Patent ID: 8499560

Claim:
A method for the autonomous injection of a fluid, comprising: thermal initiation and combustion of at least one thermally initiatable gas-generating pyrotechnic charge; generation of combustion gases, said gases consisting of those resulting from said combustion of said at least one thermally initiatable gas-generating pyrotechnic charge or consisting of those resulting from said combustion of said at least one thermally initiatable gas-generating pyrotechnic charge and the combustion of at least one combustion-initiated pyrotechnic charge combustion-initiated by said at least one thermally initiatable pyrotechnic charge; pressurization of said fluid under action of said combustion gases; and delivery of said pressurized fluid; said fluid being a safeguarding, protective or conditional preventive-maintenance fluid delivered into a system subject to overheating; and said combustion of said at least one thermally initiatable pyrotechnic charge being carried out in at least one housing of suitable thermal conductivity, said at least one housing being in contact with and heated by said system subject to overheating or being at least partially integrated into said system.
