Patent ID: 8534577

Claim:
A flat jet fluid nozzle, comprising: a lower nozzle plate including a lower impingement surface formed therein, at least one fluid intake port disposed at an inner end of the lower impingement surface and a lower orifice edge disposed along an outer end of the lower impingement surface; an upper nozzle plate including an upper impingement surface formed therein and an upper orifice edge disposed along an outer end of the upper impingement surface, wherein the lower and upper orifice edges are opposed; the lower and upper impingement surfaces each including a plurality of sculpted radial flutes, each flute emanating from a central axis passing through the lower and upper nozzle plates and each flute extending to the opposed lower and upper orifice edges, the opposed lower and upper orifice edges forming a slotted orifice; a compressible seal configured for sealing the lower nozzle plate to the upper nozzle plate, such that the lower and upper impingement surfaces are opposed toward one another, thereby forming a fluid channel between the impingement surfaces, the fluid channel configured to direct pressurized fluid from the at least one fluid intake port to the slotted orifice formed between the opposed lower and upper orifice edges; and a droplet size adjustment mechanism configured for attachment to the upper and lower nozzle plates for selectively controlling fluid droplet size ejected from the slotted orifice by selectively compressing the compressible seal.
