Claim 6:
7. The thermodynamic cycle process according to claim 6, wherein:
an axial length of said communicating channel is located between two radial lengths of said communicating channel,
an end of one radial length of said communicating channel:
opens into said expansion space at end of free piston sliding stroke in said first direction, and

an end of the other radial length of said communicating channel:
opens into said admission space at end of free piston sliding stroke when said free piston slides in said first direction,
leads against free piston external wall during the major part of free piston sliding stroke from beginning when said free piston slides in said first direction,
opens into said admission space at beginning of free piston sliding stroke when said free piston slides in said second direction, and
leads against free piston external wall during the major part of free piston sliding stroke until end when said free piston slides in said second direction.
