Abstract:
The present disclosure relates to internal combustion engines. Various embodiments thereof may include a fuel injection valve for a combustion engine comprising: a valve body with a cavity; a valve needle movable in the cavity; an actuator assembly to actuate the valve needle. The actuator assembly includes an electro-magnetic coil, a pole piece positioned inside the cavity, and an armature element. The armature element moves within the cavity to move the valve needle in a predetermined direction. A fixing ring abutting the pole piece, fixed to the valve body by means of joining to a circumferential surface of the cavity.

Claim (Index 14):
A method of operating a fuel injection valve for a combustion engine, the method comprising:\n opening the valve; and closing the valve; wherein opening the valve comprises:\n providing a magnetic field with an electro-magnetic coil; \n gathering and directing the magnetic field to an armature element with a pole piece; and \n pushing a retainer element with the armature element such that a valve needle allows a fluid to flow through a fluid outlet portion of a valve body; and \n closing the valve comprises:\n pushing the valve needle with a spring element such that the valve needle prevents the fluid from flowing through the fluid outlet portion; \n wherein a fixing ring abuts a pole piece and secures the pole piece to a circumferential surface of a cavity of the valve body, the cavity hydraulically connecting a fluid inlet portion to the fluid outlet portion.
