ABSTRACT:
A heat engine comprising a cylindrical heat chamber having an end wall of insulating material and on which is mounted a cylinder. An opening in the end wall communicates between the heat chamber and the cylinder. The cylinder is surrounded by a cooling jacket and a piston reciprocates in the cylinder. The end of the cylinder remote from the end wall is open and a connecting rod has one end secured to the cylinder and the other end to a fly wheel. A second rod extends from the cylinder through the opening in the end wall and through another opening in a second end wall in the heat chamber. A disc like valve is slideably mounted on this rod and is moveable into a position opening and closing the opening. Cooperating elements of a dash pot are formed on the piston rod and valve at each end of the latter. A heat sink is provided on the lower side of the heat chamber and a throttle passage extends between the heat chamber and the cylinder. A needle valve cooperates with this passage and is under the control of a governor.
