PROBLEM TO BE SOLVED: To provide a drive mechanism with minimal side loads on pistons, in the pistons and the drive mechanism to convert the linear motion of a reciprocating piston of a stirling cycle machine to rotary motion.SOLUTION: A Stirling cycle machine includes a rocking drive mechanism 200 which includes a rocking beam 216 having a rocker pivot 218, cylinders 206, 208, and pistons 202, 204. The piston is capable of substantially linearly reciprocating within the respective cylinders. Also, the drive mechanism includes coupling assemblies 210, 212 having a proximal end and a distal end. The proximal end is connected to the piston and the distal end is connected to the rocking beam by end pivots 232, 236. The linear motion of the piston is converted to rotary motion of the rocking beam, to be transferred to a crankshaft 214 coupled to the rocking beam via a connecting rod 222. |
