摘要： With prior art electromagnetically operated valves with a core on which a coil magnet is wound and an armature which acts via a connecting tube on a valve closure element, welding or brazing the components together requires a great deal of space. In addition, this procedure does not always produce a reliable join. With the new valve, laser welding of the components at a point of reduced cross-section, e.g. point 40, not only reduces the size of the valve but also gives a reliable, crack-free join. This valve design is particularly suitable for fuel-injection valves.

摘要： In existing electromagnetically operated valves with a fuel-inlet pipe acting as the core of a coil magnet surrounding it, at least part of the valve is surrounded by a plastic shell with an integrally moulded connector plug. Different valve injection-moulding tools are necessary, however, for different designs of electric plug. With the new valve, the electric plug (21) is injection-moulded at the same time as the coil magnet surround (4) is moulded, thus forming an independent injection-moulded plastic part. Only one valve injection-moulding tool is necessary for different designs of electric plug, thus giving greater assembly-line flexibility. The valve is suitable for use in fuel-injection systems.

摘要： The purpose of the invention is to improve the accuracy of adjustment and function of fuel injection valves as described in the claim and to reduce manufacturing costs. In an electromagnetically operable fuel injection valve (1) for four-stroke engines, the invention provides a high-precision mutual arrangement of the outlet aperture (9) of the nozzle (5) or the valve seat (8) and the guide path (14), thus improving the operational precision and the wear resistance of the fuel injection valve in that a separate guide ring (7) is held in the longitudinal drilling (13) with a radial clearance by a welded joint (2). The invention is designed especially for fuel injection valves of motor vehicle engines.

摘要： In known electromagnetically actuated valves with axial fuel feed, the opening stroke of the valve closing element is limited by an annular stop device. If the valve needle is skewed, however, only part of the stop makes contact, and therefore the injected volume is not metered with sufficient accuracy. The new stop device makes it possible to control the opening stroke of the valve closing element whether or not the valve needle is skewed. When the valve is open, the new stop rod (40), which is concentric with the longitudinal axis (4) of the valve, touches the valve closing element (14), thereby limiting its opening stroke. The stop rod (40) is mounted in the flow hole (21) of the core (1) by means of the sliding sleeve (22). The design of the stop device is particularly suited to fuel injection valves.
摘要翻译：在具有轴向燃料供给的已知的电磁致动阀中，阀关闭元件的打开行程由环形止动装置限制。然而，如果阀针歪斜，则只有部分止动件接触，因此注射体积没有足够的精度计量。新的停止装置能够控制阀关闭元件的打开行程，无论阀针是否歪斜。当阀打开时，与阀的纵向轴线（4）同心的新的止动杆（40）接触阀关闭元件（14），从而限制其打开行程。止动杆（40）通过滑动套筒（22）安装在芯体（1）的流动孔（21）中。止动装置的设计特别适用于燃油喷射阀。

摘要： The aim of the invention is to provide, in an electromagnetically operated fuel-injection valve (1) for an internal-combustion engine, a high-precision disposition of the outlet aperture, valve seat and guide cylinder relative to each other, thus increasing the operating precision and reducing the wear of the fuel-injection valve. This is achieved by virtue of the fact that the valve seat body (5) includes the guide cylinder (7), the valve seat (8) and the outlet aperture (9), located integral with and inside the valve-seat body near its axis. The invention is intended in particular for motor-vehicle fuel-injection units.

摘要： In known solenoid valves with a core (1) surrounded by a magnetic coil (3) and with an armature (30) which acts on a valve closure body by means of a connecting tube (28), the connection between the connecting tube and the hard valve closure body (35) is made by welding or soldering. However, the connection is not always safe and reliable. In the new valve, on the contrary, the metallic valve closure body (35) is first provided with a spot weld (40) which is then welded to the metallically softer connecting tube (28) by a second spot weld (41) until the at least partially surrounding weld seam (39) which ensures a safe and reliable connection is formed between the valve closure body (35) and the connecting tube (28). The configuration of the valve is particularly suitable for injection valves in fuel injection installations.

摘要： In prior art fuel-injection valves, the valve-needle stroke can be adjusted for example by grinding down one end of the valve-nozzle body or by varying the penetration depth of the valve-seat body inserted in a longitudinal aperture in the valve-seat support and subsequently rigidly secured to the valve-seat support. This method of adjustment is not possible with assembled valves however. If the valve-seat body is pressed into the longitudinal aperture, there is a danger of clip formation. In the new fuel-injection valve, a valve assembly comprising the valve-seat body (18) and the perforated body (22) joined to it is inserted in the longitudinal aperture (3) in the valve-seat support (1) and rigidly secured to it, the depth of insertion determining the initial setting of the valve-needle stroke. Exact adjustment of the needle stroke can be done with the assembled valve by bending the part of the valve located between the points of attachment (24, 30) of the perforated body (22) to the valve-seat support. The fuel-injection valve proposed and the method for its manufacture are particularly suitable for use in fuel-injection systems in mixture compressing spark ignition engines.

摘要： The device comprises a tensioned wire (16, 64) which elastically closes a valve (18) which opens outwardly. The prestress tension of the wire (16, 64) depends on the current of an electric circuit (52) which flows across an electric resistent element (16, 82) incorporated in the fuel injection nozzle. The resistent element may be comprised of the wire (16) itself or of the coil (82) of an electromagnet (70) of which the armature (68) is coupled with the tension wire (64). Thus, the opening pressure (pö) of the fuel injection nozzle and its operation may be easily controlled and follow a predetermined law.

摘要： Prior art fuel injection valves make use of valve needles consisting of a tubular armature, a sleeve-like needle section acting as a connector and a valve closure. The individual components are assembled by material seaming processes, e.g. welding or soldering. The novel fuel injection valve is characterised in that use is made of a valve needle (18), the individual components of which, e.g. the valve needle section (19) and the valve closure (24) are secured together by a non-material seaming process. Ideally there are only pressed joints on the valve needle. The fuel injection valve is especially suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.

摘要： In prior art fuel-injection valves, fuel filters are inserted into the fuel-inlet pipe where they are secured in place. These fuel filters ensure that certain constituants which could, by virtue of their particle size, block or damage the valve are filtered out of the fuel fed to the valve. Foreign bodies inside the valve which originate from components inserted into the valve, from wear of stop surfaces or from production-related burring are not filtered out however, resulting in the danger of blockages or leakage at the valve seat. The valve needle (18) proposed, for a fuel-injection valve for instance, has a filter element (20) integrated in or on it. The function of this filter element (20) is to keep any particles or other impurities inside the valve upstream of the valve seat (30) away from the valve seat (30) and hence avoid blockages or leakage at the valve seat (30). The valve needle proposed is particularly suitable for use in injection valves in fuel-injection systems for mixture-compression external-ignition-combustion engines.
