摘要： A method for producing a hole in a body, especially an injection hole in a fuel injector is disclosed. The hole (L) is first produced by a percussion boring process or a trepanation boring process using a laser. The percussion boring process lasts less than 3 seconds. The trepanation boring process lasts less than 10 seconds. After percussion boring or trepanation boring a smoothing step is carried out by forcing a medium that is mixed with abrasive particles under pressure through the hole until any roughnesses of surfaces (F) of the body that form the hole (L) are substantially removed.

摘要： A device for transmitting a deflection of a piezoelectric actuator to a movable tappet includes a pressure chamber between the piezoelectric actuator and the tappet. The pressure chamber is substantially formed by two mutually parallel diaphragms having effective radii of different lengths. The diaphragm with the longer radius is associated with the piezoelectric actuator and the diaphragm with the shorter radius is associated with the tappet. Therefore, upon a deflection of the first diaphragm by the piezoelectric actuator, the second diaphragm is deflected by a greater distance toward the tappet. A controller with an actuator having a controllable length is also provided.

摘要： The fuel injector has a housing that is formed from at least one nozzle tension nut, a first injector module and a second injector module. The first injector module and the second injector module adjoin one another and are disposed in the nozzle tension nut. A fuel high-pressure bore is led through the first injector module and the second injector module. A fuel return bore is disposed in the housing. Contact surfaces between the injector modules form a first gap that adjoins the high-pressure bore. Contact surfaces between the nozzle tension nut and the injector modules form a second gap that is connected to the first gap. The return line adjoins the second gap for the discharge of fuel that has entered the second gap from the high-pressure bore via the first gap. The fuel injector is such that the second gap is sealed off relative to the surroundings of the fuel injector.

摘要： An actuator is operatively connected to a closing member via a tappet. The closing member is introduced in a valve chamber and forms, with a conically tapering valve seat as part of a servovalve, a seal resistant to high pressure. The cross section of the closing member is configured to be mushroom-shaped, a closing head being in the form of a part-sphere and having a central flattening, with the result that the tappet has an enlarged bearing surface. A stem of the closing member is surrounded by a valve spring. The closing member is preferably shaped out of a solid sphere.

摘要： The injection valve has a control valve with a control chamber in which a closing member is disposed. The closing member is pressed against a corresponding sealing seat by a pressure (e.g. fuel pressure) in the control chamber. The closing member merges into a rod that passes through a drain hole and is connected to a spring plate. The spring plate is preloaded against the housing by a compression spring in such a way that the closing member is pressed against an associated sealing seat. The closing member can be raised from the sealing seat by an actuator piston which rests against the spring plate.
