The electronic expansion valve of one embodiment of the present invention comprises: a valve body having a communication space formed therein and having an inlet and a plurality of outlets, connected to the communication space; a ball member installed in the communication space and having a connection channel through which the inlet selectively communicates with one of the plurality of outlets; and a seat part disposed between the valve body and the ball member to relay the outlet and the connection channel, wherein the seat part has a through-hole in communication with the outlet, and a notched seat having an expansion line extending from one side of the through-hole to gradually reduce an open area, to control the state of a refrigerant discharged through the outlet according to the rotation of the ball member. Therefore, the present invention provides a simpler structure that expands or bypasses the refrigerant by using the plurality of outlets. Un détenteur électronique selon un mode de réalisation de la présente invention comprend : un corps de soupape ayant un espace de communication formé à l'intérieur de celui-ci et ayant une entrée et une pluralité de sorties, reliées à l'espace de communication ; un élément bille installé dans l'espace de communication et ayant un canal de liaison à travers lequel l'entrée communique sélectivement avec l'une de la pluralité de sorties ; et une partie siège disposée entre le corps de soupape et l'élément bille pour relayer la sortie et le canal de liaison. La partie siège comprend un trou traversant en communication avec la sortie, et un siège à encoche comportant une ligne d'expansion s'étendant à partir d'un côté du trou traversant pour réduire progressivement une zone ouverte, afin de contrôler l'état d'un fluide frigorigène évacué à travers la sortie en fonction de la rotation de l'élément bille. Par conséquent, la présente invention concerne une structure plus simple qui dilate ou contourne le fluide frigorigène à l'aide de la pluralité de sorties. 본 발명의 일 실시 예의 전자식 팽창밸브는 내측으로 연통공간이 형성되고, 상기 연통공간에 연결되어 유입구와 복수의 유출구가 형성된 밸브바디; 상기 연통공간에 설치되고, 상기 유입구와 복수의 상기 유출구 중 어느 하나를 선택적으로 연통시키는 연결유로가 형성된 볼부재; 및 상기 밸브바디와 상기 볼부재 사이에 배치되어 상기 유출구와 상기 연결유로를 중계하는 시트부;를 포함하고, 상기 시트부는 상기 유출구와 연통된 스루홀과, 상기 스루홀의 일 측에서 개방면적이 점진적으로 감소되도록 연장된 팽창라인이 형성된 노치시트가 형성되어 상기 볼부재의 회전에 따라 상기 유출구로 배출되는 냉매의 상태를 제어하는 것을 특징으로 하여, 복수의 유출구로 냉매를 팽창 또는 바이패스 시키는 보다 간소한 구조를 제공한다.
