Self-holding type solenoid-operated valve

Image Number 5 for United States Patent #6691740.

A self-holding type solenoid-operated valve comprises a single coil which is wound around a bobbin in one direction, a movable iron core which is disposed coaxially with a fixed iron core, a first spring which urges the movable iron core away from the fixed iron core, and an annular permanent magnet which is installed to a portion at which an end of the fixed iron core and an end of the movable iron core are opposed to one another. The annular permanent magnet partially surrounds the outer circumferential surfaces of the fixed iron core and the movable iron core.
