PURPOSE:To permit transmission of heat and pressure energy and excution of work onto outside by the circulation flow of fluid, by allowing fluid to flow in a circulation passage by utilizing the pressure variation caused by the expansion and contraction of expansion body in an expansion and contraction vessel, as motive-power source. CONSTITUTION:The heated fluid which is heated to a high temperature in a heat collection part into which heat is supplied from the first heat source 1 passes through a conduit 8 through a direction switching apparatus 2, and heat exchange is performed with the expansion body 10 in an expansion and contraction vessel 3. Then, said expansion body 10 expands, and the working fluid 11 to which the above-described expansion amount is transmitted is formed. Said working fluid 11 passes through a going conduit 13 and reaches a direction switching apparatus 5, and heat exchange is performed in the second heat source or a heat discharge part 7 through a working-power taking-out apparatus, and the temperature of the working-fluid is reduced. Said working fluid 12 passes through the direction switching apparatus 5 through a returning conduit 14 and introduced into a thermal expansion and contraction vessel 4, and then the expansion body 10 is compressed by the working fluid 11 having a low temperature due to heat exchange and contracted. Thus, circulation is performed in repetition by utilizing the difference generated between the vessels 3 and 4. |
