PROBLEM TO BE SOLVED: To provide an expansion valve of an air conditioning system in which an external variable type compressor for a vehicle capable of reducing a manufacturing cost is applied.SOLUTION: An expansion valve of an air conditioning system for a vehicle includes a body member in which a first flow path and a second flow path separated from each other are formed, a moving member which is connected inside the body member so as to move in a set direction, with one end being exposed to the first flow path for transmission of a pressure of the first flow path, and the other end opening/closing the second flow path, and an elastic member for elastically supporting the moving member in the first flow direction. By movement of the moving member caused by a difference between a pressure inside the first flow path and an elastic force of the elastic member, the second flow path is opened or closed.SELECTED DRAWING: Figure 2
【課題】製造費用を節減できる車両用外部可変式圧縮器を適用したエアコンシステムの膨張バルブを提供する。【解決手段】車両用エアコンシステムの膨張バルブは、互いに離隔した第1流路及び第2流路が形成された本体部材と、前記本体部材の内部に設定された方向に移動するように結合されて、一端は前記第1流路に露出されて第1流路の圧力が伝達され、他端は前記第2流路を開閉するように具備された移動部材と、前記移動部材を前記第1流路方向に弾性支持するように具備された弾性部材を、を含み、前記第1流路内部の圧力と前記弾性部材の弾性力との差により前記移動部材が移動することによって第2流路が開放または閉鎖されることができる。【選択図】図2
