Fire extinguisher nozzle
View Patent ↗An extinguisher for minimizing fires includes a container for holding an extinguishing fluid, a propellant disposed within the container for expelling the fluid from the container if desired, and a nozzle for directing the fluid towards a fire. The nozzle has an input for receiving the fluid from the container and an outlet for directing the fluid towards the fire. The nozzle includes an expansion chamber disposed between the input and the outlet of the nozzle. The nozzle outlet has a restrictor for restricting flow of the fluid from the expansion chamber.
1. A fire extinguisher comprising a nozzle for directing an extinguishing fluid towards a fire, said nozzle having an input for receiving said fluid, an outlet for directing said fluid towards the fire, and an expansion chamber disposed between said input and said outlet of said nozzle and having a length dimension that is greater than a width dimensions, said nozzle having a restrictor downstream of said expansion chamber for restricting flow of said fluid from said expansion chamber; and
said input includes a base having a hollow ridged post that attaches to a hose.
2. The extinguisher of claim 1 further comprising a cone-like outlet disposed downstream of said restrictor.
3. The extinguisher of claim 1 , wherein said extinguishing fluid includes a FE-36™ fire suppressor.
4. The extinguisher of claim 1 , wherein said extinguishing fluid excludes water.
5. The extinguisher of claim 1 , wherein said base includes an outer threaded part.
6. The extinguisher of claim 1 , wherein said outlet includes an outer part having an outer threaded surface that mates with an inner threaded surface of said input.
7. The extinguisher of claim 1 , wherein said restrictor includes a bore that is narrower in diameter relative to said expansion chamber.
8. The extinguisher of claim 1 , wherein said nozzle includes a sleeve having a first threaded surface and a second threaded surface.
9. The extinguisher of claim 8 , wherein said input mates with said first threaded surface and said outlet mates with said second threaded surface.
10. The extinguisher of claim 1 , wherein said expansion chamber extends between a base and an outer part of said nozzle.
11. A fire extinguisher comprising a nozzle for directing an extinguishing fluid towards a fire, said nozzle having an input for receiving said fluid, an outlet for directing said fluid towards the fire, and an expansion chamber disposed between said input and said outlet of said nozzle and having a length dimension that is greater than a width dimensions, said nozzle having a restrictor downstream of said expansion chamber for restricting flow of said fluid from said expansion chamber; and
said outlet includes an outer part having an outer threaded surface that mates with an inner threaded surface of said input.
12. A fire extinguisher comprising a nozzle for directing an extinguishing fluid towards a fire, said nozzle having an input for receiving said fluid, an outlet for directing said fluid towards the fire, and an expansion chamber disposed between said input and said outlet of said nozzle and having a length dimension that is greater than a width dimensions, said nozzle having a restrictor downstream of said expansion chamber for restricting flow of said fluid from said expansion chamber; and
said nozzle includes a sleeve having a first threaded surface and a second threaded surface.
