Regarding the stability of cryocooler, a new idea of improving the close force of valve was discussed. It is considered that flux change is resulted from the fluxion area change of valve, and the fluxion area change of valve is resulted from the force change of regulator. If a close force of valve is preset, the close force change of valve is equivalent to the fluxion area change of valve. Then the stability of cryocooler can be improved....
