    • A fuel injection valve for internal combustion engines having, a valve member, which is axially displaceable in a valve body and which on one end has a valve sealing face with which it cooperates with a stationary valve seat in order to control an injection cross section, and having at least one valve spring, which urges the valve member in the direction of the valve seat and is braced on its other end on a stationary stop. To increase the spring force of the valve spring while the outer diameter remains the same, the windings of the valve spring, embodied as a helical spring, have a circular basic cross section (Y), which in a region pointing radially outward from the axis (X) of the valve spring has a ground face oriented parallel to the spring axis (X).

    • An arrangement and method for processing a signal field of sensor signals which originate from the individual sensor elements, for example photodetectors, of a plurality of sensor elements which are regularly spaced in an area and which are each surrounded by six adjacent sensor elements while forming a hexagonal structure. A differential amplifier compares a quantity representing the potential difference and a reference quantity forms a switching quantity (I.sub.Mo) on the output side. A switching comparator, on the input side, receives the switching quantity and, if this switching quantity exceeds the preselectable switching threshold, on the output side emits a switching pulse which causes the "off" switching condition. Four signal outputs 1, 2, 3, 4 as well as four signal inputs (I.sub.M1 I.sub.M2, I.sub.M3, I.sub.M4) are each connected with a signal input and a signal output of one of the four analog circuits assigned to the four next adjacent switchable resistors, one signal respectively being supplied to the four signal outputs which represents the switching quantity. A switching stage for forming the reference quantity takes into account the signals present at the four signal inputs.

    • A fuel injection valve for internal combustion engines that has a valve member which is guided axially displaceably in a guide bore of a valve body and which on an end toward the combustion chamber has a valve sealing face that cooperates with a valve seat face, formed on an end of the guide bore toward the combustion chamber, for controlling the communication between a high-pressure conduit in the valve body and at least one injection opening A diversion conduit in the valve member, by way of which diversion conduit the high-pressure conduit can be made to communicate with a relief chamber when the valve member has lifted from the valve seat face. Once the maximum opening stroke of the position of the valve member is reached, the diversion conduit is closed by a sealing face provided on the valve member, so that the entire supplied fuel quantity can attain injection.

    • 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.

    • A fuel injection nozzle for internal combustion engines has a nozzle body, a valve needle displaceably supported by the nozzle body, and a nozzle holder connected with the nozzle body and containing a spring chamber having a base. In the spring chamber are first and second closing springs arranged one after the other and acting on the valve needle one after the other. A first thrust pin penetrates the second closing spring. The first closing spring, which is farther away from the nozzle body, is supported at the base of the spring chamber and acts on the valve needle via the first thrust pin. The second closing spring is closer to the nozzle body and supported on a housing side and acts on the valve needle via discs and an intermediate bush. A second thrust pin penetrates the first closing spring and is arranged coaxially to the first thrust pin. The second closing spring is supported at the base of the spring chamber via the second thrust pin. The thrust pins have ends which face each other and carry heads with fingers which engage through one another and on which the closing springs are supported.

    • 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.
