Abstract

Bei einem gebauten mit einem inneren Kühlraum und einem äußeren Kühlkanal ausgestatteten Kolben für Brenn­ kraftmaschinen ist zwischen einem auf der Innenseite des Oberteils angebrachten Ringsteg und einer diesem gegen­ überliegenden Fläche des Unterteils ein Ringflansch einge­ klemmt, an dessen kühlkanalseitigem Rand eine in den Kühl­ kanal hineinragende Zunge angeordnet ist.
Um die Temperatur der brennraumseitigen Wand des Kühlkanals soweit wie möglich zu senken und gleichzeitig die Temperatur im Bereich wenigstens der ersten Kolbenringnut auf einem die Naßkorrosion des Kolbens und des Kolbenrin­ ges verhindernden Niveau zu halten, bildet die Zunge mit der brennraumseitigen Wand des Kühlkanals einen vergleichs­ weise engen Ringspalt, der beim Hindurchströmen des Kühl­ öls einen Drosseleffekt ausübt.
