Abstract
A fuel-injection valve comprises an electromagnetically actuated armature attached to the needle-like stem of a valve head. In order to promote control of fuel flow under varying conditions the valve opens by moving the valve head downstream from its valve seat and the stroke of the valve head is limited by a mechanical stop situated downstream of the valve seat.
