MAGNETICALLY ACTUATED VALVE

摘要

A magnetically actuated valve is provided having a body with at least first and second orifices. The valve includes a magnetic actuating means having first and second valve members each associated with a respective magnetic field, the interaction of the magnetic fields being such that the valve members are normally urged away from each other to close the first and second orifices respectively. The magnetic actuating means also includes at least one supplementary magnetic field capable of interacting with either or both of the first and second magnetic fields to move one or both of the valve members to open a respective orifice.
