Sprinkler assembly
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.
1. A sprinkler comprising:
a sprinkler body having an outer wall;
an inner wall forming a central compartment disposed within said sprinkler body;
a riser having a nozzle connected to a water passage in selective communication with a water source; said riser being disposed within said central compartment, spaced from and movable relative to said central compartment;
a plurality of body compartments surrounding a top region of said central compartment and formed from said outer wall, said inner wall, a bottom surface and a plurality of compartment sidewalls; and,
a cover removably connected to form a top surface of said sprinkler and to cover a top opening of said plurality of body compartments.
2. The sprinkler of claim 1 , wherein said cover encloses all of said plurality of body compartments.
3. The sprinkler of claim 2 , wherein said cover further comprises an aperture through which a portion of said riser can pass through.
4. The sprinkler of claim 1 , wherein at least one of said plurality of body compartments includes a pilot valve.
5. The sprinkler of claim 1 , wherein said plurality of compartment side walls are removable.
6. The sprinkler of claim 1 , wherein at least one of said plurality of body compartments includes a solenoid.
7. The sprinkler of claim 1 , wherein said plurality of body compartments further comprise an integrally molded compartment.
8. The sprinkler of claim 1 , wherein said outer wall has a top portion having a first diameter and a lower portion having a second diameter; and wherein said second diameter is smaller than said first diameter.
9. The sprinkler of claim 8 , wherein said plurality of body compartments are located only within said top portion.
10. A sprinkler comprising:
a sprinkler body having an outer wall;
a riser disposed within said outer wall and having a nozzle to selectively rise out of said sprinkler body;
a riser wall forming an outer circumference of said riser;
a plurality of walls connected to said outer wall so as to form a plurality of body compartments surrounding a top end of said riser wall; said body compartments spaced apart from said riser wall; and,
a cover removably connected to form a top surface of said sprinkler and to cover a top opening of said plurality of body compartments.
11. The sprinkler of claim 10 , wherein said cover encloses all of said plurality of body compartments.
12. The sprinkler of claim 10 , wherein said outer wall has a top portion having a first diameter and a lower portion having a second diameter; and wherein said second diameter is smaller than said first diameter.
13. The sprinkler of claim 12 , wherein said plurality of body compartments are located only within said top portion.
14. The sprinkler of claim 10 , wherein said plurality of walls are removable.
15. The sprinkler of claim 10 , wherein at least one of said plurality of body compartments comprises a solenoid.
16. The sprinkler of claim 10 , wherein said plurality of body compartments include at least two compartments of different sizes.
17. A sprinkler comprising:
a sprinkler body having an outer wall;
a riser disposed within said outer wall and having a nozzle coupled to a water passage to selectively rise out of said sprinkler body;
an inner wall located around and positioned away from a perimeter of said riser, forming a compartment space;
a plurality of walls connected to said outer wall and said inner wall so as to form a plurality of body compartments within said compartment space and having a top opening at a top of said sprinkler; and,
a cover removably connected to form a top surface of said sprinkler and to cover said plurality of body compartments.
18. The sprinkler of claim 17 , wherein said cover encloses all of said plurality of body compartments.
19. The sprinkler of claim 18 , wherein each of said plurality of compartments further comprise a plurality of removable inserts.
20. The sprinkler of claim 17 , wherein at least one of said plurality of body compartments further comprises either a solenoid or a pilot valve.
21. The sprinkler of claim 17 , wherein said plurality of body compartments have varying sizes.
22. The sprinkler of claim 17 , wherein at least some of said plurality of body compartments each encompass different radial portions of said sprinkler body.
23. The sprinkler of claim 10 , wherein at least some of said plurality of body compartments each encompass different radial portions of said sprinkler body.
