Control apparatus of electromagnetic drive valve and control method of the same |
摘要 |
A rush adjuster which adjusts a relative position between a valve body and an armature in an axial direction so that a state of zero-rush is formed is arranged between an armature shaft and a valve shaft. At a time of starting an electromagnetic drive valve, a first starting current is applied to either one of an upper coil and a lower coil for generating electromagnetic forces for attracting the armature closer, whichever a distance with respect to the armature is shorter.
