摘要： The invention relates to an injection valve (1) comprising a booster piston (23), said piston delimiting a pump chamber (22) and a booster chamber (29). A valve (14) is provided in the inlet to the chamber (22). The valve is configured as a 3/2-way valve and controls the pressure in the pump chamber (22). The pressure in the pump chamber (22) is converted into a correspondingly increased pressure in the booster chamber (29) and in an injection chamber (34) containing an injection needle (6), by means of the booster piston (23). The use of the valve (14) allows a precise control of the injection times.

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： A high pressure injection system comprises at least one fuel high pressure accumulator, a control chamber and a valve, in addition to an injection valve having a valve needle and a control piston. The control chamber is connected to the high pressure accumulator by means of an inlet throttle and to the valve by means of an outlet throttle. The control chamber controls the movement of the control piston and the valve needle connected thereto. To this end, flow conditions of the fuel flowing into and out of the control chamber are regulated by means of the inlet throttle and the outlet throttle. The inlet throttle is configured as a multi-stage throttle.

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： Located between the frustoconical needle tip and the cylindrical needle shank of a nozzle needle of a fuel injection valve is a frustoconical needle portion, into which is introduced a peripheral groove. Through this kind of arrangement damping is capable of being set, depending on the position of the groove, during the axial movement of the nozzle needle.
