Abstract: The invention relates to an apparatus for impulse fire extinguishing which includes an ejection tube for storing fire fighting powder or liquid and a container for storing gaseous propellant. The container is connected to the ejection tube. A quick action closing element is located between the container and the ejection tube and is arranged in the container to move freely therein for separating the container into two parts: a propellant chamber and an equalizing chamber. The ejection end of the ejection tube extends into the atmosphere, and the input end thereof is arranged in the propellant chamber in a way that it is open in a first position of the quick action closing element and closed in another position thereof.
