Abstract
A propulsion device for an agent, such as an extinguishing or cooling agent, contained in a cavity has at least a cap and a port configured to open above a calibrated pressure inside the cavity. A pressure generator is fastened to the cap and triggers the propulsion of the agent. The pressure generator has at least two containers, each having an exit ending inside the cavity and releasing a propulsion gas. At least one container is pressurized with an inert-type gas, such as helium, suited for minimal temperature fluctuations induced inside the cavity during a relief of pressure of the gas from at least one of the containers. When the gas expands it is the direct mechanical propellant of the agent.
