The piston (1) has a radially circulating cooling channel (6a) arranged at a distance to a piston head (2), where the piston is made of light-metal e.g. steel. Lubricating oil is injected into inlet openings (13, 14) as a cooling medium over a free jet of injection nozzles (11, 12). The channel is designed in a divided or undivided manner, and the nozzles are provided for loading the openings or a connection of the channel. The medium in the free jet enters into the openings, where the jet is directed parallel to a longitudinal axis. A lower side (20) is loaded with the medium by the jet. |
