ーリングサイクル冷凍機。[Scope of Claim for Utility Model Registration] (1) Gas in the system compressed by the compression piston is sent to the rear chamber on one side of the displacer through a heat exchanger, passed through a regenerator in the displacer, and then is sent to the displacer. A Stirling cycle refrigerator that lowers the temperature of gas in the system by flowing into an expansion chamber on the other side of the system, the compressor cylinder having a compressor cylinder in which the compression piston reciprocates, and the compressor cylinder being partitioned by the compression piston. a piston compression chamber communicating with the rear chamber of the displacer via piping; a piston rear chamber formed on the opposite side of the piston compression chamber in the compressor cylinder and filled with extra-system gas; and the piston compression chamber. a first passage having a check valve that communicates between the chamber and the piston back chamber and allows only the inflow of outside gas from the piston back chamber to the piston compression chamber; Only when the above conditions are met, a second valve having a relief valve that allows inflow of gas within the system from the piston compression chamber to the piston back chamber.
A Stirling cycle refrigerator with a passageway. (2) The Stirling cycle refrigerator according to claim (1), wherein the first and second passages are formed in the compression piston.
