Abstract
A piston for an internal combustion engine, comprising a piston head (2) and at least one cooling chamber (4) that can be supplied with oil and is arranged underneath the head (2) of the piston, whereby the lower limit of the cooling chamber is formed by a sheet of metal that can be elastically deformed and is fixed to the piston. The objective of the invention is to enable the metal sheet (6) to be fixed in a simple manner. This is achieved by using components that are subjected to pressure, pressing the elastically deformable sheet of metal (6) against projections that are located at a height corresponding to approximately half way up the hub supports in the direction of the piston head (2).
