Abstract
A valve for metering a fluid, which is used in particular as a fuel injector for internal combustion engines, includes an electromagnetic actuator and a valve needle, which is actuatable by the actuator, and is used for actuating a valve closing body, which interacts with a valve seat surface to form a seal seat. An armature of the actuator has a through hole, through which the valve needle extends. The armature is guided on the valve needle movably and with clearance. Furthermore, a stop surface which is fixed in place with respect to the valve needle is provided, on which the armature strikes with its end face in conjunction with an actuation. During an axial alignment of the armature with respect to the valve needle, an angle offset is predefined between the stop surface and the end face of the armature.
