Abstract

A valve for metering a fluid, for example, a fuel injection valve for an internal combustion engine, includes a valve-seat face, an electromagnetic actuator including an armature that includes a through-flow channel that opens with an outlet opening at an end face of the armature, a valve needle on which the armature is movably supported and that is operable using the armature, a valve-closing member that is actuatable by the valve needle and that cooperates with the valve-seat face to form a sealing seat, and a stop element that is mounted fixedly on the valve needle and that interacts with the at least one outlet opening of the at least one through-flow channel such that throttling takes place with respect to the least one through-flow channel when the armature is located with its end face at the stop element.
