Definitions

  • the invention relates to a filling opening for filling lubricating oil into an internal combustion engine according to the preamble of the main claim.
  • Such filler openings are expediently arranged on the valve chamber cover and generally consist of a tubular filler neck which is closed with a lid with a bayonet lock.
  • the object of the invention is therefore to avoid this disadvantage, i.e. to design the oil filler neck in such a way that it prevents the oil from flowing back into the oil separator.
  • a major advantage of the invention is that no additional measures are required when filling oil, such as closing a valve, but that the effective sealing of the return opening of the oil separator against the fill opening is forced upon opening the fill opening and thus incorrect operation is excluded. Likewise, the release of the return opening takes place without the need for additional handles, so that it is guaranteed in any case that with a closed fill opening the oil collected in the oil separator can flow back into the valve chamber unhindered.
  • closure part designed as a rotary slide valve requires only a very small amount of space and thus the filling of the oil is not hindered by this closure part.
  • the oil separator is arranged in a ring around the filler opening, with several return openings being provided.
  • the closure part is then expediently designed as a sleeve which has a thin wall thickness has and lies against the inside of the wall of the filler opening.
  • This sleeve is provided with openings that open the return openings.
  • Such a sleeve can be inserted in a simple manner during assembly of the filler opening.
  • the closure part remains fixed in this installation position by means of a flange at the lower edge.
  • the operative connection between the closure lid and the closure part consists of a positive, releasable connection which is formed on the closure part by a web-shaped nose, via which a driving fork arranged on the closure lid engages.
  • a positive, releasable connection which is formed on the closure part by a web-shaped nose, via which a driving fork arranged on the closure lid engages.
  • the closure part is provided with cams which engage in recesses in the positions in which the oil separator is closed or open.
  • cams can e.g. be arranged in the plane of the return openings and engage in the return openings in the closed position.
  • closure part has also proven to be advantageous to provide the closure part with a sieve-shaped bottom, provided that the filling opening is not itself equipped with such a bottom.
  • This floor serves to protect the valve chamber against the penetration of solid objects.
  • FIG. 1 the upper part of a valve chamber cover 10 is shown. On this valve chamber cover, a housing 11 is fastened, which encloses a filling opening 12. A sealing ring 13 is provided between the housing 11 and the valve chamber cover.
  • the filling opening 12 is tubular and has an inner part 13 which is welded to the housing 11 at the weld seam 14. Both parts are molded plastic parts.
  • the filling opening 12 can be closed with a closure cap 15.
  • This cover has a conventional bayonet lock.
  • the housing 11 is provided with a coarse grid 16. This coarse grille retains objects that unintentionally get into the filling opening.
  • a cavity 17, which has the function of an oil separator, is located in a ring around the filling opening between the housing 11 and the inner part 13.
  • the oil separator is provided with a first connection piece 19. This connecting piece is connected to the crankcase via a hose connection. The ones in the crankcase themselves Blow-by gases are supplied to the oil separator via this connecting piece 19.
  • a baffle 18 serves to better de-oil the blow-by gases. This baffle 18 is annular and arranged on the inner part 13. In the upper area of the oil separator there are two further connecting pieces 20, 21.
  • the blow-by gas emerges through these two connecting pieces and is led either to the suction pipe via the connecting piece 20 or to the clean air side of the air filter via the connecting piece 21.
  • the throttle valve is closed or not very open, the blow-by gases are fed to the engine via the connecting piece 20 due to the higher negative pressure in the intake manifold.
  • the throttle valve is open, the blow-by gases reach the intake air area via the connecting piece 21 due to the higher negative pressure on the filter clean air side.
  • the oil collected in the oil separator 22 flows back into the valve chamber via openings 23, 24.
  • the closure part is a cylindrical hollow body which has openings 26, 27 aligned in its lower region with the openings 23, 24 and is rotatably fastened within the inner part 13.
  • the closure part 25 is inserted into the housing 11 before the housing 11 is welded to the inner part 13 and is fixed by the flange shoulder 28 after the welding.
  • a flange shoulder 28 prevents the closure part 25 from moving axially.
  • the closure part 25 is rotated. This rotary movement takes place in a positively guided manner via the closure cover 15.
  • a web 29 on the closure part 25 (FIG. 1a).
  • This web is surrounded by a driving fork 30, which is attached to the closure cap 15, so that the rotational movement of the closure cap 15 is transmitted directly to the closure part 25.
  • the closure cover 15 is closed, the closure part 25 is in the position shown in FIG. the openings 23, 24 are free due to the aligned position of the openings 26, 27.
  • the oil collected in the oil separator can run off unhindered. If the cap 15 is opened, this is done by rotating the cap 15 by 90 degrees. This rotation closes the openings 23, 24, so that when the oil is poured back into the oil separator 22, the oil cannot backflow.
  • cams 31, 32 are provided on the closure part 25 in the plane of the openings 23, 24, as shown in FIG. 1c. These cams protrude into the openings 23, 24 in the closed position. This ensures that when the closure lid is placed on the filler opening, the driving fork 30 comes to rest over the web 29 and the closure part 25 is carried along by the rotation of the closure lid.
  • a variant of the closure part 25 is shown in Figure 2.
  • the oil separator is located directly at the fill opening 12, as shown in FIG. 1.
  • a flat closure part 33 is inserted in the inner part 13.
  • This closure part also has a flange shoulder 28 to avoid axial displacement.
  • the flat closure part lies directly on the coarse grid 16 and has a base 34, which is also designed as a coarse grid. In the middle of the bottom 34 this is reinforced and provided with a square opening.
  • a square tube 36 engages in this square-shaped opening. This square tube is arranged on the closure cover 15 and transmits the rotary movement of the closure cover 15 to the flat closure part 33.
  • the function of the flat closure part 33 corresponds to the function of the closure part 25 shown in FIG. 1.
