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. The plunger is made of thick magnetic material. At the center of the plunger, a cylindrical concave whose diameter is slightly larger than that of the cylindrical core is provided. The end of the cylindrical core composes an extrusion by extending from the coil assembly. A magnetic attractive section made up by the cylindrical concave of the plunger and the extrusion of the cylindrical core both of which are located vis-a-vis each other, and is located away from the pressure modulating section. Due to the above, when operation the plunger is efficiently magnetized and attracted to the extrusion of the core. And even if fluid leaks from the pressure modulating section, it is difficult for the fluid to reach the magnetic attractive section.
