Description

  

   <Desc/Clms Page number 1> 
   lingeküblter   Kolben für Verbrennungskraftmaschinen. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Für die Erfindung ist wesentlich, dass der mittlere Teil des Bodens mit kühleren Teilen des Mantels verbunden ist, und dass sich der Boden infolge seiner Trennung vom Mantel möglichst frei auszudehnen vermag. Hiedurch erfährt der Boden nicht nur eine äusserst wirksame Kühlung, sondern es werden auch die im Boden auftretenden Temperaturspannungen nach Möglichkeit herabgemindert. 



   PATENT-ANSPRÜCHE :
1. Ungekühlter Kolben für Verbrennungskraftmaschinen mit senkrecht zur Kolbenachse unterteiltem Kolbenmantel, dadurch gekennzeichnet, dass der mittlere, sich besonders stark erwärmende Teil des mit dem oberen Teil des Kolbenmantels ein Stück bildenden Kolbenbodens   (a2)   mit dem unteren kühleren Teil (a4) des Kolbenmantels durch einen zweckmässig kegelförmig gestalteten, den Arbeitsdruck übertragenden Kolbeninnenkörper   (a3)   verbunden ist, der so bemessen ist, dass er die sich im Kolbenboden stauende Wärme mit Sicherheit in den unteren Teil des Kolbenmantels überzuleiten vermag.

   Linged piston for internal combustion engines.
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   It is essential for the invention that the middle part of the base is connected to cooler parts of the jacket and that the base is able to expand as freely as possible as a result of its separation from the jacket. This not only provides the floor with extremely effective cooling, but also reduces the temperature stresses that occur in the floor as far as possible.



   PATENT CLAIMS:
1. Uncooled piston for internal combustion engines with a piston skirt divided perpendicularly to the piston axis, characterized in that the middle, particularly strongly heating part of the piston head (a2), which forms a piece with the upper part of the piston skirt, passes through with the lower, cooler part (a4) of the piston skirt an appropriately conical design, the working pressure transmitting piston inner body (a3) is connected, which is dimensioned so that it is able to transfer the heat accumulating in the piston crown with certainty into the lower part of the piston skirt.

Claims (1)

2. Kolben nach Anspruch 1, dessen Lücke zwischen den beiden Mantelteilen durch einen Ring verschlossen ist, dadurch gekennzeichnet, dass sich der Ring (B) an die Zylinderwand und an die Mantelteile des Kolbens gleichmässig anschmiegt, gegebenenfalls zur Aufnahme von weiteren Kolbenringen benutzt werden kann und zur Überleitung eines Teiles der sich im Kolbenboden stauenden Wärme in den unteren kühleren Teil des Kolbenmantels dient. 2. Piston according to claim 1, the gap between the two shell parts is closed by a ring, characterized in that the ring (B) hugs the cylinder wall and the shell parts of the piston evenly, optionally can be used to accommodate further piston rings and serves to transfer part of the heat accumulated in the piston crown to the lower, cooler part of the piston skirt. 3. Kolben nach Anspruch 1, dadurch gekennzeichnet, dass der Kolbenboden mit dem kegelförmig gestalteten Kolbeninnenkörper lösbar verbunden ist. EMI2.1 3. Piston according to claim 1, characterized in that the piston head is detachably connected to the conical inner piston body. EMI2.1
