摘要

The compression to expansion timing ratio of gas in PTC has effect on the cooling temperatures. The timing ratio can be changed through changing the dimensions of rotary valve's heads. In this paper we will study the effects under different dimensions, and get different cooling temperatures. The lowest temperature has reached 35K by using the single-stage G-M type PTC. Finding the optimum dimensions of rotary valve's heads is helpful to get lower cooling temperatures of PTC and to improve the performance of the rotary valve, although these results are not universal.
