A valve for metering a fluid is described, which is used, in particular, as a fuel injector for internal combustion engines, including an electromagnetic actuator and a valve needle actuatable by the actuator, an armature of the actuator being guided on valve needle, a stop element which limits a movement of the armature relative to the valve needle being situated on the valve needle, and the armature including a spring receptacle which is open toward the stop element and in which a spring supported on the stop element is inserted. The valve needle is guided via the armature and/or the stop element along a longitudinal axis of a housing. Furthermore, as viewed along the longitudinal axis, a length of the spring receptacle is smaller than a spring length of the spring in the non-actuated initial state.

Valve for metering a fluid

A fuel injection valve, in particular a high-pressure injection valve for the direct injection of fuel into the combustion chamber of a compressed mixture, externally ignited internal combustion engine, has in a guide and seat area provided at the downstream end of the valve which area is formed by three disk-shaped elements. A swirl element is nested between a guide element and a valve seat element. The guide element, which can move radially in the assembled valve and which has an inner guide opening, serves to guide an axially movable valve needle which extends through it, while a valve closing section of the valve needle acts in concert with a valve seat surface of the valve seat element. The guide element is spring-loaded through a compression spring which acts upon it.
