Thermomotor
The patent describes a Stirling cycle machine of unique mechanical arrangement, comprising a rotatable engine body having a heater head at one end, with a lining of open-cell, foamed metal bonded to its inner surface; a displacer which reciprocates within the heater head; a rotor housing at the opposite end from the heater head, composed of a material which is permeable to electric and magnetic fields. The fields pass through the housing uneffected in order to induce currents into the rotor housed within the housing; cylinders disposed radially about the circumference of the engine body; pistons disposes respectively in the cylinders, the pistons connected respectively to rotatable crankshafts disposed within the engine body and positioned with respect to the axes of the reciprocating pistons. The crankshafts connected by gears or other connecting means to a rotatable central shaft so that the rotation of the central shaft is related to and dependent upon the reciprocating movements of the pistons; roller affixed to the sides of the central shaft at one end, which connect the central shaft to the displacer by means of a camming groove machined into the displacer in which the rollers ride; an electromagnetic induction rotor affixed to the opposite end of the central shaft which rotates in conjunction with the central shaft.
