PROBLEM TO BE SOLVED: To enable to freely set phase difference of movement of two pistons and to take a long stroke in a Stirling cycle apparatus. SOLUTION: Two main spur gears of an equal pitch circle diameter are arranged at a position for arranging the same in a front surface, a vertical crank pin is attached to each spur gear, and the crank pins are connected to two crossheads via connecting rods. A third shaft is arranged at a position in parallel with the two main spur gears, spur gears of the equal pitch circle diameter are fixed on both sides of the third shaft by friction joint. Two piston movement mechanism of the arbitrary Stirling cycle apparatus is constructed by a gear mechanism properly meshing with the two opposing main spur gears. COPYRIGHT: (C)2006,JPO&NCIPI
