Abstract

See full text

A fluid control valve comprises a ferromagnetic material portion that is formed on the spool so as to extend in the axial direction of the spool, permanent magnets that are arranged opposite each other having the middle portion therebetween in a direction orthogonal to the axial direction of the spool, form between themselves oppositely oriented magnetic fields aligned in the axial direction, and which are formed to be longer than the middle portion in the axial direction of the spool, and a coil that is arranged in a direction orthogonal to the axial direction of the spool with respect to the permanent magnets and generates a magnetic field that penetrates the opposing permanent magnets due to the conduction of electricity.
