Definitions

  • the invention relates to a ventilation device with an integrated oil separator according to the preamble of claim 1.
  • DE-OS 3 509 439 shows a ventilation system for internal combustion engine crankcases, which is provided above a cylinder head and forms a unit with a cover. This design not only takes up a relatively large amount of space in the area of the cylinder head, where a camshaft usually runs, but also impairs the free design of the cover.
  • the object of the invention is therefore to provide a ventilation device with an integrated oil separator for an internal combustion engine which, with good function, is simple and inexpensive to manufacture and can be easily inserted into the crankcase without influencing other components.
  • the ventilation device with integrated oil separator is formed by only two pot-like components, namely an upper part and a lower part, which are easy to manufacture and assemble. As a unit, they can be easily inserted into the crankcase in a wall that extends between V-shaped rows of cylinders of the internal combustion engine.
  • the weight and the manufacturing costs of the ventilation device can be influenced favorably if the upper part and the lower part are made of plastic and are connected to one another by means of a non-detachable plug connection. If the baffles are formed by ribs provided on the upper and lower part, a functional guidance of the ventilation medium is ensured with a good oil separation effect.
  • the ventilation device 1 is attached to a crankcase 2 - Fig. 2 - an internal combustion engine, not shown, and has the task, which occurs in a space 3 of the crankcase 2 when the internal combustion engine is powered, with oil-enriched ventilation medium - it contains blow-by gases - between Dispose of cylinders and pistons in room 3.
  • the oil that is added to the ventilation medium is to be separated, which is done with the oil separator 4, which is integrated in the ventilation device 1.
  • crankcase 2 Between two rows of cylinders 5, 6 arranged in a V-shape, which form a unit with the crankcase 2, this crankcase has an elevation 7 which is delimited by a horizontal wall 8.
  • the wall 8 receives the ventilation device 1 with the oil separator 4 provided with a plurality of baffles 9.
  • the ventilation device 1 and the oil separator 4 are part of a housing 10 which is formed by an upper part 11 and a lower part 12.
  • the upper part 11 has an approximately horizontally extending cover 13 and upright boundary walls 14, 15;
  • the lower part 12 has a bottom 18 which extends transversely to upright boundary walls 16, 17, the boundary walls 16, 17 resting in an opening 10 ′ of the wall 10.
  • the open sides of the upper part 11 and the lower part 12 face each other and the upright boundary walls 14, 15 and 16, 17 overlap.
  • the boundary walls 16, 17 run in sections within the boundary walls 14, 15.
  • the lower part 12 is dimensioned so that there are passage gaps 19, 20 between the boundary walls 14, 15 and 16, 17, respectively, which lead into the interior 21 of the housing 10 lead.
  • the boundary walls 14, 15 of the upper part 11 are supported by flanges 22, 23 on the wall 8 of the crankcase 2 and are fastened at 24, 25, 26 and 27 by means of screws 28.
  • the respective screw 28 penetrates the flange 22 or 23 and is screwed into a thread 29 of the crankcase 2.
  • the upper part 11 and the lower part 12 can each be made of a light metal alloy.
  • screws 30 are used, which are carried out by mutually supporting fastening eyes 31, 32, arranged within the upper part 11 and the lower part 12; Fig. 4.
  • the upper part 11 and the lower part 12 are made of plastic.
  • the lower part 12 has at least one upright receiving part 33, which is led away from the base 18 and has a through-channel 34.
  • a support 36 which is attached to the cover 13 of the upper part 11, is brought up to the receiving part 33 with a shoulder 35.
  • the support 36 has an extension 37, which extends within the through-channel 34 and is supported on its free side 38 with a thickening 39 in a local extension 40 of the through-channel 34.
  • the thickening 39 is produced by heat treatment of the pin 37.
  • connections of the same principle are also provided at 41 and 42.
  • flanges 22, 23 of the plastic upper part 11 in the area of the screws 28 are metallic Support bushings 43 provided.
  • a sealing body 45 can be provided between a support flange 44 of the upper part 11 and the wall 8 of the crankcase 2.
  • the baffles 9 of the oil separator 4 are provided on the upper part 11 and lower part 12 and are formed by webs 46, 47 which overlap in sections. 1, the webs 46, 47 form a type of labyrinth through which the gases of the ventilation medium escape and the oil contained therein is separated.
  • the lower part 12 has an inlet 48 which is provided adjacent to the boundary wall 16.
  • the inlet 48 is provided with a deflecting element 49 which prevents the entry of oil particles into the housing 10 of oil particles accelerated in the direction of rotation A of the crankshaft, not shown.
  • At 50 there is an outlet of the ventilation medium freed from oil, the outlet 50 being attached to the upper part 11 on the side opposite the inlet 48.
  • the outlet 50 comprises a pipe socket 51 which is connected to the intake pipe system of the internal combustion engine, not shown.
  • the bottom 18 of the lower part 12 is provided on opposite sides - seen in the longitudinal direction B-B of the internal combustion engine - with outlet openings 52, 53, which likewise comprise deflecting elements 54 which have the function of the deflecting element 49. So that the medium flows to the oil outlet openings 52, 53, the base 18 has a gradient G angle at least in the transverse direction (FIG. 2) with respect to a horizontal H.
