Abstract
A fluid metering valve includes a housing, an electromagnetic actuator that includes an armature that is separated from an inner wall of the housing by an annular gap, a throttle element connected to the armature or the housing and arranged in the annular gap to dampen a movement of the armature that is opposite to an opening direction, a valve seat surface, a valve closing body that cooperates with the valve seat surface to form a sealing seat, and a valve needle that (a) is actuatable by the actuator, (b) is arranged for actuating the valve closing body (c) extends through a borehole in the armature so that the armature is movably guidable on the valve needle, and (d) includes a stop arranged such that, during an actuation, the armature strikes against the stop in the opening direction to thereby open the sealing seat.
