ABSTRACT:
An electromagnetically actuatable fuel injection valve which has an internal scavenging system for cleaning dirt particles from a magnetic field air gap. A portion of the fuel flowing in via an inflow line and an inflow opening reaches the vicinity of an air gap defined on one side by an armature and on the other by magnetic poles and flows through this gap, and then flows via an outflow opening to enter an outflow line that communicates with a fuel return. As a result of the described scavenging of the air gap, dirt particles are prevented from becoming firmly attached there and causing impairment of the performance of the fuel injection valve.
