Abstract

The fire extinguisher using powder has a bottle of the powder and with a filler opening sealed by a plug, while a discharge pipe leads from inside the bottle to a valve with sprayer mouth piece. A high pressure gas supply is connected via a hand release via a hand pipe extending inside the bottle. The gas supply pipe (27) is connected to a diffuser (28) near the base of the bottle (4) and having gas ports so as to fluidise the power before discharge to the mouthpiece (18). the diffuser can be a flexible elastic tube connected to the supply pipe, and either porous or with a series of holes in the surface.
