Definitions

  • the invention concerns a device for storing gas under high pressure as defined more in detail in the preamble of claim 1.
  • the invention concerns moreover a method for manufacturing such a device as well as the use of such a device.
  • Devices for storing gases under high pressure are known from the general state of the art. These consist typically of a compressed gas tank and a valve provided thereon which is typically designed as a so-called On-Tank-Valve (OTV).
  • OTV On-Tank-Valve
  • the compressed gas tank himself is typically assembled in such a way that it includes two end elements which are designated as BOSS. These end elements enclose a tubular section via which the end elements are connected with one another to the compressed gas tank.
  • a further shortcoming lies in the great number of structural elements and consequently the great weight and the large space requirements for these structural elements. This is in particular a considerable shortcoming for the use of the device for storing gas in vehicles since the construction space and the weight are associated with a major shortcoming in terms of comfort and cruising range of the vehicle.
  • valve units must be arranged accordingly on both sides of the compressed gas tank, for instance to exhaust gases downwards when an overpressure safety valve has been released, the angular position must be adjustable then for at least one of the devices since due to the preset tightening torque no exact mounting position can be predetermined to achieve a sufficient seal during manufacture. This constitutes a considerable shortcoming in terms of seal and number of structural elements.
  • the object of the present invention is then to provide a device for storing gas under high pressure, in particular for storing hydrogen, by way of example in a fuel cell vehicle which avoids the stated shortcomings.
  • said object is solved by a device having the features mentioned in the characterising part of claim 1.
  • Advantageous embodiments and developments of he device are divulged in the depending claims.
  • the object is also satisfied by a method for manufacturing such a device with the features of claim 7.
  • An advantageous further development of the method results from the dependent subclaim.
  • a preferred use of the device is indicated finally in claim 9.
  • An advantageous further development of the method also results from the dependent subclaim.
  • a compressed gas tank is formed of two end elements as a tubular section arranged between the end elements.
  • the device includes moreover a valve unit with a valve housing which comprises pipe sections for feeding gas and functional elements accommodated in the valve housing.
  • the valve housing is formed as a single piece with one of the end elements.
  • the valve housing in particular the valve housing of the On-Tank-Valve, is designed as a single piece integrated into the respective end element, the so-called BOSS. Said assembly, which can be contemplated by principle also with the other end element, by way of example for a thermal
  • overpressure safety valve or similar enables to dispense completely with the
  • the functional elements of the valve can be screwed in directly in corresponding openings of the integrated structure composed of valve housing and BOSS.
  • the functional elements can then comprise one or several of the following elements according to a particularly advantageous further development of the device of the invention:
  • additional elements for example can also be contemplated for monitoring and/or operating the functional elements or the refuelling and extraction function through the valve unit in the integrated structure composed of BOSS and valve housing.
  • the functional elements are respectively screwed in in axial and/or radial direction from the side facing away from the compressed gas tank formed of individual locating bores of said at least one end element with integrated valve housing.
  • the functional elements can preferably be screwed in individually into the corresponding bores so that said functional elements can be mounted easily and efficiently and if required dismounted, maintained and/or exchanged.
  • the end elements include devices for mounting the compressed gas tank, whereas a floating bearing is formed on one of the end elements and a fixed bearing is formed on the other end element, by said mounting device or by including said device.
  • Such bearings wherein particular a fixed bearing is provided in the area of the end element with the functional elements for extraction of the gas and wherein the floating bearing is arranged on the opposite side, enable an ideal assembly of the compressed gas tank, for instance on a supporting frame and with minimal construction space requirements.
  • the bearing elements can be designed through their immediate integration to be stable into the respective BOSS and with small construction space requirements.
  • parts of the bearing elements, of the valve housing and of the end element can be designed as a single piece and integrated into each other in order to save on construction space which is beneficial to the storage volume in the device with the same construction size of the device.
  • both of the connecting elements are designed for accommodating respectively at least one functional element. It can be for instance on the one side of the compressed gas tank an assembly which accommodates several functional elements .such as for instance the extraction valve, a manual shut-off valve, an overpressure safety valve, in particular with thermal release unit as well as a temperature and/or pressure sensor. This side then represents the main functionality of the valve unit.
  • a further overpressure safety valve with thermal release can be arranged on the opposite side so that in case of an overheated device, by way of example by fire, it can also be triggered if said side had been overheated even when the other side has been unduly overheated.
  • the extraction valve can be designed separately from the refuelling valve by way of example so that refuelling takes place on the one side and extraction the other side. Further variations can also be envisioned and are clearly visible for the man of the art analogically to the previous description.
  • the conventional structures require the valve units to be adjustable in angular position, structures which are used for instance in both end elements of a compressed gas tank, with considerable additional means implemented and in terms of sealing and assembly, which is extremely detrimental.
  • the method for producing the device according to the invention it can be taken into account that first of all both end elements are oriented relative to one another in terms of their distance and of their angular position. Subsequently, they are connected to one another via the tubular section and then constitute the compressed air tank with a valve housing integrated to of at least one of the end elements.
  • the necessity of an adjustment in angular position can be dispensed with, which constitutes an additional advantage in terms of assembly on. the one hand and in terms of means implemented to achieve a sufficient seal on the other hand.
  • At least one layer of the tubular section is braided and/or wound of a fibre material and then hardened by means of a plastic matrix.
  • the structure of the tubular section can consist in particular of one or several layers. So a connection of both end elements can be provided via a flexible internal layer, sealed against the gas in use, a so-called internal liner.
  • This internal liner which consists for instance of a thin plastic sleeve, is then braided or wound with fibre bundles.
  • These fibre bundles can be pre-impregnated with a matrix material or are applied together with a matrix material.
  • the matrix material which can be designed in particular thermoplastically, can then be fused accordingly at the next stage or while the fibre bundle is applied so that the layer including the fibre bundle hardens to become a fibre-reinforced plastic layer which guarantees an accordingly high mechanical stability against the pressure prevailing in the compressed gas tank.
  • high tightness can be achieved through the internal liner preferably used, which accordingly offers resistance to the gas used without the internal liner being able to absorb high pressures since said layer can be made of a fibre reinforced plastic material.
  • the preferred use of such a device according to the invention then consists in storing gas as a propellant for a vehicle, in particular a fuel cell vehicle.
  • the device enables with minimum means implemented, with small construction space or high storage capacity and corresponding small weight, to provide a very good storage possibility for gases under high pressure. It can be for instance compressed natural gas or in particular hydrogen. Said gas is ideal indeed to drive a vehicle by way of example via an internal combustion engine or in the case of hydrogen in particular via a fuel cell, which generates electrical driving power for the vehicle.
  • the structure of the device can thus provide a light and compact system with high storage capacity which is extremely advantageous in particular for the contemplated vehicle use since it provides ideal prerequisites for vehicle use in terms of propellant consumption and cruising range.
  • a particularly preferred use of the device can lie in that hydrogen as gas is stored at a rated pressure of more than 600 bars.
  • hydrogen is now stored at rated pressures of 700 bars so that the device must withstand pressures up to approx. 900 bars according to all safety requirements.
  • a high carrying capacity of the used materials and a smallest possible number of structural elements, which must be sealed relative to one another for the high rated pressure constitute a decisive advantage. This can be secured ideally by the device according to the invention.
