Summary

The step piston type pulse tube refrigerator is a new power recovery type pulse tube refrigerator, requiring a novel component: the step piston linear compressor. Compared with the general linear compressor, the step piston linear compressor features a step-shaped piston and cylinder, forming compression chamber and expansion chamber with the same volume change phase. This paper proposes the development for the step piston linear compressor, describing the detail design of the step piston, linear motor, and spring. Its feasibility was verified through experiments with the step piston type pulse tube refrigerator. The results demonstrated a maximum input electrical power of 792 W and a maximum cooling power of 140 W.
