Claims

[Claim for Utility Model Registration] The refrigerant compressed by the compression piston is sent to the back chamber on one side of the displacer through a heat exchanger, passes through the regenerator in the displacer, and is then sent to the rear chamber on the other side of the displacer. In a Stirling cycle refrigerator that lowers the temperature of refrigerant by flowing into an expansion chamber, a plurality of compression pistons are arranged radially, and an outer ring is rotatably fitted into the eccentric body of a crankshaft that is rotationally driven by a drive machine. A radial piston drive device comprising a connecting rod of a compression piston connected to an outer ring, and a plurality of displacers arranged concentrically with the crankshaft, and a cam member fixed to one end of the crankshaft. A cam groove that is displaceable in the axial direction of the crankshaft is provided on the outer periphery, and a rod that reciprocates the displacer in the axial direction of the crankshaft is connected to the drive body inserted into this cam groove. On the other hand, there is provided a displacer drive device in which the shape of the cam member is set so that the phase of the corresponding displacer advances approximately 90 degrees; and a cooling fluid passage extending from one end side of the crankshaft to the body. A Stirling cycle refrigerator characterized by comprising:
