초록

A nozzle for an irrigation sprinkler is provided, where the nozzle includes a sealing pad for reducing the distance relative to a seal of an irrigation device when the nozzle is in a retracted position to restrict the entry of grit and other debris into the irrigation device.

대표청구항 ▼

1. An irrigation nozzle attachable to a riser of a pop-up irrigation device, the nozzle configured for forming a seal or a reduced width opening relative to a seal of the irrigation device when the riser is in a retracted position and for discharging water when the riser is in an extended position, the nozzle comprising: a base having a first end portion adapted for attachment to the riser and a second end portion;a deflector to deflect water through at least one discharge opening, the deflector having an axial span positioned between the at least one discharge opening and a top of the deflector and extending circumferentially about the deflector, the span having an outwardly projecting, sealing pad extending substantially continuously about the circumference of the span and positioned radially outwardly beyond the at least one discharge opening and radially inwardly relative to the top of the deflector, the sealing pad being configured for reducing the distance relative to the seal of the irrigation device when the riser is in a retracted position as compared to at the at least one discharge opening to restrict entry of grit and other debris into the irrigation device. 2. The irrigation nozzle of claim 1, wherein the sealing pad is continuous. 3. The irrigation nozzle of claim 1, wherein the sealing pad has at least one gap through which water can drain into the irrigation device when the riser is in the retracted position. 4. The irrigation nozzle of claim 3, wherein the sealing pad has four or fewer gaps. 5. The irrigation nozzle of claim 3, wherein the sealing pad has more than four equally-spaced gaps. 6. The irrigation nozzle of claim 1, wherein the sealing pad has a constant, axially extending width. 7. The irrigation nozzle of claim 1, wherein a plurality of discharge openings are provided between ribs depending from an underside of the deflector. 8. The irrigation nozzle of claim 7, wherein the deflector is adapted to rotate relative to the base when impinged by water. 9. The irrigation nozzle of claim 7, wherein the sealing pad terminates with a step adjacent to the plurality of discharge openings, the step being helical such that the sealing pad has a varying, axially extending width. 10. The irrigation nozzle of claim 7, further comprising: a first helical surface fixed relative to the base;a second helical surface moveable relative to the base, the first and second helical surfaces cooperating to define an arcuate flow passage adjustable in size to determine an arc of spray distribution upon relative rotation between the first and second helical surfaces. 11. The irrigation nozzle of claim 10, wherein a depending neck of the deflector includes the first helical surface and a collar rotatable relative to the deflector and the base includes the second helical surface. 12. The irrigation nozzle of claim 11, wherein the neck of the deflector includes a plurality of flow notches disposed about its outer periphery, the flow notches are aligned with the channels of the deflector. 13. The irrigation nozzle of claim 11, wherein means are provided for biasing the second helical surface into a plurality of preset positions relative to the first helical surface. 14. The irrigation nozzle of claim 13, wherein a plurality of the depending ribs of the deflector have an outwardly-extending step at least partially along the length of the ribs such that a micro-ramp extends into the channels for directing a portion of the water flow. 15. The irrigation nozzle of claim 1, wherein the deflector includes means for discharging more than one discrete spray. 16. The irrigation nozzle of claim 1, in combination with a pop-up irrigation device having a riser, the nozzle configured for reducing the distance relative to a seal of the irrigation device when the riser is in a retracted position and for discharging water when the riser is in an extended position. 17. The irrigation nozzle of claim 16, wherein the sealing pad is configured for sealing against a seal of the irrigation device when the riser is in a retracted position. 18. A method of irrigating using the spray nozzle and pop-up irrigation device of claim 17, the method comprising: discharging water through the at least one discharge openings when the riser is in the extended position;forming a seal between the sealing pad of the deflector of the nozzle and the seal of the irrigation device when the riser is in the retracted position. 19. The method of claim 18, further comprising draining fluid into the irrigation device when the riser is in the retracted position through at least one drain path. 20. The method of claim 19, wherein the drain path is a gap in the sealing pad.
