Irrigation sprinkler nozzle having deflector with micro-ramps

摘要

A spray nozzle for an irrigation sprinkler is provided, where the nozzle has a deflector that is configured with depending ribs. Each of the ribs has micro-structures that cooperate with other geometry of the rib and deflector to define a plurality of different micro-ramps for dividing the discharged water into different sprays having different characteristics that can be combined to achieve a spray pattern.

主权项

1. An irrigation spray nozzle comprising:
a nozzle body defining at least in part one or more fluid discharge flow passages for the passage of water; and a deflector to deflect water received from the one or more fluid discharge flow passages, the deflector having radially extending ribs depending from an underside of the deflector, adjacent ones of the ribs forming channels for water flow therebetween, a plurality of the ribs from the radially extending ribs, each rib of the plurality of the ribs having a pair of opposing sides, and each side comprises at least a first step extending into an adjacent one of the channels and at least partially in a radially extending direction such that a micro-ramp extends into the adjacent one of the channels for directing a portion of the water flow, the micro-ramp being spaced from a bottom of the channel defined by the underside of the deflector, the micro-ramps on the pair of opposing sides of each of the plurality of the ribs being spaced from each other.
