in fig1 a to 2 b , schematic illustrations of various pressurized storage tank arrangements in accordance with embodiments are illustrated . the pressurized storage tank arrangement 10 includes cylindrical pressurized storage tanks 11 , which are permanently connected at both ends thereof to connecting elements of a connecting device 31 . the pressurized fluid flows out of the pressurized storage tanks 11 through bores 32 in the connecting elements . the connecting device 31 is of mechanically stable design and is connected at fastening points 41 , 42 in such a way as to be suspended or to stand , e . g ., in a vehicle . the pressurized storage tanks 11 are configured for connection to the connecting device 31 by way of screwed joints 50 . a temperature - controlled pressure reducer 21 , an automatic cylinder valve 23 and a maintenance valve 24 are integrated into or onto the connecting device 31 , as are valve blocks 12 , 22 . valves , valve blocks and the like may be mounted at any point in or on the connecting device 31 . moreover , reductions in cross section 37 are arranged in the connecting device 31 . selective routing of the flow circulation in the overall system is possible through the arrangement of the cited components as desired in the connecting device and through the free communication between the pressurized storage tanks 11 via the connecting device 31 . through the arrangement as desired of the filling valve unit 33 and of the removal valve unit 34 in the pressurized storage tank arrangement 10 , in particular , simple purging of the overall system during commissioning is thus made possible . a mechanically strong connection between the pressurized storage tanks 11 and the connecting device 31 is accomplished by way of a screwed joint 50 , for example , and is illustrated in detail in fig3 . fig3 is a schematic illustration of a connection between pressurized storage tanks 11 and connecting device 31 . for connection , use is made of a banjo bolt 51 , which is secured on the pressurized storage tank 11 by way of an external thread 52 . the internal thread 53 of the banjo bolt 51 is used to accommodate valves and / or filters that are close to the cylinder . other types of fastening are also possible , however . thus , the valves and / or filters close to the cylinder may be fixed using grooves 54 in the banjo bolt 51 by way of a retaining ring , for example . fig4 to 7 are schematic illustrations of further embodiments of the connection between the pressurized storage tank and the connecting device from the front . in fig4 , the connection between the pressurized storage tank 11 or a connecting section of the pressurized storage tank 11 and the connecting device 31 or a connection block of the connecting device 31 is embodied as a clamp joint or plug - in joint . clamping is accomplished by way of a clamp connecting element 122 , which is embodied as a crescent - shaped retaining ring and which is fixed in a groove in the connecting device 31 . in this case , the groove has a clearance 124 in the axial direction for movement of the retaining ring . in the connecting section of the pressurized storage tank 11 , an axial bore 112 leads out of the interior of the pressurized storage tank 11 in the direction of an outer boundary of the connecting section of the pressurized storage tank 11 . this axial bore 112 is intersected by a transverse bore 111 , allowing a fluid flow to be carried onward from the axial bore 112 via the transverse bore 111 . the transverse bore 111 extends as far as the end of the connecting section of the pressurized storage tank 11 , and therefore , a connection between the interior of the pressurized storage tank 11 and the surroundings of the pressurized storage tank 11 is established via the transverse bore 111 . thus , fluid may thus pass into the pressurized storage tank 11 and may emerge from the storage tank 11 via the transverse bore 111 . the transverse bore 111 is aligned in such a way that it opens into bore 32 in the connecting device . this alignment of the bores 111 and 32 relative to one another is facilitated particularly by the plug - in joint , in contrast especially to screwed joints . moreover , the radial alignment of the pressurized storage tank 11 may be secured by way of the centring feature 129 , e . g . a centring pin . sealing rings 130 and 131 are arranged on both sides of the transverse bore 111 , between the connecting section of the pressurized storage tank 11 and the connection block of the connecting device 31 . in the embodiment illustrated in fig5 , the connection between the pressurized storage tank 11 and the connecting device 31 is secured by way of a nut 118 . in the embodiment illustrated in fig6 , the connection between the pressurized storage tank 11 and the connecting device 31 is established by way of a screwed connecting element 123 , but the connection could also be embodied as a plug - in joint . the connection likewise uses centring features 129 . in this embodiment , the axial bore 112 is continuous , being embodied as a through opening . moreover , the connecting device 31 also has an opening 125 in the region of the open end of the axial bore 112 , allowing components such as a manual valve , for example , to be screwed or plugged into the opening . in the opening of the axial bore 112 there is a screw 132 , which , when positioned in the same plane as the pressurized storage tank 11 , seals off the opening from the outside and exposes the bores 111 , 112 , or , when fully screwed in , seals off the axial bore 112 from the transverse bore 111 . in a defined state of the screw 132 , it exposes an additional opening 133 to the outside . the additional opening 133 is designed in such a way that a service line , for example , may be screwed in . the opening 125 may be covered by way of a cover 140 made of plastic or sheet metal , said cover being embodied in such a way that it is arched outwards or tears if there is damage to the seal , in particular to the sealing ring 130 . the cover 140 is furthermore embodied in such a way that non - destructive removal is not possible and hence unauthorized access is prevented or is evident . in the embodiment illustrated in fig7 , the connecting section of the pressurized storage tank 11 additionally has a predetermined breaking point 116 and a flow limiter 113 , which are arranged in such a way that the flow limiter 113 remains in the pressurized storage tank 11 when there is a break at the predetermined breaking point 116 . the axial bore 112 is embodied in such a way that a flow limiter 113 and / or a filter 114 and / or a sealing seat 115 may be screwed in or plugged in . fig8 illustrates a schematic illustration of a design of the connection between the pressurized storage tank and the connecting device from above . in this case , bolts are arranged as clamp connecting elements 122 in bores 126 which overlap with the groove in the pressurized storage tank 11 . this embodiment is configured in such a way that rapid mounting and rapid removal are made possible by way of the accessible socket 127 for the fixing and removal tool and the bore 128 . fig9 illustrates a schematic illustration of another embodiment of the connection between the pressurized storage tank 11 and the connecting device 31 from above . in this case , screws are used as screwed connecting elements 123 , the thread of said screws being formed along only part of the length of the screw . the front part of the connecting elements 123 , which ensures that the pressurized storage tank 11 is retained on the connecting device 31 , is embodied as an unthreaded stud . given appropriate dimensioning of the groove , freedom of movement for the connecting element 123 is thereby ensured , and hence play is allowed for the pressurized storage tank 11 mounted in the connecting device 31 . seals 141 , 142 are visible on the screwed connecting elements 123 . these seals may be provided by way of paint or spot welds , for example . embodiments are directed to a pressurized storage tank arrangement that has a highly flexible structure and provides advantageous conditions for movement of fluid within the arrangement . although embodiments have been described herein , it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure . more particularly , various variations and modifications are possible in the component parts and / or arrangements of the subject combination arrangement within the scope of the disclosure , the drawings and the appended claims . in addition to variations and modifications in the component parts and / or arrangements , alternative uses will also be apparent to those skilled in the art .
