  • the connecting elements 15 for the gaseous and - if present - also the liquid media are provided in the front wall of the lower rail part.
  • each connecting element 15 has a pressure regulator 16 that can be set by hand and a pressure display instrument 17 added.
  • the electrical connections 13, 14 of the three groups are connected to electrical lines laid in the upper rail, which are inserted into the hollow body 11 from the ceiling via the pendulum arm 12a on the left in FIG.
  • connection elements 15 are provided in the connection device shown in Figure 1 for helium (He), nitrogen (N2), hydrogen (H2) and compressed air (Lu).
  • the supply lines for these gases also come from installation lines laid in the ceiling and are guided into the hollow body 11 through the right-hand pendulum arm 12c in FIG.
  • the combined connection device shown in FIG. 1 is equipped on its top with gas filter elements 18a for helium, gas filter elements 18b for nitrogen and gas filter elements 18c for hydrogen.
  • the line routing for the gaseous media to be supplied in this example is shown in FIG. 2.
  • the supply line 19d for compressed air guided through the pendulum arm or pendulum support 12c is connected directly to a pipeline 20d guided inside the lower rail. Since the gases helium, nitrogen and hydrogen in the present case are only of increased purity degrees are to be applied, the feed line 19a initially leads through the gas filters 18a. The outlet of the gas filters 18a is then connected to the pipeline 20a laid inside the lower rail 11b.
  • the feed line 19b for nitrogen leads to the pipeline 20b laid in the lower rail 11b and the feed line 19c for hydrogen via the gas filters 18c to the pipeline 20c laid in the lower rail.
  • a central distributor piece 21 is attached in the lower rail 11b for each of the three groups of connection elements 15, as will be explained in more detail below with reference to FIG. 3.
  • the hollow body forming the carrier for the connections is designed such that it is occupied with connection elements in practically the same grouping both on the front side visible in FIGS. 1 and 2 and on the rear side opposite to FIGS. 1 and 2 .
  • four rails can be provided, namely two upper rails 11a for electrical installation and two lower rails 11b for installation for gaseous and / or liquid media.
  • the pipes 20a, 20b, 20c and 20d can be installed in this space between the two lower rails 11b, as can the distributor elements 21.
  • each of these distributor elements 21 is equipped with a block-like distributor body 22, to which all four pipelines 20a, 20b, 20c and 20d provided in this example are connected.
  • each of the central distributor elements 21 has a block-like distributor body 22, through which all the pipelines 20a, 20b, 20c and 20d are passed.
  • - as Figure 4 shows - 22 passages 24 are formed in the distributor body.
  • These passage channels 24 can have a cross section such that the distributor body 21 can be plugged with these passage channels 24 over the continuous pipes 20a, 20b, 20c and 20d.
  • the annular gap formed between the outer surface of the pipelines 20a, 20b, 20c, 20d and the inner surface of the respective passage 24 is soldered or welded at 23 (FIG. 3).
  • the distributor body 22 is firmly seated in the framework of pipelines and is securely sealed off from each of the pipelines
  • connection bores 25 extending transversely to the passage channels 24, such that each transversely extending connection bore 25 passes through a passage channel 24 and thus one of the pipelines 20a, 20b, 20c and 20d (see FIG. 4).
  • these connection bores are equipped with an enlarged, internally threaded bore part 26, in which connection nipples 27 are to be fitted in a gas-tight or liquid-tight manner.
  • two connections are created on each central distributor element 21 for each through-channel 24 or each pipeline 20a, 20b, 20c and 20d.

  • a branch line 29 is attached to each of the connecting nipples 27.
  • these branch lines 29 each lead to pressure reducers 16 installed in the lower rail 11b.
  • Pressure display instruments for example pressure gauges 17, are connected to these pressure reducers 16.
  • each of the pressure reducers 16 is provided with a shut-off valve which can be actuated by actuating button 30, from which the actual connection element 15, to which the respective consumer is to be connected, is charged with the respective gaseous medium under the set pressure.
  • FIG. 4 shows that the pipeline framework can also contain more than four lines, depending on the number of gaseous media to be made available. Pipelines for liquid media can also be routed through the same distributor element 21 or the same distributor body 22. It is also possible to include pipelines for vacuum or suction lines in the pipeline framework and also to lead them through the same distributor element 21.
  • the distributor body 22 can be formed with recesses 31 which extend parallel to the passage channels 24. In this way, the weight and the heat capacity of the distributor body 22 are reduced. The latter is of particular importance if the pipelines 20a, 20b, 20c, 20d are to be drawn through the passage channels 24 of the distributor body 22 and to be soldered therein.
  • the diagram in FIG. 5 shows the possibility of using the second connections 28 on the distributor body 22 for expanded removal options to create the gaseous and liquid media. If, for example, one or the other gaseous or liquid medium is to be available both in a medium degree of purity and in a high degree of purity, in contrast to the embodiment according to FIG. 2, the feed lines 19a, 19b and 19c can also be connected directly to the pipelines 20a, 20b and 20c be connected.
  • the respective second branch line for example the second branch line 32a and second branch line 32c, is then led via a gas filter 18a or a gas filter 18c to a further pressure reducer 16a or 16c, so that a connection element 15 for medium is provided for the respective gaseous or liquid medium medium purity and a connection 15a or a connection 15c is available for the respective medium with a high degree of purity.
  • the use of the second connections 28 of the distributor element 21 could also be considered if one and the same gaseous or liquid medium with different pressure is required. In such a case, only a second pressure reducer is connected to the respective second connection 28, so that the user can remove the respective medium from one pressure and from the second pressure reducer with the other pressure.
  • Figure 6 shows an embodiment in which three rail-shaped hollow bodies 11 are arranged in a U-shape and on the upper rail 11a the electrical connections 13 and the lower rail 11b have the connections 15 for gaseous and liquid media as well as vacuum and suction line. Furthermore, the devices for pressure adjustment, for example pressure reducers 16, and the pressure display devices, for example pressure gauges 17, are also mounted in the lower rail 11b.
