Free-piston engine, particularly double-cylinder free-piston engine, has electromechanical converter, which is operated as generator or as motor and is arranged between piston axis and axes feed through of rotary slide pistons

摘要

The free-piston engine (1) has a cylinder (2) for receiving a working medium with a piston axis (6) that runs along a central axis of the cylinder. Two rotary slide pistons are provided for compressing and releasing the working medium in a working chamber of the cylinder. An electromechanical converter (8) is provided, which is operated as a generator or as a motor and is arranged between the piston axis and the axes feed through (7) of the rotary slide pistons. The working medium comprises a noble gas such as helium.
