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： A unit for delivering fuel from a supply tank to an internal combustion engine, having a disklike impeller driven to revolve in a pump chamber, on whose circumference a number of blades are disposed, and having at least one supply conduit, disposed in the region of the impeller blades and open toward the impeller, in a chamber wall defining the pump chamber on the face end and axially adjoining the impeller, which supply conduit extends via a split ring around the pivot axis of the impeller from an inlet opening into the pump chamber to an outlet opening from it. In order to assure that sufficient fuel can be aspirated unthrottled in the presence of gas bubbles in the fuel, in particular when the fuel is hot, the supply conduit is embodied in the region of the inlet opening as larger by a factor of 2 than the usual supply conduit cross section; the cross section of the supply conduit then decreases continuously, beginning at the inlet end, forming a compression conduit.

摘要： A fuel injection nozzle having an outwardly opening valve needle to which a piston is connected and on which a cap is mounted. The cap encloses a damping chamber, which communicates in a throttled manner, via the play between the piston and the cap, with the flow course of the fuel. Oriented toward the cap is a blocking shoulder attached to the housing, which shoulder restrains the cap, after an undamped pre-stroke (h.sub.v), relative to the valve needle, which continues to move, its continued movement being damped thereby. A spring acts via a spacer body upon the cap, the spacer body keeping the cap at a distance from the blocking shoulder corresponding to the pre-stroke (h.sub.v) in the closing position of the valve needle. As a result, the prescribed set-point value of the pre-stroke (h.sub.v) can be adhered to very precisely.

摘要： In a fuel supply system for an internal combustion engine, significant parameters such as fuel pressure and fuel flow rate are determined continuously from measured variables with the aid of an observer. These variables which have been determined are used to achieve fuel delivery performed with regard to a requirement, the control operations being carried out as a function of requirements of the internal combustion engine by the control unit itself.

摘要： A fuel injection nozzle for internal combustion engines is proposed, which includes a valve needle stressed by a closing spring and a damping device to partially damp the opening movement of the valve needle. The damping is effected in accordance with the stroke frequency, the stroke length of the valve needle, or both, or the quantity of fuel throughput per injection cycle, and the damping effect is preferably variable automatically by shifting the time of the onset of damping relative to the onset of injection. As a result, an adaptation of the damping effect to the operating state of the engine at a particular time can be attained which substantially meets the ideal parameters for such damping.

摘要： A fuel injection nozzle for internal combustion engines, having an outwardly opening valve needle, which is connected with a piston upon which a damping cap is placed, which is supported on a shoulder integral with the housing. In the damping cap, a damping chamber is formed, which communicates via a throttle conduit with the flow path of the fuel. The diameter of the piston is smaller than the cross section enclosed by the valve seat, as a result of which an annular shoulder is attained, on which the unthrottled fuel pressure acts upon the valve needle in the opening direction. This disposition has the advantage that at lower rpm and smaller fuel quantities, the valve needle can be effectively braked even up to relatively long needle strokes, without the injection duration becoming overly long at higher rpm.
