Definitions

  • the invention relates to a radial piston pump unit for generating high fuel pressure in fuel injection systems of internal combustion engines, in particular in a common rail injection system.
  • DE 198 48 035 AI discloses a radial piston pump for the generation of high-pressure fuel in fuel injection systems of internal combustion engines, in particular in a common rail injection system.
  • the radial piston pump has a housing in which a drive shaft is guided.
  • the drive shaft has an eccentric section on which a cam ring is guided.
  • a plurality of pump pistons are preferably supported on the cam ring and are radially longitudinally movable in the pump housing with respect to the drive shaft.
  • a suction valve and a pressure valve are assigned to each pump piston. Fuel from the low pressure range is fed to the pump piston via the suction valve. After the pressure builds up, the compressed fuel is discharged via the pressure valve.
  • Such a radial piston pump is usually preceded by a fuel feed pump which supplies the fuel from the fuel tank to the high-pressure pump.
  • the fuel feed pump is usually driven by an electric motor or via the camshaft. With the camshaft drive, the pre-feed pump can sit directly on the camshaft or be driven by a belt. Due to the limited space in the engine compartment, it is necessary to make the high-pressure fuel pump and the pre-feed pump as compact as possible.
  • DE 197 36 160 AI therefore proposes to arrange the fuel feed pump on or in the pump housing of the radial piston pump and via the drive shaft of the radial piston pump drive.
  • a clutch is interposed between the drive shaft of the radial piston pump and the shaft of the pre-feed pump.
  • the invention is characterized in that the radial piston pump has a drive shaft which has an overhung end region with a tooth profile for receiving a fuel feed pump.
  • the advantage of the floating bearing is an extremely compact design of the radial piston pump unit, since a third bearing of the drive axis is saved.
  • the toothed profile means that the fuel feed pump only has to be plugged onto the shaft and secured. No additional components such as a clutch are necessary. This allows the radial width of the radial piston pump unit to be further reduced.
  • Another advantage that results from the compact arrangement of the high pressure pump and the fuel feed pump is that the line from the fuel feed pump to the suction valve of the high pressure pump can be reduced to a minimum.
  • FIG. 1 shows a longitudinal section through the radial piston pump unit
  • FIG. 4 shows a further illustration of the radial piston pump unit
  • the two cuts are perpendicular to the shaft axis, but are shifted at a certain angle to each other. This is necessary because the individual components of the radial piston pump unit are distributed over the circumference and only in this way can all components be displayed.
  • a drive shaft 2 (FIG. 1) is mounted in the pump housing 1 via a first shaft bearing 9a and a second shaft bearing 9b.
  • the drive shaft 2 has an eccentric section 3.
  • a cam ring 4 is arranged on the eccentric section 3.
  • three spring-loaded pump pistons 5 (FIG. 2), which are movable in the radial direction of the drive axis, are preferably supported.
  • the pump pistons 5 are preferably offset 120 ° from one another, in a radial plane to the axis of the drive shaft 2, in the pump housing 1.
  • the drive shaft 2 has an overhung end region 6, which is also the drive for a fuel feed pump 8. To accommodate the fuel feed pump 8, the overhung end region 6 has a tooth profile 7.
  • the pump housing 1 is designed as a pot housing.
  • the overhung end of the drive shaft 2 sits on the pot side open to the pump housing 1.
  • the open pot side of the pump housing 1 is closed by a flanged pot lid 31.
  • the pot lid 31 is designed such that it simultaneously forms a pump chamber 32 of the fuel feed pump 8.
  • the fuel feed connection 10, a flow channel 12, a lubrication bore 14 and a volume flow control valve 16 are additionally in the pot lid 31 accommodated. This enables a very compact design of the radial piston pump unit.
  • the fuel enters the radial piston pump unit through the fuel inlet connection 10 in the pot cover 31.
  • the fuel reaches the fuel pre-feed pump 8 via the flow channel 12.
  • the flow channel is designed in such a way that the pump chamber 32 can be filled on both sides.
  • the lubrication hole 14 is used to lubricate the fuel feed pump 8.
  • the fuel exits the fuel feed pump 8 at a pressure of about 5-10 bar and from there reaches the volume flow control valve 16, which saves space in the top cover 31 is integrated.
  • the fuel then passes from the volume flow control valve 16 to a control disk 18.
  • the control disk 18 serves to distribute the fuel evenly over the suction valves distributed around the circumference. For this purpose, a circumferential annular groove 19 is provided on the control disk 16.
  • a suction valve 24 and a pressure valve 28 are assigned to each pump piston 5.
  • the suction valve 24 opens and fuel can flow into the cylinder space 26.
  • the fuel in the cylinder chamber 26 is compressed.
  • both the suction valve 24 and the pressure valve 28 are closed.
  • the pressure valve 28 opens and the fuel can flow into the high pressure line.
  • FIG. 3 shows a section through the control disk 18.
  • the section axis is identified in FIG. 2 by the axis EE '.
  • the control disk 16 is fixedly connected to the pump housing 1.
  • the control disk 18 has deformation pockets 33 which allow the control disk 18 to be elastically deformed, in particular when the drive shaft 2 starts up.
  • the control disc 18 has a pressure relief valve 30 for the Fuel feed pump 8 on.
  • a vane pump or a blocking vane pump is particularly suitable as the feed pump.
  • FIG 4 shows a schematic representation of a radial piston pump unit.
  • a flat surfaces 36 and a flat surface 37 are arranged on the outer circumference of the pump housing 1 and serve to receive the pump connections 39 and 40.
  • Below the connections 39 and 40 is the high-pressure accumulator 41 integrated in the pump housing, which is represented by the broken lines.
  • the high-pressure accumulator 41 can advantageously be integrated into the pump housing 1, since the design of the pump housing 1 as a high-pressure-resistant component provides sufficient material reserves at certain points in the pump housing 1 to integrate the high-pressure accumulator 41.
  • the integration of the high-pressure accumulator into the pump housing is advisable if a pressure control valve 42 is simultaneously integrated into the high-pressure accumulator.
  • the high-pressure accumulator 41 is connected to the pressure control valve 42 on the right side in the drawing. On the left side of the drawing there is a line for connection 40
  • the pump housing 1 can be manufactured inexpensively from spheroidal graphite cast iron. If very high pressures are to be achieved with the radial piston pump unit, the pump housing 1 should preferably be made of spheroidal graphite cast iron with a bainitic structure or as a steel forged part.
  • the pot lid 31 can preferably be made of die-cast aluminum or plastic.
  • the control disk 16 can preferably be made of steel, plastic or cast aluminum.
  • a flange can be preferably provided on the pump housing 1 for the direct fastening of the radial piston pump unit to the motor.
