned on the hinge pin. The hinge pin passes into a slot in an actuation drum configured to rotate on the axle. The brake shoe is configured to expand and contract based on the speed of rotation of the axle in relation to the speed of rotation of the actuation drum.

Abstract: What is disclosed is a sprinkler head having a nozzle configured for spraying a fluid, such as irrigation water, at a distribution disk. The distribution disk is configured to rotate on an upper axle. The upper axle is housed within an upper axle housing. The upper axle housing is configured to rotate about a lower axle. The dual axle provides for two different rotation axles of the distribution disk in operation. Preferably a speed control device can be positioned to control the speed of rotation of one axle or both axles.

Abstract: An improved gas vent having a body defining a float chamber. A float is positioned within the float chamber. The float chamber defines a passageway for gas to flow from an first port to an outflow port. A float is positioned within the float chamber. The float is configured to move toward a closed position as the fluid level within the float chamber increases. As the fluid level increases the float raises and seals against an interior of the gas vent, preventing further fluid flow through the vent. A shield is positioned between the float and the first port. The shield is configured to deflect gas flow around the shield and float to prevent the float from raising prematurely in response to high velocity gas flow on the float.

Abstract: An improved nozzle assembly for use with a sprinkler body. The nozzle assembly has a nozzle body having a recess and defining a fluid flow path through the nozzle assembly. A nozzle insert is positioned in the nozzle body and retained by a keeper tab that is positioned through an opening in a rear wall of the recess. The nozzle insert is rotatable between a series of operational positions including the IN (or insertion) position, the RUN position, the OFF position, the FLUSH position, and the LINE FLUSH position. A biasing plate is positioned on the face of the nozzle body and is configured to detent the turning knob of the nozzle insert in the RUN position. Further provided is a nozzle insert carrier configured to retain additional, not-in-use nozzle inserts with the nozzle assembly.

Abstract: A sprinkler head having a nutating fluid distribution cage. The sprinkler head has a first sprinkler body and a second sprinkler body. The first sprinkler body has an upper plate and a lower plate. A distribution cage is configured to hang from the lower plate when fluid is not being sprayed onto the cage. An upper cage plate of the distribution cage is configured to nutate between the upper plate and the lower plate when fluid is sprayed on the cage. The second sprinkler body is positioned below the cage and is connected to the first sprinkler body by one or more arms. The cage has a magnet coupled with a magnet of the second sprinkler body. The magnetic coupling allows the cage to hang at an angle from the lower sprinkler body plate when fluid is not sprayed onto the cage and/or to provide for a speed dampener of the rate of nutation of the cage.

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.
