VALVE USING PERMANENT MAGNETIC POLARITY CHARACTERISTIC

摘要

PURPOSE: A valve using interaction between polarities and the polarity variation of a permanent magnet is provided to control the opening and closing of a valve by the interaction between the permanent magnet for controlling and the permanent magnet for driving. CONSTITUTION: A valve using interaction between polarities and the polarity variation of a permanent magnet comprises a driving permanent magnet(320), a controlling permanent magnet(110), a polarity changing coil(120), a fixed member(130), a guide member(200), and a moveable member(310). A polarity variable coil is wound along the control permanent magnet in order to change the polarity of for the control permanent magnet. The fixed member is located in order to fix the polarity variable coil and the control permanent magnet. The guide member is connected to the fixed member. The moveable member is guided in the guide member to reciprocate in a straight line. The driving permanent magnet is fixed to the moveable member toward the controlling permanent magnet.
