Patent ID: 8800672

Claim:
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; and a 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, and wherein 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.
