Abstract: A fire extinguishing device comprises an extinguishing agent tank and pressurised gas generation means such that the generated gas can enter into the tank when the extinguishing agent is to be ejected on a fire area. The device according to the invention also comprises means of regulating the pressure inside the extinguishing agent tank: thus, the pressure inside the tank remains controlled with time, with a profile predetermined by the user as a function of regulatory parameters and criteria, in order to optimise the action of the extinguishing agent and the necessary quantity.

Abstract: A fire extinguishing apparatus and method are proposed, comprising: a container configured to receive and retain a fire extinguishing agent; a pressure generator coupled to the container to have a generated pressure act upon the fire extinguishing agent to expel the fire extinguishing agent over an expel-exit of the container. Due to a separator which is placed within the container so that the fire extinguishing agent and the pressure generator are separated, it is advantageously possible to provide a pressure effect on the extinguishing agent without any risks of mixing a pressurized gas from the pressure generator and the extinguishing agent, especially by the ignition phase of the pressure generator, wherein only the extinguishing agent has to be expelled out of the container. Furthermore some means related to the separator will be proposed for improving the expelling of the extinguishing agent out of container.
