   Die Platte 2 ist leicht auswechselbar und samt dem Kühlraum des Kolbens leicht zu reinigen. Ausserdem ist es möglich, die Platte auch an den vom Kühlwasser bespülten Flächen zu bearbeiten und dadurch die Kühlwirkung zu verbessern. Durch die Gewährleistung freier radialer Ausdehnung des heissen Kolbenbodens wird die Entstehung von Wärmespannungen vermieden. Trotzdem ist eine gute   Abstützung   der Platte gegen achsiale Beanspruchungen vorhanden. 



   Durch die Trennung in zwei Kühlräume wird erreicht, dass nicht der ganze Kolbenkühlraum von den die Platte stützenden Rippen durchsetzt wird, so dass dadurch nur eine teilweise Beeinflussung der Kühlwirkung des   Kolbens eintreten ;iann.   Ebenso werden dadurch diese Rippen kurz ausfallen, so dass sie schwächer gehalten werden kann. Sie können zudem an besonders geeignete Orte hin verlegt werden, was   beim Hinabreichen auf   den unteren Boden des Kühlraumes wegen der Anbringung der Zu-und Ableitungen des Kühlwassers, der   Kernlöcher   usw. nicht in gleichem Masse der Fall ist.

   The plate 2 is easy to replace and, together with the cooling chamber of the piston, easy to clean. It is also possible to work on the plate on the surfaces flushed by the cooling water and thereby improve the cooling effect. By guaranteeing free radial expansion of the hot piston crown, the creation of thermal stresses is avoided. Nevertheless, the plate is well supported against axial loads.



   The separation into two cooling chambers ensures that the entire piston cooling chamber is not penetrated by the ribs supporting the plate, so that the cooling effect of the piston can only be partially influenced. This will also make these ribs short so that they can be kept weaker. They can also be relocated to particularly suitable locations, which is not equally the case when reaching down to the lower floor of the cooling space because of the attachment of the inlet and outlet lines for the cooling water, the core holes, etc.

   The interior of the cylinder is closed off by a plate which covers the entire piston, characterized in that the plate is supported by a plurality of essentially symmetrically arranged ribs extending through the cooling spaces.
