ABSTRACT:
A gas refrigerator including a driving section comprises a first piston-cylinder mechanism for compressing a gaseous refrigerating medium and a second piston-cylinder mechanism for compressing a gaseous driving medium, the first and second piston-cylinder mechanisms being driven with a phase difference of approximately 90.degree., and a refrigerating section comprising a cylinder and a floating piston disposed in the cylinder to define an expansion chamber at one end and a driving chamber at the other end. The first and second piston-cylinder mechanisms respectively communicate through conduits which may be constructed of flexible material, with the expansion and driving chambers. A gas cooling device is provided in the first piston-cylinder mechanism.
