Magnetic valve

Image Number 2 for United States Patent #4512549.

A magnetic valve in which two cylindrical soft-iron cores are provided which are disposed parallel to one another. The soft-iron cores are each surrounded by a coil. An armature of magnetically conductive material which carries a valve body is caused to move inside the soft-iron cores. Between the two coils, an axially magnetized permanent magnet is disposed in circular-annular fashion. The soft-iron cores have a magnetic short-circuit connecting them with one another.
