 mitmachen können, da der Steg die Dehnung nur in dieser Richtung übertragen kann. Es findet daher bei jeder der besprochenen Ausführungsformen eine Dehnung des unteren Teiles bzw. Kolbenmantels in der Richtung der kleinen Achse und dadurch eine geringe Verkürzung in der Richtung der grossen Achse des elliptischen Querschnittes, d. h. eine Rundung des elliptischen Kolbenmantels statt, so dass in keinem Augenblick ein Verkeilen eintreten kann. 



   PATENT-ANSPRÜCHE :
1. Kolben für Verbrennungskraftmaschinen, dadurch gekennzeichnet, dass der an den Kolbenboden   anschliessende,   kreiszylindrische, die Dichtungsringe aufnehmende starkwandige Kolbenteil (a) mit dem führenden, im kalten Zustande einen elliptischen Querschnitt besitzenden und an der Zylinderwand nur an den beiden einander gegenüberliegenden Enden der grossen Ellipsenachse anliegenden, dünnwandigen und ungeschlitzten Kolbenmantel (d) derart zusammenhängt, dass die infolge der Erwärmung auftretende gleichmässige Ausdehnung des erstgenannten Kolbenteiles vom Kolbenmantel nur in der Richtung der kleinen Achse des elliptischen Querschnittes mitgemacht werden kann, wodurch gleichzeitig eine das
Verklemmen hindernde'Verkürzung des Mantels in der Richtung der grossen Achse des elliptischen Querschnittes eintritt.

 can participate, as the web can only transfer the stretch in this direction. In each of the embodiments discussed, there is therefore an expansion of the lower part or piston skirt in the direction of the minor axis and thus a slight shortening in the direction of the major axis of the elliptical cross section, i.e. H. a rounding of the elliptical piston skirt takes place, so that wedging cannot occur at any moment.



   PATENT CLAIMS:
1. Piston for internal combustion engines, characterized in that the circular cylindrical piston part (a) adjoining the piston head and receiving the sealing rings, with the leading, in the cold state, has an elliptical cross-section and on the cylinder wall only at the two opposite ends of the large Thin-walled and unslit piston skirt (d) adjacent to the elliptical axis is related in such a way that the uniform expansion of the first-mentioned piston part of the piston skirt that occurs as a result of the heating can only be made in the direction of the minor axis of the elliptical cross-section, whereby a
Jamming obstructive shortening of the jacket occurs in the direction of the major axis of the elliptical cross section.

Claims (1)

2. Kolben nach Anspruch 1, dadurch gekennzeichnet, dass zwischen seinem an den Kolbenboden anschliessenden Teil (a) und dem Mantel (d) Schlitze (f) vorgesehen sind, die beiderseits der durch die Achse der Kolbenzapfenlager (e) gehenden Kolbensymmetrieebene liegen. 2. Piston according to claim 1, characterized in that between its part (a) adjoining the piston head and the jacket (d) slots (f) are provided which lie on both sides of the piston plane of symmetry passing through the axis of the piston pin bearing (e). 3. Kolben nach den Ansprüchen 1 oder 2, gekennzeichnet, durch eine oder mehrere Rippen (g), die sich von dem an den Kolbenboden anschliessenden Kolbenteil (a) gegen die Kolbenzapfenlager (e) hin erstrecken und in der die Achse dieser Lager enthaltenden Kolbensymmetrieebene liegen. EMI2.2 3. Piston according to claims 1 or 2, characterized by one or more ribs (g) which extend from the piston part (a) adjoining the piston head towards the piston journal bearing (e) and in the piston plane of symmetry containing the axis of this bearing lie.
