Description

  • [0001]
    The present invention relates to a gas filling and distribution head equipped with a connection interface and to a tank equipped with such a head.
  • [0002]
    The supply of gas to gas-consuming devices, for example fuel cells, presents numerous problems. In particular, it is important to simplify and secure the supply by, in particular, working along the principle of exchanging an empty tank for a full tank.
  • [0003]
    This problem is all the more sensitive because the current trend is to increase service pressures with a view to offering a better ratio between the mass of stored gas and the overall mass of the tank, combined with smallness of size.
  • [0004]
    In addition, such systems are becoming more widespread, involving use of the gas by non-specialists (professionals such as nurses, laboratory workers, for example, or by the general public such as DIY enthusiasts, motorists, etc.).
  • [0005]
    One objective of the systems for storing fluid and of the devices for filling them and/or for tapping fluid off from them, is to make the handling operations needed to exchange an empty tank for a full tank easier. The storage systems have in addition implicitly to provide a level of safety that allows the handling operations to be performed by non-specialists while at the same time improving the safety and productivity in tank processing centers.
  • [0006]
    It is known practice for gas to be stored in liquid form. In known solutions (CO2 for example), this is performed quite naturally and does not require the use of special facilities. In most cases (for example that of hydrogen), however, it is necessary to maintain temperature conditions such that the use of special facilities is compulsory (thermal insulation, control of boiling or “boil-off”). This operation makes the solution for storing liquid somewhat irrelevant because it is far too complicated and ill suited to the idea of exchanging an empty one for a full one.
  • [0007]
    Solutions for storing gas in gaseous form conventionally include cylinders equipped with a simple valve which, if open, places the user in direct contact with the storage pressure. It is therefore necessary, in order to use the gas, to connect up equipment (pressure regulators, flow meters, etc.) and this entails tooling and tricky operations. These operations become all the more risky when the user is not a professional (with the risk of leaks, forcible expulsion of parts, etc.).
  • [0008]
    Lightweight small-sized gas refills are known, these proposing a solution which is to provide the canister with a valve that has no actuating member, but the disadvantage with these is that the gas is delivered at the storage pressure.
  • [0009]
    In order to guard against the risks associated with the high pressure, canisters or cylinders may be equipped with a regulating valve which, as far as the user is concerned, allows him access only to a reduced pressure. This solution has the disadvantage of creating a protruding part on the cylinder. This protruding part therefore needs to be protected. This protection is generally formed by a bonnet. On the whole, the weight and size are increased and incorporating the cylinder into the application that requires the gas may lack simplicity.
  • [0010]
    Furthermore, most reserves of gas delivered to customers need to be mobile. In an extreme case, the self-contained gas source may have to be deployed and to accompany the gas-consuming application, for example to supply a fuel cell at an isolated site or to accompany fire fighters attending an emergency.
  • [0011]
    Each customer or customer family has its own specific requirements that have to be met as best possible. The consequence of this is to make the industrial organization more complicated because it is necessary to manage a wide variety of products (fluid/tank pairing and fluid delivery conditions).
  • [0012]
    One problem that needs to be solved is, on the one hand, to offer the user and/or the operator means that make it easier for him to transport and to handle a reserve of gas and, on the other hand, to offer the user means that will allow him to customize the design of a reserve of gas in order to meet the requirements of his particular application and to allow the operator flexibility that will allow him to manage the variety of products needed to meet the requirements of his customers.
  • [0013]
    Of the solutions for storing gas in gaseous form, cylinders equipped with a simple valve are favored by the operators and by industry for questions of managing the population of cylinders. If open, the simple valve places the user directly in contact with the fluid at its storage pressure. It is therefore necessary, in order to use the gas, to connect up hardware (pressure regulator, flow meter, etc.) which demands tooling and tricky operations, accompanied by the risks involved in this type of operation when the user is not a professional. This solution is therefore not favored by the end-user.
  • [0014]
    Better favored by the end-user is the regulating valve attached to the cylinder delivering the fluid as the pressure needed by the application. However, use of such a regulating valve places significant constraints upon industry particularly in terms of managing the population of cylinders, maintenance, interface with the filling equipment, etc.
  • [0015]
    Thus, none of the aforementioned existing solutions simultaneously considers these specific requirements of industry and those of the customer.
  • [0016]
    In known designs for storing gas under pressure, the valve incorporates a regulating device which is positioned inside the volume of the cylinder (cf. for example EP-A-1316755). These known devices make it possible in part to limit the volume of the valve but require the user to perform numerous handling and coupling operations in order to fill and tap off from the cylinder.
  • [0017]
    Thus, none of the aforementioned existing solutions simultaneously considers these specific requirements of industry and those of the customer.
  • [0018]
    It is one object of the present invention to alleviate all or some of the disadvantages recalled hereinabove of the prior art.
  • [0019]

  • [0076]
    FIG. 1 depicts an oblong tank body 1 having a cylindrical main part 10 and two substantially dome-shaped ends, one lower 11 and one upper 12. The rounded upper end 12 has a filling and distributing head 2. As depicted, the filling and distribution head 2 in particular comprises a connection interface 3, a tell-tale indicating the fill level 4, an anti-knock shield and a central orifice 6 providing access to the inside of the tank 1.
  • [0077]
    FIG. 2 shows an alternative form of the gas storage assembly (tank 1) according to the same embodiment, with an optional casing 100 more or less entirely covering the external surface of the tank 1. The casing 100 (or jacket) is designed to protect the tank 1 against any knocks or droppage.
  • [0078]
    The oblong casing 100 of dimensions tailored to the tank 1 has its rounded lower end 111 made to correspond to the lower end 11 of the tank 1. The cylindrical central part of the casing 100 hugs the cylindrical part 10 of the tank 1. The rounded upper end 112 of the casing for its part covers the upper end 12 of the tank 1.
  • [0079]
    Slots 102 on the periphery of the upper end 112 of the casing allow the casing 100 to be slipped over the tank 1.
  • [0080]
    At the upper end of the casing in particular, a collar 103 fitted with a closure 104 (of the touch-and-close type or press-stud type or any other equivalent means) may be provided to hold the casing 100 in place on the tank 1.
  • [0081]
    The casing 100 on its periphery has ergonomic imprints 101 making the whole easy to hold. The casing 100 is preferably made of thermoformed high-density foam but any other material such as neoprene, an elastomeric material, etc. may be considered.
  • [0082]
    Reference is now made to FIG. 3 in which the tank 1 comprises a sealed internal casing 13 (or “liner”), for example made of aluminum alloy or the like, intended to contain the fluid and particularly gas under pressure. The casing 13 is reinforced on its external surface by a winding of carbon fiber filaments 14 bonded together with epoxy resin or any other equivalent means.
  • [0083]
    An oblong filling head 2 is positioned in the tank 1, at the orifice of the tank 1, inside the casing inner 13.
  • [0084]
    The body 20 of the filling and distribution head 2 is mechanically connected to the casing 13 by virtue of a screw thread 21 collaborating with a tapped thread formed on the casing 13. An annular seal 7 is positioned in a groove formed in the casing 13. The groove lies at the upper end of the casing 13 and is enclosed by the body 20 of the filling and distribution head 2 so as to provide sealing between the body 20 and the inside of the tank 1.
  • [0085]
    The filling and distribution head 2 in its lower part comprises a pre-regulating cartridge 22 is screwed into its body 20 by virtue of a screw thread/tapped thread system 221.
  • [0086]
    Downstream of the pre-regulating cartridge 22 (toward the top of the cartridge 22), the filling and distribution head 2 comprises a low-pressure chamber 23. Sealing between the inside of the tank 1 and the low-pressure chamber 23 is afforded by the combination 222 of an O-ring and of anti-extrusion rings positioned between the cartridge 22 and the body 20 of the head 2.
  • [0087]
    The pre-regulating cartridge 22 comprises, working from upstream to downstream (that is to say from its lower part toward its upper part in FIG. 3), a filter 24, a threaded ring 25 and a pre-regulating valve 26. The filter 24 is held in the cartridge 22 by an elastic ring 241 housed in a groove 223 formed in the body of the cartridge 22.
  • [0088]
    The pre-regulating valve 26 is subjected to the action of a spring 261 moving it toward a seat 27 held in the cartridge 22 under the action of the threaded seat holder 271. The valve 26 is subjected to the force of the valve spring 261 and to the force of the pressurized gas.
  • [0089]
    The upper end of the valve 26 is equipped with a stem 1261 extending upward and the end of which is in contact with a pre-regulating piston 28. The piston 28 for its part is urged toward the valve 26 by a spring 281. Because of the force of the spring 281 and the action of the gas on the cross section 282 of the piston 28, the valve 26 acts as a pressure regulator.
  • [0090]
    During phases in which gas is tapped off from the tank 1, the gas contained in the tank 1 under high pressure passes, while its pressure is being reduced, through the pre-regulating cartridge 22 toward the low-pressure chamber 23.
  • [0091]
    The pressure-regulated gas then passes through the piston 28 via a drilling 283 formed in the body of the piston, to emerge in a chamber 32 situated in the body 30 of a connection interface 3. The connection interface 3 is mounted at the upper end of the head 2.
  • [0092]
    The chamber 32 comprises an isolating valve 8 which is sealed with respect to the inside of the tank by a seal 81 that seals against the body 30 of the connection interface 3.
  • [0093]
    The default setting of the isolating valve 8 is closed. The isolating valve 8 is, for example, a valve of a conventional type, such as a valve comprising a fixed tubular body and a rod capable of moving inside the body to make the valve allow the passage of fluid or prevent the passage of fluid depending on the position of the rod.
  • [0094]
    The valve 8 can be actuated by a valve driver described in greater detail hereinafter and belonging to a system that receives the storage assembly or to a gas distribution head or to a cylinder filling connector.
  • [0095]
    The upper end of the connection interface 3 projects out from the filling and distribution head 2 of the tank 1.
  • [0096]
    This outer part of the connection interface 3 comprises four projecting pins 35 (bayonets) positioned 90° apart to allow for attachment of a receiving system belonging to a storage assembly or to a gas distribution head or to a filling connector. Of course, this exemplary embodiment is nonlimiting, particularly given the considerable number of conceivable combinations of number, shape and position of pins and corresponding polarizing (that is to say geometrical identity) options available. In addition, other attachment members that perform the same function are conceivable, including screw/nut connections, a latch lock lever, a retractable catch, etc.
  • [0097]
    The outer part of the connection interface 3 comprises a tubular housing forming an accommodating region 36 the purpose of which is to accept and to guide a mating tubular end of a receiving system or of a gas distribution head or of a filling connector as described hereinafter.
  • [0098]
    To this end, the mating tubular end of the control member intended to be connected to the tank 1 comprises an O-ring seal and possibly an anti-extrusion ring to ensure the continuity of the seal between the control device and the tank 1.
  • [0099]
    The external part of the connection interface 3 preferably comprises a removable protective membrane 33 intended to avoid the ingress of particles or dirt into the accommodating region 36 and that might cause the system to malfunction. The membrane 33 is, for example, made of precut shape-memory polymer. The membrane is, for example, held at the inlet of the accommodating region 36 by a plastic anti-impact shield 34. Of course, any other form of embodiment for protecting the inlet of the accommodating region is conceivable, for example a film that has to be punctured, or a sticker that has to be removed, or the like.
  • [0100]
    Thus, when the tubular end of a control device (receiving system or gas distribution head or a filling connector) is introduced into the receiving region 36, the precut membrane 33 will move aside against the surface 37 of the connection interface 3. For example, the shape-memory protective membrane 33 is precut into four “petal-shaped” lobes. As it enters, the male tubular end of a control device will push the four lobes back against the surface 37 of the connection interface 3. The lobes will automatically return to their initial position (FIG. 3) when this same tubular end is extracted.
  • [0101]
    The tank 1 comprises a tell-tale 4 comprising a body 41 screwed into the body 20 of the device of the filling and distribution head 2 by means of a screw thread system 47. Sealing between the tell-tale and the filling head 2 is provided by means of a stressed metal seal 42. A moving spindle 43 is guided in the body 41 of the tell-tale 4. Sealing between the spindle 43 and the body 41 is afforded by the combination 45 of an O-ring seal and of an anti-extrusion ring.
  • [0102]
    The spindle 43 of the tell-tale 4 is subjected to the opposing forces of a return spring 44 and of the pressure of the gas contained in the tank 1 carried through the tell-tale 4 via a screw thread 21 and drillings 46.
  • [0103]
    When the action of the gas pressure exceeds the force of the return spring 44, the end of the spindle 43 emerges into a viewing chamber 48 formed in the body 41 of the tell-tale 4. Thus, the tell-tale indicates that the gas store is full (the pressure of the gas contained in the tank 1 is optimal). If not, the end of the spindle 43 does not emerge into a viewing chamber 48, this indicates that the gas store is not full (the pressure of the gas contained in the tank 1 is below the optimum pressure).
  • [0104]
    A safety device (of the type that melts under the action of heat and/or discharge valve, rupture disk, etc. type) may be fitted to the tank 1 via a port 9 formed in the body 20 of the filling and distribution head 2. This safety device may be fed with the gas contained in the tank 1 via a cut 42 machined in the screw thread 21 and via drillings 91.
  • [0105]
    FIGS. 4 and 5 illustrate a filling connector that has a body 300, a connection interface 303 and a control lever 302. The body 300 is connected to the end of a filling hose 317 by a screw thread 318 (for example a tapered screw thread sealed with PTFE (polytetrafluoroethylene) tape).
  • [0106]
    The filling hose 317 supplies the filling circuit via a filling pipe 319. The filling pipe 319 is dirt free thanks to a filter 315 held in place in the body 300 under the effect of an elastic ring 316 held captive in a groove formed in this same body.
  • [0107]
    A manual control lever 302 that can rotate about a spindle 330 is capable of transmitting a translational movement to a valve driver 310 via a cam 320 which rubs against a wear plate 312. Of course, the pivoting manual lever 302 may be replaced by any analogous system, for example an automatic control.
  • [0108]
    There is a spring 311 in the body 300 in order constantly to keep the end 321 of the valve driver 310 held against the wear plate 312 in contact with the cam 320.
  • [0109]
    To ensure the continuity of the cross section for the passage of gas through the filling pipe 319, the exterior surface 322 of the valve driver 310 is of hexagonal cross section while the cylindrical surface 323 has two flats. The dynamic sealing of the valve driver 310 with respect to the body 300 is provided by a combination 313 of an O-ring seal and of an anti-extrusion ring, these being held in their housing by a gland 314.
  • [0110]
    As depicted more specifically in FIG. 6, the connection interface 303 of the filling connector collaborates with the connection interface 3 of the tank 1.
  • [0111]
    More specifically, the projecting pins 35 (bayonets) of the connection interface 3 of the tank 1 enter channels or millings 304 in the connection interface 303 of the filling connector. The pins 35 position themselves in the respective housings 306 at the closed ends of the cranked channels 304.
  • [0112]
    As they enter the channels 304, the pins push and temporarily retract a safety catch 305. When the pins are in their housing 306, the catch 305 is returned to its initial locking position under the action of a spring 309. In this way, the catch 305 traps two diametrically opposed pins 35 in their respective housings 306 b. In this position, the filling connector is locked onto the tank 1.
  • [0113]
    The filling connector has a tubular end 308 which becomes housed in the accommodating region 36 of the connection interface 3 of the tank 1. Sealing between these two surfaces (the tubular end 308 and the accommodation region 36) is provided by the combination 307 of a seal and of an anti-extrusion ring.
  • [0114]
    To open the valve 8 of the tank 1, the lever 302 is actuated in such a way that the cam 320 via the wear plate 302 acts on the valve driver 310 transmitting to it a translational movement that is passed on to the stem 82 of the valve 8.
  • [0115]
    The valve driver 310 therefore projects relative to the tubular end 308 and relative to the filling connection so as to allow it to dip down into the head 2 housed in the tank 1 in order to actuate the valve 8.
  • [0116]
    The cam 320 comprises a flat surface 325 that allows this position to remain stable. The valve closure 8 has to be performed manually by performing the reverse operation on the control lever 302.
  • [0117]
    The filling fluid can then be injected into the filling connector via the pipe 319.
  • [0118]
    The filling fluid passes in succession through the open valve 8, the chamber 32 and the drilling 283 of the pre-regulating piston 28. The surface 282 of the piston 28 is therefore subjected to the pressure of the gas which is stronger than the force of the spring 281.
  • [0119]
    This gas pressure moves the piston which thus moves free of the end of the stem 1261 of the pre-regulating valve 26.
  • [0120]
    The pre-regulating valve 26 is therefore opened by the action of the pressure of the gas passing through the pre-regulating cartridge 22 in the opposite direction in order to return to the tank 1.
  • [0121]
    At the end of the filling operation, once the high pressure in the filling pipe has been dumped, the pre-regulator can be reactivated. The valve 8 is closed again by action on the control lever 302 of the filling connector.
  • [0122]
    Once all of the gas contained in the entire filling circuit (the entire volume downstream of the valve 8) has been dumped, the filling connector can be uncoupled through a process that is the reverse of the one described hereinabove.
  • [0123]
    To uncouple the filling connector, the control 301 of the catch 305 has to be pulled manually against the force of the spring 309 in order to free the protruding pins 35 (bayonets) from their housings 306 and 306 b following the path of the cranked milled slots 304. The tubular end 308 comes free of the accommodating region 36, the precut membrane 33 returns to its original position preventing particles or dirt from entering.
  • [0124]
    FIGS. 7 and 8 illustrate a removable gas delivery head 150 comprising a control to open up the flow rate of gas 250, an annular knob to shut off the flow rate of gas 350, access 450 to the outlet coupling naturally closed off by a shutter to prevent contamination and a connecting interface 516. The gas delivery head 150 also comprises medium-pressure and low-pressure discharge valve discharge louvers 115 and a location 65 for information intended for the user and which may be in the form of a digital display offering customized autonomy information (or pressure gage or any other known means).
  • [0125]
    FIG. 9 illustrates the gas delivery head 150 according to the same embodiment, equipped with an outlet coupling 75 the orifice 70 of which is connected to a hose (not depicted) supplying the application.
  • [0126]
    Advantageously, the head 150 is shaped in such a way that
  • [0127]
    if the outlet coupling 75 is not connected, it is impossible to lock the control to open the flow rate of gas 250,
  • [0128]
    if the outlet coupling 75 is connected to the removable gas delivery head 150, it is possible to lock the control to open up the flow rate of gas 250, the shutting-off of the flow rate of gas being controlled by action on the annular knob 350 and a control 415 for unlocking the outlet coupling 75 is accessible,
  • [0129]
    if the outlet coupling 75 is suddenly disconnected while the control to open up the gas is active, the latter control is immediately disconnected.
  • [0130]
    FIG. 10 depicts details of the gas delivery head according to the same embodiment. The case that protects the delivery head 150 is made up of two half-shells 511 joined together by clips and two screws 135. The delivery head 150 contains, on the one hand, a body 512 comprising the various active gas-delivery components and, on the other hand, the user interface controls. In particular, the delivery head 150 comprises a control to open up the flow rate of gas 250, an annular knob to close off the flow rate of gas 350, and an access 450 providing access to the outlet coupling 75.
  • [0131]
    The lower part of the body 512 ends in a tubular end 514 with an O-ring seal 515 and a component 516 displaying symmetry of revolution which in this instance has four millings 161 positioned 90° apart. Of course, the invention is not restricted to this configuration and any other combination of number and positions of millings may be considered.
  • [0132]
    The lower part of the body 512 forms a connection interface that can collaborate with and be attached to the coupling interface of a tank 1 as described hereinabove and illustrated in FIG. 11. In FIG. 11, the gas delivery head 150 mates with and extends the protective jacket 100 of the tank 1.
  • [0133]
    Passing through the body 512 is a valve driver 17 which is dynamically sealed with respect to said body 512 by an O-ring seal 172.
  • [0134]
    The upper end of the valve driver 17 comes into contact with the spindle of the control to open up the flow rate of gas 250 when the latter is pressed and locked.
  • [0135]
    The spindle of the control to open up the flow rate of gas 250 may thus transmit a translational movement to the valve driver 17 which itself passes this translational movement on to the valve stem 8 of the tank 1 described hereinabove. The valve driver 17 therefore projects beyond the lower part of the body 512 to enter the head 2 of the tank 1, so as to open up the flow rate of gas.
  • [0136]
    The fluid stored in the tank 1 then enters the body 512 by the annular orifice 121. The annular orifice 121 simultaneously, via the transverse drilling 122, supplies a medium-pressure safety valve 123 and a pressure-regulating stage 58.
  • [0137]
    The medium-pressure safety valve 123 comprises a discharge valve 124 the opening of which is determined by the calibration force of a spring 125. The medium-pressure safety valve 123 is formed in such a way as to allow surplus pressure to be discharged through the louvers 115 formed in the two half-shells 511.
  • [0138]
    The pressure-regulating stage 58 comprises a mechanism enclosed in a cartridge 88 which is screwed into the body 512 and sealed with respect to the latter by an O-ring seal 881.
  • [0139]
    Gas enters the pressure-regulating stage 58 by passing through a filter 881 held by an elastic ring 582 held captive in a groove formed in the body 512. The entry of gas into the pressure-regulating stage 58 is also via the passage around a spacer piece 83 that allows the fluid to arrive radially and uniformly at a pressure-regulating valve 84.
  • [0140]
    As a result of the force of a valve spring 85 and of the action of the gas, the pressure-regulating valve 84 collaborates with a seat 86. The seat 86 is held in place in the cartridge 88 under the action of a threaded seat holder.
  • [0141]
    The valve 84 is equipped with a stem 841 extending upward and the end of which is in contact with a metal bellows 89. The metal bellows 89 is held in a sealed manner inside the body 12 under the combined action of a screw-on cap 891 and an O-ring seal 893. The valve 84 is subjected to the force of a pressure-regulating spring 891 preloaded by a pressure-regulating screw 892 and the force of the gas on the cross section of the metal bellows 89. Thus, the valve 84 regulates pressure.
  • [0142]
    Advantageously, the pressure-regulating screw 892 is adjustable so as to allow the user to vary the spring force and therefore the pressure regulation.
  • [0143]
    As depicted schematically in FIG. 14, a drilling 200, 355, formed in the body 12 allows the pressure-regulated gas to pass from inside the metal bellows 89 to an outlet connection 95 (FIG. 10).
  • [0144]
    At the same time, the drilling 200, 211 formed in the body 12 allows the pressure-regulated gas to pass between the metal bellows 89 and a low-pressure discharge valve 201 (of the same type as the valve 123 described hereinabove).
  • [0145]
    The set points at which the discharge valves 123 and 201 open are chosen to suit the requirements of the application. The medium-pressure valve 123 is, for example, rated to discharge pressures in excess of 20 bar to the outside while the low-pressure discharge valve 201 is rated to discharge pressures in excess of 400 mbar to the outside.
  • [0146]
    The outlet connection 95 is screwed in a sealed fashion into the body 12. This male outlet connection comprises a skirt 591 containing a shut-off device 592 which is closed by default and sealed against the said skirt 591 by the action of a spring 93.
  • [0147]
    The shut-off device 592 prevents, on the one hand, the ingress of particles and dirt into the gas circuit when the outlet coupling 75 is not connected. In addition, the shut-off device 592 prevents any flow of fluid to the atmosphere in the event either of forced action on the opening control 250 while the outlet coupling 75 is not connected, or if the outlet coupling 75 becomes disconnected.
  • [0148]
    The outlet coupling 75 is made up of a body 71 containing a shut-off member 72. The shut-off member 72 is subjected to the action of a spring 73 so that by default it is closed and sealed against said body 71.
  • [0149]
    This shut-off member 72 on the one hand prevents the ingress of particles and dirt into the gas circuit when the outlet coupling 75 is not connected and on the other hand prevents the fluid contained in the supply pipe of the application from being dumped to the atmosphere if said outlet coupling 75 becomes disconnected. When the outlet valve 75 is connected to the male outlet connection 95, on the one hand, the circuit becomes sealed under the action of an O-ring seal and, on the other hand, the circuit is opened by virtue of the mutual actions of the two shut-off members 72 and 592.
  • [0150]
    The tank 1 comprises a pre-regulating device incorporated into its neck and, possibly, also incorporated into this same neck, an isolating member. Thus, the very high pressure (the storage pressure) is isolated and the user is protected. The projecting part of the tank contains no high pressure and need not be protected by a bonnet.
  • [0151]
    The unique inlet/outlet connection interface of this tank is of the quick-coupling type and requires no tooling. Advantageously, this tank 1 can be refilled only with a special-purpose filling connection that collaborates with the unique connection interface of the tank. Access to this interface is found along the main axis of the tank 1, making it possible to conceive of automated filling solutions.
  • [0152]
    The idea of the automatic dispensing of these canisters, cylinders or tanks may be conceived of for applications both professional and for the general public. Delivery of gas entails either inserting the cylinder, canister or tank into a receiving housing equipped with means of opening the valve and of regulating the gas to suit the application, or connecting a special-purpose head provided with these very means.
  • [0153]
    Making the connections on the axis of the tank simplifies the handling operations and implicitly improves safety. The interfacing between cylinders, canisters or tanks and the accommodating system or special head is performed in such a way that the connection can be made only if the gas being delivered is actually that expected by the application.
  • [0154]
    FIG. 12 depicts the gas delivery head 150 mounted on its gas source (tank 1) as described hereinabove. The tank 1 is guided and enclosed in another type of protective jacket 100 with an attached bottom 133. The protective jacket 100 is hollow and on its interior surface has at least one region comprising longitudinal flexible strips 328 (cf. FIG. 13).
  • [0155]
    The strips 328 secured to the internal wall of the jacket 100 both immobilize the tank in said jacket 100 and compensate for geometric variations thereof resulting in particular from its internal pressure and its manufacturing tolerances. Furthermore, the strips 328 are able to absorb the energy generated if the tank thus clad is dropped or knocked.
  • [0156]
    The attached bottom 133 of the casing 100 has a helical screw thread 331 intended to be screwed into a helical cut 321 in the body of the jacket 100. The removable bottom 133 thus makes it easier to mount and secure the tank 1 in said protective jacket 100. In addition, the removable bottom 133 means that customary maintenance operations performed on the tank 1 will not be impeded.
