Hier Abhilfe zu schaffen ist Aufgabe der vorliegenden Erfindung.Here To remedy this is the object of the present invention.
Gelöst wird die Aufgabe durch eine Ausführung der Halterung des Wandteils nach den Merkmalen des Patentanspruches 1. Weitere zweckmäßige Ausgestaltungen nach der Erfindung sind in den Unteransprüchen enthalten.Is solved the task through an execution the holder of the wall part according to the features of claim 1. Further expedient embodiments according to the invention are contained in the subclaims.
Die Erfindung wird nachfolgend anhand zweier in den Zeichnungen dargestellter Ausführungsbeispiele näher erläutert. Es zeigenThe Invention will now be described with reference to two in the drawings embodiments explained in more detail. It demonstrate
Ein
Gelenkkolben besteht aus einem Kopfteil
