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. A deflection ridge bridges a gap between the impingement surface and the discharge surface. Adjacent the deflection ridge is a further trough which extends into the impingement surface. The nozzle includes a fluid fitting adapted for providing a pressurized fluid to the orifice.
