  • the piston 1 and the cylinder 2 form a piston-cylinder unit of the double crankshaft piston engine, which may be designed either as an internal combustion engine or as a compressor.
  • the invention is not limited to a double crankshaft piston engine with only one piston-cylinder unit.
  • the machine may also have more than one such piston-cylinder unit.
  • Such reciprocating engines are well known to those skilled in the art, so that general components, such as valves or a valve control are not shown in the figures.
