Abstract

There is disclosed a Stirling cycle refrigerator in which oil rising is prevented, and an adverse influence onto oil sealing bellows by a pressure rise accompanying the temperature rise of the crank chamber is prevented. The oil sealing bellows are disposed between a space in a housing and compression and expansion cylinders, and a buffer tank provided with the pressure adjusting bellows is disposed between a space on the back surface side of the compression and expansion pistons and the space in the housing, so that the pressure rise in the housing and the pressure fluctuation of the space are absorbed.
