Abstract
A compact electromagnetic valve device for fuel injection apparatus for engines is provided with which occurrence of cavitation erosion due to rapid change in pressure in a small gap is prevented without increasing in size. Through holes are drilled in a platy armature connected to a poppet valve for opening and closing a fuel passage connecting a fuel feed/spill passage to a plunger room of a fuel injection apparatus, and a thin plate valve or check valve is provided to the armature to allow the holes to be opened or closed in accordance with upward or down ward movement of the armature connected with the popped valve.
