Abstract

Ausgehend von einem Kolben (1), insbesondere für eine Brennkraftmaschine, mit einer Kolbenbolzenbohrung (4) zur Aufnahme eines Kolbenbolzens (5) sowie mit einem innerhalb eines Ringfeldes (2) angeordneten Kühlkanal (6), wird die Aufgabe, eine bessere Ölzufuhr zu der Bolzenbohrung mit dem Ziel besserer Schmierung und Kühlung zu erreichen, dadurch gelöst, daß der Kühlkanal (6) über zumindest eine Verbindung (7) mit der Kolbenbolzenbohrung (4) verbunden ist.

Figure 00000001
Starting from a piston (1), in particular for an internal combustion engine, with a piston pin bore (4) for receiving a piston pin (5) and with a cooling channel (6) arranged within an annular field (2), the task is to provide a better oil supply to the Pin bore with the aim of achieving better lubrication and cooling, solved by the fact that the cooling channel (6) is connected to the piston pin bore (4) via at least one connection (7).
