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.
Claims46
A 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 90 degrees or less;
- a 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;
- and
- a fluid fitting in fluid connection with the orifice, the fluid fitting adapted to receive a pressurized fluid.
A spray nozzle system, comprising:
- a body comprising a 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;
- and
- a spray head removably mounted to the body, the spray head comprising:
- an 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 90 degrees or less;
- and
- a 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.
A method of dispersing fluid, comprising:
- discharging a pressurized fluid from an orifice onto an impingement surface, the impingement surface oriented at a deflection angle measured relative to a centerline of the orifice, the angle being less than 90 degrees;
- deflecting the fluid at the impingement surface to form an impingement flow;
- and
- deflecting the impingement flow at a deflection ridge to restrict an exit plume to a limited circumferential angle.
A spray nozzle, comprising:
- a body, comprising:
- a substantially planar discharge surface;
- a fluid fitting on an end of the body away from the discharge surface;
- and
- an orifice disposed on the discharge surface and in fluid connection with the fluid fitting;
- and
- a spray head removably attached to the body, comprising:
- a substantially planar sealing surface interfaceable with the discharge surface of the body, the sealing surface having a generally triangular shape with a triangular base and a rounded triangular tip opposite the triangular base;
- a planar impingement surface indented in the sealing surface, the impingement surface oppositely facing the orifice when the spray head is attached to the body, the impingement surface oriented at an impingement angle measured relative to a centerline of the orifice, the impingement angle being 90 degrees or less;
- and
- a deflection ridge at the intersection of the impingement surface and the sealing surface, the deflection ridge being at least in part adjacent to the triangular base of the sealing surface.
