Definitions
- the invention relates to a fire extinguisher comprising a pyrotechnic gas generator.
- a fire extinguisher is conventionally in the form of a tank comprising an extinguishing agent which is intended to be delivered to the zone of a fire in order to extinguish it.
- extinguishers are known from the state of the art.
- the permanent pressurized fire extinguishers comprise a gas pressure tank containing the extinguishing agent or a pressurized gas cylinder in communication with the chamber in which the extinguishing agent is present.
- this type of extinguisher there is therefore permanent storage under pressure of the extinguishing agent or the propellant of the extinguishing agent.
- the gas cylinder is first actuated by the user in order to release the pressurizing gas into the chamber comprising the extinguishing agent and then the agent. extinguishing thus pressurized is delivered to the fire zone by manual actuation.
- Extinguishers with permanent pressurization have certain disadvantages, in particular the fact of requiring a certain number of monitoring and verification operations (periodic weighing).
- the pressure of the gas varies with the temperature, the operation of this type of extinguishers is sensitive to the temperature.
- Another drawback is that, during the delivery of the extinguishing agent, the volume available for the gas increases and therefore the pressure of the gas decreases, which results in a reduction in the rate of delivery of the extinguishing agent. and, therefore, a decrease in the effectiveness of the fire extinguisher.
- a second type of extinguisher including a pyrotechnic gas generator.
- the pyrotechnic gas generator makes it possible to produce a combustion gas which pressurizes the chamber in which the extinguishing agent is present and, consequently, the delivery of the extinguishing agent to the fire zone.
- These fire extinguishers with pyrotechnic gas generator are relatively powerful and can overcome some of the disadvantages of fire extinguishers permanent pressurization.
- an extinguisher comprising a pyrotechnic gas generator having an architecture relatively close to the permanent pressurizing extinguishers using a pressurized gas cylinder.
- the gas generator is actuated by a manual striker located at one end of the tank and communicates with the loading of the extinguishing agent via a first dip tube.
- a second plunger tube is connected to the outlet port and provides delivery of the extinguishing agent to the outlet port.
- a lance equipped with a trigger communicates with the outlet orifice and allows the extinguishing agent to be delivered into the external medium following actuation by a user.
- the extinguisher of the document DE202006002892 has certain advantages but has however a structure that it would be desirable to be able to simplify in particular to reduce the cost of manufacturing such extinguisher. Furthermore, the delivery rate of the extinguishing agent is not always optimal in this type of extinguisher.
- Document is also known RU 2 085 235 C1 a simplified fire extinguisher comprising a pyrotechnic gas generator.
- a fire extinguisher comprising a body extending along a longitudinal axis and defining a storage chamber in which a loading of an extinguishing agent is present and a pressurizing chamber comprising a pyrotechnic gas generator, the pressurizing chamber being separated from the storage chamber by a perforated wall configured to put in communication an output of the pyrotechnic gas generator with the chamber of storage, the perforated wall defining a bottom of the storage chamber, the extinguisher comprising a discharge channel configured to deliver the extinguishing agent outside the extinguisher during the actuation of the pyrotechnic gas generator , said evacuation channel opening into the storage chamber through an opening positioned at a distance from the perforated wall, measured along the longitudinal axis of the body, less than or equal to half the length of the storage chamber.
- the pyrotechnic gas generator is configured to produce combustion gas flowing to the storage chamber through the outlet of said gas generator and the perforated wall to pressurize the storage chamber.
- the evacuation channel is, in turn, configured to allow the delivery of extinguishing agent in the environment outside the extinguisher following the pressurization of the storage chamber by the combustion gas.
- the extinguisher according to the present invention has a particular arrangement in which there is on the one hand separation between the compartment comprising the gas generator and the compartment comprising the extinguishing agent and on the other hand positioning of the evacuation channel relatively close to the bottom of the storage chamber.
- This particular arrangement advantageously allows to have a powerful fire extinguisher allowing the delivery of the majority or substantially all of the mass of the loading of the extinguishing agent while having a simplified structure in which the implementation of dip tubes in the storage chamber is rendered superfluous.
- the invention provides an effective extinguisher having a manufacturing cost significantly reduced compared with the extinguishers described in DE202006002892 .
- the fire extinguisher may further comprise a first shutter sealing the discharge channel, said first shutter being configured to allow the exit of the extinguishing agent outside the fire extinguisher through the discharge channel when the pressure in the storage chamber exceeds a predefined value.
- the delivery rate of the extinguishing agent may not always be optimal when an extinguisher as taught in the document DE202006002892 is implemented.
- the inventors have found that the problem that can be encountered by a fire extinguisher of this type using manual actuation is that, at the moment when the user actuates the opening of the outlet orifice, the pressure inside the reservoir may have significantly decreased. Indeed, the gases generated by a pyrotechnic gas generator are hot and the pressurizing effect of the tank is therefore more temporary, because of the cooling of the gases, than that provided by a gas cartridge generating cold gases.
- the above configuration implementing the first shutter advantageously makes it possible to optimize the flow rate of extinguishing agent delivered by the extinguisher since, as soon as a predetermined pressure threshold is reached in the storage chamber, the first shutter automatically allows (ie without requiring actuation by a user) the delivery of extinguishing agent outside the fire extinguisher.
- Such a configuration advantageously makes it possible to best use the overpressure generated by the gas generator to distribute the extinguishing agent and avoids the problem of actuation by a user that can be carried out at a time when the overpressure in the reservoir has already significantly decreased.

- the distance between the opening and the perforated wall may be less than or equal to one quarter of the length of the storage chamber.

- the diameter of the storage chamber corresponds to the largest transverse dimension of the storage chamber.
