Definitions

  • the invention relates to an exhaust gas turbocharger for an internal combustion engine according to the preamble of claim 1.
  • EP 0 794 319 A1 describes an exhaust gas turbocharger Internal combustion engine described, which is typically the basic parts Compressor stage, bearing housing and turbine stage shows. Compressor impeller and Turbine impeller sit on a common rotor shaft that runs between the Impellers by means of hydrodynamic bearings, or hydrodynamically in one Bearing body is stored in the bearing housing.
  • the hydraulic bearing, or the Bearing body is preferably connected to the engine lubricating oil circuit connected, but can also be connected to an external oil reservoir become.
  • sealing air is applied on the turbine side in order to avoid Avoid exhaust gases entering the bearing housing.
  • the measuring device has a so-called settling tank. Of another is between the oil drain line of the turbocharger and the a bypass valve at the highest point of the oil drain line of the still tank provided, whereby the oil emerging from the exhaust gas turbocharger immediately the oil pan can be fed.
  • the object of the present invention is therefore to provide an exhaust gas turbocharger to provide a sufficiently large space at the beginning, with this an adequate separation of oil from the lubricating oil system and Air flowing out of the exhaust gas turbocharger via the rotor shaft seals Compressor and turbine in its bearing housing and thus in the oil circuit can reach, can be guaranteed and which also reduces effort can be integrated into the exhaust gas turbocharger.
  • annular space with a complete Separation of oil and air sufficient volume within the bearing housing of the exhaust gas turbocharger is provided, in particular in that the Bearing housing an oil space to accommodate the hydrodynamic bearing Has rotor shaft and the annular space for venting the lubricating oil, the oil space at least partially coaxially, the annular space on the one hand by means of a Overflow from an external oil reservoir, as well as an oil drain to the engine room of the engine and on the other hand connected to the oil space with an oil passage and the bearing housing depending on the volume of the integrated therein Annulus the available space between the compressor and turbine stage fills, is an integrated in the bearing housing ventilation of the oil space for the Storage of the rotor shaft has been created, which in the bearing housing oil mist is made available a sufficiently large space, to accomplish the separation of oil and air. At the same time it will the oil mist can also be used as additional bearing housing cooling.
  • the subject of the invention thus uses that between the turbine and compressor stages available space to make the bearing housing as large as possible design and thus the annular space for venting the lubricating oil, d. H. the Integrate ventilation system in the bearing housing.
  • a preferred embodiment is one Exhaust gas turbocharger according to the invention for an internal combustion engine with a Annulus with a sufficient for the complete separation of oil and air Volume shown within the bearing housing.
  • a meridian section through the exhaust gas turbocharger 1 shows a compressor stage 2, one Turbine stage 3 and a bearing housing 4 arranged between them.
  • a spiral guide channel which is a radial flows through the compressor wheel 5 of the compressor stage 2
  • a guide channel which has a turbine wheel 6 (through which axially flows) encloses, flanged.
  • Ver Whyr- 5 and turbine wheel 6 sit on a common rotor shaft 7, which in known manner by means of hydraulic radial bearings or bushings in Bearing housing 4 is mounted.
  • the hydrodynamic bearing of the rotor shaft 7 is by means of a cylindrical one Bearing body 8 sheathed, which in turn with the formation of an oil space 9 in the Bearing housing 4 is installed.
  • the annular space 10 is partially arranged coaxially around the oil space 9 and on the one hand by means of an overflow 11 with an external oil reservoir, and by means of a Oil drain 12 connected to the engine compartment, and on the other hand with an oil passage can be connected to the oil space.
  • This is the cycle through the rotor shaft seals in the oil chamber 9 penetrating and with the Air located there to an oil mist, air mixed in the annular space 10 by the oil separated again and discharged via the oil drain 12.
  • the one at the Housing walls 4 precipitating oil mist 13 has a cooling effect.
  • the bearing body 8 advantageously installed in the bearing housing 4 is so executed that on the one hand by means of radial bores 20 and an oil groove 21 in Circumference of the cylindrical bearing body, an oil passage from the annular space 10 in the Bearing body 8 and on the other hand via further circumferential openings 22 Oil passage from the bearing body 8 into the oil space 9, which in turn is a Has connection 23 with the annular space 10 of the bearing housing 4, made is.
  • the bearing housing 4 is therefore designed so that it depends on the Volume of the integrated annulus 10 the available space between the Compressor 2 and turbine stage 3 fills.
