ABSTRACT:
A spray nozzle includes an orifice disposed on a substantially planar discharge surface. An impingement surface is disposed opposite the orifice, the impingement surface forming an angle with a centerline of the orifice. The angle between the orifice centerline and the surface is less than 90 degrees. A deflection ridge bridges a gap between the impingement surface and the discharge surface. The deflection ridge encompasses a partial circumference of the nozzle. The nozzle includes a fluid fitting adapted for providing a pressurized fluid to the orifice.
