Disclosed is an expansion valve to minimize energy loss by spraying refrigerant at an angle which is the closest with respect to a refrigerant progress direction. The expansion valve comprises: a valve body in which a first flow path and a second flow path for the inflow and outflow of refrigerant are formed to be spaced from each other in a longitudinal direction; a rod of which an end portion passes through the first flow path to extend in the second flow path in a longitudinal direction of the valve body; a head provided at one side of a longitudinal direction of the valve body, and moving the rod to reciprocate in a longitudinal direction in accordance with a temperature of the refrigerant; an elastic member provided in the second flow path for an elastic force to be applied to the rod; and an opening and closing unit provided between the end portion of the rod and the elastic member to open and close an orifice hole of the second flow path. Moreover, an inclination portion is formed toward the refrigerant progress direction in an outlet side (L) of the orifice hole to which the refrigerant is sprayed.

    냉매 진행 방향에 대해 최대한 가까운 각도로 냉매를 분무시켜 에너지 손실을 최소화하는 팽창밸브가 개시된다. 팽창밸브는 냉매의 유,출입을 위한 제1 유로 및 제2 유로가 길이 방향으로 이격 형성된 밸브 본체와, 상기 밸브 본체의 길이 방향으로 단부가 제1 유로를 통과하여 제2 유로까지 연장되는 로드와, 상기 밸브 본체의 길이 방향 일측에 구비되며 냉매의 온도에 따라 상기 로드를 길이 방향으로 왕복 이동시키는 헤드와, 상기 로드 측으로 탄성력이 작용하도록 제2 유로에 구비되는 탄성부재와, 상기 로드의 단부와 탄성부재의 사이에 구비되어 제2 유로의 오리피스홀을 개폐하는 개폐부를 포함하며, 냉매가 분무되는 오리피스홀의 출구면(L)에 냉매 진행 방향을 향해 경사부를 형성한다.
