Abstract

What is new about this nozzle is its ability to extend the reach of a fluid stream from a pressurized hose by means of low-friction design and nozzle aperture extension. The combination of low friction design and aperture extension produces an effect which is superior to that which might be anticipated by adding an extension to a hose. The nozzle is made of strong, lightweight, rigid materials. The extended stream reach exceeds the length of the long nozzle itself.

Claims

1. A nozzle for connection to a pressurized hose, comprising:

a hose-coupling device;

a first pipe with a first diameter;

a nozzle tip;

a nozzle aperture; and

a fluid acceleration zone,

wherein the fluid acceleration zone comprises a low friction area.

2. The nozzle according to claim 1, wherein an overall length of the nozzle is between 50 inches and 204 inches.

3. The nozzle according to claim 1, wherein a length of the low friction area is sufficient to reduce turbulence and friction near the nozzle aperture.

4. The nozzle according to claim 1, wherein the nozzle further comprises a ball valve.

5. The nozzle according to claim 1, wherein the nozzle further comprises a second pipe with a second diameter.

6. The nozzle according to claim 5, wherein the first diameter is different than the second diameter.

7. The nozzle according to claim 1, wherein the first diameter is between ⅜

inches and 3 inches.

8. The nozzle according to claim 5, wherein the second diameter is between ⅜

inches and 3 inches.

9. The nozzle according to claim 5, wherein the nozzle further comprises a reducer coupling used to connect the second pipe to the first pipe.

10. The nozzle according to claim 1, wherein the nozzle tip is a straight stream nozzle tip, an air-aspirating foam nozzle tip, or an adjustable stream/fog nozzle tip.

11. The nozzle according to claim 1, wherein the nozzle further comprises a foam induction tee.

12. The nozzle according to claim 11, wherein the nozzle further comprises a ball valve connected to the foam induction tee.

13. The nozzle according to claim 1, wherein the first pipe comprises glass-fiber reinforced resin-based tubing.

14. The nozzle according to claim 5, wherein the second pipe comprises glass-fiber reinforced resin-based tubing.

15. The nozzle according to claim 5, wherein the first pipe comprises glass-fiber reinforced resin-based tubing and the second pipe comprises glass-fiber reinforced resin-based tubing.

16. The nozzle according to claim 1, wherein the nozzle is made from one or more materials selected from the group consisting of plastics, composites and metals.

17. The nozzle according to claim 1, wherein each component of the nozzle is made from thermoplastic, anodized aluminum, brass, or fiber-reinforced plastic.

18. The nozzle according to claim 1, wherein the nozzle further comprises a support leg.

19. The nozzle according to claim 18, wherein the support leg is removeably attached to the nozzle.
