Definitions

  • the invention relates to a delay part according to the preamble of claim 1.
  • an oil baffle acting as a so-called oil plane which is provided with a flange-shaped edge in a horizontal plane lying between a cylinder block and an oil pan.
  • the oil baffle is provided with oil passages, which directs the back-flowing lubricating oil from a room above the sheet into a room below.
  • the object of the present invention is to largely defoam the foamed oil in an internal combustion engine.
  • the arrangement of the delay part prevents a short-circuit-like suction of foamed oil.
  • the foamed oil dripping from the crankcase must first flow on the delay part up to its boundary and through the oil passages arranged there and under the delay part back to the centrally arranged suction basket. The consequent time delay until the suction causes a good defoaming of the oil.
  • the delay part adjacent to a surface of a horizontal split oil pan provided with seals between the deep part of the oil pan serving as a reservoir and the cover closing it below.
  • the oil flowing back approximately in the middle of the reservoir from the crankcase must be the above Cover the deceleration distance to the suction basket between the deceleration part and the cover in the oil sump.
  • the deceleration part is held on an oil pump and extends to close to the inner edge of the surface provided with seals.
  • the delay part has an opening into which the suction basket is inserted and the edge region of which is detachably connected to a flange of the oil pump.
  • the edge is flange-shaped and braced in the surface.
  • a double-acting seal can be integrated into the border, so that the usual, separate seals are not required.
  • spacer sleeves are integrated in the seal, so that there is a uniform pressure over the entire circumference that prevents the seal from being crushed.
  • the delay part is easy to produce as a stamped part made of sheet metal or as a molded part made of plastic.
  • the seal is then vulcanized together with the spacers as an elastomer.
  • ribs extending in the direction of the opening for the suction basket can be arranged in a simple manner on the underside of the delay part facing the oil sump. These automatically direct the oil in the sump along the suction strainer during acceleration.
  • a deceleration part 1 extends in the housing (not shown in more detail) of an internal combustion engine for a motor vehicle in a plane E1.
  • This level E1 encloses a surface F between the deep part of an oil pan acting as a storage container V for lubricating oil and a cover 2 closing this container downwards.
  • An oil pump 3, which is only indicated, is arranged in the reservoir V above the delay part 1.
  • An opening 4 is provided in a center of the approximately rectangular deceleration part 1, the edge region 5 of which is connected to a flange of the oil pump 3 via screw connections 6.
  • the delay part 1 consists of a stamped blank 7, on the outer, flange-shaped edge 8 a bilateral seal 9 is applied.
  • the seal 9 surrounds the edge 8 in a U-shape and has sealing lips 10.
  • the indentations 11 serve to receive spacer sleeves 13 embedded in the seal 9.
  • the cover 2 is screwed through this to the storage container V and, at the same time, the deceleration part 1 is braced in the area F.
  • a plurality of oil passages 14 are arranged along the parts of the motor vehicle lying in the direction of travel XX of the vehicle Border 8 .
  • the foamed lubricating oil flowing back from the crankcase enters the reservoir V through an inlet located almost centrally above the opening 4, in order to the suction basket 15 in the oil sump S located below the delay part 1 and inserted through the opening 4 from above get, the lubricating oil will inevitably flow from the inlet to the oil passages 14 and from there back to the suction strainer 15. The oil degasses almost completely along this delay line.
  • the oil sump S has a low overall height, so that only a small amount of oil remains between cover 2 and delay part 1.
  • the remaining amount of oil is above level E1 during normal driving and thus also the oil level.
  • Foamed oil freshly flowing into the reservoir V must sink from the oil level to the vicinity of the delay part 1, which means that there is additional time for degassing.
  • ribs 16 can be arranged on the underside of the delay part 1 facing the oil sump S, as shown in broken lines in FIG. 1 and FIG. These run from the boundary 8 in the direction of the opening 4 and forcibly direct the oil along the suction basket 15 during acceleration.
  • the blank 7 is first manufactured as a stamped part with the opening 4, the indentations 11, the oil passages 14 and the openings 12 in one operation.
  • the edge 8 is then extrusion-coated with the seal 9, the spacer sleeves 13 being integrated into the seal 9 at the same time.
  • the material of the seal 9 penetrates the openings 12 during the encapsulation, so that it is secured against slipping.
  • the height H of the spacer sleeves 13 limits the compression of the sealing lips 10 to a dimension when the cover 2 is mounted on the storage container V, which ensures secure sealing on both sides and prevents the seal 9 from being crushed.
