  "textContent": "An injector comprises a tubular nozzle body having a nozzle side, receiving a needle valve member, and an actuator side, receiving a tubular magnetic armature and receiving an armature side of a tubular pole piece above the magnetic armature, wherein the nozzle body and the pole piece are welded together through a seam weld line between an inner tubular surface of the actuator side of the tubular nozzle body and an outer tubular surface of the armature side of the pole piece. The actuator side of the tubular nozzle body comprises a constricted area while the outer surface of the armature side of the pole piece comprises a recessed area, the constricted area and the recessed area contacting each other at a level of the seam weld line and providing a friction area transmitting hydraulic load away from the seam weld line.",
