ABSTRACT:
An electromagnetically actuatable fuel-injection valve for injection systems of internal combustion engines has a valve housing, a soft-iron core which is located within the valve housing and bears a fixed solenoid winding, and a valve closure plate which forms an armature and coaxially faces said core forming an air gap with it. This plate can be urged by a compression spring against an annular seat 10 which surrounds an outlet, and whose radially circumferential edge is guided in axial movement along a guide which correspondingly surrounds said edge. The valve closure plate has a coaxially protruding plug which extends through or into the outlet.
