Rotating high pressure air and water nozzle
A rotating high pressure air and water nozzle is disclosed. The nozzle includes a head adapted to rotate, a housing adapted to secure the head therein, and a plurality of passageways disposed through the head. In addition, the nozzle includes a supply port disposed at a first end of each of the passageways, where each supply port has a funnel shape adapted to direct fluid into each passageway to reduce hydraulic losses, and a discharge port disposed at an opposing end of each of the passageways adapted to discharge a jet of fluid. Each discharge port is offset from the respective supply port to cause the head to rotate when fluid flows through the passageways.
1. A nozzle comprising:
a head having a circular periphery;
a housing having the head secured therein;
a circular support ring adjoining an inside wall of the housing and secured to the circular periphery of the head in order for the head to rotate therein;
a plurality of passageways disposed through the head;
a supply port disposed at a first end of each of the passageways; and
a discharge port disposed at an opposing end of each of the passageways, wherein each discharge port is offset from the respective supply port and configured to cause the head to rotate when fluid flows through the passageways.
2. The nozzle of claim 1 , the nozzle further comprising a shroud about the head secured to the housing, wherein the shroud having a sidewall about its periphery extending beyond the head.
3. The nozzle of claim 2 , the nozzle further comprising a connector secured to the housing to connect a pressurized fluid source to the housing.
4. The nozzle of claim 3 , wherein the pressurized fluid source is water, air, or any combination thereof.
5. The nozzle of claim 4 , wherein the discharge ports are configured to generate a dynamic spray pattern.
6. The nozzle of claim 5 , the shroud comprises a lower edge configured to break up soil when the lower edge is pushed into the soil.
7. The nozzle of claim 6 , further comprising a gasket interposed between the housing and shroud to form a watertight connection.
8. The nozzle of claim 7 , wherein the plurality of passageways are spaced equally from one another on the head.
9. The nozzle of claim 8 , wherein each supply port having a funnel shape.
10. The nozzle of claim 1 , wherein an annular lubricating channel is interposed between the inside wall of the housing and an upper portion of the head and configured to be in fluid communication with the fluid.
11. The nozzle of claim 1 , wherein the plurality of passageways are configured to withstand a fluid at a pressure of at least 1,000 pounds per square inch and a flow of at least 10 gallons per minute.
12. The nozzle of claim 1 , wherein the head having a solid center core.
13. A nozzle comprising:
a head comprising a right circular cylinder;
an annular support ring;
a rolling bearing securing the annular support ring around a periphery of the head;
a plurality of passageways disposed through the head;
a supply port disposed at a first end of each of the passageways; and
a discharge port disposed at an opposing end of each of the passageways, wherein each discharge port is offset from the respective supply port and configured to cause the head to rotate when fluid flows through the plurality of passageways.
