Patent ID: 8668153

Claim:
A spray nozzle, comprising: a discharge surface; an orifice disposed on the discharge surface said orifice defining an axis and discharge surface being planar and orthogonal to axis; an impingement surface oppositely facing the orifice, the impingement surface oriented at an impingement angle measured relative to a centerline of the orifice, the impingement angle being 90 degrees or less; a deflection ridge, the deflection ridge bridging a gap between the impingement surface and the discharge surface and being flush with said impingement surface, the deflection ridge starting adjacent the discharge surfaces and terminating adjacent said impingement surface; a trough in said impingement surface and located adjacent the termination of said deflection ridge said trough being a hemispherical recess in said impingement surface thereby creating a discontinuity in the impingement surface from a generally planar portion to a tough portion and then a defecting ridge; a fluid fitting in fluid connection with the orifice, the fluid fitting adapted to receive a pressurized fluid.
