摘要： An automatic reversible arc assembly for a sprinkler includes a pair of primary stop members circumferentially spaced from each other by a first amount, and a pair of secondary stop members circumferentially spaced from each other by a second amount, different from the first amount. The primary stop members and the secondary stop members are coupled together and define a pivot assembly pivotable between a first position and a second position. A timer module cooperable with the pivot assembly is configured to hold the pivot assembly in the first position for a selectable period of time, after which the timer module enables the pivot assembly to pivot to the second position. The primary stop members are active in the first position, and the secondary stop members are active in the second position.

摘要： A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.

摘要： A quick connect coupler includes a female connector having a central bore and a plurality of recesses, and a male connector having a post insertable into the central bore. The male connector has a first tab row with a plurality of first tabs and a second tab row with a plurality of second tabs axially spaced from the plurality of first tabs. The first and second tabs are shaped corresponding to the recesses in the female connector. The first and second tab rows are circumferentially offset to effect a two- or multi-step connection between the female connector and the male connector.

摘要： A sprinkler module is cooperable with a sprinkler nozzle unit supporting a sprinkler nozzle to define a sprinkler configuration. The sprinkler module includes a cage attachable to the sprinkler nozzle unit and including a pair of struts, a cap connected to the cage via the pair of struts, and a deflector plate cooperable with the sprinkler nozzle and rotatably secured between the cap and the cage. The deflector plate includes a hub extending through the cap. A plate gear with gear teeth is secured to the hub and is rotatable with the deflector plate, and a cover assembly is connected to the cap. The cover assembly includes a brake gear coupled with a brake assembly, where the brake gear is disposed in a path of the gear teeth.

摘要： An irrigation system includes a network hub and a plurality of remote terminal units configured for wireless communication with the network hub. The remote terminal units are connected to a device for irrigation control or sensing, such as a valve for a sprinkler. The network hub is configured to transmit a wireless broadcast to the remote terminal units, in which the wireless broadcast includes a plurality of individual packets transmitted in succession, each of the plurality of individual packets including a network identifier associated with the network hub, a time remaining in a broadcast period of time, and an assignment map indicative of an assigned state for each of the plurality of remote terminal units.

摘要： A gooseneck pipe includes a first pipe half having a first radiused centerline curve, and a second pipe half fixed to the first pipe half and having a second radiused centerline curve. The first and second pipe halves define a flow path. Cross-sectional diameters of the first and second pipe halves vary along the flow path. The varying diameters of the first and second pipe halves serve to mitigate pressure losses due in part to Dean vortices or secondary flow patterns in the flow path when a fluid is turned in the gooseneck pipe.

摘要： A rotary nozzle sprinkler includes a base assembly with a bearing, a stem mounted rotatably in the bearing, and an elbow coupled at a proximal end to and rotatable with the stem and including an elbow bend. A nozzle is secured to a distal end of the elbow, and a diffuser assembly including a brake mechanism is cooperable with the elbow. By positioning the nozzle downstream of the elbow, the sprinkler can achieve a greater throw radius.
