Description

Zum -Abdichten von Kolben sind verschiedenartige- Dichtungen bekannt.- Am meisten werden Nutringmanschetten mit Dichtlippen verwendet3 diesich durch den Flüssigkeitsdruck an_die_ Wandun-_ gen des Kolbens und Zylinders anpressen..-Solche Nutringmanschetten sind aber so wenig dehnbar, daß-z.-B. der Durchmesser des Kolbenansatzes für die -Aufnahme der Manschette nicht größei :`als seine lichte Weite sein darf. Deshalb muß der Kolbenansatz bei kleinerem Durchmesser nachAufbringen der Manschette noch mit einer besonderen Sperrscheibe versehen werden, was für die Massenherstellung eine Komplizierung bedeutet: Weiterhin sind einfache Kolbendichtungen bekannt, die aus einem dünnen metallischen Ringträger in der Höhe der ganzen Kolbennut mit einer nach außen hervortretenden Mittelrippe bestehen, um die herum ein parallel zu seiner Stirnfläche aufgeschnittener Ring gelegt ist. Bei diesen-Dichtungen ist-jedoch die Rippe oder der Ring, welcher in der Schnittfuge liegt, in der Querrichtung nicht frei verschiebbar, da der starre Ringträgerrücken seine Beweglichkeit begrenzt. Der Einlagering kann also nicht unabhängig von dem geteilten Ring arbeiten.Various types of seals are known for sealing pistons. U-ring collars with sealing lips are mostly used3 that are Press the fluid pressure against the walls of the piston and cylinder U-ring seals are so little stretchable that-z.-B. the diameter of the base of the piston for the absorption of the cuff not greater than its clear width. Therefore, if the diameter of the piston is smaller, it must be used after the sleeve has been applied can still be provided with a special locking washer, which is suitable for mass production a complication means: Furthermore, simple piston seals are known which from a thin metallic ring carrier at the level of the entire piston groove with a outwardly protruding central rib, around which a parallel to his End face cut ring is placed. With these seals, however, the Rib or the ring which lies in the kerf, not in the transverse direction freely movable, as the rigid ring carrier back limits its mobility. The insert ring cannot work independently of the split ring.

Demgegenüber wird erfindungsgemäß eine .ganz einfache Kolbenabdichtung vorgeschlagen, die auf billigstem Wege hergestellt werden kann, ohne die Güte der Dichtung zu beeinflussen. In den Kolben oder auch in den Zylinder wird eine Nut eingefräst, in die zwei einfache Bunaringe nebeneinander eingelegt und lest eingewalzt oder angedrückt werden. Diese beiden Rippen werden nun nach ihrenAußenseiten in eine im Kolben oder Zylinder dafür angeordnete Ausnehmung umgelegt und dichten damit den Zylinder nach beiden Seiten hin ab. Muß nur nach einer Seite hin abgedichtet -werden, so. genügt ein nach dieser Seite umgelegter 'Bunaring.In contrast, a very simple piston seal is provided according to the invention proposed that can be produced in the cheapest way without compromising the quality of the Affecting poetry. There is a groove in the piston or in the cylinder milled into the two simple buna rings placed next to each other and read rolled or pressed on. These two ribs are now on their outside in a recess arranged in the piston or cylinder for this purpose is folded over and sealed with it the cylinder off on both sides. Only has to be sealed on one side -be so. All that is needed is a 'bunaring' turned to this side.

In den Abbildungen ist ein Beispiel des Erfindergedankens wiedergegeben.An example of the inventive concept is shown in the figures.

Abb. z zeigt den Kolben z mit den in die gefräste Nüt ': eingewalzten oder angedrückten Buna-.Scheiben 3 und q..Fig. Z shows the piston z with the grooves rolled into the milled groove or pressed on Buna discs 3 and q ..

In Abb. a sind die Bunascheiben 3 und 4 in die Ausnehmungen-- des Kolbens r umgebogen. Der Kolben i läuft in dem Zylinder 6. Ebenso wie in dem Kolben können die Bunascheiben auch in eine eingefräste Nut des Zylinders eingewalzt oder angedrückt werden, ivie das aus Abb. 3 zu ersehen ist.In Fig. A, the bunas 3 and 4 are in the recesses - des The piston r bent over. The piston i runs in the cylinder 6. Just as in the piston the Buna disks can also be rolled or rolled into a milled groove in the cylinder be pressed, ivie that can be seen from Fig. 3.
