Fire suppressant device and method, including expansion agent

1. A fire suppressant device, comprising:

a housing defining a hollow cylinder; and

a column disposed at least partially within the hollow cylinder, the column defining an expansion chamber configured to receive an expansion agent and an extinguishing agent chamber configured to receive a fire extinguishing agent,

wherein the column includes a piston end cap and a piercing end disposed opposite the piston end cap, the piercing end being configured to pierce a container to deliver the fire extinguishing agent to an inside space of the container when the column extends from the housing, and

wherein the column is configured to extend from the housing under a pressure generated by activation of the expansion agent contained within the expansion chamber.

2. The fire suppressant device of claim 1 , wherein the column further includes one or more apertures configured to permit delivery of the fire extinguishing agent therethrough into the inside space of the container.

3. The fire suppressant device of claim 1 , wherein the column further includes one or more baffles configured to permit delivery of the fire extinguishing agent therethrough into the inside space of the container.

4. The fire suppressant device of claim 1 , wherein the column include a threaded portion at the end opposite the piercing end.

5. The fire suppressant device of claim 4 , wherein the piston end cap includes a threaded portion configured to engage with the threaded portion of the end of the column.

6. The fire suppressant device of claim 4 , wherein the piston end cap includes a cap portion, the housing includes a stop structure provided in the hollow cylinder, and the cap portion is configured to abut the stop structure to prevent the column from separating from the housing after the column is extended.

7. The fire suppressant device of claim 4 , wherein the piston end cap includes an aperture, through which an igniter lead is configured to extend into the expansion chamber.

8. The fire suppressant device of claim 7 , wherein the igniter lead is configured to activate the expansion agent in response to receiving a signal from a controller indicating detection of a smoke, heat, or fire within the container.

9. The fire suppressant device of claim 1 , wherein the expansion chamber and the extinguishing agent chamber are separated by a separator.

10. The fire suppressant device of claim 9 , wherein the separator includes a timing fuse configured to delay ignition of the fire extinguishing agent until the timing fuse burns through to the extinguishing agent chamber and ignites the fire extinguishing agent.

11. The fire suppressant device of claim 1 , wherein

the expansion chamber includes the expansion agent configured to generate a pressurized gas when activated.

12. The fire suppressant device of claim 1 , wherein the extinguishing agent chamber is configured to receive a plurality of supplies of the fire extinguishing agent, and wherein a plurality of fuses are provided to ignite each of the supplies independently of one another at different times.

13. The fire suppressant device of claim 1 , wherein

the expansion chamber includes the expansion agent, which includes a moldable material.

14. A fire suppressant device, comprising:

a housing defining a hollow cylinder; and

a column disposed at least partially within the hollow cylinder, the column including a first end having a piercing end, a second end having an end cap, an expansion chamber, and an extinguishing agent chamber, the expansion chamber being located adjacent the second end having the end cap, and the extinguishing agent chamber being located adjacent the first end having the piercing end,

wherein the expansion chamber is configured to receive an expansion agent, and the extinguishing agent chamber is configured to receive a fire extinguishing agent, and

wherein the column is configured to extend from the housing upon activation of the expansion agent to enable the piercing end to pierce a container.

15. The fire suppressant device of claim 14 , wherein the column is configured to extend from the housing upon ignition of the expansion agent contained in the expansion chamber.

16. The fire suppressant device of claim 14 , wherein the column further includes one or more apertures configured to permit delivery of the fire extinguishing agent therethrough into an inside space of the container after the piecing end pierces the container.

17. The fire suppressant device of claim 14 , wherein the column further includes one or more baffles configured to permit delivery of the fire extinguishing agent therethrough into an inside space of the container after the piecing end pierces the container.

18. The fire suppressant device of claim 14 , wherein the end cap includes an aperture, through which an igniter lead is configured to extend into the expansion chamber.

19. A method for delivering a fire extinguishing agent into a container to suppress a fire within the container, comprising:

providing a device including a housing defining a hollow cylinder, a column disposed at least partially within the hollow cylinder and configured to extend from the hollow cylinder when activated, the column defining a piercing end, an expansion chamber configured to receive an expansion agent, and an extinguishing agent chamber configured to receive a fire extinguishing agent;

igniting the expansion agent to extend the column from the hollow cylinder such that the piercing end pierces the container; and

delivering the fire extinguishing agent to an interior of the container.
