The present invention relates to an electronic expansion valve comprising: a valve body in which an inlet and an outlet communicate with each other through a valve orifice; a shell member formed in a container shape having an opening at one end, installed with the opening being sealed by the valve body, and having a coupling groove at the other end; a nut member press-fitted into the coupling groove and having a feeding screw hole with a spiral; a needle assembly installed so as to be at least partially included in the shell member while being coupled into the feeding screw hole of the nut member to be movable through rotation, and configured such that a needle for opening and closing the valve orifice protrudes from the opening; a magnet installed around the needle; and a stator disposed around the shell member.

    본 발명은 전자 팽창 밸브에 관한 것으로서, 유입구와 유출구가 밸브 오리피스를 통해 연통되게 형성되는 밸브 몸체; 일단에 개구가 형성된 용기 형상으로 이루어지며 상기 개구가 밸브 몸체에 밀봉되게 설치되며 타단에는 결합홈이 형성되는 쉘 부재; 상기 결합홈에 압입되며 나선이 형성된 이송 나사공이 형성되는 너트 부재; 상기 너트 부재의 이송 나사공에 회전을 통해 이송 가능하게 나사 결합된 상태로 상기 쉘 부재 내에 적어도 일부가 포함되도록 설치되고, 상기 밸브 오리피스를 개폐하기 위한 니들이 상기 개구로부터 돌출되도록 구성되는 니들 조립체; 상기 니들의 둘레에 설치되는 마그넷; 및, 상기 쉘 부재의 둘레에 배치되는 스테이터를 포함하여 구성되는 것을 특징으로 한다.
