Description

Abdichtungsvorrichtung für Drehkolbenmaschinen mit exzentrisch gelagertem Läufer Die Erfindung betrifft eine Abdichtungsvorrichtung für Drehkolbenmaschinen mit exzentrisch angeordnetem Läufer, der seitlich gegen das Gehäuse mittels durch Federn angedrückter Dichtungsleisten abgedichtet ist. Das Neue besteht darin, daß die inneren Enden der Dichtungsleisten derart untereinander verbunden sind, daß sie die Treibwelle umgeben und abdichten, und daß die äußeren Enden derselben gegen Leisten, die zur Abdichtung der Kolben dienen, anliegen, so daß eine vollkommene Abdichtung erzielt- wird.Sealing device for rotary piston machines with eccentrically mounted Rotor The invention relates to a sealing device for rotary piston machines with an eccentrically arranged rotor, which by means of the side against the housing Springs pressed sealing strips is sealed. The new thing is that the inner ends of the sealing strips are interconnected in such a way that they surround and seal the drive shaft, and that the outer ends of the same against Bars, which are used to seal the piston, rest, so that a perfect Sealing is achieved.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung eine Drehkolbenpumpe dargestellt, deren Gehäuse durch einen senkrechten Schnitt und deren Läufer mit den Kolben in Ansicht und nur zum Teil im Schnitt veranschaulicht sind.In the drawing, a rotary lobe pump is an embodiment of the invention shown, their housing through a vertical section and their runner with the piston are illustrated in view and only partially in section.

z ist das Gehäuse der Pumpe, in deren zylindrischer Wand 6 der Zulaufkanal 2 und ein Ablaufkanal 3 angeordnet sind. Im Innern des Gehäuses ist an den Seitenwänden 5 des Pumpengehäuses der Läufer exzentrisch gelagert, an dessen auf der Treibwelle q. befestigter Nabe 7 die Arme 8 sitzen. In deren Köpfen g befinden sich Löcher für Zapfen io, um die die Arme i i für die Kolben sich drehen. Die -Kolben besitzen an ihren äußeren Enden zylindrische Flächen 12, die an den Seiten Verbreiterungen 13 aufweisen. Die zylindrische Fläche 12 ist zur Innenwand des Gehäuses hin zu einer Walze 14 ausgebildet, um die sich ein Gleitschuh 15 derart dreht, daß seine Außenfläche die verschiedenen Druckräume voneinander dauernd vollkommen gegen die Zylinderwand des Pumpengehäuses abdichtet. Der Gleitschuh liegt fest an den Seitenwänden 5 des Pumpengehäuses an. Die Verbreiterung 13 und die Arme 8 sind mit Nuten für Dichtungsleisten 17 bzw. 16 versehen, die mit Hilfe von Federn gegen die Seitenwände 5 gedrückt werden.z is the housing of the pump, in whose cylindrical wall 6 the inlet channel 2 and a drain channel 3 are arranged. Inside the case is on the side walls 5 of the pump housing of the rotor eccentrically mounted on its on the drive shaft q. attached hub 7 the arms 8 sit. There are holes in their heads g for pins io around which the arms i i for the pistons rotate. Own the piston at their outer ends cylindrical surfaces 12, which are widened on the sides 13 have. The cylindrical surface 12 is towards the inner wall of the housing towards a Roller 14 is formed around which a sliding shoe 15 rotates so that its outer surface the different pressure chambers from each other permanently completely against the cylinder wall the pump housing seals. The sliding shoe rests firmly on the side walls 5 of the Pump housing. The widening 13 and the arms 8 are provided with grooves for sealing strips 17 and 16, respectively, which are pressed against the side walls 5 with the aid of springs.

Die Dichtungsleisten 16 stoßen mit ihren äußersten Enden gegen Dichtungsleisten ig, die gegen die zylindrische Fläche 12 der Kolben abdichten, und an ihrem inneren Ende gegeneinander, so daß die Welle q. und mithin das Lager des Läufers gegen die Druckräume hin abgedichtet ist.The sealing strips 16 abut with their outermost ends against sealing strips ig, which seal against the cylindrical surface 12 of the piston, and on its interior End against each other so that the shaft q. and therefore the runner's bearing against the Pressure chambers is sealed off.
