摘要

The piston (1) comprises a shaft (2) made of aluminum, particularly of high-strength aluminum alloy, which comprises a fastening unit for a tool. The shaft comprises a hollow space, which is opened on one side of the piston. The hollow space is formed as a channel (6) extending through the shaft, particularly as a borehole. The channel is partially closed by a stopper, particularly by a stopper, which closes 30 to 95 percentage of the length of the channel.
