Definitions

the invention relates to a pump device for lubricants of an internal combustion engine e.g. the reciprocating piston type according to the preamble of claim 1.
a known pump device, FR 848 159, for circulating lubricant in one Internal combustion engine has a pressure pump device and a suction pump device on.
the suction pump device is formed by several suction pumps, which are spaced apart and at different suction points of the Internal combustion engine are arranged. To train the suction pumps and how you Drive is accomplished, no information is given in this reference.
the Pump device comprises highly effective suction pumps designed as gear pumps, which, because of identical components, to an inexpensive construction contribute.
Each gear pump with separate suction points is the Internal combustion engine connected.
the one with two intermeshing Gear pump provided two separate in a housing of the gear Gear pump housed chambers that at said suction points are connected. These chambers are separated by an intermediate wall, which in the runs at right angles to the central axes of the gears.
the partition is as flat Washer inserted in the axial groove of the gears and works with an inner wall of the Housing sealing together. After all, the partition is one of two Parts of existing glasses run, which parts in one of both central axes of the Gears including the central longitudinal plane are composed.
the pump device includes one not shown Pressure pump device and a suction pump device 3, with which the circulation of the Lubricant is ensured in the internal combustion engine.
the Pressure pump device is on a first long side and the suction pump device 3 arranged 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 with Suction devices 7, 8 of the internal combustion engine 1 are connected.
the suction pumps 5, 6 are designed as gear pumps 9, 10, each two have intermeshing gears 11, 12 and 13, 14 and next to each other are arranged such that the gears 11 and 13 of the gear pumps 9,10 are aligned coaxially to one another 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 the end faces 17, 18 with housing covers 19, 20. In the housing covers 19, 20, the gear wheels 11, 12 are mounted, the housing 16, the housing cover 19.20 and the gears 11.12 and 13.14 of both gear pumps 9, 10 are essentially identical parts.
the drive means 15 is a shaft 21 which with the gears 11 and 13 of the adjacent gear pumps 9, 10 in operative connection stands.
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.
every gear pump is e.g. 10 with separate suction points 28 and 29 the suction device 8 connected - Fig. 1 -.
the chambers 30 and 31 in the housing 16 are through an intermediate wall 32 separated, which runs at right angles to the central axes 33 and 34 of the gears 13, 14.
the intermediate wall 32 is designed as a flat disc and in grooves 35 and 36 of the Gears 13, 14 are used, with free ends 37 and 38 of the intermediate wall 32 Inner wall sections 39 and 40 of the housing 16 cooperate sealingly.
partition 32 is designed in the manner of glasses - FIG. 2 - and it exists from symmetrical parts 41, 42, which in one of the two central axes 33 and 34 of the Gears 13,14 including the central longitudinal plane A-A are composed.
