Abstract: An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.

Abstract: Several embodiments provide cycle and soak irrigation control units, comprising: a housing; a plurality of pairs of actuation line connectors comprising input connectors to couple with output actuation lines of a separate irrigation controller, and output connectors to couple with actuatable devices; a plurality of electrical pathways each coupling a respective input connector to a corresponding output connector and allowing an activation signal to be passed; at least one switch configured to selectively allow or interrupt activation signals to pass to a corresponding output connector; and a timing control circuit controlling the switch, based on an application of an activation signal on an input connector, a duration of a series of cycle-on timings during which the activation signal is emitted from the output connector to activate an actuatable device and soak-off timings during which the activation signal is prevented from being emitted deactivating the actuatable device.

Abstract: A specialty nozzle is provided having a pattern adjustment valve that may be adjusted to irrigate a substantially rectangular irrigation area. The nozzle may be further adjusted to irrigate three different substantially rectangular irrigation areas. The nozzle is adjustable to function as a left strip nozzle, right strip nozzle, and side strip nozzle. The strip irrigation setting may be selected by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a flow reduction valve to set the size of the rectangular irrigation areas and may be adjusted by actuation of an outer wall of the nozzle. Other specialty nozzles are provided having a fixed pattern template to irrigate a rectangular area, such as left strip, right strip, or side strip.

Abstract: Rotary nozzles are provided that produce multiple discrete water streams for the irrigation of a substantially rectangular irrigation area. The nozzles may be designed to function as one of a left corner strip nozzle, right corner strip nozzle, and side strip nozzle. Each nozzle includes a particular type of nozzle housing with multiple flow channels oriented to irrigate a rectangular area in a certain position relative to the nozzle. The side strip nozzle includes one or more groups of two flow channels that are asymmetric with respect to one another. Further, each nozzle includes a deflector that rotates in either a clockwise or counterclockwise direction, depending on the position of the rectangular irrigation area relative to the nozzle. By matching deflector rotation with the position of the rectangular irrigation area, the uniformity of irrigation within the rectangular irrigation area can be increased.

Abstract: Several embodiments provide cycle and soak irrigation control units, comprising: a housing; a plurality of pairs of actuation line connectors comprising input connectors to couple with output actuation lines of a separate irrigation controller, and output connectors to couple with actuatable devices; a plurality of electrical pathways each coupling a respective input connector to a corresponding output connector and allowing an activation signal to be passed; at least one switch configured to selectively allow or interrupt activation signals to pass to a corresponding output connector; and a timing control circuit controlling the switch, based on an application of an activation signal on an input connector, a duration of a series of cycle-on timings during which the activation signal is emitted from the output connector to activate an actuatable device and soak-off timings during which the activation signal is prevented from being emitted deactivating the actuatable device.
