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.
