More Information
Summary:In an electromagnetic valve, a composite valve case has a cylindrical hollow and a composite valve body formed in spool shape is slidably housed in the cylindrical hollow. The composite valve body has not only an inherent valve function for changing fluid path area according to its movement in the cylindrical hollow but also an armature function for constituting a magnetic circuit. The composite valve case has not only a cylinder function for allowing the valve body to slidably move but also a stator function for constituting a magnetic circuit. The composite valve body and the composite valve case are made of soft magnetic material and are provided at their surfaces with thin hardened layers formed by surface or heat treatment
