Abstract:
A power machinery for a temperature-differential engine, comprisinga first valving piston; a power piston having a groove on an outer surface thereof; a second valving piston having a groove on an outer surface thereof; a spindle passing through in turn the first valving piston, the power piston and the second valving piston; and the first valving piston, the power piston and the second valving piston having reciprocating motion along the spindle; a countershaft used to keep a fixed separation between the first valving piston and the second valving piston; and a flywheel being fit on the groove through a sliding member; wherein the flywheel moves along the grooves on the power piston and the second valving piston and has a rotation motion when the first valving piston, the power piston and the second valving piston have reciprocating motion along the spindle.
