A portable fire extinguisher designed to increase the discharge velocity and maximum throw distance of the extinguishant. A poppet type valve manually operable to open and close the extinguisher. Tappets placed outside the path of the discharging extinguishant and a smoothly finished discharge passage to provide an obstruction free discharge path. The obstruction free discharge path reduces turbulence and the resultant pressure drop in the extinguishant and increases both the discharge rate and throw distance.
