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. In a built with an internal cold room and an outer cooling channel equipped piston for burning is between one on the inside of the engine Upper part attached ring web and one against this overlying surface of the lower part an annular flange is stuck in the cooling channel on the edge of the cooling channel channel protruding tongue is arranged.

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. To the temperature of the wall of the combustion chamber To reduce the cooling channel as much as possible while reducing the Temperature in the range of at least the first piston ring groove on one the wet corrosion of the piston and the piston ring to maintain the level preventing the tongue from forming a comparison of the combustion chamber wall of the cooling duct wise narrow annular gap, which when flowing through the cooling oil has a throttling effect.
