Abstract
A valve for use in a fuel injector includes a moveable valve member disposed in a first chamber and an armature coupled to the valve member and reciprocally disposed in a second chamber which dampens the motion of the valve member when fluid is present in the second chamber. A fluid passageway extends into the second chamber and delivers fluid to the second chamber while a further fluid passageway drains fluid from the second chamber when the fluid within the second chamber reaches a predetermined level.
