Die erfindungsgemäße Verbindung kann allgemein zur Verbindung zweier Bauteile und der gleichzeitigen Herstellung einer fluidischen Verbindung zweier Fluidleitungen in den Bauteilen zweckmäßig sein. Die Linearführung kann anstatt durch einen Absatz, der in einer Aussparung geführt ist, auch durch eine Schwalbenschwanzführung oder eine andere übliche Führung gebildet sein. Das Modul 1 besteht insbesondere aus Kunststoff, wobei zweckmäßig die Zyklone 12 mit dem Grundkörper des Membranregelventils 14 und dem Flansch 2 sowie einem in Fig. 1 dargestellten Befestigungsflansch 34, in dem die Befestigungsöffnungen 28 ausgebildet sind, einteilig'ausgebildet sind. Die Ventilhaube 18 besteht insbesondere aus Aluminiumdruckguß. Auch andere Materialien können zweckmäßig sein. Durch die Bauteilverbindung kann eine beliebige Anzahl von Anschlüssen zwischen Fluidleitungen gleichzeitig hergestellt werden. Gegenüber einer Verbindung, bei der sowohl die erste als auch die zweite Fluidleitung an einer gemeinsamen Wand angeschlossen werden müssen, wird eine Dichtung eingespart.The connection according to the invention can generally be used for connection two components and the simultaneous production of one fluidic connection of two fluid lines in the components be appropriate. The linear guide can be replaced by a Heel that is guided in a recess, also through a Dovetail guide or other common guide formed his. Module 1 consists in particular of plastic, expediently the cyclones 12 with the base body of the diaphragm control valve 14 and the flange 2 and one in FIG. 1 illustrated mounting flange 34, in which the mounting holes 28 are formed in one piece are. The valve cover 18 consists in particular of die-cast aluminum. Other materials can also be useful. Any number of Connections between fluid lines made simultaneously become. Compared to a connection in which both the first as well as the second fluid line on a common wall one seal is saved.

Das in der ersten und der zweiten Fluidleitung strömende Fluid ist insbesondere ein Gas, die Bauteilverbindung kann jedoch auch bei einer in der Fluidleitung strömenden Flüssigkeit zum Einsatz kommen. Die die Mündungsöffnung umgebende Dichtung kann direkt am Umfang der Mündungsöffnung angeordnet sein, es kann jedoch auch vorteilhaft sein, die Dichtung mit radialem Abstand zur Mündungsöffnung anzuordnen.The one flowing in the first and second fluid lines Fluid is in particular a gas that can connect components however, also with a liquid flowing in the fluid line are used. The one surrounding the mouth opening Seal can be arranged directly on the circumference of the mouth opening be, but it can also be advantageous to use the seal radial distance to the mouth opening.
