Abstract:
1. An electromagnetic valve mechanism, comprising: a magnetizable block having a top and a bottom, and internally defining a chamber; and the magnetizable block being formed from a left and a right magnetizable block part, which are spaced from but face toward each other; an upper permanent magnet being superposed on the top of the magnetizable block, and having an upper flat surface; and the upper permanent magnet being formed from a left and a right upper permanent magnet, which are spaced from but face toward each other; a magnetizable upper cover being superposed on the upper flat surface of the upper permanent magnet; a lower permanent magnet being attached to the bottom of the magnetizable block, and having a lower flat surface; and the lower permanent magnet being formed from a left and a right lower permanent magnet, which are spaced from but face toward each other; a magnetizable lower cover being attached to the lower flat surface of the lower permanent magnet; an armature being movably received in the chamber in the magnetizable block, and including an armature stem, which downward extends through the magnetizable lower cover to an outer side thereof to connect with a valve stem; a magnetizable ring with two opposite protrudent rods being located around the armature; an electromagnetic coil unit including a left electromagnetic coil and a right electromagnetic coil that are separately wound around the two opposite protrudent rods of the magnetizable ring; a valve being connected to a lower end of the valve stem; and a spring unit being disposed around the armature stem and the valve stem with an upper and a lower end of the spring unit pressing against the magnetizable lower cover and a machine body, respectively.
