Abstract:
The present invention includes an improved sprinkler design having a magnetic sensing system for determining the position of the riser nozzle, a waterproofed motor housing and related cables, configurable sprinkler body compartments, and a pilot valve with a check valve assembly, both of which are located within the sprinkler body.
An improved sprinkler nozzle comprises a nozzle body having a nozzle received in a recessed seat provided in a peripheral wall of the nozzle body. The nozzle is formed with a plurality of nozzle ports formed by the radially outer ends of a plurality of vertically flexible nozzle tubes. The flow volume of the water stream being thrown by the sprinkler nozzle is adjusted by selectively operating a flow volume adjustment member carried on the nozzle body to selectively open or close various of the nozzle tubes in various possible combinations. The flow volume of the nozzle will comprise the combined or aggregate flow volumes of the water sub-streams being thrown by those nozzle tubes that are left open. The trajectory of the water stream being thrown by the sprinkler nozzle is adjusted by selectively operating a trajectory adjustment member carried on the nozzle body to bend the flexible nozzle tubes about their vertically fixed, radial inner ends to raise and lower the radial outer ends of the nozzle tubes.
A fixed spray sprinkler nozzle has adjustable arc coverage. The nozzle has a nozzle body with sideward facing water discharge slots including a bottom slot and a top slot. Flow blocking skirts control the open length of each of the slots. The bottom slot is fixed on the nozzle body, but the top slot is rotatable on the nozzle body, in concert with the opening or unblocking of the bottom slot's length, from a position overlying the bottom slot to a position directed in an opposite direction from the bottom slot. When the bottom slot is fully open, the top slot may then be progressively opened over its entire length. Thus, the arc coverage can be infinitely adjusted over the combined circumferential length of both the bottom and top slots together. The slots have a grooved bottom wall to provide smooth water flow and good pattern definition at each side of the selected arc.
An improved sprinkler comprises a nozzle body having a nozzle received in a recessed seat provided in a peripheral wall of the nozzle body. The nozzle body has a rotatable upper cover. A cam surface is formed on the cover and extends down into engagement with the nozzle. The cam surface is shaped to push the nozzle at least partially out of its seat during rotation of the cover to allow the user to be able to grip the nozzle and complete its removal by pulling outwardly on the nozzle. The cover also includes a locking rib which can be brought to bear against the nozzle when the nozzle is fully received in its seat to help retain the nozzle in place. Desirably, the cover also includes a radius adjustment screw which is located in front of and spaced away from the front end of the nozzle such that the screw does not in any way engage or bear against the nozzle to prevent damage to the nozzle from the screw.
