Some fire extinguishers are not directly pressurized, but have an external pressurized cartridge (or system of multiple cartridges) that is activated when pressure is needed.
Also, in portable fire extinguishers, there may be either a pressure cartridge or a manual pump for some kinds of extinguishers.
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.
