The present invention relates to an integrated fluid control valve with an expansion valve function. The purpose of the present invention is to perform a directional control valve function and an expansion valve function in one body at the same time, thereby reducing the number of parts and reducing manufacturing costs. To this end, according to the present invention, the integrated fluid control valve with an expansion valve function for controlling a refrigerant of an air conditioning device comprises: a valve body having a refrigerant inlet and a refrigerant outlet; and a valve body which includes a flow control channel portion controlling the flow of a refrigerant from the refrigerant inlet to the refrigerant outlet, and a pressure control channel unit controlling the pressure of the refrigerant from the refrigerant inlet to the refrigerant outlet, and allows at least one of the flow control channel portion and the pressure control channel unit to control the refrigerant from the refrigerant inlet to the refrigerant outlet.
본 발명은 팽창밸브 기능을 갖는 통합형 유체제어밸브에 관한 것으로서, 하나의 몸체로 방향제어밸브 기능과 팽창밸브 기능을 동시에 수행할 수 있도록 구성함으로써, 부품수를 절감할 수 있고, 이를 통해 제조원가를 절감할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 공조장치의 냉매를 제어하는 팽창밸브 기능을 갖는 통합형 유체제어밸브에 있어서, 냉매도입구와 냉매배출구를 갖추고 있는 밸브바디와; 냉매도입구에서 냉매배출구로의 냉매 흐름을 제어하는 흐름제어유로부와, 냉매도입구에서 냉매배출구로의 냉매 압력을 제어하는 압력제어유로부를 구비하며, 회전위치에 따라 흐름제어유로부와 압력제어유로부 중 적어도 어느 하나가 냉매도입구에서 냉매배출구로의 냉매를 제어할 수 있게 하는 밸브체를 구비한다.
