ABSTRACT:
The reciprocating motion of the power piston of a Stirling cycle engine is converted to rotation of an output shaft by means of a gimbal-mounted wobble plate. The output shaft has a cylindrical bearing surface whose axis is at an acute angle to that of the shaft and which surface rotates within the nonrotating wobble plate. The wobble plate oscillates about its mounting axis within the gimbal, and the gimbal in turn oscillates about a third axis which is mutually perpendicular to and intersecting with the wobble plate mounting axis and the rotational axis of the output shaft. The power piston rod is connected to the gimbal to cause it to oscillate, which in turn induces rotation of the output shaft. The reciprocation of the displacer piston is phased to that of the power piston by means of a reciprocating slide which is connected to the displacer piston rod and driven by a ball-like cam and socket interconnection with the wobble plate. The displacer piston has two segments which are axially separated by an insulator to provide maximum temperature differential between its hot and cold ends.
