ABSTRACT:
A thermal motor is disclosed for converting heat energy to hydramechanical energy. A plurality of heat-responsive elements are mounted on a rotor to periodically expose the elements to heating and cooling. Thermally responsive elements generate a mechanical movement in response to the heating and cooling. The mechanical movement actuates a hydraulic cylinder which, in turn, operates a hydraulic motor. The output of the hydraulic motor is used to perform useful work and also to rotate the rotor. In one preferred form, the heat-responsive elements are in the form of bimetallic strips which mechanically deflect.
