Definitions

  • the invention relates to a crankcase ventilation for internal combustion engines according to the preamble of the main claim and the preamble of the independent claim 2.
  • DE-AS 12 68 902 describes a crankcase ventilation for internal combustion engines.
  • a connecting line leads upwards from a ventilation opening on the crankcase to an intake port.
  • a condensate separating chamber with a knitted filter is arranged in it, an outlet pipe with a shut-off valve leading out of the separating chamber.
  • the separated oil flows back into the crankcase on the wall of the breather nozzle. At higher gas velocities in the vent, however, the oil is prevented from refluxing. It is pulled into the intake manifold by the gas flow and enters the combustion process.
  • the object of the invention is therefore to provide a crankcase ventilation that also works reliably in internal combustion engines for vehicles.
  • the advantage of the invention can be seen in the fact that the arrangement of a plurality of connections or drain lines ensures that the collected oil is reliably drained even when the liquid separator is in a tilted position.
  • the individual drain lines lead into a common line, which then extends back inside the ventilation line into the crankcase.
  • the figure shows an oil separator of a crankcase ventilation for internal combustion engines.
  • the crankcase ventilation consists of a ventilation line 2 starting from a crankcase 1, a funnel-shaped liquid separator 3 with a separator pack 4 and a suction line 5 leading to the air inlet side of a piston machine (not shown).
  • a suitably designed bottom sieve 6 forms in the liquid separator 3 a collecting space 7 for separated liquid in the form of an annular groove. This channel lies in the area of the transition of the liquid separator 3 into the ventilation line 2.
  • a drain line 8 leads from this channel inside the ventilation line 2 back into the crankcase 1.
  • a hose 11 preferably made of an oil-resistant plastic, can be pushed onto the pipe end 10 of the drain line 8 in the area of the crankcase 1.
  • the hose 11 leads into a flow-reduced zone within the crankcase 1.
  • a further drain line 12 is provided parallel to the first drain line 8. This is arranged diametrically opposite. Of course, there is the possibility, for example, to arrange three or four drain lines. This ensures that the liquid in the collecting space 7 differs from the horizontal in almost every one Layer flows out of the oil separator.
  • All drain lines open into a common drain line 13, which - as already mentioned - can be connected to a hose 11.
  • a valve 14 is arranged in the oil separator, which limits the negative pressure which reacts from the suction pipe.
  • This valve consists of a valve seat 15, a rubber-elastic element 16 and a spring 17. At very high negative pressure in the suction line 5, the valve element 16 is moved downward against the spring force of the spring 17 and closes or reduces the passage cross section of the oil separator, so that an impermissibly high negative pressure cannot continue into the crankcase.
  • a membrane vent valve 19 is arranged in the cover 18 of the oil separator. This valve has the task of venting or venting the space located above the membrane 16.
