The invention relates to a fire extinguishing device for a special protection vehicle according to claim 1. Furthermore, the invention relates to a special protection vehicle with such a fire extinguishing device. EP 2543415 A1 discloses a fire extinguishing device comprising an extinguishing agent line for pressurized extinguishing agent, a detection agent line for pressurized detection agent, and an extinguishing agent line-detection agent line connecting line between the extinguishing agent line and the detection agent line. The object of the invention is to provide a fire extinguishing device for a special protection vehicle and a special protection vehicle, so that the special protection vehicle can be particularly advantageously protected from external attacks.This object is achieved according to the invention by a fire extinguishing device for a special protection vehicle having the features of patent claim 1 and by a special protection vehicle having the features of patent claim 10. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description. A first aspect of the invention relates to a fire extinguishing device for a special protection vehicle. The special protection vehicle is designed, for example, as a passenger car. Preferably, the special protection vehicle, particularly in its fully manufactured state, has the fire extinguishing device. The fire extinguishing device can be understood in particular as a fire extinguishing device to be integrated into the special protection vehicle or integrated into the special protection vehicle. The fire extinguishing device can in particular be referred to as a fire extinguishing system.23-2658 PIF 2 The term "special protection vehicle" can be understood, in particular, as a special protection vehicle. The special protection vehicle preferably has at least one integrated armor plating to protect the occupants or cargo of the special protection vehicle from external attacks. The special protection vehicle can therefore also be referred to as a security vehicle or an armored vehicle. The special protection vehicle is preferably protected or can be protected, in particular by means of the armor plating, from explosives, gunfire, and / or the like. The special protection vehicle preferably has at least one drive device by means of which the special protection vehicle can be driven. The drive device is designed, for example, as an internal combustion engine. The special protection vehicle can thus be designed, for example, as a special protection vehicle driven by an internal combustion engine.Alternatively or additionally, the drive device is designed as an electric machine. The special protection vehicle can thus be designed as an electrically driven special protection vehicle. This means that the special protection vehicle can be designed as a battery-electric vehicle or as a hybrid vehicle. The fire extinguishing device has at least one first storage device, which is designed, for example, as a container, which can in particular be referred to as the first container. At least one extinguishing fluid can be stored or accommodated in the first storage device as the first extinguishing agent. In other words, the first storage device is designed to store or accommodate the first extinguishing agent, which is an extinguishing fluid.The fire extinguishing device has at least one first line section, through which the first extinguishing agent can flow, and via which the first extinguishing agent, in particular at least a portion of the extinguishing agent stored in the first storage device, can be discharged from the first storage device. In other words, the first line section and the first storage device are fluidly connectable or connected to one another, at least indirectly, in particular directly. For example, a connection point is provided, via which at least a portion of the first extinguishing agent stored in the first storage device can be discharged from the first storage device and, in particular directly, introduced into the first line section.23-2658 PIF 3 The fire extinguishing device has at least one first outlet opening which opens into a receiving space of the special protection vehicle and is designed to accommodate at least one component of the special protection vehicle and through which the first extinguishing agent can flow. This means that the first outlet opening opens into the receiving space which is designed to accommodate or arrange the at least one component. In other words, the component of the special protection vehicle can be or is arranged in the receiving space. In particular, the outlet opening is fluidically connected, for example directly, to the receiving space. Via the first outlet opening, at least a portion of the first extinguishing agent, which is in particular discharged from the first storage device and introduced into the first line section, can be discharged from the first line section and can be introduced, in particular directly, into the receiving space.In other words, the first line section and the receiving space are fluidically connectable or connected to one another via the first outlet opening, in particular directly, whereby the first extinguishing agent can be supplied to the receiving space via the first outlet opening, in particular directly. This means that the receiving space can be at least partially, in particular predominantly or completely, flooded with the first extinguishing agent via the first outlet opening, for example in order to fight a fire in the receiving space. By introducing the first extinguishing agent into the receiving space via the first outlet opening, a fire in the receiving space, for example the burning component, can be extinguished. The component is, for example, a component of a drive train of the special armored vehicle. The component is, for example, the internal combustion engine or the electric machine.The receiving space is preferably designed as a front-side receiving space. The receiving space is particularly preferably designed as an engine compartment. The fire extinguishing device has at least one second storage device, which is designed in particular separately from the first storage device and is designed, for example, as a container which can in particular be referred to as a second container. At least one extinguishing powder can be stored or accommodated in the second storage device as a second extinguishing agent. In other words, the second storage device is designed to store or accommodate the second extinguishing agent, which is an extinguishing powder. The second extinguishing agent is an extinguishing agent different from the first extinguishing agent. 23-2658 PIF 4 The fire extinguishing device has at least one second line section, which is designed in particular separately from the first line section.The second line section is preferably designed to allow the second extinguishing agent to flow through it or to transport the second extinguishing agent. The second extinguishing agent, in particular at least a portion of the second extinguishing agent stored in the second storage device, can be discharged from the second storage device via the second line section. In other words, the second storage device and the second line section are fluidly connectable or connected to one another, in particular at least indirectly or directly. For example, a connection point is provided via which at least a portion of the second extinguishing agent stored in the second storage device can be discharged from the second storage device and, in particular directly, introduced into the second line section.The fire extinguishing device has at least one second outlet opening on an underside of the special protection vehicle, which opens into the environment of the special protection vehicle, in particular directly. In particular, the second outlet opening is fluidically connectable or connected to the environment. Preferably, the second extinguishing agent can flow through the second outlet opening or is designed to transport, i.e., to allow the second extinguishing agent to pass through. The underside can be understood, in particular, as an outer side of the special protection vehicle pointing downwards in the vertical direction of the vehicle. At least a portion of the second extinguishing agent, in particular drawn from the second storage device and introduced into the second line section, can be discharged from the second line section via the second outlet opening and can be introduced, for example, directly, into the environment, in particular in the vertical direction beneath the special protection vehicle.In other words, the second line section and the surroundings are fluidically connectable or connected to one another, in particular directly, via the second outlet opening. Thus, the second extinguishing agent can be supplied to the surroundings via the second outlet opening on the underside of the special armored vehicle, i.e., below the special armored vehicle in relation to the vehicle's vertical direction, in order to combat, in particular to extinguish, a fire, in particular in the vehicle's vertical direction below the special armored vehicle. This means that by introducing the second extinguishing agent into the surroundings via the second outlet opening, a fire can be extinguished in the vehicle's vertical direction below the special armored vehicle, i.e., for example, a burning object can be extinguished.The object can be understood, in particular, as an object designed separately from the 23-2658 PIF 5 special armored vehicle, which can be located below the special armored vehicle in the vertical direction of the vehicle. The introduction of the second extinguishing agent into the environment via the second outlet opening can be understood, in particular, as flooding a space extending between the special armored vehicle and a subsurface with the second extinguishing agent. The subsurface is, for example, a roadway for the special armored vehicle. The first storage device, the first line section, and the first outlet opening are, for example, part of a first extinguishing system of the fire extinguishing device.The second storage device, the second line section and the second outlet opening are, for example, part of a second extinguishing system of the fire extinguishing device, which is in particular different from the first extinguishing system, for example designed separately from the first extinguishing system. The first extinguishing system is preferably designed to extinguish the receiving space. The second extinguishing system is preferably designed to extinguish the ground below, and in particular objects located vertically below the special armored vehicle and, for example, arranged on the ground below. The fire extinguishing device can therefore be a multi-part, in particular two-part, system. The invention is based in particular on the following findings and considerations: By means of the extinguishing device according to the invention, both a fire in the receiving space and a fire below the special armored vehicle can be extinguished.This can significantly improve fire protection of the special armored vehicle, whereby the special armored vehicle can be particularly well protected against external attacks. This means that the security of the special armored vehicle against external attacks can be significantly increased. Using the extinguishing device according to the invention, the special armored vehicle can be protected against fire attacks, particularly in the underbody area. In principle, it is conceivable to extinguish fires in the accommodation compartment and fires beneath the special armored vehicle, particularly on the roadway, with the same extinguishing agent. In contrast, the extinguishing device according to the invention uses different extinguishing agents in the form of extinguishing fluid and extinguishing powder. The extinguishing powder can extinguish fires beneath the special armored vehicle, particularly on the roadway, particularly effectively.By introducing the extinguishing fluid into the receiving space, damage to the component(s) of the special protection vehicle can be avoided, although such damage can occur with extinguishing powder. Furthermore, for example in the event of a false alarm or incorrect activation of the fire extinguishing device, the extinguishing fluid can be removed from the receiving space with particularly little effort, for example by itself. This removal can be significantly less effort than any removal of extinguishing powder from the receiving space. By means of the extinguishing device according to the invention, unwanted interaction between extinguishing agent and components arranged in the receiving space can be avoided and / or the negative effects of a false alarm or incorrect activation of the fire extinguishing device can be kept to a minimum.The extinguishing fluid is, for example, an extinguishing liquid and / or an extinguishing gas. For example, the extinguishing fluid is carbon dioxide (CO2). The extinguishing fluid is, or can be stored, in the first storage device, in particular under pressure, in the gaseous state. For example, when introduced into the receiving space via the first outlet opening, the extinguishing fluid is at least partially in the liquid state, whereby the extinguishing fluid can be referred to in particular as a liquid extinguishing agent. The extinguishing powder is, for example, extinguishing sand, which can also simply be referred to as sand. Overall, it can be seen that the extinguishing device according to the invention can be used to create a fire extinguishing system with liquid extinguishing agent and with extinguishing powder for the special armored vehicle.In a further embodiment, it is provided that the first line section has at least one first line section formed from a rigid material and at least one second line section formed from a flexible material, in particular different from the first line section, which second line section is fluidly connected or connectable, in particular at least indirectly or directly, to the first line section. In other words, at least one first wall, which at least partially, in particular predominantly or completely, delimits the first line section, is formed from the rigid material, and at least one second wall, which at least partially, in particular predominantly or completely, delimits the second line section, is formed from the flexible material.As a result, manufacturing inaccuracies in the fire extinguishing device, for example in the first line section, and / or inaccuracies during installation of the fire extinguishing device in the special protection vehicle can be compensated for in a particularly low-cost manner using the flexible 23-2658 PIF 7 material of the second line section. In other words, the flexible material can compensate for manufacturing tolerances in the fire extinguishing device, for example in the first line section, particularly advantageously, in particular with particularly low cost and / or with particular precision. By compensating for the manufacturing inaccuracies or tolerances, the manufacturing costs of the fire extinguishing device, in particular of the special protection vehicle, can be kept particularly low. Thus, a respective rigid extinguishing agent line can be replaced with a respective flexible extinguishing agent line.The fact that the line sections are fluidically connected to one another can be understood in particular to mean that the first extinguishing agent can be discharged from the first line section and, in particular, at least indirectly or directly, introduced into the second line section and / or that the first extinguishing agent can be discharged from the second line section and, in particular, indirectly or directly, introduced into the first line section. The flexible material can be understood in particular to mean an elastic or stretchable and / or soft material. Preferably, the more flexible material is more flexible, i.e. more elastic, than the rigid material. This means that when a force is applied to the respective line section or the respective wall, the resulting expansion of the respective line section or the respective wall is greater with the flexible material than with the rigid material.The respective line section can be understood, in particular, to mean a respective line element of the first line section. In a further embodiment, it is provided that the first line section opens into the receiving space via the first outlet opening, in particular directly. In other words, the first outlet opening is arranged on the first wall or on the first line element, in particular directly. Rigid material can therefore be used to introduce the first extinguishing agent into the receiving space. This makes it possible to keep the manufacturing costs of the fire extinguishing device particularly low. Alternatively or additionally, a particularly precise introduction of the first extinguishing agent into the receiving space can be enabled.In a further embodiment, it is provided that the first line section is arranged downstream of the second 23-2658 PIF 8 line section, in particular in the flow direction of the first extinguishing agent flowing through the first line section or the line sections. This means that the first extinguishing agent can be discharged from the second line section, in particular via a connection point of the first line section arranged between the line sections, and can be introduced into the first line section, in particular at least indirectly or directly. The second line section can thus be used as a connecting section for connecting, in particular fluidically, the first storage device to the first line section. As a result, the manufacturing tolerances or manufacturing inaccuracies can be compensated for particularly advantageously, in particular with particularly little effort and / or with particular precision.In a further embodiment, it is provided that the second line section has at least one first longitudinal region formed from a rigid material and at least one second longitudinal region formed from a flexible material, in particular different from the first longitudinal region, which second longitudinal region is or can be fluidly connected, in particular at least indirectly or directly, to the first longitudinal region. In other words, at least one third wall, which at least partially, in particular predominantly or completely, delimits the first longitudinal region, is formed from the rigid material, and at least one fourth wall, which at least partially, in particular predominantly or completely, delimits the second longitudinal region, is formed from the flexible material.This allows the manufacturing tolerances of the fire extinguishing device, for example, in the first length range, and / or the inaccuracies during installation of the fire extinguishing device in the special armored vehicle to be compensated for in a particularly low-cost manner. In other words, the manufacturing tolerances of the fire extinguishing device, for example, in the first length range, can be compensated for particularly advantageously, in particular with particularly low cost and / or with particular precision, using the flexible material. By compensating for the manufacturing inaccuracies or tolerances, the manufacturing costs of the fire extinguishing device, in particular of the special armored vehicle, can be kept particularly low.The fact that the length regions are fluidically connected to one another can be understood in particular to mean that the second extinguishing agent can be discharged from the first length region and in particular at least indirectly or directly introduced into the second length region and / or that the second extinguishing agent can be discharged from the second length region and in particular at least indirectly or directly introduced into the first length region. The respective length region can be understood in particular to mean a respective line element of the second line section. The first line section and the first length region can be formed from identical or different, in particular rigid, materials. The second line section and the second length region can be formed from identical or different, in particular flexible, materials.In a further embodiment, it is provided that the first longitudinal region opens into the environment via the second outlet opening, in particular directly. In other words, the second outlet opening is arranged, in particular directly, on the third wall or on the first line element of the second line section. As a result, the rigid material can be used to introduce the second extinguishing agent into the environment. As a result, the manufacturing outlay for the fire extinguishing device can be kept particularly low. Alternatively or additionally, the second extinguishing agent can be introduced into the environment particularly safely and / or particularly precisely. In a further embodiment, it is provided that the first longitudinal region is arranged downstream of the second longitudinal region, in particular in the flow direction of the second extinguishing agent flowing through the second line section or the longitudinal regions.This means that the second extinguishing agent can be discharged from the first length region, for example via a connection point arranged between the length regions, and can be introduced, in particular at least indirectly or directly, into the second length region. As a result, the second length region formed from the flexible material can be used as a connecting section for connecting, in particular fluidically, the second storage device to the first length region. As a result, the manufacturing tolerances can be compensated for particularly advantageously, in particular with particularly little effort and / or with particular precision. The direction of flow can be understood in particular as a transport direction of the second extinguishing agent during transport through the second line section or through the length regions.In a further embodiment, it is provided that the flexible material, in particular of the second line section and / or the second length region, is a plastic, in particular a respective plastic. This means that the second line section, in particular the second wall, and / or the second length region, in particular the fourth wall, is made of plastic. This ensures the flexibility of the flexible material in a particularly low-cost manner, whereby the manufacturing costs of the fire extinguishing device can be kept particularly low. Furthermore, the plastic can be particularly lightweight. The plastic is, for example, ethylene propylene diene rubber (EPDM).Particularly when the fire extinguishing system, in its installation position within the special armored vehicle, extends over a particularly large area within the special armored vehicle, a particularly large number of manufacturing tolerances of various components of the special armored vehicle can affect the fire extinguishing system. This means that a particularly large number of vehicle tolerances can occur in the fire extinguishing system. By using the flexible material, the vehicle tolerances can be compensated for particularly inexpensively and / or with particular precision. In contrast, this may not be possible with a conventional fire extinguishing system with, in particular exclusively, rigid extinguishing agent lines, especially in the underbody.In a further embodiment, the fire extinguishing device comprises at least one sensor device, by means of which at least one fire in the armored vehicle, in particular in the receiving compartment, and / or in the surroundings of the armored vehicle, in particular vertically beneath the armored vehicle, can be or is detected. In other words, the fire can be detected, in particular automatically, by means of the sensor device.It is preferably provided that the fire extinguishing device has at least one electronic computing device, by means of which a valve device assigned to the first line section and / or the first storage device can be or is controlled as a function of the fire detected, in particular by means of the sensor device, in order to introduce at least a portion of the first extinguishing agent via the first outlet opening, in particular directly, into the receiving space. In other words, the sensor device and the electronic computing device are coupled to one another in such a way that, in particular by controlling the valve device, the first extinguishing agent is introduced into the receiving space when the fire is detected, in particular in the receiving space, by means of the sensor device. The valve device can in particular be referred to as the first valve device.23-2658 PIF 11 Alternatively or additionally, it is provided, for example, that a valve device, in particular different from the first valve device, which is assigned to the second line section and / or the second storage device and can be referred to in particular as a second valve device, can be or will be controlled by means of the electronic computing device as a function of the fire detected in particular by means of the sensor device, in order to introduce at least part of the second extinguishing agent via the second outlet opening, in particular directly, into the environment. In other words, the sensor device and the electronic computing device are coupled to one another in such a way that, in particular by controlling the second valve device, the second extinguishing agent is introduced into the environment when the fire is detected by means of the sensor device, in particular in the environment.By means of the sensor device, in particular by controlling the respective valve device for introducing the respective extinguishing agent, the respective fire can be automatically detected and the respective fire can be automatically extinguished. As a result, the fire protection of the special protection vehicle, also referred to as fire protection, can be particularly enhanced by means of the fire extinguishing device. Preferably, the fire extinguishing device has the first and / or the second valve device. Preferably, a mass flow of the first extinguishing agent flowing through the first line section and / or discharged from the first storage device and introduced into the first line section can be adjusted by means of the first valve device.Preferably, a mass flow of the second extinguishing agent flowing through the second line section and / or discharged from the second storage device and introduced into the second line section can be adjusted by means of the second valve device. A second aspect of the invention relates to a special protection vehicle which has at least one fire extinguishing device according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa. A further aspect relates to a method for operating a fire extinguishing device according to the first aspect of the invention. Advantages and advantageous embodiments of the 23-2658 PIF 12 first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the further aspect and vice versa.Further features of the invention emerge from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respective combination specified, but also in other combinations or on their own. The invention will now be explained in more detail using a preferred embodiment and with reference to the drawings. There shows: Fig. 1 a schematic partial sectional view of a special protection vehicle according to the invention with a fire extinguishing device according to the invention; and Fig. 2 a schematic and perspective partial view of a fire extinguishing device according to the invention. In the figures, identical or functionally equivalent elements are provided with the same reference numerals. Fig.1 shows a schematic side partial sectional view of a special protection vehicle 1. Thus, in particular, a side view of the special protection vehicle 1 is shown in Fig. 1. The special protection vehicle 1 preferably has a, in particular self-supporting, body 2. For example, the body 2 delimits an interior 3 at least partially, in particular predominantly and completely, for example at least indirectly or directly. The special protection vehicle 1 has at least one receiving space 4, for example at the front, which is preferably designed as an engine compartment 5. In the exemplary embodiment, at least one component 6 of the special protection vehicle 1 is arranged or received in the receiving space 4. The 23-2658 PIF 13 component 6 is, for example, a drive device 7, which is designed, for example, as an internal combustion engine or as an electric machine.The special protection vehicle 1 can preferably be driven by means of the drive device 7. The special protection vehicle 1 has at least one fire extinguishing device 8, which is shown in Fig. 2 in a schematic and perspective partial view. In order to be able to particularly increase security against external attacks of the special protection vehicle 1, it is provided that the fire extinguishing device 8 has at least one first storage device 9, in which at least one extinguishing fluid can be stored or is stored as the first extinguishing agent. The first extinguishing agent is, for example, carbon dioxide (CO2). The first storage device 9 is, for example, designed to be replaceable. This means that the first storage device 9 is designed, for example, as an exchangeable container, in particular as a cartridge.Furthermore, the fire extinguishing device 8 has at least one first line section 10, via which the first extinguishing agent can be discharged from the first storage device 9 and introduced into the first line section 10. The fire extinguishing device 8, in particular the first line section 10, also has at least one first outlet opening 11 opening into the receiving space 4, in particular into the engine compartment 5. In the exemplary embodiment, a plurality of first outlet openings 11 opening into the receiving space 4, in particular directly, are provided, which are preferably spaced apart from one another. At least a portion of the first extinguishing agent can be discharged from the first line section 10 via the respective outlet opening 11 and introduced, in particular directly, into the receiving space 4, in particular for extinguishing the component 6.Thus, for example, the first extinguishing agent is discharged from the first storage device 9 via the first line section 10 and introduced into the first line section 10, whereby the first extinguishing agent flows through the first line section 10. The first extinguishing agent flowing through the first line section 10 is introduced into the receiving space 4 via the respective first outlet opening 11. In order to be able to particularly increase the security of the special protection vehicle 1 against external attacks, it is provided that the fire extinguishing device 8 has at least one second storage device 12 in which at least one extinguishing powder can be stored or is stored as the second extinguishing agent. The second storage device 12 is designed, for example, to be replaceable. This means that the second storage device 12 is designed, for example, as an exchangeable container, 23-2658 PIF 14 in particular as a cartridge.Furthermore, the fire extinguishing device 8 has at least one second line section 13, via which the second extinguishing agent can be discharged from the second storage device 12 and, in particular, at least indirectly or directly, introduced into the second line section 13. In addition, the fire extinguishing device 8 has at least one second outlet opening 16 on an underside 14 of the special protection vehicle 1, which opens into an environment 15 of the special protection vehicle 1. In the exemplary embodiment, a plurality of second outlet openings 16 are provided on the underside 14, which open into the environment, in particular directly, and which are preferably spaced apart from one another. The respective second outlet opening 16 is preferably arranged in the vertical direction 17 of the special protection vehicle 1 under a floor element 18 of the body 2, wherein the floor element 18 is designed, for example, as the main floor of the body 2.For example, the floor element 18 delimits the interior space 3 downwards in the vehicle's vertical direction 17. At least a portion of the second extinguishing agent can be discharged from the second line section 13 via the respective second outlet opening 16 and introduced, in particular in the vehicle's vertical direction 17 beneath the special armored vehicle 1, preferably directly, into the environment 15. As a result, the second extinguishing agent can be introduced via the respective second outlet opening 16 into a space 20 extending between the special armored vehicle 1, in particular a floor of the special armored vehicle 1, and a roadway 19, in order to extinguish, for example, at least one burning object arranged on the roadway 19 beneath the special armored vehicle 1 in the vehicle's vertical direction 17. The second extinguishing agent, which can be sand, for example, can thus be distributed over the roadway 19.Thus, for example, the second extinguishing agent is discharged from the second storage device 12 via the second line section 10 and introduced into the second line section 13, whereby the second extinguishing agent flows through the second line section 13. The second extinguishing agent flowing through the second line section 13 is introduced into the environment 15 via the respective second outlet opening 16. The extinguishing powder can be used to extinguish a fire in the vertical direction 17 beneath the special armored vehicle 1 particularly effectively. By using the extinguishing fluid for the receiving space 4, filling the receiving space 4 with extinguishing powder can be avoided. This means that the particularly laborious removal of extinguishing powder from the receiving space 4, for example in the event of a false activation of the fire extinguishing device 8, can be avoided. Furthermore, a fire in the receiving space 4 can be extinguished particularly effectively using the extinguishing fluid.23-2658 PIF 15 Overall, it can be seen that by means of the fire extinguishing device 8, at least two different extinguishing agents, such as liquid CO2 for the receiving space 4 and extinguishing powder for an underbody area or for the roadway 19, can be integrated into the special protection vehicle 1, whereby the special protection vehicle 1 can be particularly well protected against external attacks, in particular fire attacks, in a particularly advantageous manner. In the exemplary embodiment, it is provided that the first line section 10 has at least one first line section 22 formed from a rigid material 21 and at least one second line section 24 formed from a flexible material 23, which is or can be fluidically connected, in particular at least indirectly directly, to the first line section 22.The first line section 22 can have one line element or a plurality of line elements, in particular formed separately from one another. In the exemplary embodiment, the first line section 22 has a first line element 25, through which the first extinguishing agent can flow. The second line section 24 in the exemplary embodiment is a second line element 26. The line elements 25, 26 are fluidically connected to one another, for example directly, via a first connection point 27. The flexible material 23 is, for example, a plastic, preferably EPDM. In the exemplary embodiment, the first line section 22 is arranged downstream of the second line section 24. This means that the first line element 25 is arranged downstream of the second line element 26.In the exemplary embodiment, the fire extinguishing device 8 has at least one third line element 28, through which the first extinguishing agent can flow, which is fluidically connected, in particular directly, to the second line element 26 via a second connection point 29 and fluidically connected, in particular directly, to the first storage device 9 via a third connection point 30. The third line element 28 is arranged downstream of the first storage device 9 and upstream of the second line element 26. The third line element 28 is formed, for example, from the rigid material 21. At least a portion of the first extinguishing agent stored in the first storage device 9 can be discharged from the first storage device 9 via the third connection point 30 and introduced, in particular directly, into the first line section 10, in particular into the third line element 28.23-2658 PIF 16 In the exemplary embodiment, it is provided that the first line section 22 opens into the receiving space 4 via the respective first outlet opening 11, in particular directly. This means that the respective first outlet opening 11 is arranged, in particular directly, on the first line element 25. Because the second line section 24, in particular the second line element 26, is formed from the flexible material 23, tolerances of the fire extinguishing device 8, in particular for connecting the first line element 25 to the first storage device 9, in particular to the third line element 28, can be kept particularly low by, in particular, elastic deformation of the flexible material 23.In the exemplary embodiment, it is provided that the second line section 13 has at least one first longitudinal region 31 formed from the rigid material 21 and at least one second longitudinal region 32 formed from the flexible material 23. The first longitudinal region 31 can have one line element or several line elements. In the exemplary embodiment, the first longitudinal region 31 has two line elements 33, 34, namely a fourth line element 33 and a fifth line element 34. The second extinguishing agent can preferably flow through the line elements 33, 34. The second longitudinal region 32 has, for example, a sixth line element 35, through which the second extinguishing agent can flow. In a further embodiment, it is provided that the first longitudinal region 31 opens into the environment 15 via the respective second outlet opening 16, in particular directly.This means that the respective second outlet opening 16 is arranged, in particular directly, on the line elements 33, 34, in particular on one of the line elements 33, 34 in each case. In a further embodiment, it is provided that the first longitudinal region 31 is arranged downstream of the second longitudinal region 32. As shown in Fig. 2, it is provided, for example, that the sixth line element 53 is fluidically connected to the line elements 33, 34 at a fourth connection point 36, in particular directly. The second extinguishing agent can preferably be divided between the fourth and fifth line elements 33, 34 at the fourth connection point 36.

Detection can be carried out, for example, by means of temperature detection and / or by means of smoke detection. Temperature detection can be understood, for example, as the detection of at least one temperature increase, in particular caused by the fire. In a further embodiment, the fire extinguishing device 8 has at least one electronic computing device 43, which is coupled or can be coupled, in particular, to the sensor device 40. For example, the fire extinguishing device 8 has at least one first valve device 44 assigned to the first line section 10.The first valve device 44 can be arranged, in particular directly, in the first line section 10, or the first valve device 44 can be arranged, in particular directly, in the first storage device 9. For example, the first valve device 44 can be controlled by means of the electronic computing device 43 as a function of the fire detected, in particular by means of the first sensor element 41, in order to introduce at least a portion of the extinguishing agent stored, in particular, in the first storage device 9, in particular via the first line section 10, into the receiving space 4 via the respective first outlet opening 11. Alternatively or additionally, the fire extinguishing device 8 has at least one second valve device 45, which is designed, in particular, separately from the first valve device 44 and is assigned to the second line section 13.The second valve device 45 can be arranged, in particular directly, in the second line section 13, or the second valve device 45 can be arranged, in particular directly, in the second storage device 12. The second valve device 45 can thus be understood to mean, in particular, a valve device 45 assigned to the second storage device 12. For example, the second valve device 45 can be controlled by the electronic computing device 43 as a function of the fire detected, in particular by the second sensor element 42, in order to introduce at least a portion of the second extinguishing agent, stored in particular in the second storage device 12, into the environment 15 via the respective second outlet opening 16, in particular via the second line section 13. 23-2658 PIF 19 Numeralia, such as "first," "second," "third," etc., are intended solely for differentiation and do not indicate any order.
