Patent ID: 7780093

Claim:
A spray nozzle system having at least two separable components, a spray head and a nozzle body, comprising: the nozzle body comprising a substantially planar discharge surface, an orifice disposed on the discharge surface, and a fluid fitting in fluid connection with the orifice, the fluid fitting adapted to receive a pressurized fluid; the spray head removably mounted to the body, the spray head comprising: a substantially planar impingement surface, the impingement surface oppositely facing the discharge surface, the impingement surface oriented at an impingement angle measured relative to a centerline of the orifice, the impingement angle being, less than 90 degrees; and a concave deflection ridge, the deflection ridge bridging a gap between the substantially planar impingement surface and the substantially planar discharge surface, the deflection ridge defining a spray angle which limits the discharge of fluid, said orifice is laterally spaced apart from the deflection ridge and a fluid fitting in fluid connection with the orifice, the fluid fitting adapted to receive a pressurized fluid; a stepped down recessed mounting surface in the nozzle body abutting the discharge surface; and a stepped up extension mounting surface in the removable spray head sized to engage said step down recessed mounting surface so that when said spray head is affixed to the nozzle body, the spray head is prevented from moving relative to the nozzle body in response to fluid pressures.
