Abstract: An expansion valve and an air conditioner for vehicles having the same, the expansion valve comprising a main body having an inflow channel, first and second discharge channels and first and second orifices to expand refrigerant branched from the inflow channel to the first and second discharge channels; first and second valves to control flow rates of refrigerant passing through the first and second orifices by controlling the degree of opening of the first and second orifices respectively; and a shaft slidably mounted inside the main body for varying positions of the first and second valves simultaneously so that the first and second orifices are opened or closed at the same time by the movement of the shaft.

Abstract: This document relates to an expansion valve and an air conditioner for vehicles having an expansion valve, which can branch and expand refrigerant supplied from a condenser, discharge the branched and expanded refrigerant to an evaporator, and differently control the degree of opening of first and second orifices through first and second valves varied in their positions by a single shaft, so that flow rates of refrigerant expanded while passing through the first and second orifices differ from each other, thereby differently providing refrigerant flow rates into evaporation parts of the evaporator, enhancing cool efficiency of the air conditioner, and reducing the number of components and manufacturing expenses since just one expansion valve is used.
