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.

What is claimed is: 1. A fluid spray nozzle, comprising: a discharge surface; an orifice disposed on the discharge surface; 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 less than 90 degrees whereby a portion of fluid will be deflected back to along the discharge surface; a radiused deflection ridge, the deflection ridge bridging a gap between the impingement surface and the 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. 2. The spray nozzle of claim 1, wherein the deflection ridge comprises a filleted corner. 3. The spray nozzle of claim 2, wherein the filleted corner smoothly joins with the impingement surface. 4. The spray nozzle of claim 1, wherein the deflection ridge comprises two filleted corners, the filleted corners intersecting at an angle defining the spray angle. 5. The spray nozzle of claim 4, wherein the two filleted corners smoothly join with the impingement surface. 6. The spray nozzle of claim 4, wherein the spray angle is about 100 degrees to about 160 degrees. 7. The spray nozzle of claim 1, wherein the deflection ridge comprises a filleted corner and a sharp corner, the filleted corner and the sharp corner intersecting at an angle defining the spray angle. 8. The spray nozzle of claim 7, wherein the spray angle is about 90 degrees to about 120 degrees. 9. The spray nozzle of claim 7, wherein the filleted corner and the impingement surface join at a sharp ridge. 10. The spray nozzle of claim 7, wherein the filleted corner extends past the intersection of the filleted corner and the sharp corner and forms a spherical indentation therein. 11. The spray nozzle of claim 7, wherein the sharp corner further comprises a trailing edge curve, the trailing edge curve extending towards the filleted corner at a distal end of the sharp corner. 12. The spray nozzle of claim 7, wherein the sharp corner further comprises a leading edge curve, the leading edge curve extending away from the filleted corner at the intersection of the filleted corner and the sharp corner. 13. The system of claim 1, wherein the spray head is interchangeable on the body. 14. The nozzle of claim 1 wherein the deflection ridge is filleted and V-shaped. 15. The nozzle of claim 1 wherein the deflection ridge is filleted and bisected into two portions, the portions being in a non-linear angular relation to each other. 16. A method of constructing a fluid dispersal nozzle, having a discharge surface, an orifice in the discharge surface, and an impingement surface comprising: a. providing an orifice for conducting a pressurized fluid onto an impingement surface, b. locating the impingement surface at a deflection angle measured relative to a centerline of the orifice, the angle being 90 degrees or less; c. deflecting the fluid along a radiused deflection ridge bridging a gap between the impingement surface and the discharge surface; d. locating the orifice orthogonally relative to the discharge surface; and e. limiting the cross sectional extent of the impingement surface so that its extent is less than the extent of the discharge surface; so that fluid exiting the orifice will generally strike the impingement surface and subsequently flow along the discharge surface before being discharged from the nozzle. 17. The method of claim 16, wherein the deflection angle is generally 85 degrees. 18. The method of claim 16, wherein restricting the exit plume to a limited circumferential angle further comprises deflecting the impingement flow using a filleted corner. 19.

A spray nozzle with a limited spray circumference for spraying a fluid in a predetermined spraying angle, comprising: a substantially planar discharge surface; central orifice substantially orthogonally disposed on the discharge surface; a deflection ridge, having an upper and lower edge, said lower edge extending from said planar surface and being formed to limit the fluid flow by its curved surface; an impingement surface, extending from the upper edge of said deflection ridge and oppositely facing the orifice, the impingement surface oriented at an impingement angle measured relative to a centerline of the orifice, the impingement angle being less than 90 degrees; said impingement surface having a peripheral edge and wherein said discharge surface also has a peripheral edge, said edge extending beyond said impingement surface peripheral edge, so that fluid flow flowing along said impingement surface will generally be flow along said discharge surface before exiting the nozzle; the deflection ridge bridging a gap between the impingement surface and the discharge surface, the deflection ridge defining a spray angle which limits the discharge of fluid; and a fluid fitting in fluid connection with the orifice, the fluid fitting adapted to receive a pressurized fluid.
