PURPOSE:To keep constant a flow rate of a fire extinguishing agent by partitioning the interior of a cartridge into large and small chambers by a partition wall, cutting a seal plate blocking up an opening of the small chamber so that gas in the small chamber first flows out, and then letting gas in the large chamber flow out through a small hole. CONSTITUTION:A partition wall 4 is formed on a small cartridge 21, which is put in a main body 1 to concentrically dispose large and small chambers A, B. In case of use, a seal plate 7 is cut by a boring needle, whereby a gas space in a fire extinguisher is filled with gas in the small chamber B up to a fixed pressure to be jetted to the outside of a fire extinguisher. When gas in the small chamber B flows out, gas in the large chamber 7 flows into the small chamber B through a small hole 5, and further flows out to the outside. Thus, a fire extinguishing liquid is continuously jetted out. |
