Abstract: A sprinkler controller includes a central portion and a peripheral switch being moveable in an arcuate path relative to the central portion. The peripheral switch may be a peripheral dial that can be rotated about the central portion. The dial may be rotated to select a particular mode of the sprinkler controller. A display screen is positioned on the central portion. At least two controls are also positioned on the central portion. When a mode is selected by using the peripheral dial, the user may then employ the controls (and the display on the screen) to modify the settings for the sprinkler controller. A method of using the sprinkler controller is also disclosed.

Abstract: A modular sprinkler controller is disclosed. The modular sprinkler controller includes a base unit and one or more add-on modules. The base unit and each add-on module include valve terminals for communicating with coupled sprinkler valves. The base unit includes one or more communication connection points for communicating with adjacent add-on modules. Each add-on module may include two connection points for communication with an adjacent base unit or add-on module. In one embodiment, the base unit and add-on modules are arranged in a piggyback configuration. An add-on module for use with a base unit is also disclosed.

Abstract: A sprinkler having an adjustable spray pattern is disclosed. The sprinkler may include a housing. The housing may include an inlet portion disposed to receive water and an outlet portion. The outlet portion may include a first outlet aperture and a second outlet aperture. The housing may include a cam disposed upstream of the first and second water outlet apertures. The cam may be rotated to a first position and a second position. The cam may include a first open portion that is rotatable about a cam axis. The cam may include a second open portion that is rotatable about the cam axis. The cam may further include a third open portion that is rotatable about the cam axis.

Abstract: A timer that facilitates a user's scheduling and controlling of the operation of an irrigation system for irrigating a property, the timer including a base unit electrically connected to the valve, and a handheld unit including a power source, a CPU, a valve controller, a memory device, and software stored in the memory device. The irrigation system includes a valve, a conduit, and a distribution unit that distributes fluid over an irrigation zone of the property. The handheld unit is used remotely from the base unit to modify an irrigation schedule of the valve. The irrigation schedule is used with the valve controller to operate the valve according to the irrigation schedule through communication with the base unit.

Abstract: A sprinkler has a housing with an inlet portion and an outlet portion in which a first outlet aperture is formed. The first outlet aperture may cooperate with other outlet apertures to define a spiral shape. A cam is disposed upstream of the first outlet aperture. The cam is rotatable about a cam axis to cover varying portions of the outlet apertures. After moving through the outlet apertures, water strikes a deflector and is sprayed outward from the head. The orientation of the cam establishes an arc angle through which water is sprayed, including a full-circle spray pattern. The deflector may be stationary or rotatable. In one alternative configuration, the outlet apertures and each leads to a different strip nozzle. The cam has an open portion that can be rotated into alignment with each of the outlet apertures to determine which of the strip nozzles are active.

Abstract: A sprinkler valve wiring apparatus and method are provided. An irrigation system has a plurality of valves designed to be electrically activated by a control unit. Valve wires extend from the valves to a junction unit. Control unit wires extend from the control unit to the junction unit, and are electrically coupled to the valve wires within the junction unit. The control unit wires include a common wire and a plurality of hot wires. Each hot wire is coupled to a corresponding valve, while the common wire is coupled to all of the valves by the junction unit. The junction unit utilizes resilient blocking members with frangible portions that block unused wire receptacles and can be removed to provide watertight access to the remaining wire receptacles. The junction unit is fixed in place via an anchoring mechanism such as a pipe clip or stake.

Abstract: A sprinkler valving apparatus and method are provided. An irrigation system has a plurality of valves designed to be electrically activated by a control unit. Each valve may have a first diaphragm that is flexible to control irrigation water flow through the valve. Each of the valves may have a solenoid isolated from irrigation water within the valve by a second diaphragm. The first and second diaphragms are separated by an interior divider with an orifice that can be blocked or unblocked via flexure of the second diaphragm to trigger motion of the first diaphragm. The second diaphragm is actuated by a magnetically actuatable plunger of the solenoid, which extends through an aperture of an interior retainer to reach the second diaphragm. The second diaphragm has a peripheral ring to ensure that it is movable even when negative outlet pressure is applied to the valve.
