Definitions

  • the invention relates to one described in the preamble of claim 1 Internal combustion engine with separate hydraulic circuits.
  • Such an internal combustion engine with two separate hydraulic circuits is, for example known from EP-B 0 416 463, which in addition to the lubrication system the machine forming hydraulic circuit one of the control / regulation of a Includes hydraulic circuit serving camshaft angle of rotation adjustment device.
  • Each of the hydraulic circuits is driven separately by the internal combustion engine Pump equipped, namely with a crankshaft driven Oil pump and one of the camshaft of the internal combustion engine driven high pressure pump.
  • the disadvantage here is the installation space required for the separately arranged Pumps as well as the effort involved in mechanical drive connections for example by looking at one according to DE-A 38 40 356 as Lubrication pump for a single-stage internal rotor gear pump serving an internal combustion engine and one according to EP-A 0 712 997 for hydraulic actuation a valve train adjusting device provided, single-stage internal rotor gear pump can illustrate.
  • the invention has for its object for a generic internal combustion engine with separate hydraulic circuits supplied by lubricating oil, in particular different pressures in terms of installation space and drive effort to show favorable pump arrangement.
  • valve-controlled internal combustion engine proposed that the other hydraulic circuit of the control / regulation of a valve train adjusting device, in particular a camshaft angle of rotation adjustment device serves, the separated in the two-stage internal rotor gear pump Hydraulic circuits advantageously used for different pressures are, the control pressure versus the delivery pressure for the lubrication system is chosen larger.
  • the advantageous embodiment also enables that the lubrication system hydraulic circuit when falling below a predetermined Minimum pressure via a controllable 4- / 2-way valve with the hydraulic circuit the valve train adjustment device can be connected, this directional valve to avoid complex pressure lines also in the pump housing is integrated.
  • A, designated two-stage internal rotor gear pump comprises one externally toothed inner rotor 2, with an internally and externally toothed intermediate rotor 3 cooperates, which in turn in a in a pump housing 4th rotatably mounted external rotor 5 engages with internal teeth.
  • separate Pressure connections 6, 7 are with a respective pressure chamber 8, 9 in oil-carrying Connection.
  • a common inlet 12 is provided for suction chambers 10, 11, via the lubricating oil from an oil pan 13 only schematically in FIG indicated, indicated by 14 internal combustion engine.
  • the pressure chamber 8 or the pressure connection is located 6 of the pump stage 15 in a first hydraulic circuit 16 with the associated one Suction chamber 10 or the inlet 12 via a pressure relief valve 17 in oil-bearing connection.
  • the pressure chamber 9 is located in the second hydraulic circuit 18 or the pressure connection 7 of the second pump stage 19 with the suction chamber 11 or the inlet 12 via a pressure relief valve 20 in connection.
  • For saving separate lines include the pressure relief valves 17, 20 of the connection channels in the pump housing 4 arranged integrated.
  • the first hydraulic circuit 16 forms with the Pump stage 15 the lubrication system of the internal combustion engine 14.
  • the separate one second hydraulic circuit 18 with the pump stage 19 is used to supply another Consumer 21, preferably the control of a valve train adjusting device, in particular a camshaft angle of rotation adjustment device.
  • the inventive use of the two-stage internal rotor gear pump 1 for separate hydraulic circuits 16, 18 with different pressures P 1 and P 2 opens up the possibility of giving priority to the lubrication system hydraulic circuit 16 during operation of the internal combustion engine 14 in that this lubrication system hydraulic circuit 16 if the pressure falls below a predetermined minimum pressure - for example approx. 2 bar - can be connected to the hydraulic circuit 18 of the valve train adjusting device 21 via a controllable 4- / 2-way valve 22.
  • this directional valve 22 is also integrated in the pump housing 4
