Definitions

  • the invention relates to an engine, in particular a large diesel engine, with a plurality, arranged in at least one row behind the other cylinder and associated therewith, in at least one row successively arranged injection pumps, which are associated with at least a portion of the injection pump row continuous, stacked supply and disposal lines and their housing each containing a peripheral, connectable to the pump roomforcerauman für für für technik and from this radially outwardly outgoing, one above the other arranged connection channels, one of which communicates with the supply line and one with the disposal line.
  • the neutrrauman extract includes an undivided annulus, both of which go to the supply line and the disposal line leading connection channels. In this case, therefore, there may be a short-circuit flow between the two, closely spaced connection channels, so that an intensive flushing of the annular space with fresh fuel is omitted. The result of this is that the fuel in the annulus is too warm, which can lead to coking of the injector.
  • the document FR652624 discloses a fuel pump with a fuel supply and a fuel discharge and two annular storage spaces, wherein a first storage space with the fuel supply and a second is directly associated with the fuel discharge.
  • the consumerrauman emblem contains two superimposed annular spaces, each of which is assigned to the supply line or disposal line leading connection channel and the diametrically opposite in the connection channels peripheral region are interconnected by at least one overflow.
  • the cross section of the annulus connected to the relief line may be expediently larger than the cross section of the annular space connected to the supply line. This can be expected particularly favorable temperature conditions.
  • a further advantageous measure may be that the upper annular space of the superposed annular spaces is connected to the discharge line. This advantageously allows a very compact design.
  • the pump chamber can be connected to the upper annular space. With this, optimum injection temperatures can be achieved.
  • the overflow is offset from the circumferential position of the connection channels by exactly 180 °. This measure results in a virtually symmetrical arrangement with the greatest possible distance of the overflow from the connection channels, which has a favorable effect on the rinsing effect.
  • Main field of application of the present invention are provided with injection pumps large engines, such as large diesel engines, as they are used for marine propulsion or power plant drives, etc.
  • injection pumps large engines such as large diesel engines, as they are used for marine propulsion or power plant drives, etc.

  • the indicated in Figure 1 large diesel engine includes a plurality, here six, in series successively arranged cylinder 1, each of which an injection pump 2 is assigned.
  • the cylinders 1 associated injection pumps 2 are also arranged in series one behind the other. From each injection pump 2, an injection line 3 leads to at least one respectively assigned injection nozzle 4.
  • the injection pumps 2, which are arranged in series one behind the other, are supplied with fuel via a supply line 5 that runs through the entire pump row.
  • the excess fuel is removed via a likewise over the entire pump series continuous disposal line 6.
  • the supply line 5 comes from a supply pump not shown here and ends at the last injection pump 2 of the associated series.
  • the disposal line 6 starts at the first injection pump 2 of the associated row and leads to a fuel tank, not shown.
  • the supply line 5 and disposal line 6 are provided on the side facing away from the cylinders 1 side of the arranged next to the cylinders 1 injection pumps 2 and arranged in parallel one above the other.
  • the supply line 5 and disposal line 6 suitably contain from injection pump 2 to injection pump 2 leading pipe sections 5a and 6a, which, as best seen in Figure 2 can be connected to hereby aligned through holes 7, 8 a projection 9 of the pump housing of the injection pump 2 can be connected.
  • the supply line 5 has in addition to the leading from injection pump 2 to injection pump 2 pipe sections 5a another leading to the first injection pump pipe section.
  • the disposal line 6 on the other hand still has an additional, leading away from the last injection pump 2 pipe section.
  • the pipe sections 5 a of the supply line 5 and 6 a of the disposal line 6 are expediently connectable by means of a plug connection with the pump housing side projections 9.
  • the injection pumps 2 each have, as Figure 3 shows, a two-part pump housing with two cylindrical parts 10, 11 comprising each other.
  • the inner cylinder part 10 contains the pump chamber 12 which is bounded by a trained and drivable in a known manner stamp 13.
  • the outer cylinder part 11 contains the projection 9 provided with the through-bores 7, 8 belonging to the supply line 5 or disposal line 6.
  • the pump chamber 12 is associated with a circumferential fuelmerauman emblem, which is formed by provided in the region of the joint between the inner cylinder part 10 and the outer cylinder part 11 recesses.
  • This fuelplanrauman Mr consists of two superimposed annular spaces 14, 15 which are connected by superimposed, radial connection channels 16, 17 with the supply line 5 associated hole 7 and the disposal line 6 associated hole 8 and the one by a same circumferential position having, arranged one above the other connecting channels 16, 17 about diametrically opposite overflow 18 communicate with each other. Is appropriate the overflow 18 with respect to the connection channels 16, 17 offset by exactly 180 °.
  • the lower annular space 14 and the upper annular space 15 are expediently sealed off from one another by a sealing ring 19 arranged in a peripheral groove of the inner cylinder part 10 and resting against the inner circumference of the outer cylinder part 11.
  • the lower annular space 14 is connected via the associated connection channel 16 to the supply line 5 belonging to the bore 7 of the housing-side projection 9 of the outer cylinder part 10.
  • the upper annular space 15 is connected via the associated connection channel 17 to the disposal line 6 associated with hole 8 of the projection 9.
  • the connection channels 16, 17 can open directly into the associated bore 7 and 8 respectively.
  • the transitions are designed as inflow or outflow throttle 20 or 21.
  • the connection channels 16, 17 engaging hollow screws are provided, which are provided with the said restrictors forming radial bores.
  • the upper, communicating with the disposal line 6 annulus 15 has in the example shown a larger cross-section than the lower, communicating with the supply line 5 annular space 14 and is connected via a radial, controllable by the punch 13 bore 22 of the inner cylinder part 10 with the pump chamber 12.
  • the cross section of the lower, communicating with the supply line 5 annular space 14 corresponds approximately, preferably exactly the cross section of the overflow 18th
  • the stamp 13 associated, the pump chamber 12 forming bore of the inner cylinder part 10 is provided with a below the lowest position of the peripheral control edges of the punch 13 arranged, circumferential leakage groove 23, which avoids that fuel in the the injection pump 2 associated drive means containing engine compartment arrives.
  • This leakage groove 23 is connected by an oblique tap hole 24 with the upper, communicating with the disposal line 6 annular space 15, in which a lower pressure level is present, as in the lower, input side annular space 14.
  • the tap hole 24 passes radially within the sealing ring 19 over, so that resulting in a space-saving arrangement and a slim design.
