  • Combinations of the type specified at the outset are used in various fields of technology; one area in which such combinations are widely used is automotive engineering. With these combinations, the aim should be to be able to carry out the installation as easily and simply as possible, but at the same time to ensure that the connection is permanently and reliably sealed.
  • Commonly known and therefore known are flange connections with flat connection flanges which are interposed by one or more in their Form specially adapted seals are sealed and braced against each other by means of several screws.
  • Another combination of the type mentioned is known from DE 195 39 918 Cl. This document describes a liquid filter, in particular for oil or fuel of an internal combustion engine, and a matching filter connection flange which forms part of the internal combustion engine.
  • the sealing surfaces on the filter connection flange of the internal combustion engine are radial sealing surfaces that are concentric with one another and that the seals on the filter housing are radial seals that are concentric with one another.
  • the object of the present invention is therefore to create a combination of the type mentioned at the outset which avoids the disadvantages set out and with which, in particular, a flange connection is easy to produce, in which a permanent and reliable tightness of the connection is guaranteed and in which, in particular, the add-on functional unit is made from plastic or from a metal of lower stability instead of a stable metal without sacrificing its functional reliability and durability can be.
  • connection state also comprises at least one radial seal arranged between the pipe socket and the associated pipe bore.
  • the combination according to the invention advantageously offers simple manufacture of the connection, namely by simply plugging it together.
  • the manufacture of the individual flange connecting elements is also technically simple, since on the one hand only bores have to be made and on the other hand only pipe sockets are provided, which are expediently all identical in order to simplify their manufacture.
  • the liquid or gas pressures that occur during operation of the combination only have a very slight effect on the quality and durability of the connection and its tightness in the combination according to the invention, because correspondingly lower loads occur due to the smaller surfaces of the flange connection that are subjected to pressure during operation.
  • By using the radial seals in all connections their tightness does not depend on the applied axial forces.
  • the end wall has one or more openings for the passage of mechanical connecting means, preferably screws, which can be releasably engaged with the main unit.
  • the line bores and / or the line stubs each have a groove or step for receiving or engaging the radial seal.
  • the radial seals are preferably standard O-rings, whereby only very low costs have to be expended for each individual radial seal. Specially shaped seals are not required here.
  • a further development of the invention provides that in addition to a first add-on functional unit, preferably an oil or fuel filter, a second add-on functional unit, preferably an oil cooler or fuel preheater, is provided which has flange connecting elements designed and arranged in two separate areas that the second add-on functional unit can be inserted between the main unit and the first add-on functional unit as required.

  • the flange connection elements provided for this purpose of the first add-on functional unit can simply be closed; If necessary, the second add-on functional unit can also be retrofitted after removing the locks.
  • the second add-on functional unit comprises at least one support and fastening element which is arranged at a distance from its flange connection elements and which is by means of releasable connecting means , preferably screws, can be mechanically connected to the main unit or to the first add-on functional unit.
