More Information
Summary:The present invention relates to an injector for reducing skin effect, including: a coil assembly which is provided in a housing and forms a magnetic field when a current is applied; a magnetic core provided inside the coil assembly; an armature magnetized by the magnetic core; a needle bar which penetrates the armature and moves as the armature is magnetize; and a magnetic flux induction core provided in a hollow unit of the magnetic core. The magnetic flux induction core has greater permeability than the magnetic core. The present invention can reduce skin effect that a magnetic flux is induced to the outer wall of the magnetic core. 본 발명은 하우징 내에 구비되며, 전류가 인가되면 자기장을 형성시키는 코일 어셈블리, 상기 코일 어셈블리 내측에 구비되는 마그네틱 코어, 상기 마그네틱 코어에 의해 자화되는 아마추어 및 상기 아마추어를 관통하며, 상기 아마추어가 자화됨에 따라 거동하는 니들 바 및 상기 마그네틱 코어의 중공부에 구비되는 자속 유도 코어를 포함하고, 상기 자속 유도 코어는 상기 마그네틱 코어보다 큰 투자율(permeability)을 가지는 것을 특징으로 하는 스킨 이펙트 저감을 위한 인젝터로서, 본 발명에 의하면, 마그네틱 코어 외벽으로 자속이 유도되는 스킨 이펙트를 저감시킬 수가 있다.
