  Kolbenkühlung für Kraftmaschine. 



   Die Erfindung betrifft eine   Kolbenkühlung   für Kraftmaschine mittels eines Schmiermittels, das durch die hohle Kurbelwelle, Treibstange und Kurbelzapfen in den   Kühlraum   des Kolbens geleitet wird. 



   Die Erfindung besteht darin, dass ein Windkessel in die Zuleitung eingeschaltet ist, um den 
 EMI1.1 
 Schmieröl gleichzeitig zur Kühlung des Kolbenoberteils mitbenutzt wird. 



     Das Schmieröl   tritt durch das Zuführungsrohr   9   ein, nimmt seinen Weg durch die hohle   Welle f und   die hohle Treibstange e, wobei es die Schmierung der Lagerstellen besorgt. Der Kanal c stellt die Verbindung des   Kühlraumes b   des Kolbens a mit dem hohlen Kolbenzapfen d her. Es herrscht auf diese Weise in dem Kühlraums des Kolbens der gleiche Druck, wie in der hohlen 
 EMI1.2 
   Erwärmung   oder Verharzung des Schmieröls nicht eintreten   kann. Der Abnnss   des   Schmieröls   aus dem gekühlten Kolben a erfolgt durch das Abflussrohr h. 



   Um nicht gleichzeitig mit. dem Abstellen der Maschine auch Aufhören des Umlaufes des   Schmiermittels   eintreten zu lassen, ist ein   Windkessel   (i) in die Leitung (g) geschaltet worden. 



  Dadurch wird erreicht, dass der in dem Windkessel sich bildende Luftdruck ein weiteres Durchpressen des Kühlmittels bedingt, auch wenn die Maschine abgestellt wird. Das hat zur Folge, dass weitere Abführung der im Kolben aufgespeicherten Wärme auch nach dem Abstellen stattfindet und mit   Sicherheit Überhitzung   und Harzbildung des Schmiermittels vermieden wird. Wiirde der Windkessel nicht vorhanden sein, so wäre die Folge, dass sofort beim Abstellen der Olumlallf

  Piston cooling for engine.



   The invention relates to a piston cooling system for an engine by means of a lubricant which is passed through the hollow crankshaft, drive rod and crank pin into the cooling chamber of the piston.



   The invention consists in that an air chamber is switched into the supply line to the
 EMI1.1
 Lubricating oil is also used to cool the upper part of the piston.



     The lubricating oil enters through the feed pipe 9, takes its way through the hollow shaft f and the hollow drive rod e, whereby it worries the lubrication of the bearing points. The channel c connects the cooling chamber b of the piston a with the hollow piston pin d. In this way there is the same pressure in the cooling chamber of the piston as in the hollow one
 EMI1.2
   Heating or resinification of the lubricating oil cannot occur. The lubricating oil is drained from the cooled piston a through the drain pipe h.



   So as not to be at the same time. To allow the lubricant to stop circulating when the machine is switched off, an air chamber (i) has been connected to line (g).



  This means that the air pressure that forms in the air chamber causes the coolant to be forced through further, even when the machine is switched off. As a result, the heat stored in the piston continues to be dissipated even after it has been switched off, and overheating and resin formation of the lubricant is definitely avoided. If the air chamber were not available, the consequence would be that immediately when the Olumlallf is switched off
