Definitions

  • the invention relates to a rotary oil separator for cleaning crankcase ventilation gases of an internal combustion engine.
  • crankcase ventilation gas In all internal combustion engines, oil droplets and oil aerosols are part of the blow-by gases from the crankcase ventilation. When these oil-containing gases are introduced into the intake area of the engine, contamination occurs in the downstream components, which adversely affects the function of the engine components. The entrained oil must therefore be removed from the crankcase ventilation gas.
  • crankcase gases oil separation from the crankcase gases is accomplished by means of separators consisting of a knitted fabric of fibers or by means of beam deflections on impact plates or a combination of these methods.
  • separators consisting of a knitted fabric of fibers or by means of beam deflections on impact plates or a combination of these methods.
  • ultrafine filters are used, but they work with a high differential pressure.
  • Cyclone separators require a relatively large installation space and, in principle, operate optimally only at one operating point.
  • Elecrostatic filters require additional electrical power consumption and are relatively expensive.
  • Rotary oil separators in which the oil droplets are ejected by means of paddle wheels, are also known. They are usually powered by electric motors, air turbines or oil pressure turbines.
  • the invention has for its object to provide an oil separator, which ensures almost complete separation of oil from the crankcase ventilation gases under all operating conditions and low differential pressure and can be produced inexpensively.
  • a filter disk is attached to a shaft located in the crankcase such that the crankcase gases must pass through this filter disk.
  • the oil and soot particles deposited on the surface and on the way through the filter disk are spun off through the rotating disk and remain in the crankcase, so that no oil collecting space and no special oil return are required.
  • the self-cleaning power of the rotating filter disk is so great that the differential pressure of the filter does not change significantly even with long running times.
  • a particularly advantageous use of a rotating filter disk provided for the flow through of the gases to be cleaned consists in the separation of oil droplets and oil aerosols from gases of a crankcase ventilation of an internal combustion engine.
  • a filter disk is able to withstand changing load conditions of the internal combustion engine and to permanently clean itself. Therefore, the separation of the oil droplets and oil aerosols from the gases of the crankcase ventilation is virtually maintenance-free. Soot particles are also thrown off the filter disc.
  • the invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below.
  • This shows in a single figure, a filter disk 1 which is mounted on a shaft 2 in the crankcase chamber 5 of an internal combustion engine, not shown.
  • the flow direction of the crankcase ventilation gases is indicated by arrows.
  • the housing bushing 3 is sealed in the crankcase wall 4 and touched with its front side, the filter disk 1.
  • the housing bushing 3 is provided with a drip edge 6, so that when the engine is stopped, the running of the crankcase wall 4 oil does not reach the filter disk 1.
