A driving or driven device designed to operate in a manner wherein the working fluid undergoes a closed cycle closely approximating a specified thermodynamic cycle. The driving or driven device comprises a number of containment spaces also referred to as cylinders (9,10,11,12) with corresponding pistons, operated in a defined sequence in relation to one another. A working fluid is transferred sequentially between cylinders directly or via heat exchangers (13,14), valves (16), or other devices as required, which together with a suitable choice of number of cylinders, selection of their proportions and the phase of operation of their pistons in relation to one another, define the thermodynamic cycle which the working fluid undergoes according to the needs of the designer. The high degree of thermodynamic reversibility achievable permits the construction to be adapted as a driven device acting as a heat pump. As a driving device heat may be supplied by external combustion. |
