Abstract:
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.
