  Kolben für Verbrennungskraftmaschinen   mit Luft-oder Gemischkühlung.   



   Bei den bekannten Luft- oder Gemischkühlungen der Kolben von Verbrennungskraft-   maschinen ist keine geeignete Ableitungsvonichtung zur Überführung der Wärme an die Luft vorhanden. Bei diesen Kolben fliesst der Hauptteil der vom Kolben aufgenommenen Wärme   durch das Material nach dem den Kolben führenden   zylindrischen Kolbenschaft, während   an die durch den Kolben strömende Kühlluft nur ein geringer Teil der Wärme gelangt.

   Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.   fui",. 1   und 2 zeigen zwei Längsschnitte nach zwei im Winkel von 90  sich schneidenden Ebenen.

    Der Kolbenboden b, der möglichst dünnwandig ausgeführt ist, wird von den wärme- @@@@ den und wärmeabgebenden Stützen c getragen. Die Stützen c sird (vgl.

  Pistons for internal combustion engines with air or mixture cooling.



   In the known air or mixture cooling of the pistons of internal combustion engines, there is no suitable discharge device for transferring the heat to the air. In these pistons, the main part of the heat absorbed by the piston flows through the material to the cylindrical piston shaft guiding the piston, while only a small part of the heat reaches the cooling air flowing through the piston.
 EMI1.1
 



   An exemplary embodiment of the subject matter of the invention is shown in the drawing. fui ",. 1 and 2 show two longitudinal sections after two planes intersecting at an angle of 90.



  3 shows a cross section.



    The piston crown b, which is made as thin-walled as possible, is supported by the heat- @@@@ the and heat-emitting supports c. The supports c sird (cf. Fig. 3) are corrugated, which, due to their shape and low thickness, have a very large surface for the transfer of heat to the cooling air flow and also have a high buckling strength. The corrugated sheets and also sheets with crossbars are therefore particularly suitable as supports for the
