본 발명은 팽창밸브 및 이를 구비한 차량용 공조장치에 관한 것으로써, 더욱 상세하게는 하나의 팽창밸브를 이용하여 응축기측으로부터 공급된 냉매를 분기하여 각각 팽창시킨 후 증발기측으로 배출할 때, 단일 샤프트에 의해 위치가 가변되는 제1,2밸브를 통해 제1,2오리피스의 개도를 서로 다르게 조절하도록 함으로써, 제1,2오리피스를 통과하면서 팽창되는 냉매의 유량을 서로 다르게 할 수 있게 되어 증발기의 각 증발부측으로 서로 다른 냉매 유량을 동시에 공급할 수 있고, 이로인해 에어컨의 냉방효율을 향상할 수 있으며 하나의 팽창밸브를 사용하므로 부품수 및 비용을 절감할 수 있는 팽창밸브 및 이를 구비한 차량용 공조장치에 관한 것이다.

    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.
