  • To the another is a pressure and flow-tight seal the connection for the supply and discharge line reached. The flow connection between the feed or discharge line and an associated flow path within the filter housing via each other corresponding flow openings both on Connecting flange as well as in the wall of the filter housing, these flow openings being from the respective ones Contact surfaces on the outside of the filter housing or enclosed on the connection flange. After welding the corresponding contact surfaces on the filter housing or at the connection flange are the aligned flow openings closed to the outside pressure and flow tight. Additional sealing measures, such as sealing rings or the like, are not required.
  • According to one advantageous embodiment, the welding takes place the contact surfaces by way of infrared welding. Here the involved welding surfaces, So the contact surfaces on the filter housing and on Connection flange, at the same time via infrared rays so far heated until the welding temperature is achieved. Subsequently, the contact surfaces on each other placed (mirror welding). Infrared welding has the advantage that it saves space can and no additional tools for the Performing the welding process requires. Furthermore It can be done gently, so that a material Damage to the filter housing or the connection flange not to be expected in a version in plastic is.
  • The contact surface on each component-that is to say both on the filter housing and on the connection flange-has at least one closed contact loop with a circumferential contact path which encloses at least one connection for the supply or discharge line. Advantageously, however, at least two such contact loops, for example, three contact loops vorgese hen that touch each other or share a contact path in sections, which is part of the contact loop. In this way, two or more closed loops are obtained, which for example enclose a round or angular area in each case, the enclosed area being separated from the outside world in a flow-pressure-tight manner.
  • in the Traps of at least three contact loops are these expediently arranged in such a way that in each case two adjoining contact loops extend in different axial directions, so for example two of the three contact loops in the circumferential direction and one of these contact loops with a third contact loop in the axial direction. this makes possible it, relatively complex geometries with a plurality of enclosed and pressure-tight separated areas to realize. Within each enclosed area can a connection for a supply or discharge line are located.
  • Conveniently, the contact surfaces are flat, regardless of geometric shape of the filter housing. in principle but also curved contact surfaces are considered, As long as it is guaranteed that the contact surfaces on the filter housing and on the connection flange in corresponding Way are formed, so that the respective contact surfaces can be placed flush with each other for assembly.
  • Around To improve the assembly and also the tightness, it may be appropriate be, at least the contact loops of a contact surface as contact grooves with protruding side walls to provide, in the contact loop of the other component after Type of tongue and groove principle engages. Execution as a contact groove allows a positive interlocking the contact surfaces, creating the desired mounting position is achieved without further measures and aids.
  • When Material for the filter housing and the connection flange comes plastic, such as polyamide, especially polyamide 6 or polyamide 6.6 into consideration. This material is suitable in Advantageous for the infrared welding process.
