PURPOSE: An expansion valve is provided to reduce the hunting in two valves through two kinds of refrigerant returned from an evaporator. CONSTITUTION: An expansion valve comprises coolant adiabatic-expanded by first and second valves(3a, 3b) and transferred to the first and the second heat exchanger in an evaporator. The refrigerant evaporated by the first and the second heat exchangers is returned to a returning coolant inlet port(15). The returned refrigerant is passed and stirred through a throttling passage(40). A power element(17) detects the evenly stirred refrigerant and performed in stable state.
