Abstract
In a pressure controlling valve 3 for causing deformation of a resilient member 32 by a pressure difference between a CO.sub.2 gas pressure in a sealed space (heat sensitive portion) corresponding to a refrigerant temperature and a high pressure of the CO.sub.2 refrigerant in the refrigeration cycle to open and close the valve, a volume ratio Vs/(Vs-Vo) of a total volume (Vs) of the sealed space when the valve is fully closed and a total volume (Vo) of the sealed space when the valve is fully open is greater than 1.9 or 2.4. To improve this volume ratio, a cavity 31d communicating with the sealed space is formed inside a displacement transmission member 31 coupled with the resilient member, or a recess portion 35a is formed in a cover member 35a, or a member communicating with the sealed space is connected.
