Description

Kolbenring. Die vorliegende Erfindung hat eine Verbesserung des durch das Patent 389844 geschützten Kolbenringes zum Gegenstand und besteht darin, daß als Baustoff der Ringe hartgewalztes Kupferblech gewählt ist. Kupfer zeichnet sich vor allen anderen für die Herstellung von Kolbenringen in Betracht kommenden Metallen dadurch aus, daß es die größte Leitfähigkeit für Wärme aufweist und sich deswegen als Baustoff für Kolbenringe an erster Stelle eignet. Das hohe spezifische Gewicht des Kupfers sowie seine geringe Härte schließen jedoch seine Verwendung für Kolben aus. Dieser Nachteil fällt jedoch bei der Verwendung von Kupfer für nach dem Patent 389844 hergestellte Dichtungsringe weg, da die Ringe aus hartgewalztem und dünnem Kupferblech hergestellt sind. Das Gewicht der neuen Kolbenringe kann somit viel geringer gehalten werden als dasjenige der sonst üblichen Kolbenringe. Die aus Blech gestanzten Kolbenringe erweisen sich zwar als besonders vorteilhaft in Verbindung mit Leichtmetallkolben, können aber auch für eiserne Kolben wegen ihres geringen Gewichtes und hohen Wärmeleitfähigkeit allgemein Verwendung finden.Piston ring. The present invention has an improvement on this the patent 389844 protected piston ring to the subject and consists in that Hard-rolled copper sheet is selected as the building material of the rings. Copper stands out above all other metals suitable for the manufacture of piston rings characterized in that it has the greatest conductivity for heat and therefore Primarily suitable as a building material for piston rings. The high specific weight of copper as well as its low hardness, however, preclude its use for pistons the end. However, this disadvantage does not apply to the use of copper for the patent 389844 manufactured sealing rings, since the rings are made of hard-rolled and thin Copper sheet are made. The weight of the new piston rings can therefore be a lot are kept lower than that of the otherwise common piston rings. The ones made of sheet metal Stamped piston rings prove to be particularly advantageous in combination with light alloy pistons, but can also be used for iron pistons because of their small size Weight and high thermal conductivity are generally used.

Auf die besondere Ausgestaltung der Ringe kommt es in vorliegendem Falle nicht an. Sie können .die .in der Hauptpatentschrift dargestellten oder auch sonstige Formen aufweisen.The present case depends on the special design of the rings Don't fall. You can .die. Shown in the main patent specification or have other forms.
