ABSTRACT:
A flow control valve utilizing at least one permanent magnet and at least one magnetic coil, wherein one or more permanent magnets or magnetic coils are used to move a movable member in towards and/or away from an inflow port so as to control the flow through the port. When multiple permanent magnets are used, at least one yoke, which protrudes beyond the edges of the magnets, is place between each pair of magnets. A fixed shaft that passes through a hollow portion of the movable member is used to control the movement of the movable member, and an air vent is present near the end of the movable member that is closest to the inflow port such that the hollow space of the movable member does not form a vacuum.
