Another obsolete method (the soda-acid extinguisher) included a cylinder of sodium bicarbonate solution with a bottle of sulfuric acid, none of which was pressurized. When you inverted the extinguisher or pressed a plunger to spill the acid into the bicarb, the resulting CO2 gas would pressurize the container and blow the bicarb/water/acid solution out through the hose aimed at the fire.
