Description/Abstract 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.
