ABSTRACT:
A pressure control valve includes pressure modulating section and a magnetic section. The magnetic section has a cylindrical case, a coil assembly, a cylindrical core, a rod and a plunger. Outer limbs of a disc type supporting members which are made of a leaf spring member are fixed to both ends of the cylindrical core, and both ends of the rod are suspended at the center of the disc type supporting members, so that the rod is supported by the disc type supporting members. Due to the above when operation, the move of the rod is performed smoothly by the supporting structure of the disc type supporting member, and the supporting member moves according to the move of the rod, so that such move of the rod brings about no volume change in the magnetic section.
