摘要： The method according to the present invention for manufacturing a magnet coil for a valve is characterized in that first a metal base element (2) of the valve is made available, then an electrically insulating winding support (50) is mounted on the outer wall of the base element (2), and lastly a winding (4) of the magnet coil (1) is introduced into the winding support (50). Such a configuration of a magnet coil is suitable particularly in fuel injection valves which are used in mixture-compressing, spark-ignited internal combustion engines, but also in all other solenoid valves.

摘要： The present invention relates to an electromagnetically actuatable valve having a longitudinal valve axis (3), having an electromagnetic circuit (1, 2), having a movable actuating member (25), that cooperates with a fixed valve seat (23) for opening and closing the valve, and having an outlet opening (8) that is configured downstream of the valve seat (23). The actuating member (25) is executed in a bowl, trough, or saucer shape, having an actuating leg (26) and a supporting leg (27) that is configured so as to be substantially perpendicular to the former. The actuating leg (26), as a movable part of the actuating member (25), cooperates with an upper layer (15) of atomization disk (12), so as to form a sealing valve. The valve is especially well-suited for use as a fuel injector in an internal combustion engine, especially in a mixture-compressing, spark-ignition internal combustion engine.

摘要： A fuel injection port 21 formed in a seat 20 is opened and closed by a movable valve 14 supported by a flat spring 16. The movable valve 14 is biased by an elastic force of a coil spring 26 in a direction that closes the fuel injection port 21. When electric power is supplied to a solenoid coil 4, the movable valve 14 is moved to a direction that opens the fuel injection port 21 as a result of an electromagnetic attraction force between a magnetic circuit M for generating an electromagnetic attraction force and the movable valve 14. Air gaps G0, G1 and G2 are formed within the fuel injection port and permeance ratios between the air gaps may be set to optimal valves.

摘要： An injector coil body assembly with upper and lower coil bodies is held together with a spring type press fit instead of welding. The coil bodies are made with generally tubular connecting portions telescoped together around the magnetic coil. The downwardly open tubular lower portion of the upper body is longer and slightly smaller than the connecting upwardly open tubular upper portion of the lower body so that the lower portion of the upper body fits into the upper portion of the lower body. A longitudinal slot in the upper body lower portion allows the lower portion to spring in slightly upon insertion into the lower body upper portion so that the upper and lower bodies are retained in assembly by a spring biased press fit. The press fit holds the telescoped portions in close contact, providing an efficient path for carrying the magnetic flux of the coil.

摘要： A fuel injector for an engine includes a continuous endoskeletal injector tube enclosing an imperforate continuous passage for fuel flow from an inlet end to an outlet end of the tube. A valve seat, injection valve, tubular magnetic pole, biasing spring and adjusting sleeve are mounted within the tube, optionally with other elements, all being exposed to fuel in the passage defined by the tube. A solenoid coil and a magnetic body together with mounting components and seals are mounted on the exterior of the tube where they are protected from exposure to the fuel, which is restricted to passage within the continuous tube. The body, pole and armature form a magnetic flux concentrating path operative to attract the armature to the pole and open the valve when the coil is energized. The solenoid coil may be preassembled with its connector in a body forming a separate coil assembly for subsequent installation on the injector tube. During assembly, the tubular pole may be adjusted to set the desired stroke of the injection valve prior to fixing the pole in the tube. Various other features are also disclosed.

摘要： An intake manifold assembly includes an improved air intake manifold receiving novel side feed fuel injectors. A fuel rail is integrated as a common part defining a common fuel passage integral with the air intake manifold. The common fuel passage supplies the side feed fuel injectors through openings that are spaced away from the injector nozzles toward an opposite connector end of each injector. The injector design concentrates an actuating coil, armature and nozzle valve in a lower or nozzle end of the injector. The fuel is fed from the side feed opening through an axially centered fuel passage that extends through the coil and the associated armature to the injection valve in a manner identical to corresponding top feed injectors. Thus, the performance advantages of top feed injection systems are provided while gaining the reduction in cost attributable to elimination of the separate fuel rail and subassembly. Various arrangements are disclosed for retaining the injectors in the manifold assembly.

摘要： In a method for measuring lift of a valve needle and for adjusting the volume media flow of a valve, easily focused, high-energy radiation is used, which permits a contact-free measuring operation. The high-energy radiation is directed at the valve-closure member that is permanently joined to the valve needle in the installed valve. By performing a differential measurement, thus a measurement in both end positions of the valve needle, the lift of the valve needle can be determined and, thus, corrected. The measurement is performed on a dry valve. The method is particularly suited for electromagnetically actuated fuel-injection valves of mixture-compressing internal-combustion engines having externally supplied ignition.
