More Information
Summary:The invention relates to a valve for dosing fluid, in particular a fuel injection valve for an internal combustion engine, comprising an armature of an electromagnetic actuator and a valve needle which can be actuated by the armature and which serves to actuate a valve closing body, which interacts with a valve seat surface to form a sealing seat, the armature being movably guided on the valve needle. According to the invention, at least one stop element is provided which is arranged stationary on the valve needle and limits a relative movement between the armature and the valve needle in relation to the actuation of the valve needle, and at least one armature free-travel spring is provided which is supported at least indirectly on one side on the armature; the other side of the armature is at least indirectly supported on the stop element, and the armature free-travel spring surrounds the valve needle. According to the invention, the stop element has a spring receptacle into which thearmature free-travel spr
