<p>A Fluid injector comprises a housing (8) with a cavity and a coil (34) being arranged in the cavity. A valve needle (12) being arranged axially moveable along a predetermined axis (L) of the fluid injector. An armature (14) being arranged axially moveable along the predetermined axis (L) and being mechanically coupled to the valve needle (12). A reluctance element (42) is designed to have a permeability which is much smaller than the permeability of the housing (8) and is arranged such that a magnetic circuit comprising the housing (8) and the armature (14) also comprises the reluctance element (42).</p> |
