Abstract
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.
