The piston (1) consists of a first part with base section (3) and a second part with cover (8). The base section has an outer wall (6) and a journal (7), to define the hollow ring chamber (9), which are formed integrally with the base section in a non-cutting process, e.g. by esp. cold extrusion. The first and/or the second piston part is sintered, and the parts are identical. |
