A thermo-volumetric motor (10) includes a continuous incompressible fluid path in the form of a hydraulic oil path (12), a continuous compressible fluid path in the form of a refrigerant path (14), and a solar collector (18). The solar collector (18) is adapted to absorb heat from a heat source, in this example, sunlight. The hydraulic oil path (12) includes a pressure transfer mechanism, in this example a pair of hydraulic cylinders (20A, 20B) located in a parallel flow arrangement. The oil path (12) further comprises an actuating device, in this example a hydraulic loader (22), in fluid communication with a first heat exchanger (24). The refrigerant path (14) comprises a pump (28) operatively coupled to the hydraulic motor (22), and a heat transfer device, in this example a second heat exchanger (25). The refrigerant path (14) further comprises a cooling unit, in this example a first accumulator or condenser (32), used for cooling the refrigerant. The second heat exchanger (25) comprises a shell and tube arrangement wherein refrigerant is passed through a helical tube, and a first phase change substance, such as sodium acetate trihydrate, is contained within the shell.

[ We claim:] [1.] A thermo-volumetric motor comprising:a continuous incompressible fluid path, adapted to carry a substantially incompressible fluid, said incompressible fluid path having pressure transfer means and actuating means in fluid communication with each other;a continuous compressible fluid path being adapted to carry a substantially compressible fluid, said compressible fluid path including heat transfer means in fluid communication with the pressure transfer means, the heat transfer means including a first phase change substance having a relatively high latent heat of fusion, and cooling means in fluid communication with the heat transfer means and the pressure transfer means whereby, in use, heat from a heat source can be absorbed by the first phase change substance so that at least a portion of the first phase change fuses and thereafter when said portion of the first phase change substance solidifies and releases latent heat the compressible fluid can absorb said latent heat and expand, thus moving the pressure transfer means wherein the incompressible fluid is forced along the incompressible fluid path thus moving the actuating means which can be adapted to provide motive power, the cooling means thereafter cooling the compressible fluid after said compressible fluid is released from the pressure transfer means.
