Abstract: A fire extinguisher including a body extending along a longitudinal axis and defining a storage chamber wherein a load of an extinguishing agent is present, and also a pressurizing chamber including a pyrotechnic gas generator, the pressurizing chamber being separated from the storage chamber by a perforated wall configured to put an outlet of the pyrotechnic gas generator into communication with the storage chamber, the perforated wall defining an end of the storage chamber, the extinguisher having a discharge channel configured to deliver the extinguishing agent to the outside of the extinguisher during actuation of the pyrotechnic gas generator, the discharge channel opening out into the storage chamber through an opening positioned at a distance from the perforated wall, as measured along the longitudinal axis of the body, that is less than or equal to half the length of the storage chamber.

Abstract: A pyrotechnic gas generator for driving an actuator includes a body defining a combustion chamber housing a main pyrotechnic charge, and an ignitor for initiating combustion of the main pyrotechnic charge. The pyrotechnic gas generator includes at least one delay chamber adapted to communicate with the combustion chamber via at least one inlet orifice, and the delay chamber is provided with at least one outlet orifice for passing gas out from the gas generator. The at least one outlet orifice is provided with a seal adapted to pass from a closed state to an open state when the pressure inside the delay chamber reaches a rupture limit pressure.

Abstract: A spray device (100) for spraying a liquid (L), the device comprises a tank (10) containing the liquid (L) for spraying, at least one liquid ejector member (20) in communication with said tank (10), and a pyrotechnic gas generator (30) for pressurizing the liquid inside said tank and propelling it under pressure out from said tank. According to the invention, in at least one mode of operation, the ejector member (20) is in communication with the gas generator (30) in such a manner as to enable it to be fed with the gas generated by said generator (30).

Abstract: A normally closed electric switch having a sliding assembly that is actuated to open the switch, e.g. by a pyrotechnic gas generator. Prior to actuation, a conductive portion of the sliding assembly (21) is in tight contact with two rings (13a, 14a) that are axially offset on the same axis, belonging respectively to two electrically conductive tabs (13, 14), and after the actuator has been triggered, the upstream tab (13) is separated from the conductive portion of the sliding assembly. According to the invention, sliding assembly comprises a tube split by a slot extending along its entire length, and the conductive portion of the sliding assembly is constituted by all or part of said split tube, the clamping force between the conductive portion and the primary electrically conductive tabs being provided by the resilience of the split tube.

Abstract: The main subject of the present invention is a solid pyrotechnic gas generator compound, the composition of which contains, expressed in weight percentages: from 60 to 70% of guanidine nitrate, from 26 to 33%, advantageously 26 to 30%, of potassium perchlorate, from 2.5 to 6% of at least one combustion modifier chosen from transition metal oxides, the precursors of such oxides and mixtures thereof, from 0 to 6% of at least one additive, and does not contain an explosive ingredient. Such a compound is particularly effective for the inflation of side airbags.

Abstract: The present invention concerns a composition for a pyrotechnic compound that can be used as a thermal fuse in a gas generator comprising a pyrotechnic charge, said pyrotechnic compound having a self-ignition temperature that is lower than that of the pyrotechnic charge of the generator so as to be capable of initiating combustion of the pyrotechnic charge in the event of abnormal heating of the generator before said pyrotechnic charge reaches its self-ignition temperature. This composition is characterized in that it can be metered out and deposited in the form of an adhesive onto any appropriate support of the generator.

Abstract: The present invention provides pyrotechnic gas generator compounds and a method of obtaining them. Said compounds have a composition which comprises: an oxidizing charge which comprises at least one inorganic perchlorate and which does not comprise a chlorine scavenger; and a crosslinked, oxygen-containing hydrocarbon binder obtained by crosslinking an elastomer in the presence of at least one crosslinking agent and at least one oxygen-containing plasticizer for said elastomer; said elastomer having a molecular weight of more than 200 000 and being preferably selected from polyesters and polyacrylates; said at least one oxygen-containing plasticizer being composed of a plasticizer of which the molecular weight is greater than 350 g/mol and the oxygen balance equal to or greater than ?230 %, of a mixture of such plasticizers with one another or of a mixture of at least one such plasticizer with at least one other oxygen-containing plasticizer.
