Abstract
A piston for an internal combustion engine, comprising a piston head ( ) and at least one cooling chamber ( ) that can be supplied with oil and is arranged underneath the head ( ) 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 ( ) 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 ( ) against projections that are located at a height corresponding to approximately half way up the hub supports in the direction of the piston head ( ).
