Definitions

  • the invention relates to a pump arrangement for High pressure fuel supply at Fuel injection systems of internal combustion engines, especially with a common rail injection system a pump housing, which comprises several pump elements, in which fuel is subjected to high pressure, the high pressure fuel over a High pressure duct system from the individual pump elements to a common high-pressure connection bore is promoted.
  • the invention is therefore based on the problem that High-pressure duct routing between the individual To optimize pump elements and the high pressure connection. In particular, voltage peaks in the Borehole intersections can be minimized.
  • the problem is with a pump arrangement High pressure fuel supply at Fuel injection systems of internal combustion engines, especially with a common rail injection system a pump housing, which comprises several pump elements, in which fuel is subjected to high pressure, the high pressure fuel over a High pressure duct system from the individual pump elements to a common high-pressure connection bore is promoted, solved in that the high pressure duct system several High pressure channels includes that with the pump elements in Connected and arranged on a different level are as the common high pressure connection hole in the the high pressure ducts meet.
  • the high pressure channels in one level can be used for each High pressure valve the same parts are used.
  • the common high pressure connection hole in a different level than the high pressure ducts High pressure channels eccentric to the Hit the high pressure connection hole.
  • the Center lines of the high pressure ducts do not match the Cut the center line of the high pressure connection hole. Thereby become the stress peaks in the intersections reduced.
  • This has the advantage that a Fatigue strength of the pump housing even at pressures of up to up to 2000 bar is guaranteed.
  • the Pump arrangement according to the invention the advantage that it can be produced inexpensively.
  • Another special embodiment of the invention is characterized in that at least one of the High pressure channels in the outlet of the high pressure connection bore flows out, which is spherical. Through the spherical formation of the high pressure connection bore can Bore intersections realized with larger angles than with bores made with conventional drills be generated. There are also additional notches in the outlet the high pressure connection hole avoided.
  • Another special embodiment of the invention is characterized in that the high pressure channels Penetrate blind holes off-center. This will Tensions reduced.
  • the present invention generally provides the advantage that large diameter differences between the High pressure ducts and the high pressure connection hole fluidically cheap can be realized.
  • the pump arrangement according to the invention can for example be a radial piston pump.
  • Radial piston pumps are especially in common rail injection systems Fuel supply used for diesel engines.
  • there "common rail” means “common line”, “common rail” or “common rail”.
  • common rail means "common line", “common rail” or “common rail”.
  • the pump elements of a radial piston pump can be from cylinder spaces arranged radially to a drive shaft are formed, in which a piston back and forth is movably received.
  • the pistons are used Fuel in the cylinder rooms at high pressure apply.
  • the high pressure fuel is then a high pressure duct system and a High pressure connection in the common manifold promoted.
  • a high-pressure pump is shown in section in FIG.
  • a pump housing part 2 In a pump housing part 2 are three blind holes 3, 4 and 5 shown, which holes not shown are each connected to one of the pump elements (see also Figure 2). Perpendicular to blind holes 3, 4 and 5 run two high pressure channels 6 and 7.
  • the High-pressure duct 6 connects the blind holes 3 and 4 with each other and penetrates a high pressure connection hole 8, whose diameter is larger than the diameter of the High-pressure channels.
  • the high pressure channels 6 and 7 run in one plane, the corresponds to the drawing level in FIG. 1. Like from the Sectional representations of Figures 2 and 3 can be seen, extends the high pressure connection bore 8 in one Plane parallel to the high pressure channels 6 and 7. The distance of the parallel planes is chosen so that the High pressure channel 6, the high pressure connection bore 8 in penetrates essentially tangentially in FIG see that the outer surface of the high pressure channel 6th on the one hand the lateral surface of the high pressure connection bore affected and on the other hand almost perpendicular to the Shell surface of the high pressure connection bore hits.
  • the high pressure channel 7 connects the blind hole 5 with the High-pressure connection bore 8.
  • the high-pressure duct opens 7, as can be seen from the section shown in FIG. 3, off-center and essentially tangential in the High pressure connection hole 8.
  • the high pressure channels 6 and 7 the blind holes 3, 4 and 5 also substantially penetrate tangentially and off-center.
  • the High-pressure connection bore 8 has a spherical outlet 11.
  • the embodiment shown in Figure 1 has an outlet 10 which tapers to an angle of approx. 120 ° and from comes from a normal drill tip.
  • the angle is ⁇ between the high pressure channel 7 and the outlet 10 of the High pressure connection hole 8 approx. 60 °.
  • the Angle ⁇ between the high pressure channel 7 and the outlet 11 the high pressure connection bore 8 is approximately 75 °, which in Terms of the level of tension at the Borehole intersection and fluidically favorable.
