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.

1. A device for propelling an agent, comprising: a cavity configured to contain the agent;a cap mounted to the cavity;a port configured to open above a calibrated pressure inside the cavity; anda pressure generator coupled to the cap and configured to trigger propelling the agent from the cavity,wherein the pressure generator comprises at least two containers, and each one of the containers has an exit ending inside the cavity,wherein a first one of the containers is a pressurized container that stores a first propulsion gas that acts on the agent when released and a second one of the containers is a pressurized container that stores a second propulsion gas that acts on the agent when released, andwherein at least one of the first and second gas is an inert gas that is selected to have minimal temperature fluctuations induced in the cavity during a pressure relief of the inert gas from at least one of the containers, wherein the inert gas in expansion is the direct propellant of the agent;wherein at least one of the two containers is placed in the cavity by an upholding mounting fastened on the cap. 2. The device according to claim 1, wherein the inert gas is helium (He) in gaseous form. 3. The device according to claim 1, wherein the pressure generator comprises at least an opening module at the exits of the containers, wherein the opening module comprises at least one pyrotechnic valve with a minimal energy grade and sufficient to trigger the opening of one of the exits. 4. The device according to claim 1, wherein the containers are configured to be triggered to expansion by at least one of distinct electrical triggering and delayed triggering. 5. The device according to claim 1, wherein the containers have a geometry and a disposition suited to maximize filling the cavity with the agent. 6. The device according to claim 1, wherein the containers have at least one of different dimensions and gas storage capacities. 7. The device according to claim 1, wherein at least one of the containers is placed outside the cavity, fastened on an upholding mounting on one of the cap and the cavity, and configured to connect to the cavity via an incoming duct. 8. The device according to claim 1, wherein the upholding mounting comprises an axial element fastened perpendicularly to the cap, and wherein anchoring elements of the containers are placed around the axial element. 9. The device according to claim 8, wherein a measurement sensor for measuring a filling level of the cavity with the agent, and wherein the measurement sensor is incorporated on a portion of the axial element. 10. The device according to claim 1, wherein one of the containers is one of a pressurized container of additional pressure and a safety container in case of failure of one of the other containers. 11. The device according to claim 1, wherein at least one of the containers is interchangeable by switching its exit with the exit of another of the containers. 12. The device according to claim 1, wherein the cavity comprises an inlet configured to fill the agent into the cavity. 13. The device according to claim 1, wherein exits of the containers are placed in an interstice between the cap and the agent. 14. The device according to claim 13, wherein the interstice comprises gas flux deflector means at the exits of the containers. 15. The device according to claim 1, wherein the port is a breakage element configured to break at a pre-calibrated pressure. 16. The device according to claim 1, wherein at least one of the containers in the cavity is placed in a deployment membrane. 17. The device according to claim 16, wherein the deployment membrane is kept away from the port by means of at least one point of fastening of the deployment membrane placed at a distance from the port. 18. The device according to claim 1, wherein the gas generator comprises several containers placed at least on one side of the cap, each container being of cylindrical shape with a rotational axis perpendicular to the cap, and wherein a total area of their cylindrical sections is smaller than the one of the cap. 19. The device according to claim 1, wherein the agent is one of an extinguishing agent and a cooling agent. 20. The device according to claim 1, wherein the first one of the containers releases the first propulsion gas when the first one of the containers is electrically triggered, and the second one of the containers releases the second propulsion gas when the second one of the containers is electrically triggered. 21. The device according to claim 1, wherein the exit of each one of the containers directly communicates with the cavity. 22. The device according to claim 1, wherein the one of the two containers is removeably placed in the cavity by the upholding mounting fastened on the cap.
