KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der Erfindung ist eine Verbindung für gegeneinander in Drehung befindliche Rohre, in denen Flüssigkeiten oder Gase fortgeleitet werden. Das Kennzeichen der Erfindung besteht darin, daß die Flüssigkeit oder das Gas in Form eines freien Strahles von dem unter dem höheren Druck stehenden Hohlkörper oder Rohr in den zweiten von niederem Druck tritt, dergestalt, daß anThe object of the invention is a connection for rotating against each other Pipes in which liquids or gases are transported. The characteristic of the invention is that the liquid or the gas in the form of a free jet from the one under the higher pressure standing hollow body or tube enters the second of low pressure, such that at
ίο der Trennungsstelle der gegeneinander in Drehung befindlichen Hohlkörper Stopfbüchsen und sonstige Dichtungen vermieden werden, wodurch die Reibungsarbeit bei der gegenseitigen Rotation auf ein Mindestmaß beschränkt wird.ίο the point of separation of each other in Rotating hollow bodies, stuffing boxes and other seals are avoided, whereby the frictional work in the mutual rotation is limited to a minimum will.
In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Zeichnung veranschaulicht, und zwar zeigt die Figur einen Längsschnitt.In the drawing, the subject matter of the invention is illustrated in an exemplary drawing, and that the figure shows a longitudinal section.
Der obere und untere . Hohlkörper befinden sich also in relativer Drehung zueinander. Sie sind demgemäß gegeneinander in Kugellagern gelagert.The upper and lower. Hollow bodies are therefore in relative rotation to one another. she are accordingly supported against each other in ball bearings.
Die Vorrichtung besteht, wie aus der Zeichnung ersichtlich, aus einem mit dem oberen Rohrende α fest verschraubten Teil, dessen Inneres nach Art einer Fangdüse ausgebildet ist. Vor der Mündung dieser Fangdüse endet das in eine Spritzdüse auslaufende untere Rohr, das vermittels Kugellager b mit dem oberen Rohr leicht drehbar verbunden ist, jedoch gegenüber dem Rohr α in achsialer Richtung nicht verschoben werden kann.As can be seen from the drawing, the device consists of a part which is firmly screwed to the upper end of the pipe α and whose interior is designed in the manner of a collecting nozzle. In front of the mouth of this catching nozzle ends the lower tube which runs out into a spray nozzle and which is easily rotatably connected to the upper tube by means of ball bearings b , but cannot be displaced axially relative to the tube α.
Die in der angegebenen Pfeilrichtung fließende Flüssigkeit tritt infolge ihres Überdruckes durch die Spritzdüse des unteren Rohres in Form eines vollkommen freien Strahles aus, der von der Fangdüse des oberen Rohres voll aufgefangen wird, derart, daß die Flüssigkeit ohne Unterbrechung durch die Trennungsstelle der beiden Rohre durchströmt.The liquid flowing in the direction of the arrow occurs as a result of its excess pressure through the spray nozzle of the lower pipe in the form of a completely free jet, which is fully caught by the nozzle of the upper pipe, so that the liquid flows through without interruption through the point of separation of the two pipes.
Die Spritz- und Fangdüsen wirken ganz ähnlich wie ein Strahlapparat, d. h. sie saugen Luft an der Trennungsstelle der beiden Rohre an. Es muß nun Vorsorge getroffen werden, daß an dieser Stelle keine Luftleere entsteht, da sonst das Schmieröl des Kugellagers mit in das Gehäuse hineingerissen würde. Zu diesem Zwecke ist in dem einen Teil b der Vorrichtung eine Bohrung c angeordnet, durch welche die äußere Luft ungehindert nachströmen kann.The spray and catch nozzles act in a very similar way to a jet device, ie they suck in air at the point of separation of the two pipes. Care must now be taken that there is no air void at this point, as otherwise the lubricating oil of the ball bearing would be torn into the housing. For this purpose, a bore c is arranged in one part b of the device, through which the external air can flow in unhindered.
