Beschreibung
Zusammenfassung:	An electromagnetic fluid controller can prevent the action force of magnetic attraction between both abutting faces of an armature and a stator, and eliminate the necessity of a junction of the armature and a valve needle. Upon coil energization, the armature is attracted by an electromagnetic stator force, and the armature and the stator abut through a nonmagnetic material film. The nonmagnetic material film is formed of a material containing NiP on the end face of the stator with a thickness in a range from 30 to 100 micrometers. Thus, the action force of magnetic attraction between both the abutting faces upon deenergization of the coil can be prevented without providing an air gap, and delays in the timing of the separation of the armature from the stator can be decreased.
