Definitions

  • the invention relates to a lubricating oil filling line Internal combustion engine with one installed in its filling area Oil mist separator for crankcase ventilation according to the preamble of claim 1.
  • the invention deals with the Problem, such a generic device for an inexpensive Manufactured from plastic with simultaneous Optimization of the functional properties of this facility to design.
  • the solution according to the invention consists of a generic one Lube oil filling line with the characteristic features of the Claim 1.
  • the return oil can enter a room flow in which the gas pressure is lower than in that Crankcase area from which the oil mist to be freed from oil when performing the Crankcase ventilation is withdrawn.
  • the device according to the invention can be provided anywhere by using one Overflow tank at the drain end of the oil return line be compactly constructed.
  • the lubricating oil filling line can together with the return oil line, one Crankcase ventilation line and the overflow tank as a uniformly manageable, so-called module part is formed be flanged to an internal combustion engine is.
  • the oil mist separator is part of the Lubricating oil filling line formed module, this oil mist separator easily separable with the lubricating oil filling line connected is.
  • a certain vertical distance between the oil mist separator and the bottom of the expansion tank is required so that there is an overpressure in the return oil line counteracting liquid level in the adjacent gas space can train without penetrating so far into the oil mist separator, that its function is impaired.
  • a sufficient one The overflow container must have a filling volume, thus sufficient liquid to balance the gas pressure Rise in the return oil line is available.
  • the aforementioned vertical distance between Oil mist separator and bottom of the overflow tank on the one hand and the filling volume of this container is designed to that in all operating conditions on the one hand just yet no return oil in the oil mist separator prevents the function can flow back or is dammed up there and that on the other hand for a maximum rise of the oil in the return line sufficient liquid in the overflow container is available.
  • the opening of the overflow container is advantageous arranged in the interior of the lubricating oil filling line, that lubricating oil that is poured into the lubricating oil filler pipe will necessarily have to fill the overflow tank. In such an embodiment it is ensured that the invention desired liquid barrier already at commissioning an engine is guaranteed.
  • the connection of the last mentioned line to the Lubricating oil filling line is expediently in the direct Neighborhood to the return oil line.
  • the oil mist separator via a flange connection with in particular plug closures attached to the lines of the lubricating oil filler pipe.
  • the return oil line is inside the lubricating oil filling line. This line can be accessed via a Plug connection to be designed separable.
  • the overflow container is advantageously firmly connectable.
  • the above-described releasable separating connections between The individual parts can be completely trained as a module Part made in a simple manner as a plastic part be that via a flange connection on the internal combustion engine is attachable.
  • a lubricating oil filling line 1 is connected to a flange 2 an area of an internal combustion engine 3 which can be fastened with the crankcase of the internal combustion engine 3 in connection stands. Through an opening in this area of an outer wall of the engine is the inside of the lubricating oil filling line 1 through the flange connection 14 with the crankcase in connection. At the top can be closed by a cover 15 Opening of the lubricating oil filling line 1 can Lubricating oil can be filled.
  • An oil mist separator 5 is connected via a flange connection 4 with the lubricating oil filling line 1 in its upper area releasably connected.
  • the oil mist separator is a particular one Cyclone separator.
  • oil mist separator 5 passes through a Flange connection 4 interruptible crankcase ventilation line 6 the oil mist to be cleared of oil. The one freed from oil Venting air leaves the oil mist separator 5 a nozzle 7.
  • the oil separated in the oil mist separator 5 is over a separable return oil line in the flange connection 4 8 led into the interior of the lubricating oil filling line 1.
  • the overflow tank 9 is with the part of the internal combustion engine 3, on which the lubricating oil filling line 1 is fastened, also attached. This attachment is detachable and is in of the drawing in the area 11 indicated schematically.
  • a detachable connection is indicated schematically in regions 12 between the overflow tank 9 and the lower separable Part of the return oil line 8.
  • the opening of the overflow container 9 is at least in one Partial circumferential area 13 expanded funnel-shaped to thereby when filling the lubricating oil filler line 1 a compulsory one Ensure filling of the overflow tank 9.
  • the vertical distance between the oil mist separator 5 and the bottom of the overflow tank 9 is to be designed such that due to a between the interior of the lubricating oil filling line 1 and the return oil drain chamber of the oil mist separator 5 existing pressure difference none for pressure equalization Oil rising in the return oil line 8 too in the worst operating conditions in the oil mist separator can penetrate. Of course, this must be done also the filling volume of the overflow container 9 accordingly be large.
  • the modular component according to the invention consisting of the Lube oil filling line 1, the oil separator 5, the crankcase ventilation line 6, the return oil line 8 with an associated Overflow container 9 can not even with one Oil dipstick shown may be provided.
