Abstract (en)
[origin: DE19926567A1] The invention relates to a cooled piston for internal combustion engines. The inventive piston is provided with an annular cooling channel on the periphery of the piston head. Said cooling channel, at its end that is open towards the piston shaft, is closed by a correspondingly shaped wall part that is radially split at least once. The aim of the invention is to improve the supply of cooling oil in the cooling channel. To this end, the wall part at the end allocated to the split is provided with a respective recess and with an upturned S-bend section that serves to deflect the cooling oil jet.
