Description

Kolben für Schwingkolben-Brennkraftmaschine Es sind bis jet:t die verschiedensten Arten von Schwingkolbenmotoren bekanntgeworden. Bei diesen Maschinen werden Kolben verwendet, die aus einem einzigen Metall bestehen und folgende Nachteile haben: Verwendet man ein festes Metall, z. B. Stahl, so wird der Kolben schwer und läßt sich nicht gut kühlen, da dieses Material die Wärme schlecht leitet. Verwendet man ein leichtes Metall, z. B. Aluminium, so wird der Kolben zwar leicht und gut kühlbar, jedoch wird er am Fuße leicht über seine Festigkeit beansprucht.Pistons for oscillating piston internal combustion engine Up to now: t die various types of oscillating piston engines have become known. With these machines For example, pistons made of a single metal are used and have the following disadvantages have: If you use a solid metal, e.g. B. steel, the piston is heavy and cannot be cooled well because this material is a poor conductor of heat. Used a light metal, e.g. B. aluminum, the piston is light and good coolable, but it is easily stressed on the foot due to its strength.

Die Erfindung betrifft nun einen Kolben, der gegenüber den bisherigen insofern Vorteile bietet, als er aus zwei verschiedenen Metallen aufgebaut ist, deren eines bei geringerer Festigkeit die Wärme gut leitet, während ihm das andere durch seine große Festigkeit die notwendige Stabilität verleiht.The invention now relates to a piston, which compared to the previous offers advantages in that it is made up of two different metals, one of which conducts heat well with a lower strength, while the other conducts heat well gives the necessary stability due to its great strength.

In den Abbildungen ist der Gegenstand der Erfindung an einigen Ausführungsbeispielen dargestellt.In the figures, the subject matter of the invention is based on some exemplary embodiments shown.

In Abb. i ist a der wärmeleitende Körper, b der Stützkörper, c der Kanal, durch den die Kühlflüssigkeit gepumpt wird, d eine Welle, auf der die zwei Flügelkolben sitzen. Der Kanal c läuft zuerst durch die an beiden Enden hohl gestaltete Welle d, dann rings an der äußeren Kante des Kolbens, an der die größte Erwärmung auftritt, und schließlich wieder durch das andere hohle Ende der Welle d in einen nicht mehr angegebenen Kühler. e ist ein Kanal, durch den Schmieröl an die Kolbenringe g geleitet wird. Die Trennung in der Welle erfolgt durch ein Rohr i. Durch die Pumpwirkung der Kolbenringe g wird das Schmieröl gleichmäßig über den ganzen Umfang des Kolbens verteilt.In Fig. I, a is the thermally conductive body, b is the supporting body, c is the Channel through which the cooling liquid is pumped, d a shaft on which the two Vane pistons sit. The channel c first runs through the hollow at both ends Wave d, then around the outer edge of the piston, where the greatest heating occurs, and finally again through the other hollow end of the shaft d into a no longer specified cooler. e is a channel through which lubricating oil reaches the piston rings g is directed. The separation in the shaft is done by a tube i. By the pumping action the piston rings g the lubricating oil evenly over the entire circumference of the piston distributed.

In Abb. z ist ebenfalls a der wärmeleitende Körper, b der Stützkörper, c der Kanal, durch den die Kühlflüssigkeit gepumpt wird, d eine Welle, auf der die Kolbenflügel sitzen. Jedoch wird das Kühlmittel auf nur einer Seite sowohl zu- als auch abgeführt. Zu diesem Zweck wird in die Bohrung der Kolbenwelle eine Trennungswand h eingeführt, die die Bohrung in zvei Teile teilt.In Fig.z, a is also the heat-conducting body, b the supporting body, c the channel through which the cooling liquid is pumped, d a shaft on which the Seated piston wings. However, the coolant is both supplied and on only one side also discharged. For this purpose, a partition wall is placed in the bore of the piston shaft h, which divides the bore into two parts.

Die Abb. 3 und q. stellen zwei Querschnitte dar. In Abb.3 ist der tragende Körper b hohl ausgeführt und auf die Welle aufgeschrumpft. Er kommt im Augenblick der Zündung, mithin stärksten Erhitzung und größten Verdichtung, mit den Brenngasen nicht in Berührung, wie dies Abb.5 zeigt.Fig. 3 and q. represent two cross-sections. In Fig.3 is the carrying body b executed hollow and shrunk onto the shaft. He comes in Moment of ignition, therefore strongest heating and greatest compression, with not in contact with the fuel gases, as shown in Figure 5.

In Abb. q. ist der tragende Körper b durch einen Schlitz der Welle d gesteckt, kommt also mit den Brenngasen überhaupt nicht in Berührung.In Fig.q. is the supporting body b through a slot of the shaft d, so does not come into contact with the fuel gases at all.
