Description

Naschine mit sichelförmigem Arbeitsraum und Dichtringen mit unterbrochenen Dichtflächen Um die Wirtschaftlichkeit und den einwandfreien Betrieb von Maschinen mit sichelförmigern Arbeitsraum zu sichern, ist die Abdichtun des Arbeitsraumes von -rößter Bedeu-9 ti tung. Um dieses Ziel zu erreichen, werden fast allgemein Dichtringe und Dichtleisten angeordnet, die so angeordnet sind,* daß ein Austreten des Betriebsmittels aus dem Arbetsraum verhindert wird. In zahlreichen. Fällen bedingt aber der Aufbau der Maschinen, daß der Dichtring unterbrochen wird, daß also keine geschlossene Dichtfläche vorhanden ist. Die dann entstehenden Fugen und Spalten sind aber sehr schwer abzudichten.Machine with sickle-shaped work space and sealing rings with interrupted ones Sealing surfaces About the economy and the perfect operation of machines To secure with a sickle-shaped work area is the sealing of the work area of utmost importance. To achieve this goal will be almost general Sealing rings and sealing strips arranged, which are arranged so * that leakage of the equipment from the work room is prevented. In numerous. Cases conditional but the structure of the machines, that the sealing ring is interrupted, so that none closed sealing surface is available. The resulting joints and gaps but are very difficult to seal.

Die vorliegende Erfindung umgeht übelstand dadurch, daß ein oder mehrere zusätzliche Dichtringe angeordnet werden, die die Unterbrechungen umgehen und so vollständig in sich geschlossene Dichtflächen aufweisen.The present invention obviates the disadvantage in that one or more additional sealing rings are arranged to bypass the interruptions and so have completely self-contained sealing surfaces.

In der Zeichnung ist die Erfindungan einer beispielsweise gewählten, im Querschnitt dargestellten Maschine gezeichnet. Dereinfache ren Darstellung wegen ist auch die Dichtflüche des feststehenden Hohlzylinders in die Bildebene gezeichnet.In the drawing, the invention is shown in an example chosen, Machine shown in cross section drawn. For the sake of simplicity of illustration the sealing surface of the stationary hollow cylinder is also drawn in the plane of the drawing.

a ist die in dem Gehäusef gelagerteWelle, auf deren exzentrischen. Teilb der Kolbenc drehbeweglich angeordnet ist. Mit dem Gehäuse / ist fest verbunden der zentrisch zur Welleff. liegende Hohlzylinderg, an dessen äußerem Umfang der Kolben c abrollt und mit ihm den sichelförmigen Arbeitsraurah 'bildet.. Der Kolbenc führt in diesem Falle nur eine exzenterförmige Bewegung aus, da ier durch das Gleitstücke verhindert wird, an der kreisenden Bewegung der Welle, teilzunehmen. In dem feststehenden Zylinder g ist das Widerlager i, das den Arbeitsraum unterteilt, vermittels des Ko ' pfes s gelenkig auf - gehängt und im Kolbein c durch die Nuß k geführt. Das im Arbeitsraum k befindliche Betriebsmittel wird durch die Dichtringe 1 im Kolben c bzw. m im Hohlzylinder g verhindert, ins Freie zu treten. Diese Ringe sind jedoch nicht in sich geschlossen, sondern sie werden durch die Nuß k bzw. den Kopfs des Widerlagers 1 unterbrochen. Diese Stoßfugen zwischen dem Dichtring 1 und der Nuß k bzw. Ring m und Kopf s sind schwer zu dichten- und geben daher zu Verlusten Veranlassung. Aus diesem Grunde wird im Kolben c ein zusätzlicher Dichtringn vorgesehen, der sowohl den Dichtring 1 als auch die Nuß k in geschlossenem Zuge umschließt und so eine ununterbrochene Dichtfläche schafft, die verhindert, daß das Betriebsmittel ün Gehäuse austritt. a is the shaft mounted in the housing, on the eccentric shaft. Part b of the piston c is rotatably arranged. The centric to the shaftff is firmly connected to the housing /. lying hollow cylinder, on the outer circumference of which the piston c rolls and forms with it the sickle-shaped working surface. G in the stationary cylinder is the abutment i, which divides the working space by means of the Ko 's PFEs articulated on - and hung in Kolbein c k out by the nut. The operating fluid located in the working space k is prevented from entering the open air by the sealing rings 1 in the piston c or m in the hollow cylinder g. However, these rings are not self-contained, but rather they are interrupted by the nut k or the head s of the abutment 1 . These butt joints between the sealing ring 1 and the nut k or ring m and head s are difficult to seal and therefore give rise to losses. For this reason, an additional sealing ring is provided in the piston c, which encloses both the sealing ring 1 and the nut k in a closed course and thus creates an uninterrupted sealing surface that prevents the operating fluid from leaking into the housing.

Im feststehenden Hohlzylinder wird ebenfalls ein in sich geschlossener Dichtring,o mit ununterbrochener Dichtflache angeordnet, dei das durch die Stoßfuge zwischen Dichtring m. und Widerlagkopf s noch austretende Betriebsmittel abfängt und verhindert, in der Richtung nach Wellea zu entweichen.A self-contained sealing ring, o with an uninterrupted sealing surface, is also arranged in the stationary hollow cylinder, which intercepts the operating material still escaping through the butt joint between the sealing ring m. And the abutment head s and prevents it from escaping in the direction of Wellea.
