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.

A valve for a fuel injector, comprising: a moveable valve member disposed in a first chamber and movable to an open position to allow a first fluid to pass; means coupled to the valve member and disposed in a second chamber for damping motion of the valve member when a second fluid is present in the second chamber; means extending into the second chamber for admitting the second fluid therein; and means for draining the second fluid from the second chamber, wherein the admitting means connects the first chamber to the second chamber, the first fluid comprises fuel which flows through the first chamber, the admitting means has a fluid flow capacity which is substantially less than the flow capacity of the first chamber and the flow capacity of the admitting means is such that the second fluid within the second chamber substantially evaporates upon exiting the second chamber through the draining means.
