Definitions

  • the invention relates to an internal combustion engine with separate hydraulic circuits described in the preamble of claim 1.
  • Such an internal combustion engine with two separate hydraulic circuits is known, for example, from EP-B 0 416 463, which, in addition to a hydraulic circuit which forms the lubrication system of the machine, comprises a hydraulic circuit which serves to control / regulate a camshaft angle of rotation adjustment device.
  • Each of the hydraulic circuits is equipped with a pump which is driven separately by the internal combustion engine, namely with a lubricating oil pump driven by the crankshaft and a high pressure pump driven by the camshaft of the internal combustion engine.
  • the invention is based on the object of demonstrating a pump arrangement which is favorable in terms of installation space and drive expenditure for a generic internal combustion engine with separate hydraulic circuits supplied with lubricating oil, in particular of different pressures.
  • patent claim 1 being characterized by the use of a two-stage internal rotor gear pump by means of an intermediate rotor with separate pressure connections, each pressure chamber being connected to the respective suction chamber via a pressure relief valve integrated in the pump housing.
  • valve-controlled internal combustion engine it is proposed for a valve-controlled internal combustion engine that the other hydraulic circuit is used to control a valve train adjusting device, in particular a camshaft angle of rotation adjusting device, the hydraulic circuits separated in the two-stage internal rotor gear pump being advantageously used for different pressures, the control / regulating pressure is chosen to be greater than the delivery pressure for the lubrication system.
  • the hydraulic system according to the invention with a two-stage internal rotor gear pump for separate hydraulic circuits further enables the advantageous embodiment that the lubrication system hydraulic circuit with a hydraulic 4/2-way valve when the pressure drops below a predetermined minimum pressure the valve train adjustment device can be connected, this directional valve also being integrated in the pump housing in order to avoid complex pressure lines.
  • a designated with two-stage internal rotor gear pump comprises an externally toothed inner rotor 2, which cooperates with an internally and externally toothed intermediate rotor 3, which in turn engages in an outer rotor 5 with internal teeth, which is rotatably mounted in a pump housing 4.
  • Separate pressure connections 6, 7 are in oil-carrying connection with a respective pressure chamber 8, 9.
  • a common inlet 12 is provided for suction chambers 10, 11, via which lubricating oil is drawn in from an oil pan 13 of an internal combustion engine, which is only indicated schematically in FIG.
  • the pressure chamber 8 or the pressure connection 6 of the pump stage 15 is in an oil-carrying connection in a first hydraulic circuit 16 with the associated suction chamber 10 or the inlet 12 via a pressure limiting valve 17.
  • the pressure chamber 9 or the pressure connection 7 of the second pump stage 19 is connected to the suction chamber 11 or the inlet 12 via a pressure relief valve 20.
  • the pressure relief valves 17, 20 including the connection channels are integrated in the pump housing 4.
  • the first hydraulic circuit 16 with the pump stage 15 forms the lubrication system of the internal combustion engine 14.
  • the separate second hydraulic circuit 18 with the pump stage 19 serves to supply a further consumer 21, preferably to control a valve train adjusting device, in particular a camshaft angle of rotation adjustment device.
  • the pressure limiting valve 17 is preferably set to a pressure of 4-5 bar, whereas the pressure limiting valve 20 in the second hydraulic circuit 18 for the valve train adjusting device 21 is set to a pressure of 7-9 bar, for example.
