ABSTRACT:
A thermal engine system is characterized by a cylinder having a suitable working fluid disposed therein and having a piston reciprocally movable in first and second directions within the cylinder, the piston dividing the cylinder into first and second pressurization regions. In one embodiment, a thermally responsive, expansible member is operatively connected directly at one free terminus thereof to the piston. In an alternate embodiment, the free terminus of the thermally responsive, expansible member is indirectly attached to one or more double-acting piston-cylinders through lever connections. The thermally responsive, expansible member is connected at the second end thereof to suitable means for maintaining the second end of the expansible member in a substantially stationary position. The thermally responsive, expansible member responds to the temperature of driving fluids introduced thereto to alternately thermally expand and contract to thereby cause reciprocating motion of the piston within the cylinder. Reciprocation of the piston within the cylinder alternatively pressurizes working fluid disposed within the first and the second regions of the cylinder. The pressure energy transmitted to the working fluid in the first and second regions of the cylinder is stored within a suitable energy storing arrangement to be utilized in any desired manner.
