摘要

The thermal power machine or thermally working machine (1) comprises a closed working space (2) filled with an operating liquid. A displacement piston is provided that is a free flying piston (5) without a piston rod. An acting force is driven from outside the working space in a contactless manner. The acting force is driven back and forth between two end positions in the working space or in a rotating manner in the working space.
