Abstract
Description
Die Erfindung betrifft ein Verbindungselement für ein Rohrsystem aus wenigstens zwei etwa koaxialen Leitungsrohren, von denen ein Leitungsrohr zum Führen eines Strömungsmediums – insbesondere eines gasartigen Strömungsmediums – ausgebildet sowie von einem Außenrohr größeren Durchmessers umgeben und in diesem koaxial durch das im Innenraum des Außenrohres etwa radial verlaufende draht- oder stabförmige Verbindungselement festgelegt ist nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a connecting element for a pipe system of at least two approximately coaxial conduits, one of which is a conduit for To lead a flow medium - in particular a gaseous flow medium - formed as well as an outer tube larger diameter surrounded and in this coaxially by the inside of the outer tube set about radially extending wire or rod-shaped connection element is according to the preamble of claim 1.

offenbart die
In Kenntnis dieser Gegebenheiten hat sich der Erfinder das Ziel gesetzt, ein derartiges Rohrsystem dadurch zu verbessern, dass die zwischen den koaxialen Rohren gespannten Verbindungselemente sowohl eine Anpassung an die Rohre sowie deren koaxiale Ausrichtung ermöglichen als auch einen Festverbund zwischen den Rohren.In Knowing these facts, the inventor set himself the goal To improve such a pipe system in that the between the coaxial pipes tensioned fasteners both a Allow adjustment to the tubes and their coaxial alignment as well as a permanent bond between the pipes.
Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an. Zudem fallen in den Rahmen der Erfindung alle Kombinationen aus zumindest zwei der in der Beschreibung, der Zeichnung und/oder den Ansprüchen offenbarten Merkmale.to solution performs this task the teaching of the independent claim; to give the dependent claims favorable Further education. In addition, all fall within the scope of the invention Combinations of at least two in the description, the drawing and / or the claims disclosed features.
Erfindungsgemäß sind die beiden Enden des Drahtstückes einander in Abstand benachbart. Das Verbindungselement weist zudem beidseits einer durch die Lage seiner Enden bestimmten Symmetriegeraden zumindest jeweils einen dem Innenrohr zugeordneten inneren Knickbereich auf, von dem jeweils zwei – in einem Winkel zueinander stehende – Schenkelabschnitte ausgehen; von denen ist zumindest einer an einen teilkreisförmig gebundenen Abschnitt angeschlossen, welcher dem Außenrohr innenseitig anliegt.According to the invention both ends of the piece of wire adjacent each other at a distance. The connecting element also has on both sides of a symmetry thread determined by the position of its ends at least in each case an inner bend region assigned to the inner tube of which two each - in an angle to each other - go out leg sections; of which at least one is bound to a part-circular Connected section which rests on the inside of the outer tube.
Auch liegt es im Rahmen der Erfindung, dass sich der erwähnte Winkel zur Außenseite des Verbindungselementes öff net und an den einen der Schenkelabschnitte in einem inneren Winkel ein Winkelschenkel anschließt, der als Endab schnitt des Verbindungselementes mit seiner Stirnfläche der Symmetriegeraden zugeordnet ist. So entstehen erfindungsgemäß drei gleichmäßig um die Kreiskontur verteilte innere Knickbereiche, die dem Innenrohr zugeordnet werden.Also it is within the scope of the invention that the mentioned angle to the outside of the connecting element öff net and to one of the leg portions at an inner angle an angle leg connects, the cut as Endab of the connecting element with its end face of Symmetry shop is assigned. Thus, according to the invention three evenly around the Circle contour distributed inner kink areas, which are assigned to the inner tube become.
Von diesen liegt im übrigen ein innerer Knickbereich des Verbindungselementes in der genannten Symmetriegeraden. Letztere ist durch den Mittelpunkt einer Kreiskontur gelegt, welcher dem Innenrohr zugeordnete Knickbereiche des Verbindungselementes benachbart sind; diese Kreiskontur bestimmt der Querschnitt des Innenrohres.From this is the rest an inner kink region of the connecting element in said symmetrical thread. The latter is placed through the center of a circular contour, which the inner tube associated kink areas of the connecting element are adjacent; this circular contour determines the cross section of the Inner tube.
Von erfindungsgemäßer Bedeutung ist auch die Größe der Winkel am Verbindungselement; der äußere Winkel liegt zwischen 115° und 120°, der innere Winkel bei 105°.From meaning according to the invention is also the size of the angles on the connecting element; the outer angle is between 115 ° and 120 °, the inner angle at 105 °.
Das erfindungsgemäße Verbindungselement zeichnet sich durch drei dem Außenrohr anliegende Verbindungsbereiche aus, die jeweils durch zwei der äußeren Knickbereiche des Verbindungselements begrenzt sind. Zudem greift das Verbindungselement vorteilhafterweise sowohl im Außenrohr als auch im Innenrohr in einen von einer ringförmigen Ausformung gebildeten Rinnenraum bzw. in eine Einformung ein; zwischen deren Innenflächen wird das Verbindungselement gehalten.The connecting element according to the invention is characterized by three connecting regions which bear against the outer tube and which are each delimited by two of the outer bending regions of the connecting element. In addition, the connecting element advantageously engages both in the outer tube and in the Inner tube in a groove formed by an annular formation groove or in a molding; between the inner surfaces of the connecting element is held.
Der Querschnitt jener ringartigen Einformung des Innenrohres entspricht bevorzugt etwa dem halben Querschnitt des Verbindungselementes. Der Rinnenraum des Außenrohres liegt in Einbaustellung in einer von der Einformung des Innenrohres bestimmten Radialebene und ist im Querschnitt gegensinnig zur Einformung gekrümmt.Of the Cross section corresponds to that ring-like indentation of the inner tube preferably about half the cross section of the connecting element. The gutter of the outer tube is in the installed position in one of the indentation of the inner tube certain radial plane and is in cross-section opposite to the indentation curved.
Insgesamt ergibt sich ein die vom Erfinder gesehene Aufgabe in bestechender Weise lösendes Rohrsystem.All in all results in a task seen by the inventor in captivating Way-releasing pipe system.
