Abstract
A device comprises an armature movable in a first direction and a second direction for causing a needle to contact and separate from a seat assembly. Stop means provide a motion stop in at least the first direction. Damping means are applied to the needle for reducing bounce of the needle when the needle contacts the stop means, by altering spring rates and vibration modes of the needle.
