Claim 8:
9. The thermodynamic cycle process according to claim 1, wherein:
a first pressure is applied on a first surface of a first side of said free piston toward a first direction of said free piston sliding, and
a second pressure is applied on a second surface of a second side of said free piston opposite to said first side toward a second direction of said free piston sliding,
said first surface being smaller than said second surface,
a first product of said first pressure by said first surface being higher than a second product of said second pressure by said second surface, during a major part of said free piston sliding stroke in said first direction, and
the first product of said first pressure by said first surface being lower than second product of said second pressure by said second surface, during a major part of said free piston sliding stroke in said second direction.
