PROBLEM TO BE SOLVED: To provide a stirling type refrigeration machine capable of decreasing invalid volume and restricting reduced refrigeration performance.SOLUTION: A stirling type refrigeration machine in accordance with the preferred embodiment is constituted in such a way that a pressure bulkhead at a compression part is composed of a bellows 18A and there is provided a compression mechanism A receiving pressure variation under expansion or shrinkage of the bellows 18A. A spacer 20A is arranged in the bellows 18A through a gap g1 for flowing refrigerant. The gaseous refrigerant in the compression chamber 4 receiving pressure variation due to expansion or shrinkage of the bellows 18A passes through the gap g1 between the bellows 18A and the spacer 20A and flows to a regenerator 9.SELECTED DRAWING: Figure 1 |
