Definitions
- the invention relates to a lubricant container for an internal combustion engine Motor vehicle according to the preamble of patent claim 1.
- a known lubricant container of this type is Part of a lubricant supply system for internal combustion engines and has, adjacent to a floor, a lubricant suction nozzle, which by means of a connecting line is connected to a lubricant pump.
- a lubricant suction nozzle which by means of a connecting line is connected to a lubricant pump.
- Flow rates of the lubricant in the area of entry into the Connection line result in what creates vortex formation and then, if the level of the lubricating oil is low, which can lead to the lubricant pump Sucking in air.
- the object of the invention is therefore on a lubricant container such Precautions should be taken to ensure that there is a targeted flow and a homogeneous state of the lubricant is reached where it is at the bottom of the lubricant reservoir enters the connecting line.
- the main advantages achieved with the invention are the fact that the Storage device trained retaining element ensures that the sucked Volume of lubricant, especially oil volume, controlled and controlled Flow rate of the lubricant in the area of the opening in the floor of the lubricating oil tank is reduced, causing a swirl formation and, counteracts the intake of air, especially at low oil levels is.
- the jamming device prevents air bubbles largely as a result of lubricant foaming in the direction of the suction point prevented.
- the stowing device itself is simple and easy in the Component that can be integrated into the lubricant reservoir adjacent components of the lubricating oil tank ensure a good function.
- An internal combustion engine which can be installed in a motor vehicle, comprises for lubricating oil supply a lubricating oil container 1, which, because of the shape of a cube designed, upright container walls 2 and a bottom 3 has.
- a lubricating oil pump 6 In the bottom 3 of the lubricating oil tank 1, an opening 4 is provided, to the mediation a line 5 a lubricating oil pump 6 is connected, which relative to Lube oil reservoir 1 sucks medium downwards or towards the outside.
- the Lubricating oil pump 6 is consequently outside the interior 7 of the lubricating oil container 1 arranged.
- the line 5 is with a pipe socket 8 to the opening 4 of the Lubricating oil container 1 brought up, with a circular cylindrical ring piece 9, which is received by a connecting ring 10 of the lubricating oil container 1.
- a lubricating medium retaining element 11 precedes the opening 4, formed as a stowage device 12 and in the interior 7 of the lubricating oil container 1 is arranged.
- the accumulation device 12 acts, guiding the lubricant, adjacent - at a short distance - the opening 4 and has a conical Profile section 13, which faces said opening 4.
- a lateral surface 14 of the profile section 13 extends between a horizontal base plane 15 to to a downward-pointing tip 16.
- the lateral surface 14 is concave, and the tip 16 is rounded.
- the profile section 13 penetrates the opening 4 and extends in some areas also in line 5.
- the ring piece 9 is on the lateral surface 14 facing side 17 rounded, which is determined by a radius R.
- the lateral surface 14 and the rounded side 17 form an annular channel 18.
- the storage device 12 is formed by a rotationally symmetrical body, whose outer diameter Ad is larger than the largest diameter Dg of the opening 4 and the smallest diameter Dk of the ring piece 9 or the pipe socket 8.
