본 발명은 팽창밸브에 관한 것으로써, 더욱 상세하게는 증발기의 분리된 2개의 증발부로 각각 냉매를 팽창하여 분배 공급하도록 2개의 오리피스(제1,2오리피스)를 갖는 팽창밸브에서, 상기 제1,2오리피스의 개도를 조절하는 제1,2밸브를 분리 설치하고, 상기 제1,2밸브의 사이에는 상기 제1밸브의 변위량에 따라 제2밸브를 변위시키는 연결수단을 설치함으로써, 저부하(낮은 냉방부하) 조건에서는 제2오리피스를 폐쇄할 수 있게 되어 냉매유량 최소화를 통해 소요동력 최소화 및 연비를 향상할 수 있고, 고부하(높은 냉방부하) 조건에서는 제1,2오리피스로 냉매유량을 분배하므로, 각 부하 조건에 따라 최적의 냉매유량 분배가 가능하여 연비 개선 효과를 극대화 함은 물론 최적의 냉방성능 및 냉방효율을 얻을 수 있는 팽창밸브에 관한 것이다.

    The present invention relates to an expansion valve and, more specifically, to an expansion valve with two orifices (a first and a second orifice) to respectively distribute and supply a refrigerant to two evaporation part, which are divided from an evaporator, after expanding the refrigerant, wherein the expansion valve comprises: a first and a second valve installed separately, and controlling the opening degrees of the first and the second orifices; and a connection unit installed between the first and the second valves, and displacing the second valve depending on the displacement of the first valve. Therefore, under a low load (a low cooling load) condition, the second orifice can be closed to minimize power consumption and improve fuel efficiency through the minimization of the flow rate of the refrigerant, and under a high load (a high cooling load) condition, the flow rate of the refrigerant is distributed to the first and the second orifices, so the flow rate of the refrigerant can be optimally distributed according to the respective load conditions, thereby maximizing the improvement of the fuel efficiency and obtaining an optimal cooling performance and cooling efficiency.
