PURPOSE:To reduce pressure variation by constructing two sets of Stirling engines while employing two expansion cylinders and compression cylinders arranged in perpendicular direction each other and communicating their sealing chambers. CONSTITUTION:Two expansion piston rods 15, 17 are arranged in same direction on single crank shaft 11 while two compression piston rods 19, 20 are arranged while facing each other in perpendicular direction against said rods 15, 17. A set of expansion cylinder 37 and compression cylinder 24 are communicated through a regenerator 33 and a radiator 34 to achieve Stirling cycle. Guide pistons 16, 21 are provided at the lower section of respective piston 25, 36 while a gas seal diaphragm 27 is also provided. Then the diaphragm chambers of two compression cylinders are communicated through a tube 42. Since there is 180 deg. phase shift between both chambers, the inner volumes will become approximately same.
