Description
Elastischer DichtungsringElastic sealing ring
Die Erfindung betrifft einen elastischen Dichtungsring, wie er bei der gegenseitigen Abdichtung zwischen zueinander beweglichen Teilen benutzt wird.The invention relates to an elastic sealing ring, as it is in the mutual sealing between mutually movable Sharing is used.
lan kennt bereits die verschiedensten Querschnittsformen von solchen Dichtungen, wie beispielsweise Kolbenmanschetten, Nutringe mit Y-fö'rmigem Querschnitt oder sonstige Profilstangen. Alle diese Dichtungsmittel hatten den Nachteil, daß sie einen verhältnismäßig großen Reibungsverlust bedingen und dementsprechend leicht verschleißen, oder der Abdichtungsgrad ist ungenügend, wenn die Dichtung an den bewegten Flächen nicht mit dem genügenden Druck anliegen.lan already knows the most diverse cross-sectional shapes of such seals, such as piston sleeves, U-rings with a Y-shaped cross-section or other profile rods. All of these sealants had the disadvantage that they cause a relatively large loss of friction and accordingly wear easily or the degree of sealing is insufficient when the gasket to the Do not touch moving surfaces with sufficient pressure.

Durch die Erfindung werden die Mangel der bekannten Einrichtung behoben, indem bei einem Dichtungsring aus elastischem Material, welcher mit seinem äußeren oder inneren Umfang an einem von zwei zueinander beweglichen Teilen dichtend in radialer Richtung zur Anlage kommt, der Ring einen Hohlkörper bildet, der nach dem das Druckmittel aufnehmenden Raum offen ist. Das Druckmittel hat damit die Möglichkeit, in den inneren Raum des Ringes einzudringen und diesen aufzuweiten bzw. an die ihn umgebenden Tfendungen anzupressen.The invention eliminates the shortcomings of the known device fixed by a sealing ring made of elastic material, which with its outer or inner circumference comes to bear sealingly in the radial direction on one of two parts that can move relative to one another, the ring forms a hollow body which is open to the space receiving the pressure medium. The pressure medium has thus the possibility of penetrating into the inner space of the ring and expanding it or to the surrounding space To press down holes.
Vorzugsweise ist der hohle Ring in einer Hut, einer Ringkammer oder dergl. an einem der zueinander beviregten Teile untergebracht und diese Hut oder Kammer ebenfalls mit Öffnungen oder dergl. versehen, die nach dem Druckmittelraum durchgehen. Zur Erhöhung der radialen Ausdehnung oder Zusammenziehung des Ringmaterials, können erfindungsgemäß in den Ring Spreiz- oder Sehrumpfelemente, wie Federn oder dergl. eingesetzt sein.Preferably the hollow ring is in a hat, an annular chamber or the like. On one of the parts that are moved to one another housed and this hat or chamber also with openings or the like. Provided that after the pressure medium space go through. To increase the radial expansion or contraction of the ring material, according to the invention in the Ring expansion or very sump elements, such as springs or the like. be used.
Der Erfindungsgedanke läßt die verschiedensten Ausführungsmöglichkeiten zu, und zwar ist ein Schnitt durch zwei aneinandergleitende Teile wiedergegeben, die erfindungsgemäß gegeneinander abgedichtet sind.The idea of the invention allows a wide variety of possible designs, namely a section through two sliding against each other Parts shown that are sealed against each other according to the invention.
Das Gehäuse 1 bildet mit seinen Stirnflächen 2 und 3 beispielsweise den Teil eines Führungszylinders, in welchen ein Kolben 4 gleitet, der auf einem Kolbenrohr 5 sitzt. Durch den Eintritt 6 soll in den Zylinder 1 ein geeignetes Druckmittel (luft oder Flüssigkeit) in der Pfeilrichtung einströmen, so daß sich dessen Druck in der Kammer 7 auswirken und den Kolben 4 in der eingezeichneten Pfeilrichtung verschieben kann. Selbstverständlich kann auch die Betätigung des Kolbens von der anderen Seite her erfolgen, oder es gelangt ein doppelt wirkender Kolben zur Anwendung.The housing 1 forms with its end faces 2 and 3, for example the part of a guide cylinder in which a piston 4 slides, which is seated on a piston tube 5. A suitable pressure medium (air or liquid) should enter the cylinder 1 through the inlet 6 in the direction of the arrow flow in, so that its pressure in the chamber 7 and the piston 4 in the depicted Arrow direction can move. It goes without saying that the piston can also be actuated from the other side or a double-acting piston is used.
Für die Abdichtung sind am inneren Rand der Wandung 2 und am äußeren Rand des Kolbens 4 Kammern 8 bzw. 9 gebildet, in denen jeweils ein hohler elastischer Dichtungsring 10 bzw. 11 untergebracht ist. Der Innenraum 12 des elastischen Ringes 10 bzw. 11 hat seitliche Durchbrechungen 13 bzw. ist der Ring 10 oder 11 nach der Seite hin offen oder geschlitzt, Die Ringöffnung deckt sich mit seitlichen Durchbrechungen 14 in den Wandungen der Kammer 8 bzw. 9. Bei der Kolbendichtung 11 ist im Innern des Ringes noch eine Wurmfeder 15 eingelegt, die die radiale Ausdehnung des Dichtungsmaterials unterstützen soll.For the seal are on the inner edge of the wall 2 and formed on the outer edge of the piston 4 chambers 8 and 9, in each of which a hollow elastic sealing ring 10 or 11 is housed. The interior 12 of the elastic ring 10 or 11 has lateral openings 13 or is the ring 10 or 11 is open or slotted on the side, the ring opening coincides with lateral openings 14 in the walls of the chamber 8 and 9, respectively. The piston seal 11 also has a worm spring 15 inside the ring inserted, which is intended to support the radial expansion of the sealing material.
