摘要： A fuel injection nozzle for internal combustion engines having a valve needle which enters an intermediate position in a retarded fashion and subsequently reaches its final position quickly. The valve needle is coupled in a positively-engaged manner with a supplementary body which as a result of its mass and/or hydraulically damps the movement of the valve needle over the course of a first stroke portion. At the end of this stroke portion, the supplementary body strikes a shoulder attached to the housing, whereupon the valve needle after the attainment of a notably higher fuel pressure, is separated from the supplementary body and translated quickly into its open position. In special cases, it is also possible for two supplementary bodies to be provided, which are uncoupled one after another from the valve needle and then again recoupled to the valve upon the closure of the valve. With an apparatus of this kind, the injection procedure can be adapted more freely than in the case of the known injection nozzles to a desired course.

摘要： To provide for coupling the injection needle of a Diesel injection valve with an inertia mass, and thereby provide for speed damping of the movement of the valve, the pressurized Diesel fuel is applied to a chamber (20,68) in the valve body (10,12,14), which slidably retains the needle valve element (18) at a location downstream of the inertia mass, the inertia mass subdividing the chamber into a spring or pressure chamber (20) and a damping chamber (68) forming a dead, or storage chamber for fuel, the inertia mass being slidable in the second chamber and the clearance between the inertia mass and the walls of the chamber forming a throttled connection duct so that, upon command to opening movement, the needle valve element will engage, after a short dead distance (v), the inertia mass (62) which must move against the flow resistance through the throttled connection upon shifting of fuel between the first and second chamber and thus damping the speed of operation of the valve element. The pressure differential at the two sides of the inertia mass will act on the entire cross-sectional area of the inertia mass, to provide high initial damping of the valve needle movement upon initiation of an opening stroke, while permitting a slim construction minimizing external diameter.

摘要： A fuel injection nozzle for internal combustion engines, provided with a valve needle and an induction coil, which sits in a spacer plate mounted between the nozzle body and the nozzle holder. The valve needle projects into the induction coil and acts upon the magnetic domain of the induction coil by the action of its movement, whereby a signal dependent on the velocity of the needle is produced. The induction coil is provided with laterally disposed contact prongs which are connected with extended connecting wires by means of a weld or solder joint. The connecting wires lead through boreholes in the nozzle holder. The injection nozzle is distinguished by an especially small electrical line resistance, and by the fact that, with appropriate dimensioning and construction of the ends of the connecting wires, which carry the extended connection contacts, there will be no special contact measures necessary for disassembly.

摘要： The injection pump has a pump piston driven with a constant stroke which pumps fuel at injection pressure to an injection nozzle so long as an electrically actuated overflow valve blocks the flow of the fuel overflowing via an overflow conduit to a low-pressure chamber. The overflow valve is a needle valve, the valve needle of which, opening inward toward a pressure chamber that can be placed under injection pressure, by means of a conical closing surface radially defining a needle tip controls a valve seat that widens conically toward the pressure chamber. The cone angle of the closing surface is larger than the cone angle of the associated valve seat and the closing surface forms a sealing edge, the diameter of which is equal to or only slightly smaller than the guide diameter of the guide shank on the valve member. In a preferred embodiment, the needle tip of the valve member has an external contour on its end, adjacent to the closing surface, which directs the fuel flow and reinforces the opening movement. The injection pump is particularly suitable for high-pressure injection in Diesel engines, in order to attain an exact electrical control of the supply onset and supply quantity, if a reservoir chamber defined by a deflecting piston is connected to a high-pressure chamber that includes the pump work chamber.

摘要： A fuel injection nozzle for internal combustion engines having an inwardly opening valve needle (I nozzle) is proposed, in which an induction coil is disposed in the closing spring chamber, the induction coil together with an armature influenced by the valve needle forming a signal transducer for a measuring appliance for detecting the onset of injection and further data, as needed, of the injection process. The air gap of the magnetic circuit of the induction coil is formed between the armature and a coil, toward which the armature moves during the opening stroke of the valve needle. As a result, it is possible to attain a small initial air gap and a large change, in terms of percentage, in the air gap. The apparatus according to the invention is particularly suitable for measuring circuits in which a direct voltage is applied to the induction coil and the voltages induced as a result of the air gap changes in the induction coil are superimposed on the applied direct voltage.

摘要： Fuel injection nozzle for internal combustion engines includes a first closing spring which acts continuously on the valve needle by means of a central pressure pin and, in addition, a second closing spring which acts continuously on the valve needle by means of a pressure piece after covering the distance of an initial stroke. The pressure piece is supported at the nozzle body by means of an intermediate bush during the initial stroke. The initial stroke is limited by means of the shoulders at the valve needle and the intermediate bush, whereas the total stroke is limited by means of the shoulders at the intermediate bush and the intermediate disk. Accordingly, the initial stroke can be adjusted very accurately to a desired magnitude merely by means of grinding the valve needle and does not change during the assembly of the injection nozzle.

摘要： An injection nozzle for internal combustion engines has an electrical needle motion sensor, having a cable leading to an evaluation device. To dispose the terminals of the contact lugs of the needle motion sensor and the contact ends of the individual wires of the cable in such a way that they are shake-proof, relieved of tensile strain and protected against splashing water, they are encapsulated in a two-piece insulating shaped part, which is fixed in a recess of the holder body of the injection nozzle. The soldered terminals rest on support bases of pockets in the inner insulating shaped part, and the adjoining parts of the individual wires are bent back and guided in a U around retaining protrusions. The insulating shaped parts and the sheathed cable are fixed by a cover strip or by pins. The preferred field of application is injection nozzles for Diesel engines.

摘要： A fuel injection nozzle for internal combustion engines, having a valve needle arranged to open toward the outside and said valve needle further connected with a piston which defines a fuel-filled damping chamber, which communicates with the flow path of the fuel only via a throttle conduit during the opening stroke of the valve needle. The damping chamber is formed in a cap which is placed onto the piston. As a result, jamming of the elements in the radial direction is avoided. Furthermore, the piston may be embodied by the valve needle per se, resulting in a simple and space-saving construction. By means of the appropriate embodiment and supporting of the cap, the damping effect can be limited dependent on the stroke and/or the travel speed of the valve needle.
