摘要： In a pressure controlling valve 3 for causing deformation of a resilient member 32 by a pressure difference between a CO2 gas pressure in a sealed space (heat sensitive portion) corresponding to a refrigerant temperature and a high pressure of the CO2 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.

摘要： A supercritical cycle comprises an evaporator, a compressor, a gas cooler and a main valve portion of an expansion valve arranged in that order. An internal heat exchanger is arranged for exchanging heat between the high-pressure side refrigerant flowing toward the main valve portion of the expansion valve from the gas cooler and the low-pressure side refrigerant flowing toward the compressor from the evaporator. The expansion valve is formed integrally with a temperature sensing portion for controlling the main valve portion, and includes a bypass for supplying the refrigerant to the temperature sensing portion from the upstream side of the internal heat exchanger in which the high-pressure side refrigerant flows and an orifice for supplying the refrigerant from the temperature sensing portion to the refrigerant circuit downstream of the main valve portion.
