Description

Im' Patent 863 429 würde ein Dichtungskörper für schiebergesteuerte Brennkraftmasch.inen beschrieben, der an der dem Verbrennungsraum zugewandten Seite des Schiebers- -allein - durch den Gasdruck angedrückt wird und aus einem Dichtungsteil mit Kolbenringen besteht. Das Kennzeiohen der Erfindung des Hauptpatents besteht darin, daß der Dichtungskörper aus zwei konzentrisch. ineinanderliegenden, durch einen Spalt getrennten und vorzugsweise am äußeren Ende miteinander verschweißten Ringen besteht, von denen. der innere den äußeren wegen den. Verbrennungsraum abdeckt. Nach einem weiteren Merkmal der Erfindung soll der Spalt zwischen den Ringen. zur Aufnahme eines Isoliermittels oder einer Luftschicht dienen.In 'Patent 863,429 a seal body for valve-controlled Brennkraftmasch.inen described on the side facing the combustion chamber of the slide - alone - is pressed by the gas pressure and from a sealing part with piston rings. The identification of the invention of the main patent exists in that the sealing body consists of two concentric. nested, through separated by a gap and preferably welded together at the outer end Wrestling consists of those. the inner because of the outer. Covers combustion chamber. According to a further feature of the invention, the gap between the rings. to the Serve uptake of an isolating agent or a layer of air.

Es hat sich nun herausgestellt, daß es besonders vorteilhaft ist, .das Isoliermittel an der Stelle.zwiscahen .den beiden Ringen anzuordnen, an der der innere Ring den äußeren. Ring gegenüber dem Verbrennungsraum abdeckt, und, in; Achsrichtung gesehen, den Spalt nicht mit einem Isoliermittel auszufüllen, sondern dort Luft bzw. einen mehr oder minder evakuierten Luftraum zu lassen. Hierdurch behält -der Dichtungsring auch im Dauerbetrieb seine Vorspannung und ein Verzundern tritt praktisch nicht mehr ein.It has now been found that it is particularly advantageous .to arrange the isolating agent at the point between .the two rings where the inner ring the outer. Ring covering opposite the combustion chamber, and, in; Seen in the axial direction, the gap should not be filled with an insulating agent, but to leave air or a more or less evacuated air space there. Through this -the sealing ring retains its preload and scaling even in continuous operation practically no longer occurs.

In der Zeichnung ist ein Dichtungsring gemäß der Erfindung veranschaulicht. Er besteht aus dem Innenring i und dem Außenring 2, in den Kolbenringe 3 eingesetzt werden. An der Stelle 4, an der der Innenring i den Außenring 2 gegenüber dem nicht .dargestellten Verbrennungsraum abdeckt, ist der Spalt zwischen den beiden Ringen durch ein Isoliermittel 5 verschlossen. In dem verbleibenden Spalt 6 befindet sich ein gasförmiges oder flüssiges Isoliermittel, oder der Spalt ist nahezu evakuiert.In the drawing, a sealing ring according to the invention is illustrated. It consists of the inner ring i and the outer ring 2, inserted into the piston rings 3 will. At the point 4 at which the inner ring i does not match the outer ring 2 with respect to the .Covers the combustion chamber shown, is the gap between the two rings closed by an insulating means 5. In the remaining gap 6 is located a gaseous or liquid insulating medium, or the gap is almost evacuated.
