    The invention relates to a Brenrkraftmaschine with at least one reciprocating piston for driving a crankshaft, with at least one drive connected to the crankshaft mass balance, with at least one pump, in particular an oil pump, with at least one drive connected to the crankshaft or the balancer shaft rotor. Oil pumps are usually driven by chain or gear wheels. Often, they are driven by the mass balance shaft when it is either installed in the crankcase, or placed in its own mass balance housing.
    A particularly simple drive can be done directly from the crankshaft. In this case, the front end of the crankshaft is pushed through to the oil pump. The housing of the oil pump is combined with the sealing ring carrier and very often carries the front part of the oil pan flange.
    It is known from the publications DE 10 2008 021 528 A1, EP 319 809 A1, EP 1 065 357 A2, EP 1 065 359 A2, US Pat. No. 5,497,747 A, JP 2 2012 642 A2 or US Pat. No. 4,793,301 to use an oil pump of a To drive internal combustion engine by a mass balance shaft. The driven by the mass balance shaft oil pumps usually have their own housing.
    It is also known to integrate oil pumps in the crankcase. Such oil pumps require their own drive by means of gear or chain pinion.
    The object of the invention is to provide a pressure oil supply in an internal combustion engine as simple as possible.
    According to the invention this is achieved in that the pump is integrated in a at least one bearing for the crankshaft or the mass balance shaft receiving structure, wherein preferably at least a part of the structure is a bearing bracket and / or a bearing block and / or a lead frame. The bearing block can be formed integrally with the crankcase. But it is also possible to perform the bearing block as a separate, releasably connected to the crankcase part. • ft * * ϊ.
    The housing of the pump is at least predominantly formed by the structure. It can be provided that the structure forms a niche or a countersink for receiving the at least one rotor of the pump, wherein the niche or the countersink is completed by a pump cover.
    The mass balance shaft is usually axially supported by shoulders on at least one bearing. The shoulders can be omitted if the rotor is pressed onto the mass balance shaft. In this case, the rotor can form the thrust bearing of the mass balance shaft.
    The pump may be formed by an internal gear pump, or else by an external gear pump.
    The fact that the pump is integrated into the bearing of the crankshaft or the mass balance shaft receiving structure, parts and space can be saved. This allows a particularly compact and cost-effective production.
    A particularly simple and parts-saving solution can be achieved if at least one suction channel and / or at least one pressure channel of the pump is integrated into the structure. It can be provided that the pressure channel of the oil pump is fluidly connected to an integrated in an oil pan of the engine oil filter and / or oil cooler.
    In a further embodiment of the invention, it is provided that at least one pressure regulating valve is integrated into the structure receiving the bearing for the mass balance shaft.
    The advantage of the embodiment according to the invention is that no additional drive of the oil pump and no separate housing for the oil pump is required. This achieves a compact and cost-effective solution.
    The invention will be explained in more detail below with reference to FIGS.
    1 shows an internal combustion engine according to the invention in a section along the line I - I in Fig. 2, Fig. 2, the internal combustion engine in a side view, Fig. 3, the internal combustion engine in an oblique view, Fig. 4 in a
    Side view with the pump cover removed and Fig. 5 shows the internal combustion engine in a bottom view.
    The internal combustion engine 20 shown in FIGS. 1 to 5 has pistons 21, which drive a crankshaft 23 mounted in the crankcase 29 via connecting rods 22. Furthermore, the internal combustion engine 20 has at least one mass balance shaft 2, which is drive-connected via gears 13, 14 to the crankshaft 23. The mass balance shaft 2 is supported by bearings 24, 25, 26. At least one bearing 24 is surrounded by a structure 27, which is formed by a bearing bracket 5 and by a bearing block 6. The bearing bracket 5 can also be integrated in a lead frame, not shown. The bearing block 6 may be formed integrally with the crankcase 29 or as a separate part. For axial support of the mass balance shaft 2 shoulders 30 are provided.
    At one end of the mass balance shaft 2, the rotor 8 of a pump 1, which is designed in the present embodiment as a gear pump, pushed onto the mass balance shaft 2. The pump 1 may be, for example, an oil pump for lubricating oil, hydraulic oil, or the like. The entrainment of the rotor 8 of the running as an internal gear pump pump 1 through the mass balance shaft 2 is either non-positively by a press fit of the rotor 8 on the mass balance shaft 2, or positively with a two-sided flattened part 3 of the mass balance shaft 2. A cylindrical countersink 4 in the bearing bracket 5 and Bearing 6 receives both the outer rotor 7, and the inner rotor 8. The two rotors 7, 8 are held by the pump cover 9.
    In the case of the press fit of the rotor 8 on the mass balance shaft 2, the two shoulders 30 on the mass balance shaft 2 accounts and the thrust bearing is formed by the rotor 8.
    In the view shown in Fig. 5 from below, a mammal opening 10 and a pressure port 11 can be seen. From the pressure port 11, the oil is passed through a sealing element in the not shown sump of the engine 20 to external oil filter and oil cooler. If the bearing bracket 5 are combined to form a lead frame, the oil from the pump 1 can be performed directly over the Ölwannenflansch 28 in the oil pan and back into the crankcase 29. «Ftp * • * - * * ·" ** *: ::: • fl · I · «p | "

    In the structure 27 a arranged in a horizontal bore 12 a pressure control valve 12 is further arranged. The pressure control valve 12 can flow when the control pressure, the fluid from the pressure side to the suction side of the pump 1.
    The fact that the pump 1 is integrated in the structure 27 in a bearing bracket 5 and a bearing block 6, can on a separate housing for the pump 1, as well as an additional drive of the Pump 1 can be dispensed with. Thus, a very compact and inexpensive solution can be achieved.
