Abstract:
A piston has a piston head, a piston pin support projecting from the piston head, and a mantle wall connected to the piston head. The mantle wall is formed with two tubular pieces that are disposed concentrically relative to one another and which are connected at a periphery of the piston head. A hollow space is formed between the tubular pieces.
