Zusammenfassung:	PURPOSE:To provide an automatic expansion valve for a refrigerator and air conditioner, generating no hunting in a refrigerant circuit and capable of effecting stabilized operation. CONSTITUTION:In an automatic expansion valve, equipped with an overheating degree controlling mechanism 121, controlling the overheating degree of refrigerant in an evaporator, and a discharging pressure control mechanism 122, operated as an operating unit for controlling the discharging pressure of a compressor by stopping the function of the overheating degree controlling mechanism 121 when a refrigerant pressure in the inlet port of the expansion valve is higher than a set pressure and controlling the inflow amount of refrigerant into an evaporator, the discharging pressure control mechanism 122 is provided with a pressure regulating mechanism, supplying a control pressure to the overheating degree control mechanism 121 as the primary function of the discharging pressure of the compressor and an absorbing pressure.
