Definitions

  • the present invention relates to a gas supply device with a plurality of gas bottles inserted into a compressed gas container, the compressed gas container being connected in a gas-tight manner to a connection point in the operating position and the inside of each gas bottle communicating with the inside of the compressed gas container via a small opening serving as a throttle point.
  • a gas supply device of the type mentioned is known. It is a pressurized gas container exposed to the effects of a projectile. Several closed gas bottles with a relatively small opening are inserted next to one another in the compressed gas container. This arrangement prevents the entire contents from suddenly flowing out at one point when the compressed gas container bursts. The gas flows from the gas bottles used through the relatively small openings into the burst compressed gas container, the throttled content of the gas bottles being emptied only relatively slowly through the small openings. The gas bottles that are firmly seated in the compressed gas container can be extremely thin-walled in this arrangement. However, this entails the risk that the gas cylinders used will also burst when the compressed gas container bursts.
  • this pressurized gas container is only suitable for pure gas filling.
  • this gas supply device With this gas supply device, the amount of gas that can be stored is relatively modest.
  • the pressurized gas container either consists of a commercially available carbon dioxide cartridge, which contains partially liquefied gas and is sealed by a membrane, or a permanently installed container that must be filled with liquid gas. If the running time of the LPG engine is to be increased, a larger container must be selected. However, the safety regulations require a heavy and expensive version for larger compressed gas tanks. The content of the commercially available carbon dioxide cartridges is given.
  • the compressed gas container is in a heat-conducting connection with a heat storage substance container. The heat storage substance used therein is intended to prevent the progressive drop in gas pressure as the gas flows out of the gas bottle.
  • the pressure drop is a consequence of the cooling of the gas in the transition from the liquid to the gaseous state in the gas bottle.
  • the heat storage substance must be heated sufficiently above the freezing or crystallization temperature before commissioning, otherwise it will have no effect.
  • the thermal conductivity of the heat storage substance is very low, especially in the solid state. Therefore, this substance can only be applied in relatively thin layers, e.g. 0.5 mm.
  • the heat emission and heat absorption time must be chosen long enough in minutes. For these reasons, heating the gas bottle with a heat storage substance is unsatisfactory.
  • the object is achieved in that the gas bottles inserted in the pressure gas container are pressure-resistant and each gas bottle is partially filled with a liquid gas and sealed with a push-on closure part before being inserted into the pressure gas container, and that each gas cylinder is sealed in a gas-tight manner and connected to the connection point Closure part is associated with an opening device that is effective when the operational readiness is created, at least one of which opens the assigned closure part under external force.
  • the pressurized gas container can be tubular and the gas bottles can be inserted one behind the other leaving a radial gap.
  • the width of the radial gap is advantageously between 2 and 20 percent of the diameter of the gas bottle.
  • the end carrying at least the gas bottle closest to the connection point can carry the closure part away from the connection point.
  • the ends of the closure part carrying the closure part, at least two gas bottles counting from the connection point, having an odd number and a subsequent even number, are advantageously turned towards one another in pairs.
  • the gas bottles can also be inserted at least next to one another in the compressed gas container. It is particularly advantageous if a plurality of gas cylinders with their ends facing the closure part and facing one another are inserted in pairs next to one another in the compressed gas container.
  • the opening device can be slidably inserted into the compressed gas container and can be provided with at least one mandrel. It is advantageous to arrange an opening device provided on both sides with at least one mandrel between two gas bottles with their ends facing the closure part.
  • the opening device can consist of sheet metal and have a plurality of guide tabs resting on the inner wall of the pressurized gas container at least in one direction from the sheet metal plane and at least one mandrel bent at least in one direction from the sheet metal plane and intended for pushing open the opening device.
  • the compressed gas container can be equipped with a tensioning device which pushes the gas bottles and the opening devices together.
  • the tensioning device can have two sub-devices acting one after the other in time, the first of which is only effective until the closure part of the first gas bottle is opened and the second until the closure parts of the remaining gas bottles are opened, the first sub-device being externally under the influence of force and the second one by the force Gas flowing from the first open gas bottle can be actuated.
  • the first sub-device is preferably the fastening means of the compressed gas container at the connection point.
  • the second sub-device advantageously consists, so to speak, of quasi separating the gas spaces of the individual gas bottles and being displaceably guided in the compressed gas container sealed pistons, the piston surfaces lying directly in front of the closure parts of the gas bottles being provided for thorns serving to open the closure parts.
  • two quasi-sealed pistons spaced apart from one another by a spring and carrying thorns on the side facing away from the spring, can be inserted in the tubular compressed gas container, and a simple quasi-sealed piston can be inserted at the other abutment points of the gas bottles .
  • the spikes can be hollow and open into the space between the two spaced pistons.
  • the second sub-device can also have a filled with a compressible medium, arranged in the interior of the compressed gas container, sealed by a wall that is at least partially flexible when the pressure inside the compressed gas container changes, the wall being partially supported on the compressed gas container and the flexible part relative to this wall the wall in the event of an increase in pressure in the compressed gas container moves in the direction of the gas bottles and the opening devices and causes them to be pushed together.
  • the wall supported on the compressed gas container can consist of a cylinder recessed in a gas-tight and liquid-tight manner in the closed end region of the pressure gas container, and the resilient part of the wall can be made of a gas-tight and liquid-tight seal on the side facing away from the closed end of the compressed gas container
  • a smaller piston which is designed to be gas-tight from the cylinder space and intended to push the gas bottles and the opening devices together, has a much smaller diameter than the plunger and has a piston, the space between the closed end of the compressed gas container and the two piston surfaces facing this end having an incompressible space Liquid is filled.
  • the compressed gas container consists of a material with high thermal conductivity and high specific heat, for example aluminum. It is also advantageous if the mass of the compressed gas container is at least seven times higher than the mass of the gas that can be stored in the gas cylinders.
  • the compressed gas container is advantageously also on its outer surface Provide ribs. Optimal results can be achieved if the surface of the pressurized gas container and the fins which can be coated with air is at least 20 CM 2 per gram of the gas which can be stored in the gas bottles.

  • four gas bottles 6 are inserted one behind the other in the direction of their longitudinal axes.

  • An opening device 8 is inserted between the ends of the gas bottles 6 that face each other and carry the closure membranes 7.
  • the opening device 8 is shown in perspective on a larger scale in FIG. 2. It is made from sheet metal by stamping and bending and has a plurality of guide tabs 9 which are bent perpendicular to the sheet metal plane and two mandrels which are bent out of the sheet metal plane in the center and are intended for piercing the sealing membrane 7.

After the breech ranes 7 are pierced, the gas can flow from the gas bottles 6 into the interior of the compressed gas container 1.
  • the gap 11 is dimensioned such that the gas finds an adequate flow channel.
  • the gap width is 2 to 20 percent of the diameter of the gas bottle 6.
  • the gas bottles 6 are partially filled with liquid gas. When gas is extracted, heat of vaporization is required, which is extracted from the environment.

  • the ribs 13 absorb a relatively large amount of heat from the environment and conduct this to the inner layers of the compressed gas container 1.
  • the surface of the compressed gas container 12 and the ribs 13 which can be air-coated is more than 20 cm 2 per gram of the two Gas bottles 6 stored gas. This measure ensures good heat absorption from the ambient air even during the operating time.

The only difference from these arrangements is that the cylinders containing a compressible medium are recessed in the plate 40 firmly connected to the pressure gas container 34 and not in a larger piston 28 and that the space between the closed end of the pressure gas container 34 and the plate 40 communicates with the gas space of the compressed gas container 34 and contains no liquid.
  • the plungers 30 assigned to the upper gas bottles 6 extend in a manner similar to that shown in FIGS. 12, 13 and 14 and cause all the gas bottles 6 to reach the 14 drawn end position with certainty.
  • the pressure in the pressure gas container 34 drops, the compressible medium enclosed in the cylinder space in front of the piston 29 expands again and pulls the plunger 30 back into the plate 40.
  • the compressed gas tank can be recharged.
