Definitions

  • the invention relates to a pumping device for lubricant of an internal combustion engine, e.g. the Hubkolbengattung according to the preamble of claim 1.
  • a known pumping device, FR 848 159 , for the lubricant circulation in an internal combustion engine has a pressure pump device and a suction pump device.
  • the suction pump device is formed by a plurality of suction pumps, which are spaced from each other and arranged at different suction points of the internal combustion engine. To form the suction pumps and how their drive is accomplished, no information is given in this reference.
  • a lubricant pump device which has a plurality of gear pumps whose gears are arranged coaxially with each other. Furthermore, two shafts on which the gears of two gear pumps are arranged, connected by means of a spline connection.
  • the pumping device comprises highly effective designed as gear pumps suction pumps, which, because having identical components contribute to a cost-effective design.
  • each gear pump with separate suction points of Internal combustion engine connected.
  • the gear pump provided with two intermeshing gears has two separate chambers accommodated in a housing of the gear pump, which are connected to said suction points. These chambers are separated by an intermediate wall which runs at right angles to the central axes of the gears.
  • the intermediate wall is used as a flat disc in the axial groove of the gears and works with an inner wall of the Housing sealing together.
  • the intermediate wall is designed in the manner of a two-part goggles, which parts are assembled in a central longitudinal plane including both central axes of the gears.
  • the pumping device comprises a pressure pump device, not shown, and a suction pump device 3 with which the circulation of the lubricant in the internal combustion engine is ensured.
  • the pressure pump device is arranged on a first longitudinal side and the suction pump device 3 on a second longitudinal side 4 of the crankcase 2.
  • the suction pump device 3 is formed by at least two suction pumps 5, 6, which are connected to suction devices 7, 8 of the internal combustion engine 1.
  • the suction pumps 5,6 are designed as gear pumps 9,10, each having two meshing gears 11,12 and 13,14 and are arranged next to each other, such that the gears 11 and 13 of the gear pumps 9,10 are aligned coaxially with each other and by means of a drive means 15 work together.
  • Each gear pump, for example, 9 has a housing 16 with an approximately oval basic shape, which is provided on end faces 17,18 with housing covers 19,20. In the housing covers 19,20, the gears 11,12 are mounted, wherein the housing 16, the housing cover 19,20 and the gears 11,12 and 13,14 of both gear pumps 9,10 are substantially identical parts.
  • the drive means 15 is a shaft 21 which is in operative connection with the gears 11 and 13 of the adjacent gear pumps 9,10.
  • the shaft 21 has at its ends 22,23 external teeth 24,25 - Fig. 3 - which cooperate with internal gears 26 and 27 of the gears 11 and 13.
  • each gear pump is e.g. 10 with separate suction points 28 and 29 of the suction device 8 - Fig. 1 -.
  • two separate chambers 30 and 31 are provided in the housing 16, which are connected to the suction points 28 and 29 and in which the gears 13,14 of the gear pump 10 are effective.
  • the chambers 30 and 31 in the housing 16 are separated by an intermediate wall 32, which runs at right angles to central axes 33 and 34 of the gears 13,14.
  • the intermediate wall 32 is formed as a flat disc and inserted into grooves 35 and 36 of the gears 13,14, wherein free ends 37 and 38 of the intermediate wall 32 with inner wall portions 39 and 40 of the housing 16 sealingly cooperate.
  • intermediate wall 32 in the manner of a pair of glasses - Fig. 2 - executed, and it consists of symmetrical parts 41,42, which are in one of the two central axes 33 and 34 of the gears 13,14 enclosing central longitudinal plane A-A composed.
