  • connecting lines 15 are provided, the lower ends of which are electrically conductively connected to the ends of the connecting lines 10, 11.
  • This connection can be made by soldering or welding or can be designed as a detachable or non-detachable plug connection.
  • An annular seal 16 seals the foot part of the plug part 14 against the through hole 8.
  • the through hole 8 is closed with an end plug 18 carrying an annular seal 17.
  • the plug part 14 protrudes upwards and is guided through an opening 19 of the valve cover 20, an annular seal 21 providing the required sealing.
  • Plug pins 22, which are electrically connected to the connecting lines 15, protrude from the head part of the plug part 14.
  • a connector plug 23 can be placed, which has the sockets 22 assigned to the connector pins 22 and from which a connecting cable 25 leads away.
  • the embodiment just described has the advantage that no special precautions have to be taken in the cylinder head of the engine.
  • the injection nozzles are clamped onto the cylinder head by means of the flanges 3 and then the valve cover 20 is put on, the head parts of the elongated plug parts 14 being guided through the openings 19 of the valve cover 20.
  • a connector part 14 ' is provided, which in principle is the same as the connector part 14 of Fig. 3, but is shorter and is inserted into the through hole 8 so that it is downwards, i.e. protrudes in the direction of the cylinder head 4. Therefore, the plug 18 closes the through hole 8 at its upper end. At its free end, the connector part 14 'is in turn provided with connector pins 22.
  • the connector pins 22 are assigned a connector 27 which is stuck in the cylinder head 4.
  • a blind bore 28 is formed in the cylinder head 4, which is coaxial with the through bore 8 when the injection nozzle is inserted.
  • a transverse bore 29 runs transversely to the blind bore 28.
  • the plug 27 can be inserted into this from the outside.
  • a locking and centering part 30 is arranged in the bottom region of the blind bore 28. This part 30 has a centering web 31, which cooperates with a nose 32 of the plug 27 to ensure its correct angular position.
  • a resilient locking web 33 holds the plug 27 in its position in which the contact sockets 24 are precisely aligned with the pins 22 of the plug part 14 '.
  • An annular seal 34 at the lower ends of the connector part 14 'and an annular seal 35 on the connector 27 ensure that the vapors and oil mist in the area above the cylinder head 4 can not come to the contacts of the connector or to the outside.
  • FIGS. 5 and 6 Another embodiment of the invention is shown in FIGS. 5 and 6.
  • the ends of the connecting lines 10, 11 are provided in the through bore 8 with bushes 36 which extend in the axial direction and are fixed in an insulating insert 37.
  • the insulating insert 37 is held firmly in the through bore 8 by suitable means.
  • the sockets 36 advantageously extend over the length of the insulating insert (see FIG. 6) and can be plugged in both from above and from below.
  • pins or plug-in tabs projecting upwards and / or downwards can also be provided in place of the bushings 36 or that bushings and pins are combined. This generally also applies to the embodiments described above.
  • a fixed connector counterpart can be provided on the cylinder head.
  • the plug connection is made automatically from below, similarly to FIG. 4.
  • a plug connection can be made using a suitable connector, similar to FIG. 3.
  • the unused side of the insulating insert 37 can, as shown in Fig. 3 and 4, by means of a plug 18 or the like. be sealed.
  • a combination of the designs according to FIG. 3 or 4 with the design according to FIGS. 5 and 6 is possible, which means that the plug part 14 or 14 'can be plugged on both sides.
  • the plug part 14 has an annular flange 38 near its upper end and on the inside of an annular collar 39 which extends downward from the valve cover 20, a circumferential cut 40 which is open at the bottom is formed.
  • a soft ring seal 41 can be inserted, which is supported downwards on the ring flange 38.
  • This sealing arrangement also effectively prevents the passage of spray oil through the opening 19 of the valve cover 20.
  • the connector plug 42 engages deep into the bore of the ring collar 39 and thereby additionally protects the actual contacts from contamination.
  • the annular flange 38 projects from a tube 43, preferably a metal tube, which surrounds an insulating inner part 44 with the connecting lines 15 in a protective manner.
  • FIG. 8 differs from the one just described in that the plug part 14, which is made of plastic, has no outer protective tube and the ring flange 38 is designed as a metal disk cast or pressed in with the plug part 14. Furthermore, for better support of the seal 41, a further metal disk 45 is inserted into the cut in the ring collar 39.
  • the outer shell of the plug part 14 is a metal tube which merges at the top via a conical transition region 46 into an end piece 47 of larger diameter.
  • the contact pins and / or sockets sit in this end piece 47.
  • a metal bushing aligned with its lifting direction A, which forms an annular collar 48.
  • a flexible, cylindrical sealing lip 50 made of hot oil-resistant elastomer is connected to a lower, inwardly bent edge 49 of this bushing 48 and extends upwards inside the bushing 48 by vulcanization.
  • the upper end region of this sealing lip 50 is pressed against the end piece 47 of the plug part 14 by means of an annular tubular spring 51. This results in an effective seal that also allows larger manufacturing tolerances.
  • through hole 8 Although only one through hole 8 is shown in the flange 3 in the drawing, two such through holes with corresponding electrical connections can also be provided, for example, if required.
  • the number of connecting lines or contacts depends on the nozzle design. If the nozzle only contains a needle stroke sensor, two connecting lines will generally be sufficient. This also applies if the nozzle contains only one control magnet, but no needle stroke sensor. However, it is possible for the quantity adjuster to be assigned an electrical feedback device, so that - with the simultaneous use of a needle stroke sensor - at least six connecting lines are required.
