Abstract
A valve for metering a fluid, including an electromagnetic actuator and a valve needle which is actuatable by an armature of the actuator and used to actuate a valve closing body which cooperates with a valve seat surface to form a seal seat. The armature is movably guided at the valve needle in the process. A stop element connected to the valve needle limits a relative movement between the armature and the valve needle in connection with an actuation of the valve needle. At least one elastically deformable spacer element is provided between the armature and the stop element, which, during the limitation of the relative movement between the armature and the valve needle at the stop element, encloses an attenuation space provided between a front face of the armature and a stop element surface of the stop element facing the front face of the armature.
