Abstract
An electromagnetic valve mechanism includes a magnetizable block, an upper permanent magnet superposed on a top of the magnetizable block, a magnetizable upper cover superposed on an upper flat surface of the upper permanent magnet, a lower permanent magnet attached to a bottom of the magnetizable block, a magnetizable lower cover attached to a lower flat surface of the lower permanent magnet, an armature movably received in the magnetizable block, a magnetizable ring located around the armature, an electromagnetic coil unit wound around two opposite protrudent rods of the magnetizable ring, and a spring unit disposed around an armature stem and a valve stem. By adding the permanent magnets and using the electromagnetic coil unit to thereby form a bypassed forward secondary magnetic channel, the electromagnetic valve mechanism can achieve the purposes of lowered energy consumption, reduced overall mechanism volume, providing demagnetization-protection for permanent magnets, and enhanced performance.
