Abstract
The invention relates to a fire extinguisher comprising a low-pressure tank (1) for the fire-inhibiting liquid (40) and a high-pressure tank (23) for spray propellant gas, situated in the low-pressure tank, where upon opening the high-pressure tank, the propellant expels the fire-inhibiting liquid, which is discharged through a nozzle (44). In order to permit fighting fires effectively from a greater distance than hitherto, in this fire extinguisher a pressure regulating valve (13) is arranged between the outlet of the spray propellant gas container (23) and the liquid reservoir of the low-pressure tank (1), which valve maintains the pressure of the propellant gas prevailing in the low-pressure tank after triggering and expelling fire-inhibiting liquid (40) through nozzle (44) at a preset level.
