Die Neuerung bezieht sich auf einen Kolben für Verbrennungsmaschiner?.The innovation refers to a piston for internal combustion engines?.
In den üblichen Verbrennungsrsaschiiieii treten erhebliehe Energieverluste durch die vom Kolbenkopf zum Kolbenrumpf und von dort "ir;s öl abgeführte Wärme auf.In conventional combustion chambers, significant energy losses occur due to the heat transferred from the piston head to the piston body and from there to the oil.
Der Neuerung liegt die Aufgabe zugrunde, diese Energieübertragung zu verhindern.The innovation is based on the task of preventing this energy transfer.
Zur Lösung dieser der Neuerung zugrundeliegenden Aufgabe wird ein Kolben vorgeschlagen, in dessen Kolbenkoof eine vorzugsweise unter Vakuum stehende Ausnehmung vorgesehen ist, die als Wärmeübertragungsdämmung dient.To solve this problem underlying the innovation, a piston is proposed in whose piston head a recess is provided, preferably under vacuum, which serves as heat transfer insulation.
Ein Ausführungsbeispiel der Neuerung wird nachfolgend anhand der Zeichnung erläutert.An example of the innovation is explained below using the drawing.
In der Zeichnung ist der obere Teil eines Kolbens im Schnitt gezeichnet und es ist ein Kolbenkopf 1 erkennbar sowie ein Kolbenrumpf 2. Im Kolbenkopf und Kolbenrumpf sind tei1 kugelförmige Ausnehmungen 3 und 4 vorgesehen, so daß bei zusammengesetztem Kolbenkopf 1 und Kolbenrumpf 2 eine linsenförmige Ausnehmung geschaffen wird, die unter Vakuum gesetzt werden kann. Die Verbindung der beiden Teile erfolgt im Randbereich, und zwar vorzugsweise unter Zwischenschaltung einer entsprechenden Dichtung 5, wobei die beiden Teile fest miteinander verklebt sein können.In the drawing, the upper part of a piston is shown in section and a piston head 1 can be seen as well as a piston body 2. Spherical recesses 3 and 4 are provided in the piston head and piston body, so that when the piston head 1 and piston body 2 are assembled, a lens-shaped recess is created that can be placed under vacuum. The connection of the two parts takes place in the edge area, preferably with the interposition of a corresponding seal 5, whereby the two parts can be firmly glued together.
