<p>The purpose of the invention is to improve the adjustment accuracy and function of fuel injection valves as claimed and reduce the manufacturing costs. For an electromagnetically operated fuel injection valve (1) for four-stroke engines, the invention provides a highly precise mutual arrangement of the outlet aperture (14), the valve seat (13) and the guide path (22) and thus improves the operational accuracy and wear resistance of the fuel injection valve in that a separate guide ring (21) is spring-loaded and held floatingly in the longitudinal drilling (11) at a radial distance from the wall (10), so that the holding forces are greater than the forces acting on the guide ring (21) during the operation of the fuel injection valve. The invention is intended especially for fuel injection valves of vehicle engines.</p> |
