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.
- the filling lines of the two cryocontainers can be connected via a connecting line in order to refuel both cryocontainers at the same time via a filling coupling.
- a separate vent system is provided for each cryocontainer, with the two vent lines being able to be connected by means of a separate connecting line, so that both cryocontainers can be vented via a single vent coupling.
- the above-mentioned system comprises a further cryocontainer, the ancillary system comprising a further connection line led into the further cryocontainer and a connection line which connects the two connection lines in such a way that both cryocontainers are filled via the filling coupling and preferably via the The filling coupling or the vent coupling can be vented.
- the further cryocontainer can basically be designed as known from the prior art, with at least common refueling being made possible via the connecting line.
- the connecting line could, in one embodiment, open into both the filling line and the vent line.
- the connecting line could comprise a check valve that can be opened in the direction of the further cryocontainer and a shut-off valve connected in parallel thereto.
- cryogenic containers are equipped with a combined filling and venting system with only one connection line each.
- a further shut-off valve is provided in the further connection line and by means of another In the branch line, a further check valve opening in the filling direction is connected in parallel to the further shut-off valve.
- 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.
- This motor vehicle is designed in such a way that the slim design of the ancillary system provides more installation space for further components or larger cryocontainers with more storage volume.
- the motor vehicle is particularly preferably designed such that a filling coupling and a vent coupling or a combined filling and vent coupling is / are accessible on the first side and the second side.
- a filling coupling and a vent coupling or a combined filling and vent coupling is / are accessible on the first side and the second side.
- Figure 1 shows a motor vehicle with two mounted cryocontainers.
- FIG. 2 shows two cryogenic containers and an ancillary system according to the prior art.
- FIG. 3 shows a cryocontainer and a section of the ancillary system according to the invention.
- FIG. 1 shows a motor vehicle 1 with a support frame 2 and two axles 3, 4.
- a cryocontainer 7, 8 is mounted on each side 5, 6 of the support frame 2 between the axles 3, 4.
- the cryogenic containers 7, 8 each store fluid 9, for example liquefied natural gas, which is also known to a person skilled in the art as LNG (“Liquid Natural Gas”).
- LNG Liquid Natural Gas
- the fluid 9 is in liquid form up to a level F, and above it in the gaseous state.
- the cryocontainers 7, 8 are used in connection with a motor vehicle, the stored fluid 9 can serve as fuel for an engine of the motor vehicle 1, for example. In other embodiments, however, the cryocontainers could also be provided in other areas of use.
- the lines connected to the cryogenic containers 7, 8 are referred to in technical terms as an ancillary system.
- an ancillary system for filling and venting the first cryocontainer 7 and the second cryocontainer 8 will be discussed in detail.
- FIG. 2 shows an ancillary system 10 known from the prior art for filling and venting two cryogenic containers 7, 8.
- the ancillary system 10 is divided into a filling system 11 and an independent venting system 12.
- the filling system 11 has a first filling line 13, which is led into the first cryogenic container 7, and a second filling line 14, which is led into the second cryogenic container 8.
- the first filling line 13 has a first filling coupling 15 which is accessible on the first side 5 of the motor vehicle 1
- the second filling line 14 has a second filling coupling 16 which is accessible on the second side 6 of the motor vehicle 1.
- cryogenic containers 7, 8 can be filled at the same time through only one of the two filling couplings 15, 16, the filling lines 13, 14 are connected by means of a first connecting line 17.
- the ventilation system 12 has a first vent line 18, which is led into the first cryocontainer 7, and a second vent line 19, which is led into the second cryocontainer 8.
- the first vent line 18 has a first vent coupling 20 which is accessible on the first side 5 of the motor vehicle 1
- the second vent line 19 has a second vent coupling 21 which is accessible on the second side 6 of the motor vehicle 1. So that both cryocontainers 7, 8 simultaneously through only one of the two vent couplings 20, 21 can be vented, the vent lines 18, 19 are connected by means of a second connecting line 22.
- a shut-off valve 25, which is accessible on the side 5, 6 of the respective valve coupling 19, 20, can also be provided in the respective valve line 18, 19.
- the cryogenic containers 7, 8 can be vented via the valve coupling 20, 21.
- an overpressure valve 26 is provided in the respective valve line 18, 19 between the connection to the cryogenic container 7, 8 and the shut-off valve 25, wherein the overpressure valves 26 can be connected as shown.
- FIG. 3 shows an ancillary system 27 for filling and venting the cryocontainers 7, 8 according to the invention. Accordingly, there are no separate filling and venting systems, each of which is routed separately into the cryocontainer by means of a line, but only a first connection line 28 is routed into the first cryocontainer 7 and a second connection line 29 is routed into the second cryocontainer 8.
- connection lines 28, 29 thus serve firstly to introduce fluid 9 into the respective cryogenic container 7, 8, and secondly to vent the respective cryogenic container 7, 8. Furthermore, according to the invention, there is only one connection line 30 between the two connection lines 28, 29.
- At least one filling coupling 31 and one vent coupling 32 are connected to the connecting line 30.
- the filling coupling 31 and the vent coupling 32 can both be accessible on one side 5, 6 of the motor vehicle 1, so that both cryocontainers 7,
- the connecting line 30 can be filled or vented by means of the connecting line 30. More generally, the filling coupling 31 and the vent coupling 32 could also be accessible on opposite sides 5, 6.
- a further filling coupling 33 and / or a further vent coupling 34 can be connected to the connecting line 30.
- the combination coupling shown further can be provided for filling and venting.
- a filling coupling 31, 33 and a vent coupling 32, 34 are preferably provided on each side 5, 6 so that the cryocontainers 7, 8 are refueled or vented from both sides 5, 6 of the motor vehicle 1 can be.
- a secondary system 27 is created in which both a filling coupling 31 and a vent coupling 32 (or a combination coupling) are connected to the same connecting line 30.
- the first cryocontainer 7, the second cryocontainer 8, the filling coupling 31 and the vent coupling 32 are thus connected to one another via a single pipe string.
- even two filling couplings 31, 33 and two vent couplings 32, 34 (or two combination couplings) are preferably connected to the same connecting line 30.
- a shut-off valve 35 is provided in the connection line 28 and a check valve 37 that opens in the filling direction is connected in parallel to the shut-off valve 35 by means of a branch line 36.
- the shut-off valve 35 is usually accessible in addition to the valve coupling 32 (or combination coupling). It can thereby be provided that the single connecting line 30 can also be used in conjunction with the shut-off valve 35 and the check valve 36.
- an embodiment in which the shut-off valve 35 is provided in the branch line 36 and the check valve 37 is provided in the connecting line 28 is the same as the solution mentioned above. This embodiment can in particular only be used for one cryocontainer 7, 8, as a result of which the connecting line 30 can also be omitted.
- connection line 28 is thus connected at one end to the cryocontainer 7 and opens at the other end into the filling coupling 31 and into the vent coupling 32 (or into the combination coupling), wherein in the connection line between the cryocontainer 7 and the filling coupling 31 or Vent coupling 32 (or in the combination coupling) the shut-off valve 35 is arranged with a check valve 37 connected in parallel.
