Claim 0:
1. A portable fire extinguisher including a chamber configured to be filled with a dry fire suppressant material and to be pressurized with gas from a pressurized gas cartridge, the portable fire extinguisher further including a flow path for releasing the fire suppressant material from the chamber, the portable fire extinguisher comprising:
an integral siphon tube having a first tube end coupled to the flow path and a second tube end disposed inside the chamber;
a puncture pin disposed in the chamber such that the puncture pin releases liquefied gas from the pressurized gas cartridge directly into the chamber such that a stream of liquefied gas enters the chamber in an orientation that is parallel to an axis of the siphon tube and is directed at the dry fire suppressant material, the pressurized gas cartridge located externally from the chamber;
at least two fluffing arms disposed in the chamber and configured to agitate the dry fire suppressant material in the chamber when the integral siphon tube is rotated, wherein each fluffing arm includes a first end coupled to the integral siphon tube and the fluffing arm extends radially away from the integral siphon tube to a second end inside the chamber, an upper surface of the fluffing arm sloped along its length away from the first tube end; and
a support gusset coupled to the integral siphon tube and where a portion of the support gusset extends to a point adjacent to the second end one of the at least two fluffing arms, wherein the support gusset extends radially away from the integral siphon tube inside of the chamber and supports at least a portion of the fluffing arm, the support gusset adapted to resist a compressive force from the stream of liquefied gas from the pressurized gas cartridge applied to the fluffing arm where such force is applied in a direction that is parallel to the axis of the integral siphon tube.
