摘要： A valve assembly includes a valve body having a cavity with a fluid inlet portion and a fluid outlet portion, a valve needle axially movable in the cavity to control a fluid flow through the fluid outlet portion, a guide coupled to the valve needle, an electro-magnetic actuator unit configured to actuate the valve needle and comprising an armature axially moveable in the cavity relative to the valve needle, the armature configured to be coupled to the guide when the valve needle leaves the closing position and configured to mechanically decouple from the guide due to its inertia when the valve needle reaches the closing position, and an armature spring coupled to the armature to provide a force to the armature contributing coupling the armature with the valve needle. A block-shaped stop element axially adjacent the armature and coupled to the valve body limits the axial movement of the armature.
