Abstract:
The invention relates to a tubular piston for a piston engine, comprising a tubular section, a collar shaped region and a ball pivot formed thereon, and an inner tube arranged in an outer tube. A cavity is at least partially formed between the outer tube and the inner tube. Said cavity is sealed from the area surrounding the hollow piston in a pressure-tight manner, by a material, especially a solder material, which is arranged in the cavity in a positively locking manner by means of heating.
