본 발명은 차량용 공조시스템의 팽창밸브에 관한 것으로, 보다 상세하게는 응축기로부터 전달된 냉매가 유입되는 유입유로와 팽창된 냉매를 증발기로 내보내는 유출유로 사이에 형성된 교축유로를 개폐하는 볼밸브를 포함하는 차량용 공조시스템의 팽창밸브에 있어서, 상기 볼밸브의 상부에 배치되며 상부 다이어프램 및 하부 다이어프램에 의해 밀봉되는 감온부; 상단이 상기 하부 다이어프램에 연결되고 하단이 볼밸브에 접촉되며 하부 다이어프램의 상하 변형에 따라 상하로 이동 가능한 밸브 로드; 상기 감온부의 상부에 배치되며 증발기로부터 전달된 냉매를 압축기로 배출하는 제 1 냉매유로; 및 상기 감온부의 하부에 배치되며 증발기로부터 전달된 냉매를 압축기로 배출하는 제 2 냉매유로; 를 포함하며, 상기 증발기로부터 배출된 냉매는 상하로 분기(分岐)되어 제 1 냉매유로와 제 2 냉매유로로 전달되는 것을 특징으로 하는 차량용 공조시스템용 팽창밸브에 관한 것이다.

    The present invention relates to a thermal expansion valve of an air conditioning system for a vehicle. More specifically, the thermal expansion valve of an air conditioning system for a vehicle according to the present invention, relates to a ball valve which opens and closes a throttling passage formed between an inlet passage into which a refrigerant conveyed from a condenser flows and an outlet passage which discharges an expanded refrigerant to an evaporator. The thermal expansion valve of an air conditioning system for a vehicle according to the present invention comprises: a thermal part disposed in the upper part of the ball valve and enclosed by an upper diaphragm and a lower diaphragm; a valve rod having an upper end connected to the lower diaphragm and a lower end coming in contact with the ball valve and being movable up and down by the vertical deformation of the lower diaphragm; a first refrigerant passage disposed in the upper part of the thermal part and discharging the refrigerant conveyed from the evaporator to a compressor; and a second refrigerant passage disposed in the lower part of the thermal part and discharging the refrigerant conveyed from the evaporator to the compressor, wherein the refrigerant discharged from the evaporator is branched up and down and transferred to the first refrigerant passage and the second refrigerant passage.
