Abstract
A cooling duct piston () for combustion engines. The cooling duct piston has a piston basic body () that is connected to a lining part (), which is facing an assigned combustion chamber. Here, the lining part () completely forms the piston surface () of the cooling duct piston () that faces the combustion chamber. An encircling depression () is provided in the surface of the piston basic body () facing the combustion chamber. The lining part () provides a permanent connection at least with the surface of the piston basic body () facing the combustion chamber, and thus bridges the encircling depression (), such that the encircling depression (), with the lining part () that bridges it, forms a cooling duct ().
