Definitions

  • cryogenic container and ancillary systems for filling and venting the cryogenic container
  • the invention relates to a system comprising a cryocontainer and an ancillary system for filling and venting the cryocontainer, the ancillary system comprising a connection line led into the first cryocontainer and a filling coupling being connected to the connection line.
  • cryocontainers mount cryocontainers on a motor vehicle, in which liquefied gas (e.g. LNG, "Liquid Natural Gas”) is stored, which is used, for example, as fuel for the motor vehicle.
  • liquefied gas e.g. LNG, "Liquid Natural Gas”
  • a connection line, via which the cryocontainer can be filled, is led into each of the cryogenic containers.
  • each of the cryocontainers also has a so-called vent coupling, which is used to specifically release gas from the respective cryocontainer to reduce the pressure in the cryocontainer, i.e. the cryocontainer is "vented".
  • a vent line is led into the respective cryocontainer.
  • the filling system and the vent system form what is known as the ancillary system of the cryocontainer.
  • the prior art has the disadvantage that the lines of the ancillary system on the motor vehicle are complicated to lay.
  • the space on the motor vehicle for lines to be laid is extremely tight and any gain in space can be used to enlarge the cryocontainer in order to store more cryofluid.
  • a system comprising a cryocontainer and an ancillary system for filling and venting the cryocontainer, the ancillary system comprising a connection line led into the first cryocontainer and a filling coupling being connected to the connection line, with a shut-off valve in the connection line is provided and by means of a branch line a non-return valve opening in the filling direction is connected in parallel to the shut-off valve, so that the cryocontainer can be filled via the filling coupling when the shut-off valve is closed and vented via the filling coupling or a separate valve connected to the connection line when the shut-off valve is open.
  • the solution according to the invention creates a possibility with which only a single connection line has to be led into the cryogenic container, i.e. the vent line and the filling lines no longer have to be connected separately to the cryogenic container.
  • the number of pipe penetrations on the cryocontainer for the ancillary system for filling and venting can be reduced from two to one.
  • the inventive solution contributes to the fact that heat losses of the cryogenic containers are reduced, because cryogenic containers are double-walled, vacuum-insulated containers and all pipelines that are connected to the actual storage volume must penetrate the insulation vacuum and are a thermally conductive and mechanical connection between an inner tank and an outer container .
  • the filling coupling is a combination coupling for filling and venting the cryocontainer, or a separate vent coupling can be provided for venting.
  • the filling coupling and the vent coupling can be connected to already existing gas station connections, which ensures backward compatibility.
  • cryocontainers mount two cryocontainers on a vehicle.
  • the cryocontainers are usually mounted on the left and right on the support frame of the vehicle between axles of the vehicle.
  • both cryocontainers have accessible filling couplings on the side of the motor vehicle so that the cryocontainers can be refueled individually.

  • another filling coupling can be connected to the connecting line, whereby the filling couplings are accessible at different points, e.g. opposite sides of the vehicle.
  • a further filling coupling can preferably be connected to the connecting line, the filling couplings being accessible on opposite sides of the motor vehicle.
  • an overpressure valve is connected to the first connection line and preferably a further overpressure valve is also connected to the second connection line.
  • a further overpressure valve is also connected to the second connection line.
  • the invention provides a motor vehicle comprising a vehicle frame and said system, wherein the cryocontainer is mounted on a first side of the support frame and the further cryocontainer is mounted on one of the first opposite second sides of the support frame, the ancillary system being installed on the motor vehicle in such a way that that the filling coupling is accessible on the first side or on the second side.
