    An embodiment of a tank device designated as a whole as 100 in FIGS. 1 to 8 comprises several, for example 15, tank elements 102, which each comprise an inner space 104 for receiving a fluid, in particular a gas. 10/31 «t ························································································· - 11 * - ... ..
    The tank elements 102 each include two substantially identical hollow cylindrical sections 106 and two substantially identical end caps 108 and a connecting section 110.
    The connecting portion 110 is disposed between the hollow cylindrical portions 106.
    The end caps 108 are disposed at ends of the hollow cylindrical portions 106 which are disposed facing away from the connecting portion 110.
    The connecting section 110 of each tank element 102 is arranged in particular centrally on the tank element 102.
    Indentations 112 of the tank elements 102 are formed by means of the connecting sections 110, so that an inner cross-sectional area in the region of the connecting section 110 is minimized.
    In the region of the minimum inner cross-sectional area of the connecting portion 110, a plurality of passage openings 114 are formed, through which the inner space 104 of the tank elements 102 is accessible.
    As can be seen in particular from FIG. 5, the hollow-cylindrical sections 106 and the connecting sections 110 are components which are different from one another and which are connected to each other in a fluid-tight manner, for example by welding.
    By means of the hollow cylindrical sections 106, the end caps 108 and the connecting section 110 of each tank element 102, a continuous inner space 104 of the tank element 102 is formed, which is accessible only through the passage openings 114 in the connecting section 110. 11/31 • ··· ····· · · · ·
    As can be seen in particular from FIGS. 4 and 5, a plurality of tank elements 102 of the tank device 100 are connected to one another in a fluid-efficient manner by means of connecting elements 116. By means of seals 118 it is ensured that fluid disposed in the interior spaces 104 of the tank elements 102 does not undesirably escape into the environment.
    The connecting elements 116 can in particular be connected to the connecting sections 110 of the tank elements 102 by means of a plug connection. Alternatively or additionally, screw connections and / or snap-on connections can be provided.
    The tank elements 102, which are connected to one another in a fluid-efficient manner by means of the connecting elements 116, are preferably additionally mechanically connected to one another by wrapping by means of a winding device (not shown).
    Furthermore, a pouring or spraying of a plate 120 onto the connecting elements 116 and / or the connecting sections 110 can take place in order to achieve additional stabilization. The plate 120 then extends in particular along a connecting plane 122 of the tank device 100, along which the fluid connection between the individual tank elements 102 takes place by means of the connecting elements 116.
    The connecting elements 116 preferably include spacers 124, by means of which a predetermined distance between adjacently arranged tank elements 102 can be produced.
    Preferably, the tank elements 102 are not directly adjacent to one another in the region of the hollow cylindrical sections 106. Rather, fiber channels 126 are preferably formed between the tank elements 102, so that the tank elements 102 can serve as winding elements 128 of a winding core 130 and can be wrapped with one or more fibers for additional stabilization of the entire tank device 100. 12/31 - 13 - • · • · • ·
    The tank device 100 described above is manufactured as follows:
    The end caps 108, the hollow cylindrical portions 106, and the connecting portion 110 of each tank member 102 are preferably independent components which are manufactured independently.
    In particular, a fluid-tight inner shell 132 of each hollow cylindrical section 106 is manufactured independently of a connecting section 110.
    The end caps 108, the inner shells 132 of the hollow-cylindrical portions 106, and the connecting portions 110 are preferably welded together to fluid-tightly surround the inner space 104 of the tank member 102.
    In a next step, the tank element 102 thus obtained is provided in particular with a fiber reinforcement. Here, in particular, an outer shell 134 of the hollow cylindrical sections 106 is produced, by means of which the mechanical stability of the tank elements 102 is ensured. In particular, by means of the outer shell 134 of each hollow-cylindrical section 106, the pressure occurring in the filled state of the tank element 102 can be absorbed.
    A plurality of tank elements 102 produced in this way are then arranged parallel to one another with respect to a central axis 135 of the hollow cylindrical sections 106 and connected to one another by means of the connecting elements 116.
    In this case, the connecting elements 116 are in particular inserted into the passage openings 114 of the connecting sections 110 of two adjacent tank elements 102, in particular inserted. 13/31 - 14 - • · • ·
    As soon as the desired number of tank elements 102 are connected to one another by means of the connecting elements 116, the tank elements 102 are firmly connected to one another, for example, by pouring the plate 120 in the region of the connecting sections 110.
    The plate 120 is formed in particular by a material which hardens and thus enables a stable connection of the tank elements 102 in the region of the connecting sections 110.
    In a next step, the hollow cylindrical portions 106 of the tank elements 102 are wrapped by means of a winding device with one or more fibers. The first individual tank elements 102, which are initially connected to one another only via the connecting sections 110, are thereby connected to form an overall structure.
    The wrapping of the tank elements 102 takes place in particular in an endless winding process.
    After wrapping the tank elements 102 with the one or more fibers, they are infiltrated with a hardening matrix material, so that in particular the gaps forming the fiber channels 126 between the tank elements 102 are filled up and thus a continuous stable tank device 100 is available.
    An alternative embodiment of a tank device 100 shown in FIGS. 9 to 12 essentially differs from the embodiment illustrated in FIGS. 1 to 8 by an alternative embodiment of the connection sections 110.
    The connecting sections 110 according to the embodiment of the tank device 100 shown in FIGS. 9 to 12 have, instead of indentations 112, material reinforcements 136, which in particular in the interior 14/31 * ··· ····· * • · · · . The outer contour of the hollow cylindrical sections 106 is thereby continued substantially unchanged in the region of the connecting sections 110.
    Due to the material reinforcement 136, a section is also formed with a small internal cross-sectional area, in which the passage openings 114 open.
    A sealing receptacle 138 embodied as an annular groove is used in the embodiment of the tank device 100 shown in FIGS. 9 to 12 for receiving the seal 118.
    Incidentally, the alternative embodiment of the tank device 100 shown in FIGS. 9 to 12 is identical in construction and function to the embodiment shown in FIGS. 1 to 8, so that reference is made to the above description thereof. 15/31 * · · · ·········································································································································································
